DESCRIPTION OF EMBODIMENTS

[0205] Examples of timer devices, such as a label assembly, label, or timer assembly will be described in further detail below, including with reference to figures.

[0206] Front and rear views of a label assembly 1000 according to an embodiment of the present disclosure are shown in FIGS. 1a and 1b. The label assembly 1000 includes a first label 1100 and a second label 1200. As explained in further detail below, the first label 1100 includes a first timer to monitor a predetermined time period and a first signalling apparatus that provides an alert signal on expiry of the predetermined time period, and the second label 1200 includes a second tinier to monitor the predetermined time period and a second signalling apparatus that provides an alert signal on expiry of the predetermined time period. The first and second labels 1100, 1200 are releasably connected to each other and are configured to monitor the predetermined time period, starting at the same time.

[0207] In this embodiment, the first label 1100 has a substantially planar configuration, wherein the first label 1100 has a first dimension (e.g. thickness) significantly smaller than its other dimensions (e.g. length and/or width). The first label 1100 may be further configured with substantially rectangular front and rear surfaces 1111, 1112, a first end edge 1113, a second end edge 1114, an inner side edge 1115 and an outer side edge 1116. The length direction of the label 1100 extends between the first and second end edges 1113, 1114 and the width direction of the label 1100 extends between the inner and outer sides edges 1115, 1116.

[0208] Similarly, the second label 1200 has a substantially planar configuration, with substantially rectangular front and rear surfaces 1211, 1212, a first end edge 1213, a second end edge 1214, an inner side edge 1215 and an outer side edge 1216. The length direction of the label 1200 extends between the first and second end edges 1213, 1214 and the width direction of the label 1200 extends between the inner and outer side edges 1215, 1216.

[0209] As indicated, the first and second labels 1100, 1200 are releasably connected to each other. The connection in this embodiment is between the inner side edges 1115, 1215 such that the first and second labels 1100, 1200 are releasably connected in a side-by-side configuration. The releasibility of the connection is provided through the inclusion at the connection of a first line of perforations 1010. The first line of perforations 1010 extends substantially the entire length of the inner side edges 1115, 1215 of the first and second labels 1100, 1200. Thus, the first and second labels 1100, 1200 can be manually disconnected from each other by a user of the label assembly tearing the label assembly 1000 along the first line of perforations 1010. In other embodiments of the present disclosure, the connection between the first and second labels 1100, 1200 may include a frangible element, tear line, tear notch and/or other region of weakness in addition to or as an alternative to perforations. The releasable connection, or perforation 1010, may also be visible to a user thus providing a visual guide to separate the first and second labels.

[0210] As can be seen from the exploded views of FIGS. 2a and 2b, the label 1000 has, primarily, a three-layer construction, including a front panel 1021, a rear panel 1022 and a releasable backing layer 1130. The front and rear panels 1021, 1022 each extend across the full length and width of the label assembly 1000 and are shared by the first and second labels 1100, 1200. The first and second labels 1100, 1200 are therefore integrally formed.

[0211] In the length direction of the first label 1100, the first label 1100 is divided into a first portion 1121 and a second portion 1122, the first and second portions 1121, 1122 being located at opposite sides of a second line of perforations 1123 of the label assembly 1000. The first portion 1121 is located toward the first end edge 1113 of the first label 1100 and the second portion 1122 is located towards the second end edge 1114 of the first label 1100. The second line of perforations 1123 extends between the inner and outer side edges 1115, 1116 of the first label 1100 in the width direction of the label 1100. The first portion 1121 is smaller than the second portion 1122. Both the first portion 1121 and the second portion 1122 extend across the full width of the first label 1100. The second portion 1122 extends across a greater length of the first label 1100 than the first portion 1121. The first portion 1121 is separable from the second portion 1122 by virtue of a user tearing along the second line of perforations 1123.

[0212] In normal use of the label assembly 1000, it is expected that the first and second labels 1100, 1200 will be separated from each other prior to any separation of the first and second portions 1121, 1122 of the first label 1100. To reduce any risk that separating the first and second labels 1100, 1200 along the first line of perforations 1100 could inadvertently cause separation of the first and second portions 1121, 1122, the perforations of the second line of perforations 1123 are distributed less frequently than the perforations of the first line of perforations 1010, rendering the connection between the first and second portions 1121, 1122 stronger than the connection between the first and second labels 1100, 1200.

[0213] The first portion 1121 of the first label 1100 includes a fixing portion to fix the label to a support surface, e.g. after separation of the first and second labels. The fixing portion comprises adhesive in this embodiment to fix the label to the support surface. The adhesive is covered by the backing layer 1130, the backing layer being releasable, e.g. by peeling, to expose the adhesive. The second portion 1121 includes a first electronics unit 1150, the first electronics unit 1150 being described in more detail below.

[0214] The first and second labels 1100, 1200 are each substantially flat, except at a region where each of the labels 1100, 1200 includes a respective housing 1140, 1240 and electronics unit 1150, 1250. In particular, the first label 1100 includes a first housing 1140 for a first electronics unit 1150 and the second label 1200 includes a second housing 1240 for a second electronics unit 1250. The first and second housings 1140, 1240 are each formed by a surface portion of the front panel 1021 and an opposing relief 1141, 1241 formed in the rear panel 1022, the relief 1141, 1241 projecting rearward relative to the remainder of the rear panel 1022.

[0215] The first and second electronics units 1150, 1250 are substantially identical to each other in this embodiment. For simplicity, components and functions of the electronics units are generally discussed below with reference to the first electronics unit 1150 only.

[0216] A close-up view of the first electronics unit 1150 is provided in FIG. 3. The electronics unit 1150 includes a printed circuit board (PCB) 1151 on which a battery 1152 is mounted along with a first LED 1153, a second LED 1154 and a processor (microchip) 1155. The battery 1152 provides a source of power for the LEDs 1153, 1154 and the processor 1155.

[0217] Each of the first and second electronics units 1150, 1250 provide the respective timer to monitor the predetermined time period and the respective signalling apparatus to provide the alert signal on expiry of the predetermined time period. Referring to FIG. 4, which provides a schematic illustration of components of the first electronics unit 1150, the timer is provided at least in part by a timing module 1157 of the processor 1155, and is configured in this embodiment to start timing when electricity is supplied to the processor 1155 from the battery 1152. The signalling apparatus is controlled by a signalling module 1158 of the processor 1155 and provided at least in part by the first and/or second LEDs 1153, 1154.

[0218] Electricity is provided to the processor 1155, and to the LEDS 1153, 1554, via an electrical circuit including the PCB 1151. Referring again to FIG. 3, the electrical circuit is connected to the battery 1152 by a first electrical contact (not visible) and a second electrical contact 1156. The first electrical contact is positioned on the PCB 1151, underneath the battery 1152, to electrically contact a first terminal of the battery 1151. The second electrical contact 1156 is provided by a flexible conductive arm that forms a bridge from the PCB 1151 over the battery 1152 to electrically contact a second terminal of the battery 1152. The second electrical contact 1156 also clips the battery 1152 in place, holding it firmly in position against the PCB 1151.

[0219] In this embodiment, the label assembly 1000 includes a common actuator 1030 to initiate the monitoring of the predetermined time period by the first and second timers of the first and second labels 1100, 1200. Referring to FIG. 1b, for example, the common actuator is provided by a tab 1030 and specifically a bifurcated tab 1030. The tab 1030 has a first proximal end 1031 that extends into the first housing 1140 and a second proximal end 1032 that extends into the second housing 1240. The tab 1030 comprises a bridge section 1033 that extends between and connects together the first and second ends 1031, 1032. The tab 1030 comprises a third, distal end 1034 that is connected to the bridge section 1033 and which is engageable by the user to pull the tab 1030.

[0220] Referring to FIG. 3, the first end 1031 of the tab 1030, which is non-conductive, is positioned under the battery 1152 between the first terminal of the battery 1152 and the first electrical contact of the PCB 1151. While the first end 1031 is in this position, the first electrical contact is insulated from the first terminal of the battery 1152 by the tab 1030 and the electrical circuit is therefore incomplete (open). In this state, electricity cannot flow from the battery 1152 to other components of the electronics unit including the processor 1155. However, when the first end 1031 of the tab 1030 is removed, e.g. as a result of a user pulling the third end 1034 of the tab 1030 in a direction 1040 away from the electronics unit 1150 as indicated in FIG. 1b, the first terminal of the battery 1152 and the first electrical contact are configured to touch so as to complete (close) the electrical circuit. When complete, electricity can flow from the battery 1152 to the processor 1155, which can provide a trigger to initiate monitoring of the predetermined time period by the first timer.

[0221] This arrangement is repeated in the second label 1200, between the corresponding components of the second electronics unit 1250 and the second end 1032 of the tab 1030.

[0222] The LEDs 1153, 1154 are each visible at the front surfaces 1111, 1211 of the first and second labels through translucent material that is at least partially used to form the first panel 1021 of the label assembly 1000.

[0223] Example use of the label assembly 1000 is now described with reference to FIGS. 5a to 5e. In this example, the label assembly 1000 is a shipping label assembly, and the predetermined time period that is to be monitored by the first and second labels 1100, 1200 relates to an item that is shipped from a dispatch location.

[0224] Referring to FIG. 5a, a user can hold the label assembly 1000 in one hand and pull the tab 1030 with their other hand, in a direction generally indicated by arrow 1040, so that it releases from the first and second electronics units 1150, 1250 located within the first and second housings 1140, 1240 and initiates monitoring of the predetermined time period by the first and second timers at the same time.

[0225] Referring to FIG. 5b, a user can then disconnect the first and second labels 1100, 1200 from each other by tearing the label assembly 1000 along the first line of perforations 1010. (In alternative embodiments, a user may disconnect the first and second labels prior to initiating monitoring of the predetermined time period by the first and second timers.)

[0226] Referring to FIG. 5c, a user, at the despatch location for the item, can fix the first label 1100 to a surface such as a whiteboard 1300 (or wall, notice board, or other surface that is readily observed or observable) and fix the second label 1200 to a shipping parcel or crate 1400 that contains the item relating to which the predetermined time period is monitored. In particular, in this example the second label 1200 is located in a pouch 1410 that is fixed to an outer surface of the crate 1400 and which may also contain shipping documentation, etc. The item may then be shipped, as generally represented by arrow 1420 in FIG. 5c, to its intended destination.

[0227] A representation of the first and second labels 1100, 1200, at different locations, is provided in FIG. 5d. In FIG. 5d, it can be seen that different information is printed on the first and second labels 1100, 1200. For example, the specific predetermined time period 1161, 1261 that the labels 1100, 1200 are configured to monitor is printed on each label 1100, 1200 (in this example the time period is 48 hours). Further, on the second portion of the first label 1100, a section 1162 is provided where a user can write information on the first label 1100, including, for example, any one or more of: the time and date of dispatch, the name of the sender, the name of the intended recipient, an indication of whether the item was received in time, the time of receipt, the date of receipt, and a signature, etc. Moreover, on each label 1100, 1200, information 1163, 1263 is printed to help a user interpret alerts provided by the signalling apparatus, and particularly light signals 1164, 1264 emitted from the first and/or second LEDs of the signalling apparatus of each label 1100, 1200.

[0228] In this embodiment, three different types of alert signals are provided by the labels 1100, 1200 of the label assembly 1000: flashing green light; flashing green and red light; and flashing red light. The flashing green light is issued during a first time portion following initiation of monitoring of the predetermined time period (in this example from 0 hours to 30 hours), indicating that there is still a considerable amount of the predetermined time period that remains The flashing green and red light is issued during a second time portion that follows the first time portion and is prior to expiry of the predetermined time period, providing a warning that expiry of the predetermined time is relatively soon or imminent. Finally, the flashing red light is issued upon expiry of the predetermined time period.

[0229] Prompted by the alert signals from the labels 1100, 1200, a user may elect to perform a check in relation to the shipped item or take other action. For example, based on alert signals from the first label 1100, a person at the despatch location may check records or even contact the intended recipient and/or shipping contractor to determine if the item has been received in suitable time, to determine it the item is due to be received in time and/or to determine if a necessary action has been taken in relation to the received item. As another example, based on alert signals from the second label 1100, a shipping contactor may choose to expedite delivery of the item.

[0230] As described above, the first label 1100 includes a first portion 1121 and a second portion 1122, which are separable from each other. The first portion 1121 is fixed, using the adhesive, to the support surface (e.g. the whiteboard 1300 as shown in FIG. 5c), On the other hand, the second portion 1122 does not comprise any adhesive and can be separated, after expiry of the predetermined time period, along the second line of perforations 1123, from the first portion 1121, generally as illustrated in FIG. 5e. The first portion 1121 can therefore remain as a record for the monitoring of the predetermined time period. The first portion 1121 may be retained on the support surface 1300 or moved to another surface, e.g. to a records folder. On the other hand, the second portion 1122, including the relatively bulky electronic elements, can be disposed of, e.g., using appropriate c-waste or e-recycling techniques.

[0231] A label assembly 2000 according to another embodiment of the present disclosure is illustrated in FIGS. 6a and 6b. The label assembly 2000 includes a first label 2100 and a second label 2200 and is substantially identical in form and function to the label assembly 1000 described above, except with regards the actuator to initiate the monitoring of the predetermined time period by the first and second timers of the first and second labels 2100, 2200. In this embodiment, the label assembly 2000 includes two separate actuators, rather than a common actuator, to initiate the monitoring of the predetermined time period by the first and second timers of the first and second labels 2100, 2200. The actuators are provided by a first tab 2130 and a second tab 2230. The first tab 2130 has a proximal end 2131 that extends into the first housing 2140 of the first label 2100 to interact with the electronics unit within the first housing 2140 and an opposite distal end 2132 that is engageable by the user to pull the tab 2130. Similarly, the second tab 2230 has a proximal end 2231 that extends into the second housing 2240 of the second label 2200 to interact with the electronics unit within the second housing 2240 and an opposite distal end 2232 is engageable by the user to pull the tab 2230. The arrangement of tabs 2230, 2240 enables a user of the label assembly to initiate monitoring of the predetermined time period by the first and second timers by pulling the tabs 2130, 2230 simultaneously or in quick succession, effectively causing the timers to monitor the predetermined time period at the same time.

[0232] A label assembly 3000 according to yet another embodiment of the present disclosure is illustrated in FIGS. 7a, 7b and 7c. The label assembly 3000 includes a first label 3100 and a second label 3200 and is similar in form and function to the label assembly 2000 described above with reference to FIGS. 6a and 6b, except that: the first and second labels 3100, 3200 are positioned in a stacked, back-to-back configuration, rather than being side-by-side; and the common actuator, provided by a single tab 3030 in this embodiment, loops between the first and second housings 3140, 3240 of the first and second labels 3100, 3200. The user may place a finger underneath the loop of the tab 3030 to pull the tab from the housings 3140, 3240. By positioning the first and second labels 3100, 3200 back-to-back (or front-to-front, front-to-back or back-to-front in alternative arrangements), storage and/or distribution of the label assembly 3000 may be more convenient. The labels 3100, 3200 are positioned in an aligned arrangement as shown in FIG. 7c, with the first and second housings 3140, 3240 directly opposing each other. In alternative embodiments, the labels 3100, 3200 may be misaligned, e.g. vertically misaligned, so that the first and second housings 3140, 3240 are positionable in an interleaved configuration, enabling a depth of the label assembly to be reduced in size.

[0233] A label assembly 4000 according to another embodiment of the present disclosure is illustrated in FIGS. 8a and 8b. The label assembly 4000 includes a first label 4100 and a second label 4200 and is similar to the label assembly 2000 described above with reference to FIGS. 6a and 6b, except that: the first and second housings 4140, 4240, containing the electronics units, are oriented differently; and, related to this, the distal ends 4132 of the first and second tabs 4130, 4230 that extend from the housings are fixed to the respective opposing label 4100, 4200. In particular, the first tab 4130 has a proximal end 4131 that extends into the first housing 4140 of the first label 4100 to interact with the electronics unit within the first housing 4140 and an opposite distal end 4132 that is fixed to the second label 4200. Similarly, the second tab 4230 has a proximal end 4231 that extends into the second housing 4240 of the second label 4200 to interact with the electronics unit within the second housing 4240 and an opposite distal end 4232 that is fixed to the first label 4100. The distal ends 4132, 4232 can be fixed to the respective first and second labels 4100, 4200 by being sandwiched and/or adhered between panels that form the first and second labels 4100, 4200. The arrangement of tabs 4130, 4230 is such that, when the first and second labels 4100, 4200 are disconnected, e.g. along a line of perforations 4010 between the first and second labels 4100, 4200, and pulled away from each other, the first and second tabs 4130, 4230 are automatically pulled from their respective housings 4140, 4240. Thus, the step of disconnecting the first and second labels 4100, 4200 from each other causes initiating of the monitoring of the predetermined time period by the first and second labels 4100, 4200.

[0234] A label assembly 5000 according to yet another embodiment of the present disclosure is illustrated in FIGS. 9a and 9b. The label assembly 5000 is similar to the label assembly 2000 described above with reference to FIGS. 6a and 6b, except that the releasable backing layer 5030 that covers the adhesive fixing portion of the first label 5100 extends across both labels 5100 and 5200 of the label assembly 5000, and the first and second tabs 5130, 5230 that extend from the first and second housings 5140, 5240 are each fixed to the backing layer 5030. In particular, the first tab 5130 has a proximal end 5131 that extends into the first housing 5140 of the first label 5100 to interact with the electronics unit within the first housing 5140 and an opposite distal end 5132 that is fixed to the backing layer 5030. Similarly, the second tab 5230 has a proximal end 5231 that extends into the second housing 5240 of the second label 5200 to interact with the electronics unit within the second housing 5240 and an opposite distal end 5232 that is fixed to the backing layer 5030. The arrangement enables a user of the label assembly 5000 to initiate monitoring of the predetermined time period by the first and second timers by releasing the backing layer. Releasing (e.g. peeling) of the backing layer 5030 causes the first and second tabs to be automatically pulled from their respective housings 5140, 5240. In this arrangement, the combination of the first and second tabs 5130, 5230 and the backing layer 5030 can be considered to provide a common actuator to initiate monitoring of the predetermined time period.

[0235] Front and rear views of a label 6000 according to another embodiment of the present disclosure are shown in FIGS. 10a and 10b. Like preceding embodiments, the label 6000 includes a timer to monitor a predetermined time period and a signalling apparatus that provides an alert signal on expiry of the predetermined time period.

[0236] The label 6000 has a substantially planar configuration, with substantially rectangular front and rear surfaces 6011, 6012, a first end edge 6013, a second end edge 6014, a first side edge 6015 and a second side edge 6016. The length direction of the label 6000 extends between the first and second end edges 6013, 6014 and the width direction of the label 6000 extends between the first and second side edges 6015, 6016.

[0237] In the length direction of the label 6000, the first label 6000 includes a first portion 6021, a second portion 6022 and a third portion 6023, the first portion 6021 being located towards the first end 6013 of the label 6000, the second portion 6022 being located towards the second end 6014 of the label 6000 and the third label portion 6023 being located between the first and second label portions 6021, 6022.

[0238] In this embodiment, a first line of perforations 6024 extends between the first and second side edges 6015, 6016 of the label 6000 in the width direction of the label 6000, directly between the first and third label portions 6021, 6023, and a second line of perforations 6025 extends between the first and second side edges 6015, 6016 of the label 6000 in the width direction of the label 6000, directly between the second and third label portions 6022, 6023. The third label portion 6021 is therefore separable from the first and second label portion 6021, 6022 by a user tearing along the first and second lines of perforations 6024, 6025.

[0239] The first and second label portions 6021, 6022 include respective first and second fixing portions 6031, 6032 to fix the label 6000 to a support surface. In this embodiment, the first and second fixing portions 6031, 6032 each comprise a layer of adhesive covered by a releasable backing layer. The backing layers are releasable, e.g. by peeling, to expose the adhesive.

[0240] The label 6000 is substantially flat, except at a region where it includes a housing 6040, an electronics unit 6050 (see FIG. 11) being located in the housing 6040. In this embodiment, the housing 6040 and electronic unit 6050 are provided in the third portion 6023 of the label 6000. The housing 6040 and the electronics unit 6050 are formed in a similar or identical manner to the housing 1140 and electronics unit 1150 described above with reference to FIGS. 2a to 4. The electronics unit 6050 again comprises the timer to monitor the predetermined time period and the signalling apparatus that provides an alert signal on expiry of the predetermined time period. In this embodiment, the alert signal is provided by one or more LEDs that are visible through a window 6027 at the front surface of the third label portion 6023.

[0241] The label 6000 includes an actuator to initiate the monitoring of the predetermined time period by the timer. In this embodiment, the actuator is provided by a tab 6060. The tab 6060 has a proximal end 6061 that extends into the housing 6040 to interact with components of the electronics unit 6050 within the housing 6040 and an opposite distal end 6062 that is engageable by the user to pull the tab 6060 from the housing 6040. Pulling the tab 6060 can initiate the monitoring of the predetermined time period by allowing completion of an electrical circuit in the electronics unit 6050 in a similar manner to that described above with reference to the electronics unit 1150 of FIG. 3. Although an actuator in the form of a tab is described in this and various other embodiments, the actuator in this and other embodiments may alternatively comprise a button or a slider that is pressed or slid by a user to initiate the monitoring, or may comprise a magnetic switch that is operable by moving relative to or into a magnetic field. Other types of actuators may also be used.

[0242] The label 6000 is configured so that the first and second fixing portions 6031, 6032 can fix the label 6000 to a support surface in a secure manner, the fixing occurring at either side of the third label portion 6023 that includes the electronics unit/timer. Fixing of the label 6000 to a support surface 6070, using the first and second fixing portions 6031, 6032 is illustrated in FIG. 11. Using the first and second fixing portions 6031, 6032 to fix the label 6000 to a support surface 6070 contrasts, for example, with an arrangement where a label is fixed to a support surface using a fixing portion to one side of the electronics unit/timer only, e.g., as described in preceding embodiments. Using the first and second fixing portions 6031, 6032 may reduce the risk that the label 6000 is unintentionally released from the support surface 6070, e.g., by a loose end of the label 6000 being caught and/or pulled by mistake.

[0243] As can be seen in FIG. 11, the housing 6040 containing the electronics unit 6050 is situated at a rear of the label 6000 where it faces or even contacts the support surface 6070. So that the tab 6060 is accessible to a user when the label 6000 is fixed to the support surface 6070, the distal end 6062 of the tab 6000 extends through an opening 6026 in the label 6000 to the front side of the label 6000, the opening 6026 reaching between the front and rear surfaces 6011, 6012 of the label 6000 and specifically at the second label portion 6022 of the label 6000 in this embodiment. Thus, the tab 6060 is connected to the electronics unit 6050 at the rear surface 6012 of the label 6000 while being accessible from the front surface 6011 of the label 6000 to the user.

[0244] With reference to FIG. 12a, in use the label 6000 may be fixed, using the first and second fixing portions 6022, 6023, in one example, to an item that is shipped, such as a parcel, a crate or a container 6080 as represented in this embodiment. The user can initiate monitoring of the time period after a product is packed in the container 6080, for example. The label 6000 may be selected to monitor a predetermined time period that is based on a period by which the contents of the container 6080 is guaranteed to be safely kept at temperature, for example. The contents may include, for example, biological material such as tissue grafts or non-medical items such as food or otherwise. The container 6080 may provide for cold-transport of a product, such as biological material or food, for example.

[0245] Before or after the label 6000 is fixed to the container 6080, the user can initiate monitoring of the predetermined time period by pulling and removing the tab 6060, as shown in FIG. 12b. In this embodiment, two different types of visual alert signals are provided by LEDs included in the electronics unit 6050 of the third label portion 6023. A green light is issued during a first time portion following initiation of monitoring of the predetermined time period, up to expiry of the predetermined time period and a red light is issued following expiry of the predetermined time period.

[0246] After expiry of the predetermined time period and/or after any necessary action has been taken in relation to the container 6080, e.g., delivery of the container, removal of the contents of the container, or use of the contents, the third label portion 6023 can be removed from the label 6000, as illustrated in FIG. 12c. Removal can be carried out by tearing the label across the first and second lines of perforations 6024, 6025. Removing of the third label portion 6023 may allow the container 6080 to be recycled or otherwise disposed of without complications that might be caused by electronic components being attached to the item 6080. Additionally or alternatively, it can allow the electronic components to be recycled or otherwise disposed of in an appropriate manner. The first and second label portions 6021, 6022 may remain fixed to the item 6080 during recycling or disposal.

[0247] Front and rear views of a label 7000 according to another embodiment of the present disclosure are shown in FIGS. 13a and 13b. The label 7000 is very similar to the label 6000 described with reference to FIGS. 10a to 12c, except that its third label portion 7023 is not only positioned between first and second label portions 7021, 7022, located on opposite sides of the third label portion 7023 in a first direction of the label 7000, but is also positioned between fourth and fifth label portions 7024, 7025 located on opposite sides of the third label portion 7023 in a second, transverse, direction of the label 7000. The periphery of the third label portion 7023 is therefore entirely surrounded by other portions of the label 7000.

[0248] In this embodiment, first and second fixing portions 7031, 7032 comprised in the first and second label portions 7021, 2022 are joined together by virtue of fourth and fifth fixing portions 7034, 7035 comprised in the fourth and fifth label portions 7024, 7025. The periphery of the third label portion 7023 is therefore entirely surrounded by fixing portions of the label 7000. The fixing portions are provided by different regions of an adhesive layer (optionally covered by a backing layer) that entirely surrounds the third label portion 7023. Again, however, the third label portion 7023 does not include any fixing portion.

[0249] In this embodiment, after monitoring of a predetermined time period, again through use of an electronics unit comprised in a housing 7040, the monitoring being initiated by pulling of a tab 7060, the third label portion 7023 is separable from the first and second label portions 7021, 7022 (and also from the fourth and fifth label portions 7024, 7025) by virtue of tearing across lines of perforation 7026 that extend between the label portions. To assist a user with engaging and tearing off the third label portion 7023, a further tab 7027 is provided, that is fixed to and projects from the third label portion 7023. In this embodiment, the lines of perforation 7026 may define a periphery of the third label portion 7023.

[0250] Labels 8000, 9000 according to two further embodiments of the present disclosure are illustrated in FIGS. 14a to 15b. The label 8000 illustrated in FIGS. 14a and 14b is substantially identical to the label 6000 described above, the label 8000 including first and second label portions 8021, 8022, having discrete first and second fixing portions 8031, 8032 and a third label portion 8023 comprising a timer and signalling apparatus that is connected to and located between the first and second label portions 8021, 8022. However, the label 8000 does not include any regions of weakness (e.g. lines of perforation) to enable manual separation of the first and second label portions 8021, 8022 from the third label portion 8023. Similarly, the label 9000 illustrated in FIGS. 15a and 15b is substantially identical to the label 7000 described above, the label 9000 including first and second label portions 9021, 9022, having conjoined first and second fixing portions 9031, 9032, and a third label portion 9023 comprising a timer and signalling apparatus that is connected to and located between the first and second label portions 9021, 9022. However, the label 9000 does not include any regions of weakness (e.g. lines of perforation) to enable manual separation of the first and second label portions 9021, 9022 from the third label portion 9023.

[0251] A timer assembly 10100 according to an embodiment of the present disclosure is illustrated in FIGS. 16a and 16b. The timer assembly includes a base 10200 and a timer unit 10300. As discussed in more detail below, the timer unit 10300 is movable relative to the base 10200, and in particular is slidable relative to the base 10200. Sliding of the timer unit 10300 relative to the base 10200 is used to initiate monitoring of a predetermined time period by an electronic timer of the timer unit 10300, the timer unit 10300 also including signalling apparatus that provides an alert signal on expiry of the predetermined time period.

[0252] The base 10200 of the timer assembly 10100 is shown in more detail in FIGS. 17a and 17b and FIGS. 20a to 20c. The base 10200 in this embodiment has a substantially elongate, planar configuration with substantially flat front and rear surfaces 10201, 10202, curved first and second end surfaces 10203, 10204 and substantially straight first and second side surfaces 10205, 10206. The configuration of the end and side surfaces 10203-10206 provides the base 10200 with a substantially oblong profile. The length direction of the base 10200 extends between first and second end surfaces 10203, 10204, and the width direction of the base 10200 extends between the first and second side surfaces 10205, 10206. Each of the side surfaces 10205, 10206 has a respective groove 10210, 10211 that extends along a length of that side surface 10205, 10206. Front edges of the grooves 10210, 10211 are partially defined by raised regions 10212a, 10212b, 10213a, 10213b of the side surfaces 10205, 10206. The first side surface 10205 has a pair of the raised regions 10212a, 10212b separated by a gap 10214 at a central region of the first side surface 10205. Similarly, the second side surface 10206 has a pair of the raised regions 10213a, 10213b separated by a gap 10215 at a central region of the second side surface 10206.

[0253] Referring to FIGS. 18a and 18b, the timer unit 10300 has a substantially disc-shaped configuration, with front and rear surfaces 10301, 10302 and a substantially circularly extending side surface 10303. As seen in FIG. 18b, the rear surface 10302 of the timer unit 10302 defines a channel 10311 that extends across a length of the timer unit 10300 between first and second ends 10304, 10305. The channel 10311 is defined by a bottom surface portion 10312 and opposing side surface portions 10313, 10314. In this embodiment, the rear surface 10302 of the timer unit 10300 also includes two tabs 10320, 10321 that extend partially over the channel 10311. Each tab 10320, 10321 overhangs a respective one of the side surface portions 10313, 10314.

[0254] Referring to FIGS. 16a and 16b, and FIGS. 19a to 20c, the timer unit 10300 is slidably mounted to the base 10200. The slidable mounting is achieved through insertion of the base 10200 into the channel 10311 of the timer unit 10300. Once the base 10200 is inserted into the channel 10311, the tabs 10320, 10321 of the timer unit 10300 can extend into and contact the grooves 10210, 10211 at the side surfaces of the base 10200, wherein the raised regions 10212a, 10212b, 10213a, 10213b, provide abutment surfaces for the tabs, preventing lifting of the timer unit from channel 10311, The grooves 10210, 10211 provide a track along which the tabs 10320, 10321 slide during sliding of the timer unit 10300 relative to the base 10200, the sliding providing for linear relative movement between the timer unit 10300 and the base 10200.

[0255] The above-described configuration enables the timer unit to move relative to the base, while remaining in contact with the base, between a first position as shown in FIGS. 19a and 20a and a second position as shown in FIGS. 19b and 20b. At the first position, the timer unit 10300 is positioned adjacent the first end 10203 of the base, At the second position, the timer unit 10300 is positioned adjacent the second end 10204 of the base, opposite to the first end of the base. As described in more detail below, movement of the timer unit 10200 to the second position initiates monitoring of the predetermined time period by the electronic timer of the timer unit 10300.

[0256] Thus, in this configuration, a user may conveniently initiate monitoring of the predetermined time period by simply sliding the timer unit relative to the base, whereupon the timer assembly will also provide a visual indication as to whether the monitoring has begun by the position of the timer unit. As a result of the simplicity, the user may be less likely to forget to initiate monitoring, which in turn may reduce a risk of the patient contracting a HAI for instance.

[0257] An exploded view of the timer unit is shown in FIG. 21. The timer unit includes a housing and in particular a casing having a front shell 10330 and a rear shell 10331, the front and rear shells 10330, 10331 being fixed together to define an internal chamber in which electrical components of the timer unit 10300 are located. The electronic components include a printed circuit board (PCB) 10332 on which a battery 10340 is mounted along with first, second, third, fourth and fifth LEDs 10341, 10342, 10343, 10344, 10348, a processor (microchip) 10345 and a magnetic switch 10346. The first, second, third and fourth LEDS 10341, 10342, 10343, 10344 are distributed around a periphery of the PCB 10332 and align with an annular window 10349 located at the periphery of the front surface 10301 of the timer unit 10300. The fifth LED 10348 aligns with a small circular window 10350 on the front surface 10301 of the timer unit 10300. The battery 10340 provides a source of power for the LEDs 10341, 10342, 10343, 10344, 10348 and the processor 10345. Additional LEDs may be provided to provide other information, such as a low battery level warning.

[0258] A schematic illustration of the electronic components is provided in FIG. 22, The electronic timer of the timer unit 10300 is provided at least in part by a timing module 10350 of the processor 10345, and is configured in this embodiment to initiating monitoring of the predetermined timer period when electricity is supplied to the processor 10345 from the battery 10340. The signalling apparatus of the timer unit is controlled by a signalling module 10351 of the processor 10345 and provided at least in part by the four LEDs 10341, 10342, 10343, 10344.

[0259] Electricity is provided to the processor 10345, and to the LEDS 10341, 10342, 10343, 10344, 10348, via an electrical circuit that includes the magnetic switch 10346, and specifically a reed switch. When the magnetic switch 10346 is in a closed (on) state, electricity can flow from the battery 10340 to the processor 10345, which initiates monitoring of the predetermined time period by the electronic timer, When the magnetic switch is in an open (off) state, electricity cannot flow from the battery 10340 to the processor 10345, preventing monitoring of the predetermined time period by the electronic timer. In this embodiment, the electronics are configured so that placement of the magnetic switch in the off state resets the monitoring of the predetermined time period. Thus, when the magnetic switch is transitioned from the off state to the on state, monitoring of the predetermined time period will always start from the beginning of the predetermined time period.

[0260] The magnetic switch 10346 is automatically transitioned to its on state when the timer unit 10300 is moved to the second position relative to the base 10200 (where it is positioned adjacent the second end 10204 of the base 10200). As seen in FIG. 23, the base 10200 includes a first magnet 10220 located in a recess 10221 adjacent the second end 10204 of the base, the recess 10221 and the first magnet 10220 being covered by a rear panel 10222. Therefore, when the timer unit 10300 is moved to the second position relative to the base 10200, the magnetic switch 10346 can be substantially aligned with the first magnet 10220, causing the switch 10346 to transition to the on state, initiating monitoring of the predetermined time period. Such alignment of the magnetic switch 10346 and the first magnet 10220 can be seen in FIG. 24b. Consequently, any movement of the timer unit 10300 from the second position towards the first position causes misalignment of the magnetic switch 10346 and the first magnet 10220, transitioning the switch 10346 to the off state.

[0261] Upon initiation of the monitoring of the predetermined time period, the signalling module 10351 causes the fifth LED 10348 to be lit to indicate that the time period is being monitored and the time period has not yet expired. The fifth LED 10348 can emit the light in a continuous or flashing mode and, in this embodiment, is configured to emit green light. After expiry of the time period as monitored by the timer, the signalling module 10351 switches off the fifth LED 10348 and switches on, in a repeating, sequential pattern, the first, second, third and fourth :LEDs 10341, 10342, 10343, 10344, thus providing an alert to the user that the predetermined time period has ended and that appropriate action needs to be taken. The repeating, sequential operation of the first, second, third and fourth LEDs 10341, 10342, 10343, 10344, which are visible via the annular window 10349, provides the user with a perception of a visible, scrolling alert signal. In this embodiment, the first, second, third and fourth LEDs 10341, 10342, 10343, 10344 emit red light. Additional LEDs may be provided, e.g. 8 evenly-distributed LEDs, to provide a more continuous scrolling sensation.

[0262] To prevent inadvertent movement of the timer unit 10300 from either one of the first and second positions, the timer assembly 10100 is configured so that a moderate amount of force must be applied to move the timer unit 10300 between the first and second positions. Any inadvertent movement of the timer unit 10300 away from the first position or the second position could otherwise cause unintended initiation of monitoring of the predetermined time period or unintentional cessation of monitoring of the predetermined timer period. In this embodiment, a moderate force must be applied to the timer unit 10300, e.g. by hand, to overcome a magnetic attraction the releasably holds the tinier unit 10300 to the base at each of the first and second positions.

[0263] At the second position, the magnetic attraction takes place between the first magnet 10220 of the base 10200 and a second magnet 10347 that is provided in the timer unit 10300. As seen in FIG. 21, the second magnet 10347 is located adjacent the rear 10302 of the timer unit 10300, in a recess 10352 formed on an inner surface of the rear casing 10331.

[0264] At the first position, the magnetic attraction takes place between a third magnet 10223, provided in the base 10200, and the second magnet 10347 of the tinier unit 10300. As seen in FIG. 23, the third magnet 10223 is located in a recess 10224 adjacent the first end 10204 of the base, the recess 10224 and the third magnet 10223 being covered by the rear panel 10222. Notably, due to the positioning of the magnetic switch 10346 towards the second end 10304 of the timer unit 10300, when the timer unit 10300 is in the first position there is no alignment between the third magnet 10223 and the magnetic switch 10346.

[0265] In this embodiment, the timer unit 10300 is releasably mounted to the base 10200. The arrangement is such that the timer unit 10300 can be removed from the base 10200 and replaced with a different timer unit. Replacement of the tinier unit 10300 may be necessary if its battery has insufficient charge or if it is desired to monitor a different predetermined time period. In some embodiments, the timer assembly may be provided as a kit that includes a plurality of timer units. The time units may be configured to monitor different predetermined time periods, e.g. 24 hours, 48 hours, 72 hours, etc.

[0266] To remove the timer unit 10300 from the base 10200, the timer unit 10300 is movable to a third position relative to the base. In this embodiment, when the timer unit 10300 is in the third position, as illustrated in FIGS. 19c and 20c, it is located between the first and second positions, roughly halfway between the first and second ends 10203, 10204 of the base 10200. When the timer unit 10300 is located in the third position, the tabs 10320, 10321 of the timer unit 10300 no longer abut against the raised regions 10212a, 10212b, 10213a, 10213b of the side surfaces 10205, 10206 of the base 10200, and instead line up with the gaps 10214, 10215 in the side surfaces 10205, 10206. Since the gaps 10214, 10215 are larger than the tabs 10320, 10321, the tabs 10320, 10321 can pass through the gaps 10214, 10215 enabling removal of the timer unit 10300 from the base 10200.

[0267] A base 10500 and a tinier unit 10600 of a timer assembly 10400 according to another embodiment of the present disclosure are illustrated in FIGS. 25a, 25b, 26a and 26b, respectively. In this embodiment, the tinier unit 10600 functions in a similar manner to the timer unit 10300 described above. However, the timer unit 10600 is configured to be rotatably mounted, rather than slidably mounted, to the base 10500. The base 10500 is a plate element having a circular, centrally located recess 10440 that is arranged to receive the timer unit 10600. The timer unit 10600 can be releasably held in the recess 10440 through magnetic interaction between magnets of the timer unit 10600 and the base 10500.

[0268] Following from this, the main difference between the timer assembly 10400 of the present embodiment and the timer assembly 10100 described above is the manner in which the timer unit 10600 is arranged to move between first and second positions of contact with the base 10500. In this embodiment, rather than there being linear movement of the timer unit 10600 between the first and second positions, the timer unit 10600 is arranged to rotate between the first and second positions. Again, the timer unit 10600 includes a magnetic switch 10546 and the base 10500 includes a first magnet 10520. When the timer unit 10600 is in the first position, as illustrated in FIG. 26a, the magnetic switch 10546 and the first magnet 10420 are misaligned and the magnetic switch 10546 is in the off state. When the timer unit 10600 is rotated to the second position as illustrated in FIG. 26b, e.g. by hand, the magnetic switch 10546 and the first magnet 10420 are aligned and the magnetic switch 10546 is in the on state, initiating monitoring of the predetermined time period.

[0269] In timer assemblies according to various preceding embodiments of the present disclosure, the monitoring of the predetermined time period is initiated by a user action related to a change in position of the timer unit relative to the base as discussed above. Monitoring of the predetermined time period may comprise counting up or counting down the predetermined time period using the timer.

[0270] The base can be fixed to a location that is easily accessible by a user and/or that provides a conspicuous location for observation or recognition by the user of the alert signal. In some embodiments, the base may include a fixing portion to fix the base to a support surface such as a surface of product in relation to which the predetermined time period is being monitored. For example, the base may be fixed to a portion of a cannula or endoscope. The fixing portion may include one or more adhesive pads 10260 positioned on the rear surface 10202 of the base 10200 as shown in FIG. 17b, for example. Additionally or alternatively, fixing portions that are used may include clips, screws, straps and/or hook and loop fasteners, for example.

[0271] Referring to FIG. 27, the fixing portion may comprise a flexible strap 10700 that extends from one or both ends 10203. 10204 of the base 10200. The flexible strap 10700 may form a loop that can extend around a tube, pipe, endoscope or other item to fix the timer assembly to that item. At least one end of the flexible strap 10700 may comprise a magnet 10701, 10702 that is attracted to one or more magnets 10220, 10223 located in the base 10200 as described above or to one or more further magnets in the base 10200. In some instances, the flexible strap 10700 may be passed over the front surface of the base in a manner that obstructs movement of the timer unit 10300 between the first and second positions, preventing inadvertent initiation or cessation of the monitoring of the predetermined time period. The strap may also, therefore, provide a form of locking mechanism for the timer assembly.

[0272] A label assembly 11100 according to an embodiment of the present disclosure is illustrated in FIGS. 28a and 28b. The label assembly 11100 is generally configured in the of a label tag that may be mounted to an article 11140, e.g. by being secured around and/or hung from the article.

[0273] The label assembly 11100 of FIG. 28a includes a body 11110 having a first face 11111 and a second face 11112. The first and second faces 11111, 11112 are located at opposite sides of the body 11110 and are connected together by side edges 11113. The first face 11111 and second face 11112 may provide two major outer surfaces of the body 11110. In this embodiment, the first and second faces 11111, 11112 are flat and the side edges 11113 are curved. In general, the body 11110 is a relatively flat component with the majority of its outer surface provided by the first and second faces 11111, 11112.

[0274] The label assembly 11100 includes a timer to monitor a predetermined time period and signalling apparatus to provide an alert signal on expiry of the predetermined time period, substantially in accordance with previous embodiments. In this regard, the label body 11110 may house an electronics unit e.g. of a type as described above with reference to FIG. 3.

[0275] Information relating to the time period that is monitored and/or the article relating to the time period may be printed and/or written on the first and/or second face of the body 11110.

[0276] The body 11110 defines a through-hole 11114, extending between the first face 11111 and the second face 11112 of the body.

[0277] The label assembly 11100 includes a mounting mechanism for mounting the label assembly 11100 to an article. The mounting mechanism includes a locking portion 11114 and an elongate portion 11130. The elongate portion 11130 has a first end 11131, a second end 11132 and a central region 11133 between the first and second ends 11131, 11132.

[0278] In this embodiment, the locking portion 11114 is provided in the through-hole 11131 of the body 11110 of the label assembly 11110. The first end 11131 and optionally also the central region 11133 of the elongate portion 11130 may be extended through the through-hole 11131 wherein the locking portion 1114 lockingly engages the elongate portion 11130, securing the elongate portion 11130 in a closed loop configuration.

[0279] In this embodiment, the elongate portion 11130 has one or more first teeth 11134 located at the first end 11131 and/or central region 11133 of the elongate portion 11130. The locking portion 11114 is configured to engage the first teeth to lockingly engage the elongate portion 11130. For example, the locking portion 11114 may comprise one or more second teeth that lockingly engage the first teeth. The locking portion may comprise a pawl comprising the one or more second teeth adapted to lockingly engage the first teeth. The mounting mechanism may therefore function in a similar manner to a cable tie.

[0280] By forming a closed loop, the elongate portion 111130 may be used to mount the assembly 11100 to an article, e.g. by hanging it from the article. While interlocking teeth/a pawl and tooth mechanism are described above to secure the closed loop, in alternative embodiments different locking features may be used to secure the closed loop.

[0281] As illustrated in FIGS. 28a and 28b, the through-hole 11131 may be located at a relatively central region of the label assembly 11100 where the assembly may be relatively strong and relatively protected from damage, e.g. in comparison to a periphery or side edges 11113 of the label body 11110. Nevertheless, in alternative embodiments, the through-hole 11131 may be provided elsewhere, e.g. in an extension of the label body 11110.

[0282] In accordance with previous embodiments, the label assembly 11100 includes an actuator 11126 that is removable, e.g. through an opening, to initiate monitoring of the time period. In this embodiment, the actuator is provided by a release element (tab 11126). The label assembly 11100 includes a sealing mechanism 11127 (see FIG. 28c), such as opposing resiliently flexible sealing or gasket elements 11127 held within the electronics unit housing, either side of the tab 11126 adjacent the opening, to seal the associated opening after removal of the release element 11126. This allows the label assembly 11100 to maintain a sealed configuration during use, protecting the electrical components of the device 11100 from contamination as a result of ingress of contaminants. When the label assembly 11100 is for medical use, the sealing mechanism may prevent body fluids entering the timer device. Such a sealing mechanism may be employed in other embodiments described herein, particularly where a removable actuator tab is employed.

[0283] The label assembly 11100 may provide a form of timing device or timing label, including a signalling apparatus, with an integrated cable tie. Additionally or alternatively, the label assembly 11100 may provide a security tag, security seal or cable tie tag with an integrated timing device and signalling apparatus.

[0284] Front and side views of a label 12100 according to another embodiment of the present disclosure are shown in FIGS. 29a and 29b. Like preceding embodiments, the label 12100 includes a timer to monitor a predetermined time period and a signalling apparatus that provides an alert signal on expiry of the predetermined time period.

[0285] The label 12100 has a substantially planar configuration, with substantially rectangular front and rear surfaces 12111, 12112, a first end edge 12113, a second end edge 12114, a first side edge 12115 and a second side edge 12116. The length direction of the label 12100 extends between the first and second end edges 12113, 12114 and the width direction of the label 12100 extends between the first and second side edges 12115, 12116.

[0286] In the length direction of the label 12100, the label 12100 includes a first label portion 12121, a second label portion 12122 and a third label portion 12123, the first label portion 12121 being located towards the first end 12113 of the label 12100, the second label portion 12122 being located towards the second end 12114 of the label 12100 and the third label portion 12123 being located between the first and second label portions 12121, 12122.

[0287] The first and second label portions 12121, 12122 are fixable together so that the label forms a closed loop. In this embodiment, at least one of the first and second label portions 12121, 12122 comprises a layer of adhesive 12133 covered by a releasable backing layer. The backing layer is releasable, e.g. by peeling, to expose the adhesive layer 12133.

[0288] The first and second label portions 12111, 12112 are configured to be permanently fixed together so that release of the closed loop may not be perthrmed without permanently damaging the label 12100. In general, the label 12100 is configured to take the form of a band or other generally ring-shaped item that can extend around a support surface or article. While the article may be a product such as a medical device, container or otherwise, in some embodiments, as shown in FIG. 30, it may be a body part such as a wrist 12199. In this regard the label 12100 may be a wearable device such as a wristband, leg band or similar, Thus, the label may be a wristband and the first, second and third label portions may be considered first, second and third wristband portions.

[0289] In this embodiment, the label is 12100 formed in part from a one-piece sheet of material that extends across the entire label 12100 between the end and side edges 12113, 12114, 12115, 12116. The one-piece sheet of material may be a plastic or paper material. For example, the one-piece sheet of material may comprise high-density polyethylene fibres, and may be a flashspun material, for example.

[0290] The label 12100 is substantially flat, except at a region where it includes a housing 12140, an electronics unit being located in the housing 12140. The housing 12140 and the electronics unit are formed in a similar or identical manner to the housing 1140 and electronics unit 1150 described above with reference to FIGS. 2a to 4. The electronics unit again comprises the timer to monitor the predetermined time period and the signalling apparatus that provides an alert signal on expiry of the predetermined time period. In this embodiment, the alert signal is provided by one or more LEDs that are visible through a window 12127 at the front surface of the third label portion 12123.

[0291] The label 12100 includes an actuator to initiate the monitoring of the predetermined time period by the timer. In this embodiment, the actuator is provided by a tab 12160. The tab 12160 has a proximal end that extends into the housing 12140 to interact with components of the electronics unit within the housing 12140 and an opposite distal end 12162 that is engageable by the user to pull the tab 12160 from the housing 12140. Pulling the tab 12160 can initiate the monitoring of the predetermined time period by allowing completion of an electrical circuit in the electronics unit in a similar manner to that described above with reference to the electronics unit 1150 of FIG. 3. A sealing mechanism may be employed adjacent an opening in the housing 12140 through which the tab 12160 is pulled, e.g. substantially as described above with reference to FIG. 28c.

[0292] In this embodiment, a first line of perforations 12124 extends between the first and second side edges 12115, 12116 of the label 12100 in the width direction of the label 12100, directly between the first and third label portions 12121, 12123, and a second line of perforations 12125 extends between the first and second side edges 12115, 12116 of the label 12100 in the width direction of the label 12100, directly between the second and third label portions 12122, 12123. The lines of perforations 12124, 12125 are provided in the one-piece sheet of material that extends across the label 12100 between the end and side edges 12113, 12114, 12115, 12116. The third label portion 12121 is therefore separable from the first and second label portion 12121, 12122 by a user tearing along the first and second lines of perforations 12124, 12125. The releasable connection between the third label portion 12123 and the first and/or second label portions 12121, 12122 may allow the closed loop to be opened without requiring release of the first label portion 12121 from the second portion 12122. The release of the connection between the third label portion 12123 and the first and/or second label portions 12121, 12122 may enable dismounting of the label 12100 from the support surface or article (e.g. from the wrist 12199 or otherwise). The release of the connection between the third label portion 12123 and the first and/or second label portions 12121, 12122 may be irreversible. For example, release by tearing of perforations or otherwise may permanently damage the label 12100, preventing re-use of the label 12100. Moreover, providing the option of removing the third label portion 12123 from the first and/or second label portions 12121, 12122 can also assist with waste disposal or recycling practices as described above.

[0293] In an alternative embodiment, as illustrated in FIGS. 31a and 31b, a label 12100 is provided that is otherwise identical to the label 12100 described above with reference to FIGS. 29a to 30, but which has only one line of perforations 12125, to allow the closed loop to be opened without requiring release of the first label portion 12121 from the second label portion 12122. In this embodiment the line of perforations 12125 is located between the second label portion 12122 and the third label portion 12123, although alternatively it might be located between the first label portion 12121 and the third label portion 12123.

[0294] Front and side views of a label 13100 according to another embodiment of the present disclosure are shown in FIGS. 32a and 32b. Like preceding embodiments, the label 13100 includes a timer to monitor a predetermined time period and a signalling apparatus that provides an alert signal on expiry of the predetermined time period.

[0295] The label 13100 has a substantially planar configuration, with substantially rectangular front and rear surfaces 13111, 13112, a first end edge 13113, a second end edge 13114, a first side edge 13115 and a second side edge 13116. The length direction of the label 13100 extends between the first and second end edges 13113, 13114 and the width direction of the label 13100 extends between the first and second side edges 13115, 13116.

[0296] In the length direction of the label 13111, the label 13100 includes a first label portion 13121 and a second label portion 13122, the first label portion 13121 being located towards the first end 13113 of the label 13100 and the second label 13122 portion being located towards the second end 13114 of the label 13100.

[0297] The second label portion 13122 provides a fixing portion of the label to fix the label to a support such as a transparent IV tube 13199 as illustrated in FIG. 33. The fixing portion 13122 is configured to fix the label 13100 to the support 13199 by extending around the support and fixing to the support 13199, fixing to itself and/or fixing to another surface of the label 13100 (e.g. by folding). In this embodiment, the fixing portion 13122 comprises a layer of adhesive 13133 covered by a releasable backing layer. The backing layer is releasable, e.g. by peeling, to expose the adhesive layer 13133.

[0298] The second/fixing portion of the label 13122 includes base layer of material that is that partially transparent, the layer of adhesive coating the base layer. The base layer and adhesive layer are both at least partially transparent or translucent. The transparency or translucency in the base layer may be provided through use of transparent or translucent polymer in the base layer, for example, and transparent or translucency in the adhesive may be provided through use of a clear adhesive

[0299] In general, the fixing portion 13122 of the label 13100 is at least partially transparent or translucent such that, when the label 13100 is fixed to the support 13199, the support 13199 is at least partially visible through the fixing portion.

[0300] By providing for at least partial visibility of the support 13199 through the fixing portion 13122, it may be possible to view more of the support 13199 than would otherwise be possible. For example, where the support 13199 is a transparent IV tube as shown in FIG. 33, it may be possible to check substantially the entire IV tube for patency. In simple terms, this means checking that the line is open and not blocked. By providing for at least partial visibility of the support 13199 through the fixing portion, it may be possible to check that a blockage is not present in the IV tube at the particular position where the label 13100 is fixed. Nevertheless, use of a the label 13100 having a transparent or translucent fixing portion is not limited to use with IV tubes only. The label 13100 may be used in a variety of situations where it is desirable to reduce obscuring of an underlying label support.

[0301] In contrast to the second/fixing 13122 portion of the label 13100, the first label portion 13121 of the label 13100 may or may not comprise transparent or translucent material

[0302] In this embodiment, the label 13100 is substantially flat, except at a region where it includes a housing 13140, an electronics unit being located in the housing 13140. The housing 13140 and the electronics unit are formed in a similar or identical manner to the housing 1140 and electronics unit 1150 described above with reference to FIGS. 2a to 4. The electronics unit again comprises the timer to monitor the predetermined time period and the signalling apparatus that provides an alert signal on expiry of the predetermined time period. In this embodiment, the alert signal is provided by one or more LEDs that are visible through a window 13127 at the front surface of the first label portion 13121.

[0303] The label 13100 includes an actuator to initiate the monitoring of the predetermined time period by the timer. In this embodiment, the actuator is provided by a tab 13160. The tab 13160 has a proximal end that extends into the housing 13140 to interact with components of the electronics unit within the housing 13140 and an opposite distal end 13162 that is engageable by the user to pull the tab 13160 from the housing 13140. Pulling the tab 13160 can initiate the monitoring of the predetermined time period by allowing completion of an electrical circuit in the electronics unit in a similar manner to that described above with reference to the electronics unit 1150 of FIG. 3. A sealing mechanism may be employed adjacent an opening in the housing 13140 through which the tab 13160 is pulled, e.g. substantially as described above with reference to FIG. 28c.

[0304] In this embodiment, a line of perforations 13124 extends between the first and second side edges 13115, 13116 of the label 13100 in the width direction of the label 13100, directly between the first and second label portions 13121, 13122. The second label portion (fixing portion) 13122 is therefore separable from the first label portion 13121 by a user tearing along the lines of perforations 13124. The releasable connection between the first and second label portions 13121, 13122 can allow the first portion 13121 to be removed or disconnected from a support surface to which the label is fixed (e.g. IV tube 13199 or otherwise) while the second portion 13122 remains fixed to that support surface. Moreover, providing the option of removing the second label portion 13122 from the first label portion 13121 can also assist with waste disposal or recycling practices as described above.

[0305] Front, rear and side views of a label 14100 according to another embodiment of the present disclosure are shown in FIGS. 34a to 35b. Like preceding embodiments, the label 14100 includes a timer to monitor a predetermined time period and a signalling apparatus that provides an alert signal on expiry of the predetermined time period.

[0306] The label 14100 includes a housing 14140 comprising opposing front and rear surfaces 14111, 14112, and a plurality of sides surfaces that extend between the front and rear surfaces and define a peripheral edge of the housing. The side surfaces include a first end surface 14113, a second end surface 14114, a first side surface 14115 and a second side surface 14116. An electronics unit is located in the housing 14140, the electronics unit being formed in a similar or identical manner to the electronics unit 1150 described above with reference to FIGS. 2a to 4. The electronics unit again comprises the timer to monitor the predetermined time period and the signalling apparatus that provides an alert signal on expiry of the predetermined time period, in this embodiment, the alert signal is provided by one or more LEDs that are visible through a window 14127 at the front surface of the housing 14100.

[0307] The label 14100 includes a fixing portion 14122 that is configured to fix the label 14100 to a support surface. In this embodiment, the fixing portion 14122 comprises a layer of adhesive located over the rear surface 14112 of the label 14100, the adhesive layer being covered by a releasable backing layer. The backing layer is releasable, e.g. by peeling, to expose the adhesive layer.

[0308] The housing 14140 of the label 14100 includes a groove 14117 that extends around the entire peripheral edge of the housing 14140. The groove 14117 provides for a finger grip, allowing a user to grasp the label 14100 using their fingers, e.g. in order to manipulate the label 14100 when fixing the label 14100 to a support surface or when removing the label 14100 from a support surface. In alterative embodiments, the groove may extend only partially around the peripheral edge of the housing. For example, the groove may be located at least partially along the first side surface 14115 and the second side surface 14116 only.

[0309] The label 14100 includes an actuator to initiate the monitoring of the predetermined time period by the timer. In this embodiment, the actuator is provided by a tab 14160. The tab 14160 has a proximal end that extends into the housing 14140, via a slot 14161 in the housing 14140, to interact with components of the electronics unit within the housing 14140. An opposite distal end 14162 of the tab 14160 is engageable by the user to pull the tab 14160 from the housing 14140. Pulling the tab 14160 can initiate the monitoring of the predetermined time period by allowing completion of an electrical circuit in the electronics unit in a similar manner to that described above with reference to the electronics unit 1150 of FIG. 3. In this embodiment, the slot 14161 is positioned in the groove 14117, and substantially the most recessed point of the groove 14117. Accordingly, the slot 14161 is located in a generally recessed position on the outer surface of the housing 14140. This provides for protection of the slot 14161 and reduces the likelihood of damage of the slot 14161 or ingress of contaminants through the slot 14161 into the housing 14160.
