[0099] Similar elements in the different Figures have corresponding reference numbers, those of a particular embodiment differing by 1000 from those of other embodiments.

[0100] A monitoring device 100 according to an embodiment of the invention will now be described with reference to FIGS. 1, 2 and 3. The monitoring device 100 comprises a casing 102 enclosing a radio receiver 104 (see FIGS. 2 and 3) coupled to a dipole antenna 106 (and/or other external/internal antenna) for receiving usage information from a metering system, and having an illuminated display area 108, and a digital display 110, the latter being, in this instance an LCD screen, for example a 64128 resolution LCD display, for displaying alphanumeric 112 and/or graphical information 114 in one or more modes. The monitoring device 100 also has three multifunction and user-actuated pushbuttons 116 for turning the device on and off and for selecting display modes for displaying different sets of information as will be described in more detail with reference to FIGS. 5A to 5O respectively.

[0101] The casing 102 comprises a molded plastic casing suitable for wall mounting or table-top display.

[0102] In this embodiment the illuminated display 108 comprises a frosted, arcuate, generally linear obliquely-angled outermost end surface of a light guide 118 extending from a top of the casing 102. The display surface 108 faces towards the rear of the casing 102 but reflects light impinging upon from the interior end of the light guide 118 so that it emanates forwardly of the casing 102. Parts of the arcuate display area 108 may be selectively and sequentially illuminated by light launched into the light guide from an array of light sources, specifically LEDs 120 (see FIGS. 2 and 3) within the casing 102. Thus, the light guide 118 constitutes optical coupling means for directing light from the array of LEDs 120 to illuminate selected parts of the arcuate display area 108.

[0103] As shown in FIGS. 2 and 3, the array comprises six bi-colour LEDs 120/1 to 120/6 provided on an internal circuit board 122 (not visible in FIG. 1).

[0104] At its interior end portion, the light guide 118 has two curved tongue portions 118 a and 118 b which protrude through rectangular holes 124 a and 124 b, respectively, so that endmost surfaces 126 a and 126 b are in close proximity to the LEDs 120 and light therefrom couples into the lightguide 118. Generally, each LED will illuminate a corresponding segment or part of the arcuate surface 108. It will be appreciated, however, that the transitions between adjacent segments, when illuminated, will not be sharply defined due to specular scattering and diffusion effects.

[0105] FIG. 4 shows a schematic block diagram of the components inside the monitoring device shown in FIGS. 1, 2 and 3. Receiver 104, actually part of a transceiver, receives information from a corresponding transmitter of a smart metering system and conveys the information to a microcontroller 130, which is powered as is conventional from a power supply 132, with an optional battery 134. Also provided is an interface unit 136 which is connected to the USB port 138 for a standard USB network connection and/or to a specialized connection port 138. The power supply 132 is shown with a port 140 (optional) for connection to an external source to charge the battery (if rechargeable).

[0106] The information includes at least one usage metric related to a present rate of consumption. The receiver may also receive from the smart meter data such as time of use, current rate period and associated tariff, energy usage in energy and/or currency units, and cumulative usage or usage history, though, in preferred embodiments, such additional data is provided within the monitoring device itself; time of day from an internal clock, other data previously stored in a memory device, and so on, especially if the monitoring device is able to communicate with the utility company and receive updates.

[0107] The receiver may be combined with a transmitter, i.e. in a transceiver, enabling it to exchange information with a complementary transceiver at the meter, the utility or utility related transceivers (fixed or mobile).

[0108] The multicoloured LED bank or array 120 for illuminating the display 108 (not shown in FIG. 3) is linked to the microcontroller 130 via LED control unit 142 which will be described in more detail below. The second display, in the form of LCD screen 110, has a built in controller (not shown) which communicates with the microcontroller 130, and there is a user interface 144 which couples the pushbuttons 116 (including a power on/off pushbutton) to the microcontroller 130 for selecting a display mode for the LCD display 110. Other elements linked to the microcontroller 130 include a manual reset 146, an audible indicator or alerter module 148 and an extended memory module 150.

[0109] Referring to FIG. 4, drive current for the bi-colour LEDs 120 is supplied by LED control circuitry 142 under the control of microcontroller 130. Such a bi-colour LED usually comprises a group of two closely-spaced LED elements co-packaged, for emitting red and green light, respectively. The microcontroller 130 will energize the R, G LEDs individually or in combination to obtain the colour to be emitted. For example, red may indicate critical peak tariff, orange indicate peak tariff, yellow mid-peak tariff and green low-peak tariff. In addition, the microcontroller 130 will energize the bicolour LEDs selectively so as to illuminate different parts of display surface 108 in a sequence or pattern. Thus, the microcontroller 130 may cause the individual bi-colour LEDs to be energized so that the coloured light will move along the arcuate display area 106 in a manner indicative of the usage metric received from or calculated from the meter, i.e., consumption rate.

[0110] In some cases, the information from the meter may comprise only a measure of the aggregate consumption of the electrical power being drawn, in which case the microcontroller 130 will use its internal clock to determine consumption rate. The microcontroller 130 will access internal memory and/or extended memory 150 to obtain other data, such as pricing tiers or tariff rates.

[0111] Pricing tiers may be determined temporally, e.g., cost of a present unit is determined by the time/day/month/year it is consumed, or volumetrically, e.g., cost of a present unit is determined according to how many units have been consumed previously (since a certain datum). In the latter case, the tiers might be defined by a series of threshold levels at each of which the cost-per-unit increased.

[0112] It is envisaged that the illuminated display could also indicate an impending transition to a different tier, for example by illuminating a separate LED and display area or by merging colours (fade out-fade in).

[0113] So, for example, during an off peak rate period, the display colour would be green, and each of the bi-colour LEDs 120 would be energized to emit that colour (specifically by activating the green LED in its group) and illuminate a corresponding area of the display 108. At a consumption rate, the LEDs 120 would be energized in sequence so that discrete areas or segments of display area 108 would be illuminated in turn, effectively causing an illuminated green segment to move slowly along the length of the arcuate display 108. As the consumption rate increased, the controller 130 would increase the sequence rate and thereby increase the speed at which the green segment travelled along the arcuate path. The movement of the illumination pattern visually simulates rotation of a disc of a conventional electricity meter at a speed indicative of consumption rate.

[0114] As the rate period changes from mid-peak to peak tariff, the controller 130 will cause the LEDs to emit orange and then red light. The controller 130 may also turn the LEDs 120 on and off to cause the display light to flash a particular colour and thereby indicate a critical peak tariff period. Of course, some other modulation pattern could be used to the same end.

[0115] Audible indicator 148 may be used to sound audible alerts. An insistent stoppable alarm may be associated with a critical peak, whereas a softer alarm may indicate a countdown to a next rate period.

[0116] The illuminated display could be arranged to indicate elapsed time with respect to a rate period, e.g., indicating whether current time is near a beginning or end of a particular time of use rate period. For example, illuminating an area extending along three-quarters of the length of the arcuate surface 108 might indicate that the present time of day is three-quarters of the way through the rate period associated with the colour displayed. (See FIGS. 17A to 17F).

[0117] As is well known, the human eye responds quickly to perceived movement, so, beneficially, a change in colour and a moving pattern of light are effective in alerting consumers to a change in consumption rate and cost in such a way that the information can be assimilated quickly, at a glance. This is especially so when the moving pattern simulates linear or rotational motion. In catching attention, scanning of the illumination across the display at a defined traverse speed may be preferred to a stationary blinking or flashing light, which may be seen as intrusive or irritating.

[0118] The second, digital display, specifically LCD screen 110, is used for displaying more detailed information of these and/or other metrics or parameters relating to current or cumulative usage. Examples include graphical display of hourly usage, e.g. for the last 24 hours in $ or kWh; daily usage for the last 30 rolling days in $ or kWh; totals for each individual Time of Use (TOU) period combined in kWh and $; instantaneous or average demand consumption, showing power currently being used.

[0119] The actual data displayed may be selected using one or more of the pushbuttons 116. FIGS. 5A to 5O illustrate examples of data displayed by the second display 110, as follows: [0120] FIG. 5AAbsolute kWh reading from total and three tiers from meter tables; [0121] FIG. 5BAnalogue Speedometer showing current consumption, bars showing monthly total for 3 standard tiers and critical peak; A short term total (day/week) and total; [0122] FIG. 5CAnalogue Speedometer showing current consumption, bars showing hourly total for one day, A short term (day/week) and total; [0123] FIG. 5DAnalogue Speedometer showing current consumption, bars showing daily total for the month, A short term (day/week) and total; [0124] FIG. 5EConsumption in cost tiers represented by $..$$$$ with a base amount; [0125] FIG. 5FCost per tier represented by $..$$$$ with a base amount; [0126] FIG. 5GBars depicting daily total, day, in dollars/day & total $$; [0127] FIG. 5HBars depicting daily total day, in kWh/day & total kWh; [0128] FIG. 5IConsumption in cost tiers represented by $.$$$$ with no base amount; [0129] FIG. 5JCurrent (instantaneous) consumption depicted using IOOW light bulb graphics icons; [0130] FIG. 5KCurrent (instantaneous) consumption in kW; [0131] FIG. 5LConsumption total for a user-selected time frame with average consumption and a sub-interval; [0132] FIG. 5MConsumption total for a user-selected time in kWh and dollars; [0133] FIG. 5NBars depicting hourly total, for one day, in dollars per hour and total dollars; and [0134] FIG. 5OBars depicting hourly total, for one day, in kWh per hour and total kWh.

[0135] Because the second display 110 is digital, it is a very simple matter to change the data which can be displayed, the different display screens being selected, as mentioned, by means of one or more of the pushbuttons 116.

[0136] Many consumers do not fully appreciate the implications of energy consumption rates when expressed numerically, so the data display shown in FIG. 5J is particularly advantageous because it depicts the consumption rate as a equivalent number of light bulbs of a given (common) wattage, for example 6 OW or 10 OW. Most consumers will appreciate the significance of a large number of these light bulb units of energy being displayed during a critical, high tariff period and be motivated to check for appliances which can be turned off, at least temporarily.

[0137] Data port 138, for receiving a USB or other data connector, such as a network connector (not shown), and connected to data interface unit 136, enables data to be outputted, under the control of controller 130, perhaps for analysis or storage, to a personal computer or personal digital assistant. Although a USB port is indicated, data interface 136 might use one or more other kinds of data transmission mode, such as infrared, Bluetooth, and so on, or even connect to a network (Ethernet, Internet) to transmit data to the utility or elsewhere. It might also be capable of downloading data to update data, such as tariff rates, stored in the memory 150. Moreover, it may also be used to connect a power supply, with appropriate modification of the connections within the monitoring device, For Power Line Communication (PLC) type meter systems, the data interface 136 also has a serial input port 138.

[0138] It should be noted that the receiver 104 of the above-described monitoring device could be part of a transceiver, the transmitter part being used to communicate with the utility meter and/or the utility company.

[0139] As shown in broken lines in FIG. 4, a typical smart meter 152 has its own receiver (usually part of a transceiver) 154 which can transmit usage data to the utility company and receive software and/or data updates. In many cases, the receiver 104 of the monitoring unit 100 will be able to communicate with the transceiver 154, any proprietary transmission protocol being licensed as necessary. The receiver 104 may be programmable to adapt it for use with different types of smart meter. Alternatively, several interchangeable dedicated receiver/transceiver modules 104 may be provided, each for a particular type of meter transceiver, and the appropriate one selected and installed onto the circuit board 122.

[0140] FIG. 6 is a simple flowchart depicting the basic operation of the microcontroller 130 as it controls the acquisition of the data for the different usage metrics, either via the receiver 104, from look-up tables in the memory 150 or even by communicating with the utility, computing the information to be displayed, and then controlling the two displays 108 and 110 to display the data. It should be noted that, depending upon the model, the meter transceiver 154 may transmit either or both of the present consumption rate and the present aggregate consumption; in the latter case, the microcontroller 130 will use its own internal clock to convert successive aggregate consumption readings into a consumption rate.

[0141] Although the above-described embodiment is designed to communicate with a smart meter having its own transmitter (transceiver), the monitoring device 100 may be used with a conventional electricity meter by installing a suitable transmitter/transceiver adapter at the meter. Such an adapter might take the form of an external sensor clamped to the meter case and having a sensor for detecting a mark on the usual spinning wheel, as disclosed in the afore-mentioned US published patent application No. 2005/0222784US, but that is not preferred because it can miscount and be tampered with too easily; utilities prefer that users do not interfere with the meter; cold or heat can cause the clamp to slip and the sensor to lose alignment; a nick in the plastic housing of the meter by the metal clamp or tool used to tighten it can start a stress fracture in the plastic which will render the seal to weather elements void; and it requires a separate battery.

[0142] It is preferable to install a transmitter/transceiver adapter between the conventional electricity meter and the meter receptacle into which it is plugged and monitor consumption directly. Such a transceiver adapter 156 is illustrated in FIGS. 7 and 8 and comprises a generally circular, base in the form of a disc 158 having a circumference similar to that of the electricity meter and receptacle. Four connectors 160, equally-spaced from each other in a rectangular pattern extend through the disc 158 (a standard form IS/2S Meter base). As shown in FIG. 7, each connector 160 has a prong portion 160 a protruding from the rear of the disc 158 (i.e., which faces the receptacle when installed) and a bifurcated portion 160 b protruding from the front of disc 158 to receive a corresponding prong (not shown) of the meter contact, (supply or load as the case may be). Two of the connectors 160, specifically their prong portions 160A, are each surrounded by a coil 162 which constitutes a secondary winding of a current transformer (the connector 160 being the primary winding).

[0143] The pair of current transformers output currents proportional to the current flowing in the line connectors 160, i.e., through the meter. An AC/DC power module 164 has a first stage 164 which extracts power from the supply contacts and converts it to a relatively high DC voltage and a second stage 164 which reduces the DC voltage and uses it to supply a microcontroller 166, LAN and WAN data communications interfaces 168 and 170, respectively, external meter data interface 172, extended memory 174 and a load monitoring circuit 176. Whether the power supply 164 uses the supply contacts or the load contacts will depend upon local regulations which, in some cases, require power for the meter to be derived pre-meter and in other cases allow power to be derived post-meter.

[0144] The load monitoring circuit 176 is connected to the current transformer coils 162 and monitors both present voltage and present current in order to calculate a present aggregate power level which is converted to digital form (with a specialty hi-speed A to D) and supplied to the microcontroller 166. The latter conveys this information to the LAN interface 168 for transmission to the monitoring unit 100 via the dipole antenna.

[0145] The transceiver adapter 156 can be used not only to transmit the usage metric information to the monitoring device 100, but also to a central repository or central database, such as at a utility or elsewhere by way of data interface 172 or WAN interface 170 with WAN dipole antenna 180, as appropriate. As indicated in boxes 168 and 170 of FIG. 9, any of a variety of data communications modes may be employed, such as GSM Cellular data (GPRS) modem WAN; WiFi 802.11 b modem (2.4 GHz LAN); and/or Low Earth Orbit (LEO) ORBCOMM* satellites. Meter information may be sent in short bursts once a day to a ground relay station and from there via the Internet to a central server. Thus, the WAN transceiver 170 may have the following features: GSM communication, where available; WiFi in controlled corridors; LEO VHF 138-150 MHz band provides long-range communications even in challenging environments; CDMA communications; licensed SCADA Band (450 MHz typical) communication; simple installationfits onto new or existing form 2S meter socket; and low power consumption <0.6 watts.

[0146] It is also envisaged that the monitoring device and/or the transceiver adapter 156 could supply the usage metric information to a personal computer in the building, or to a portable computer or to a Blackberry (trademark) or other similar hand-held device. The supplemental usage metric transmission could be displayed in such a way that it depicts the monitoring device 100. Thus, FIGS. 21A and 21B illustrate a personal computer displaying an image of the monitoring device with its illuminated display and data corresponding to its digital display based on meter readings communicated using the transceiver 104 of FIGS. 1 to 4 or, if preferred, the data interface 136. Likewise, FIGS. 21C and 21D illustrate a similar display on a Blackberry (Trademark) or other similar such device. In the latter case, the transmission might be routed via a server type system to create the graphics. Such transmission to a user device at a remote location could warn a parent, for example, of critical usage by other members of the family, for example children.

[0147] The invention embraces monitoring units having other configurations of illuminated display and, possibly, no second, digital display 110. Since a LCD display tends to be an expensive component, omitting it may provide an alternative lower cost option which still provides effective visual alerting when more detailed information is not required. Examples of these alternative embodiments of monitoring device will now be described with reference to FIGS. 10A to 20.

[0148] Thus, FIG. 10A shows a monitoring device according to a second embodiment, which has an illuminated display, in the form of a straight, elongate window or lens 208 near the top of the casing 202. If desired, the window or lens 208 may be translucent or frosted to provide diffusion. The corresponding printed circuit board shown in FIG. 10B has a straight row of LEDs 220 which, when the board is installed will be aligned with window 208.

[0149] The single row of LEDs may be selected and driven to illuminate the window/lens 208 with one of red, orange/yellow and green light dependent on rate period, the illumination being scanned linearly across the window at a traverse rate dependent on, and indicative of, a rate of consumption; for example, by sequentially illuminating the linear array of LEDs.

[0150] FIGS. 11A and 11B illustrate an embodiment in which the casing 302 is slotted to accommodate a display area comprising three straight elongate windows 308 a, 308 b, 308 c in the casing for displaying, respectively, red, orange/yellow and green illumination provided by straight three rows of LEDs 320 a, 320 b, 330 c, respectively, each row aligned with a respective one of the windows.

[0151] FIGS. 12A and 12B illustrate a monitoring device similar to that shown in FIGS. 10A and 10B but having a casing 402 in which the window or lens 408 is curved and the row of LEDs 420 is curved so as to align therewith.

[0152] FIGS. 13A and 13B illustrate yet another embodiment, similar to the previous embodiment in which the casing 502 has a set of 3 linear windows 508 a, 508 b, 508 c, but they are arcuate instead of straight and the corresponding LED array comprises three arcuate rows of LEDs, each aligned with a respective one of the windows.

[0153] Each of the monitoring devices shown in FIGS. 10A to 13B will have a LED controller similar to controller 142 of the first embodiment, but adapted to suit the particular array of LEDs. Likewise the programming of the microcontroller 130 would be modified as required.

[0154] Each of the above-described embodiments having alternative display configurations has a circuit board carrying one array of LEDs arranged according to the configuration of the corresponding display, i.e., a different display will require a different circuit board. It is envisaged, however, that a single circuit board could be provided with several different arrays of LEDs each corresponding to a respective one of several different available displays. The LED controller and microcontroller then would be set to illuminate the appropriate one of the arrays according to the display type of the casing in which the circuit board is installed. Such a multipurpose printed circuit board is illustrated in FIG. 22 and has several arrays of LEDs each corresponding to a respective one of the LED arrays shown in FIGS. 10B, 11 B, 12B and 13B enabling the same circuit board to be used with any one of the casings of FIGS. 10A, 11A, 12A and 13A simply by selecting the appropriate one of the LED arrays.

[0155] It should also be noted that, although the above-described embodiment uses bi-colour LEDs, the LED array may comprise, say, 6 to 10 individual coloured LEDs or groups of LEDs, arranged as previously described. Typical configurations may include bi-colour arrangements of red and green LEDs or tri-colour arrangements of red, green and blue (RGB) LEDs. Multiple LEDs may be pulsed simultaneously using different duty cycles and at different frequencies to provide a variety of colours, including white. In the latter, intensity and colour is controlled by varying pulse width modulation of the RGB LEDs which may be turned on and off in various sequences and at varying frequencies to provide different patterns of illumination in a selected colour to be displayed.

[0156] In the embodiments of FIGS. 10A to 13B, the light guide 118 (FIG. 1) is omitted and the illuminated display comprises an area of the window or set of windows or lenses (possibly of translucent material), through which the light from the array of LEDS passes through the casing without need for other optical components. Notwithstanding that, whether the display area comprises a translucent or frosted material or note, it may be illuminated indirectly using known optical arrangement of reflectors, prisms, light guides, optical fibers and the like.

[0157] The embodiment shown in FIG. 1 uses a single light guide 118 having a display area in the form of an oblique surface 108. FIG. 14 shows a similar monitoring device 600 display comprising three similar light guides 618 a, 618 b, 618 c of increasing radii sandwiched together so that the respective oblique display surfaces 608 a, 608 b, 608 c form a stepped display. Each light guide is coupled to a row of LEDs of a different colour to the other so that three parallel bands of coloured light can be displayed in rainbow fashion. With this arrangement, the different colours could be turned on in succession to reflect changes in the tier or tariff while the illuminated area of each band could be scanned to indicate consumption rate. It will be appreciated that, instead of three light guides in parallel, the three oblique display surface could be formed by stepping the surface of a single, thicker light guide. Various other combinations could be conceived.

[0158] It will be appreciated that numerous arrangements for the configuration of the illuminated display are possible and the afore-mentioned examples are not intended to be limiting.

[0159] FIGS. 15(A) to 20 illustrate options for illumination of the different kinds of illuminated displays 108 and 608.

[0160] Thus, FIGS. 15A to 15C illustrate illumination of the three oblique surfaces of the light guides 608 being illuminated in sequence, beginning with the radially innermost surface 608 a. The same sequence could be applied to the monitoring devices 302 and 502 which have three windows rather than three light guide surfaces.

[0161] FIGS. 16A to 16F illustrate illumination of different parts or segments of the single light guide surface 108 to show a bead of light moving from one (left) end of the surface 108 to the other (right). If desired, the bead of light could be caused to travel to and fro, whether to continue showing consumption or, perhaps, to show that the monitoring device is in a different mode of operation, for example an initialization phase. The single window version of FIGS. 10A and 12A could be illuminated in a similar manner.

[0162] FIGS. 17 a to 17F correspond to FIGS. 16(a) to 16(f) but depict successive parts of the single display being illuminated progressively to cause the length of the coloured portion of the display to increase from one (left) end towards the other (right) end.

[0163] FIGS. 18A to 18C illustrate schematically illumination of different parts of the single display area 108 of the monitoring device of FIG. 1 to produce the effect of bubbling, i.e., similar to the illumination of FIGS. 16A to 16 c producing a bead of light travelling from left to right and FIGS. 16F to 16D producing a bead of light travelling from right to left. The beads could either disappear when they meet in the middle, to start again at their respective ends, cross over; the cycle then repeating.

[0164] It is also envisaged that the beads could create certain patterns. For example,

[0165] FIG. 19 illustrates simultaneous illumination of two different parts of the single display area 108 of the monitoring device of FIG. 1 spaced apart by a non-illuminated part of the arcuate display area 108, the two parts traversing the display area in a manner similar to that described with reference to FIG. 16.

[0166] Moreover, it would be possible to illuminate adjacent parts of the display area 108 with different colours, as illustrated in FIG. 20. The beads could be two or more beads with different ones of the plurality of colourswith or without separation using the motion or filling of FIG. 15 or 16.

[0167] FIGS. 21A, 21B, 21C and 21D illustrate the use of a computer or handheld device to display an image representing a monitoring device of FIG. 1; and data that would appear on the devices screen.

[0168] FIG. 22 illustrates schematically a printed circuit board that can be used with several different illuminated displays.

[0169] Beneficially the monitoring device may support TOU or non-TOU rate periods; Automated Meter Reading (AMR) which may be simplex receiving or two way or Advanced Meter Infrastructure (AMI) which is two way and may support data exchange beyond meter billing data.

[0170] Although each of the above-described monitoring devices has an internal dipole antenna, it could have an external antenna, either in addition or as an alternative. Where the monitoring device comprises a transceiver, it may also act to relay data to other devices, and may comprise a translator to translate data between different data formats and transmission protocols, facilitating operation in a number of modalities. The monitoring device may also receive signals from one or a plurality of other smart metering devices or systems, such as electricity, gas and water, and other services. The monitoring device may comprise more than one radio, or other hardware, software or firmware to facilitate data exchange between more than one system (different utilities or different types of devices) which may use different radio frequencies or protocols.

[0171] Where a plurality of devices are networked, updates may be obtained automatically through an Internet connection, USB, or utility broadcast, e.g., by ZigBee.

[0172] Where two-way messaging is provided, optional functions such as intelligent thermostat control may be provided, or messaging may be received from a utility company, which may include alarms to prompt the consumer to shut off appliances, such as an air conditioners during a critical period, or alerts warning of an imminent critical peak or other threshold conditions. Such alerts or alarms could be notified to the consumer by modulating the illuminated display and/or by means of the audible indicator, as previously mentioned.

[0173] A home may have a single meter with a transceiver which may be monitored in two or more locationstypically kitchen, laundry room and front door. Additionally, a PCT thermostat may communicate with the In-Home Display to duplicate a sub-set of use information, or to allow the In-Home Display to control the thermostat.

[0174] Some embodiments of the invention may be represented as a software application stored in a machine-readable medium (also referred to as a computer-readable medium, a processor-readable medium, or a computer usable medium having a computer readable program code embodied therein). The machine-readable medium may be any suitable tangible medium, including magnetic, optical, or electrical storage medium including a diskette, compact disk read only memory (CD-ROM), memory device (volatile or non-volatile), or similar storage mechanism.

[0175] The machine-readable medium may contain various sets of instructions, code sequences, configuration information, or other data, which, when executed, cause a processor to perform steps in a method according to an embodiment of the invention. Those of ordinary skill in the art will appreciate that other instructions and operations necessary to implement the described invention may also be stored on the machine-readable medium. Software running from the machine readable medium may interface with circuitry to perform the described tasks. This software embodiment will likely simulate the look and feel as well as function of the physical product. The software which, when loaded into a computer or handheld device, creates the two displays on screen and causes the control means (processor etc. inside the computer) to control the display to provide the two colours and the motion.

[0176] Therefore, where the monitoring device comprises a transceiver capable of transmitting usage data or information to another device, this information may be used to provide control of smart appliances, a thermostat, or other controller, or to relay information to a consumer, e.g. to a remote or hand held device to enable user intervention, for example where power consumption exceeds a threshold.

[0177] Furthermore, other embodiments of in-home monitoring may be implemented in software, using a display, e.g. on a computer, graphical display or handheld device to provide a graphical indicator and an illuminated display showing a colour dependent on a cost of consumption and motion dependent on a rate of consumption.

[0178] It is envisaged that the LCD display could have a touch-sensitive screen and the push buttons 116 integrated into the LCD display in known manner.

[0179] The monitoring device, system and method according to embodiments of the invention provide improved or alternative ways for consumers to monitor usage of utilities, in particular, the illuminated display which uses colour to indicate a present cost or rate period, and simulated movement which indicates a present rate of consumption provides at a glance monitoring of rate of consumption and present unit cost.

[0180] Scanning, sweeping motion or other motion (linear or rotational) of illumination of the display advantageously tends to catch the attention visually, without being as intrusive as flashing or blinking lights. Beneficially, a digital display may be offered with both the illuminated display and a digital display to provide more detailed alphanumeric or graphical information. Audible alerts may optionally be provided. Improved devices for in-home monitoring and display of real time usage assists in encouraging consumers to manage consumption and cost. Devices may be offered to be compatible with a number of wired and wireless networking protocols, and preferably provide a digital display for providing more detail information, and a network connection for transferring data to a repository or other device for analysis. Lower cost and simpler displays, perhaps with an illuminated display only, may be deployed at multiple locations in the home, and conveniently networked directly or through the main monitoring device to receive information from a smart meter. They might also be networked through a consumer's home wireless network.

[0181] Each of the plurality of colours may represent a respective one of a corresponding plurality of different levels of funds available and the controller may cause the light source to illuminate different parts of the display sequentially at a rate indicative of present rate of consumption.

[0182] A monitoring device, system and method is provided for in-home or on-premises monitoring of the usage of utilities, such as electricity and other services. The monitoring device receives information from a smart metering system or transceiver, and displays current usage through an illuminated display, which displays a colour indicative of the current cost of consumption, and controls illumination of the display to simulate scanning, movement or rotation across the display at a traverse rate indicative of a rate of consumption or another usage parameter. The display therefore provides a consumer with immediate at a glance visual information on current usage. Optionally a digital display screen provides more detailed alphanumeric and graphical information, through a number of selectable display modes. Beneficially one or more devices may be networked, and interface directly or indirectly with a transceiver of a smart metering system, or a retrofit transceiver for a conventional meter. While particularly suited to electricity monitoring, monitoring of other utilities and services may alternatively or additionally be provided. The system may be used with a wired network or wirelessly networked by one of a number of standard wireless and mesh network communication protocols.

[0183] Other advantageous display features may include: TOU period status, time to next period; comparable periods, monthly; prediction of kWh and $ to end of current period; voltage, high and low; KW peak draw; clock-updated by meter, 12 or 24 hour mode; connectivity to computer and or thermostat; ability to display water and gas readings in a more simplified form; messaging, Amber Alert, etc. from utility; two-way communication enabling the consumer to acknowledge receipt of a message, e.g. advising of a shut down time for a later period. Some of these features may require specific external network functionality. Others can be provided using wired communications or ZigBee. As more or different features/interpretations are available, the monitor can adapt using software, hardware and/or firmware updates.

[0184] Although embodiments of the invention have been described in detail with respect to monitoring of usage of electricity, other embodiments of monitoring devices, systems and methods may be applicable to monitoring of other utilities, or services which may or may not be metered. Other embodiments may also be applicable to providing consumers with devices for visually monitoring usage of services such as bandwidth or other chargeable communications services which are subject to time of use dependent rates (i.e. weekday, weeknight or weekend or evening rates) or surcharges based on usage exceeding a threshold number of minutes or kWh.

[0185] Within the embodiments of the invention presented supra in respect of FIGS. 1 to 22 the measurement or quantification of the utility and the utility are described and depicted with respect to public utilities such as water, electricity, and gas or other goodsservices that are metered. However, it would be evident that the visual cues presented to the user within the embodiments of the invention described supra in respect of public utilities and/or metered goodsservices may be applied to other utilities. Further, a visual cue may relate to two or more measurements and/or quantifications of the same utility or different utilities. For example, an arrow may have the visual cue characteristics of direction, size, and colour associated with a utility or multiple utilities. Within a first scenario, considering an arrow visual cue, then direction (up/down) relates to a time dependent rate of a utility, size relates to the current magnitude of the utility, and colour relates to a current cost of the utility. Within another scenario, considering an arrow visual cue, then direction relates to net consumption or generation, size relates to current rate, and colour relates to cost. Optionally, the visual cue may be a semi-circle wherein in the left side of the display it relates to net consumption of the utility, in the right side of the display it relates to net generation, size relates to rate of consumption/generation and colour relates to cost/income of the consumption/generation. Alternatively, a circle may have a size determined by a rate, a colour determined by cost/income of consumption/generation and may be static for generation and flashing for consumption with a rate of flashing linked to the cost.

[0186] Within other embodiments a first visual characteristic relates to a first utility whereas a second visual characteristic relates to a second utility. For example, a horizontal bar upon a display may have a vertical position determined in dependence upon a speed of a bicycle (or treadmill, stationary bicycle etc.), the width (lateral size) of the horizontal bar determined in dependence upon a heart rate of the user of the bicycle, and the height (vertical size/thickness) a time averages estimated calories burnt (averaged for past minute for example).

[0187] Embodiments of the invention may be related to electricity as the utility wherein parameters associated with the utility may include, but are not limited to, rate of consumption, amount, power factor, current tariff/rate, next tariff/rate, consumption or generation, minimum, maximum, time averaged, first differential, second differential, electricity generation source (e.g. colour coded for wind, solar, coal, oil, gas, nuclear, hydro-electric, etc.), estimated greenhouse gas contributions, etc. Similar characteristics may be associated with other utilities such as gas, water, steam, heating oil etc. or associated with a user's solar panels, for example.

[0188] Embodiments of the invention may be related to vehicles and/or vehicle systems wherein parameters associated with the vehicle or vehicle system may include, but are not limited to, speed, current direction, next turn, fuel economy, electricity consumption/regeneration, battery level, output power, torque, revolutions per minute (RPM), G-force of maneuvers such as turns for example, distance, range of vehicle, trip segment(s) completed/remaining etc.

[0189] In addition to wheeled road vehicles the embodiments of the invention may be applied to marine based vehicles (vessels) or track based vehicles and/or systems such as trains, underground trains, subway trains, elevated trains (sky trains), chairlifts, funicular railroads etc. For example, with a marine vessel characteristics or attributes associated to the display may include, but not be limited to, current speed, wind direction, wind speed, tidal flow, water temperature, water temperature gradient, depth of water, rate of change of depth, turbine speed, relative propeller speeds, propeller shaft RPM, and tiller direction

[0190] Where the vehicle is air based characteristics or attributes associated to the display may include, but not be limited to, air speed, ground speed, altitude, rate of climb/descent, climbing or descending, pitch, yaw, roll, rate of change of pitch, yaw or roll, fuel level, engine RPM, etc. It would also be evident that characteristics can be associated with walking, bicycles, motorcycles, gliders, etc.

[0191] Other examples of applications include but are not limited to industrial systems, system status, production lines, stock market, exchange rate, Internet, email, text, simple message services, weather, queues, service times, etc.

[0192] Within the embodiments of the invention described and depicted supra a combination of colour and size have been primarily employed. However, it would be evident that a variety of visual cues may be employed including, but not limited to, the following: [0193] Colourwherein, for example, colour may change between two or more predetermined colours established in dependence upon factors such as cultural factors, personal preference, etc.; [0194] Transitionswherein, for example, transitions can be discrete, e.g. red to green or vice-versa, or continuous, e.g. red to violet through orange, yellow, green, blue and indigo, and may be linear or non-linear where continuous; [0195] Intensitywherein, for example, overall display may fade up/down (brighter-dimmer) or predetermined portions may vary; [0196] Flashwherein, for example, a pattern or icon may repeatedly go between on-off or between two colours etc. wherein the flashing frequency and/or flashing colours etc. are indicative of a characteristic; [0197] Cyclewherein, for example, rather than flashing between discrete states the display element or icon transitions continuously between two states with perceptible transition time; [0198] Speedwherein, for example, a shape may move through a predetermined trajectory, e.g. a dot going around in a circle or an arc rotating around a circle, where the speed of the motion is determined in dependence upon a characteristic; and [0199] Directionwherein, for example, up-down, left-right motions have associations either in terms of an icon or pattern overall or in terms of simulated motion etc.

[0200] However, it would be evident that a variety of other more complex visual cues may be employed including, but not limited to, exploiting single or multiple movements wherein, for example: [0201] a background undergoes one transition whilst a foreground icon or pattern undergoes a second transition; [0202] a background colour (or brightness level) varies whilst single (or multiple) display elements move in either direction; [0203] different colours moving in opposite directions with speeds in dependence upon characteristic of utility; [0204] two colours moving in same direction at different speeds in dependence upon characteristic of utility; [0205] use of background colour to indicate mode, e.g. light blue for water, with icon shape, geometry, movement for rate of consumption or deepening overall colour of a touch sensitive entry keypad with increasing consumption and displayed alphanumeric content for say, numbers, changing colour to high contrast; [0206] multiple icons of different colours moving at rates determined in dependence upon consumption rate, e.g. blue for water, green for gas, red for electricity with motion around periphery of display to allow other alphanumeric or visual content to be displayed.

[0207] However, it would be evident that a variety of other more complex visual cues may be employed including, but not limited to, exploiting single or multiple patterns or combinations of patterns wherein, for example: [0208] a series of concentric rings each denoting a characteristic with rotation rates dependent upon rate of characteristic and direction in dependence upon direction/sense of characteristic; [0209] an icon flashing with a persistence established in dependence upon characteristic; [0210] checkerboard with varying colours and varying weighting of colours established in dependence upon characteristic.

[0211] Within the preceding embodiments of the invention the display and utility are generally assumed to be co-located, e.g. electricity meter for a residence and residence occupant viewing a display within the residence. In such embodiments of the invention the display and meter may be wirelessly connected to the same network whereas in other embodiments of the invention the meter and display may be connected through a plurality of networks such as, for example a first wired or wireless interface from the meter to a telecommunications network and therein via that telecommunications network or multiple telecommunications networks the metered value communicated to the display via a second wired or wireless interface. Communications may be based upon proprietary protocols, appropriate standards, or exploit Internet Protocol (IP) communications for example. Within other embodiments of the invention the user may access metering data being transmitted to a remote server and access the metering data remotely via the remote server. Such an interface may allow a user to visualize a utility at times they are not within eyesight of the display wherein the user may access, for example, upon their PED.

[0212] Within the preceding embodiments of the invention the display and utility are generally assumed to be displaying with respect to a single utility. However, it would be evident from the preceding discussion that a visualization may relate to multiple utilities or that multiple visualizations may be concurrently or sequentially displayed to the user. Further, embodiments of the invention may support visualizations that are complementary to maintaining another use for the display. For example, an entry keypad/alarm system display may provide a visualization as part of the display around the periphery, to one side etc. Alternatively, a display may transition to a visualization when not in use for another function.
