Anurag Goel - Pleasanton CA, US
Mark Douglas McDonald - Campbell CA, US
Sunit Saxena - Monte Sereno CA, US
Jih Lung Wang - San Jose CA, US

Assignee:

Altierre Corporation - San Jose CA

International Classification:

G06K 15/00

US Classification:

235383, 705 20

Abstract:

A multiuse system for use with Wireless Display Tags (WDTs) includes, in one or more exemplary arrangements, techniques for automatically maintaining synchronicity between pricing data for a product and advertising, marketing or promotional data associated with that product, and for detecting the proximity and location of a customer within a category of goods displayed within a managed environment. A messaging format suitable for such low power operation among a large number of peers is also disclosed, as is a technique for integrating a plurality of smaller displays to yield a single large display. An access point capable of serving as a communications hub within such a network, while at the same time offering visual and audio surveillance capabilities, is also disclosed.

Appl. No.:

11/019978

Inventors:

Anurag Goel - Pleasanton CA, US

Mark Douglas McDonald - Campbell CA, US
Leonard Mark Dorfman - Santa Clara CA, US

Assignee:

Altierre Corporation - San Jose CA

International Classification:

G06K 15/00

US Classification:

235383, 235385

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.

Assignee:

Altierre Corporation - San Jose CA

International Classification:

G06K 15/00

US Classification:

235383, 235385

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.

Filed:

Nov 13, 1996

Appl. No.:

8/747845

Inventors:

Mark Douglas McDonald - Fremont CA
Paul Anthony Denny - Cupertino CA
Thai Minh Nguyen - Santa Clara CA
David Edward Bien - Tucson AZ

Assignee:

National Semiconductor Corporation - Santa Clara CA

International Classification:

H04B 144

US Classification:

455 83

Abstract:

A radio frequency switch includes a field-effect-transistor (FET) having a gate connected to a voltage multiplier. The control voltage for the switch is delivered to the voltage multiplier which delivers an increased gate voltage to turn the switch on. The voltage multiplier is driven by fluctuations of the control voltage as a transceiver, for example, is switched from the transmit to the receive mode.
