Abstract:
A system for controlling shopping carts usage in the vicinity of a parking lot, the system comprising: a device that repeatedly transmits a lock command from a directional antenna (282), said directional antenna mounted above ground and angled downward to create a lock zone (286) in which shopping cart use is restricted, said lock zone encompassing an exit area associated with the parking lot; and a plurality of shopping carts, each shopping cart comprising a brake mechanism, and comprising an RF communication circuit that is responsive to the lock command by activating the brake mechanism.
Abstract:
A device having a switched impedance that can be switched between a first state and a second state wherein, in the first state, the device acts as a voltage multiplier and, in the second state, the device acts as a rectifier.

Abstract:
A system having a UHF RFID transceiver is adapted to communicate exclusively with a single electro-magnetically coupled transponder located in a predetermined confined transponder operating region. The system includes a near field coupling device comprising a plurality of lines connected in parallel with an unmatched load. The near field coupling device may be formed, for example on a printed circuit board with a plurality of electrically interconnected traces and a ground plane. The system establishes, at predetermined transceiver power levels, a mutual electro-magnetic coupling which is selective exclusively for a single transponder located in a defined transponder operating region. Also included are methods for selective communication with the transponder in an apparatus such as a printer-encoder.
