Abstract:

A radio frequency identification exciter ( ) includes a plurality of antenna elements ( ) that are spaced to define active areas ( ). A matrix switch ( ) flexibly connects the plurality of antenna elements to an exciter circuit ( ). Independent switches ( ) are selectively switched such that an electric field is generated between at least two antenna elements whereby radio frequency identification tags ( ) in the vicinity of the two antenna elements are capacitively powered to exchange data with the exciter. Antenna elements other than the at least two antenna elements may be selectively coupled to a signal from the exciter circuit that inhibits activation of radio frequency identification tags in the vicinity of those antenna elements. The matrix switch preferably comprises polymer-based circuits.

International Classification:

H04Q 700

US Classification:

370329, 370342

Abstract:

A source device ( ) stores predetermined data and establishes a channel selection profile comprising a plurality of channel selections. Each channel selection is derived from a subset of the predetermined data. The source device ( ) transmits at least a portion of the predetermined data over at least a first channel selected from the channel selection profile.

Michael L. Bushman - Hanover Park IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G06F 1700

US Classification:

235375

Abstract:

In accordance with the present invention, a radio frequency identification (RFID) device comprises a plurality of data fields. The RFID device transmits a data symbol from a data field, receives an acknowledgement symbol, and compares the transmitted data symbol to the received acknowledgement symbol. The RFID device repeats these steps until data transmission is complete as long as each transmitted data symbol is equivalent to a corresponding received acknowledgement symbol; otherwise, the RFID device maintains the data field from which the last data symbol was transmitted, and temporarily suspends data transmission. When the RFID receives a request for RFID devices temporarily suspended in a given data field to resume data transmission, if the given data field in the request is equivalent to the data field that was maintained, the RFID device repeats the steps above starting with the first symbol in the data field that was maintained.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G06F 1300

US Classification:

710305, 710100

Abstract:

An architecture for a computer system that has lower complexity than prior computer system architectures. In one embodiment the functionality that in prior computer system architectures resides in a central processing unit (CPU) is split between a CPU and a program control unit. This allows the CPU to have lower complexity and can permit the computer system to have greater flexibility and lower cost. In another embodiment the computer system contains a memory mapping unit. The memory mapping unit enables the computer system to use one of a plurality of peripherals without changing the instruction codes of the CPU thus increasing the flexibility of the computer system.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G08B 13/14

US Classification:

3405721, 34082571, 34082573, 34082576, 375275, 375326, 375335

Abstract:

A radio frequency identification system comprising a radio reader circuit operable to emit a radio frequency carrier signal modulated with a subcarrier, which has a subcarrier modulation rate. The radio frequency identification tag circuit is operable to extract the subcarrier from the emitted radio frequency carrier signal and the extracted subcarrier then functions as a clock, which operates to assist in the transfer of a modulated backscattered signal to the radio frequency identification reader circuit. The radio frequency identification reader circuit decodes the modulated backscattered signal and the data encoded in the radio frequency identification tag circuit is obtained.
