A self-expiring band structure is activated upon the contacting of two chemical constituents together. This contacting may be performed by the attachment action of the band or independently thereof. After a time duration has passed, the coaction of the chemical constituents result in a visually perceptible change can alert others to the fact the band has expired. These bands may be both printable, such as by a printer or other machine printing, as well as time-expiring making them a very versatile product that offer heightened security at the price point closer to that of a disposable item because they do not require complex infrastructure for validation.

This Graphic Band Assembly includes a band/strap that may be worn and is printed with a graphic image made up of electroluminescent segments. The graphic image on the band/strap is animated by the programming of circuitry contained in underlying layers of the band/strap which causes the selective illumination of the segments. The Graphic Band Assembly includes a PCB control unit and a rechargeable battery that contain the illumination program, control the EL illumination pattern, and provide the power to illuminate the EL Band. The Assembly includes accessible switches that allow the unit to be turned on and off, and to switch between programs. The Assembly includes a USB port for recharging and programming the device.

An electronic device may be attached to an external item. The electronic device may include an optical identification sensor configured to sense a color-encoded tag in the external item when the item is attached to the device. The optical identification sensor may include a board layer, a protective filter layer, wall structures for supporting the protective filter layer on the board layer, a linear array of photodetectors disposed between the board layer and the protective filter layer, a field-of-view restriction filter interposed between the photodetectors and the protective filter layer, and a light source having multiple emitters for illuminating the color-encoded tag. The emitters may be activated sequentially to produce multiple images that are combined to reconstruct an accurate reading of the color-encoded tag, which can then be used to identify the type of external item currently attached to the electronic device.

Systems and methods include tamper-evident indicators applied to a band comprising a strap that forms a closed loop. Tamper-evident sections of the indicators provide increased security against accidental and intentional removal of the indicators. Indicators are provided with adhesives and bare areas devoid of adhesive allowing easy and secure application of indicators to bands while they are being worn and with greater ease. Indicators can be further provided with liners protecting the adhesives allowing the indicators to be easily applied by gloved hands, reducing contamination risks. Contamination and wear risks can be further reduced by supplying indicators with antimicrobial surfaces and overprint varnishing.

A communication system ad methods that includes a RFID tag writer to assign a unique identification to RFID tags, a series of personal communication devices, that have an RFID tag, a processor, a signal receiver and a display, and processors provide instructions to the displays to provide different light sequences in response to signals received, and a central controller that includes a processor, a transceiver and a memory, where the memory stores information relating to the RFID tags, user accounts and has an input device that allows users to be segregated into defined groups and stored, and the controller receives signals from tag readers or communication devices and transmit signals to the personal communication devices to affect the displays.

An apparatus for automatic radio-frequency identification (RFID). In an embodiment, the apparatus comprises a flexible strap comprising a plurality of holes and a buckle configured to buckle to any one of the plurality of holes, such that, when the buckle is buckled to one of the plurality of holes, the strap forms a closed loop. The apparatus further comprises one or more tag enclosures. Each tag enclosure comprises one or more buckles and a RFID tag configured to communicate identifying data to a reader device. The one or more buckles of each tag enclosure are each configured to buckle to any one of the plurality of holes on the strap such that the tag enclosure may be attached to the strap at any one of a plurality of positions on the strap.

A wearable RFID device is disclosed herein. The wearable RFID device is preferably comprised of a band, one or more RFID inlays attached to a backside of said band, and at least one tamper resistant cut or notch in one or more of the band and/or the RFID inlays so that the RFID inlay(s) are rendered inoperable or destroyed when the wearable RFID device is removed from the user. The band is preferably formed by attaching a first and a second end of the band with an adhesive to form an adhesive closure, and the RFID inlay may be positioned on either side of, or extend across, the adhesive closure to suit user preference or other design considerations.

A combination wristband and label form. The form comprises a front side formed of paper. The front side has a first portion having a plurality of labels die cut therein and a second portion having a void. A back side of the form has a polyester section comprising a wristband defined by die cuts in the polyester section and removable from the form. The single-ply wristband has a strap and a foldable having a first panel and a second panel. The first panel has an imaging area defined by a coating and the second panel is configured to laminate only a portion of the imaging area. A size of the second panel is disparate from a size of the first panel.

An electronic device may be attached to an external item. The electronic device may include an optical identification sensor configured to sense a color-encoded tag in the external item when the item is attached to the device. The optical identification sensor may include a board layer, a protective filter layer, wall structures for supporting the protective filter layer on the board layer, a linear array of photodetectors disposed between the board layer and the protective filter layer, a field-of-view restriction filter interposed between the photodetectors and the protective filter layer, and a light source having multiple emitters for illuminating the color-encoded tag. The emitters may be activated sequentially to produce multiple images that are combined to reconstruct an accurate reading of the color-encoded tag, which can then be used to identify the type of external item currently attached to the electronic device.

A clasp is configured to permanently interlock around a flexible strip of material and includes first and second interlocking members. At least one interlocking member includes a Bluetooth communication device. Each interlocking member can include a plurality of hooks and a corresponding plurality of recesses, where the recesses of one interlocking member receive the hooks of the other interlocking member to secure a band within the clasp between the interlocking members. The recesses can be completely internal to the clasp to prevent external tampering. Each of the interlocking members can include various protrusions and ribs that compress and secure the band within the clasp, so as to prevent movement of the band between the interlocking members when interlocked.
