Abstract: A wireless display tag, adapted to fit within the C-channel of a shelf-edge, or otherwise usable as a hang tag or small identification device, includes, depending on implementation, an active transceiver, a passive transceiver, or both, with analog and digital control portions for managing communications with a host.

Abstract: A method for error free initialization of a display tag includes providing a display tag, scanning the display tag with a near field source to cause the display tag to generate identification indicia, storing the identification indicia if only a single display tag generates that identification indicia, scanning the barcode of a product to be associated with the display tag, and associating, in a database, the identification indicia of the display tag with the barcode of the product to be associated with that display tag.

Abstract: A low-profile Wireless Display Tag (WDT) fits within the confines of a retail store display shelf-edge C-channel. The WDT may also be used to tag high-value retail item units where it can simultaneously function as a price tag, and an anti-theft device. The invention provides for bidirectional communication between the WDT and a central database. The invention uses a low profile antenna that may be painted onto a surface within the WDT. The WDT is capable of displaying graphics or variable format alphanumeric characters and the placement of display items is user programmable. The WDT uses an RF integrated Circuit (RFIC) that combines the backscatter RF communications method, amplified backscatter RF communications method and the active RF communications method.

Abstract: A snap-together electronic watch module frame and assembly includes a plastic front pod member having a first recess to receive and locate the electrooptical display, a rear pod member having a second recess to receive the timepiece battery, and an intermediate pod member sandwiched therebetween adapted to carry and position a printed circuit board with an integrated circuit chip, oscillator, capacitor, conductors and the like thereon in preselected relation to the display and battery. The module assembly is held together by resilient gripping arms molded into either the front or rear pod member snap-fitted onto shoulders molded on the other pod member. The intermediate pod member is molded to include on or more depending alignment legs adapted to fit in alignment holes molded in the rear pod member to properly position the circuit board components relative to the display and battery.
