Abstract: A radio frequency identification exciter (200) includes a plurality of antenna elements (122a-i) that are spaced to define active areas (130a-e). A matrix switch (202) flexibly connects the plurality of antenna elements to an exciter circuit (203). Independent switches (204a-i) are selectively switched such that an electric field is generated between at least two antenna elements whereby radio frequency identification tags (132) 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.

Abstract: An electronic signal communication system for processing remote signals to be conveyed from a subscribed transmitting client to a subscribed receiving client. Several transmitters, each having first and second inputs, are linked with remotely located sets of receivers compatible with the communications links used. A generating signal assembly generates a first signal and a plurality of second signals. The first signal includes control and possibly data information. The second signals enable one of several transmitters. Once received, a detector and selector assembly detects the receiver's active output and conveys the information to a subscribing recipient who in turn has one or more actuating devices controlling the conventional controllable resources of the subscribed recipient.

Abstract: Several rotator switch architectures are provided that enhance performance of a basic rotator switch. The rotator switches having double buffered tandem nodes, multiplexing two or more sources onto each tandem node, partitioning the rotator into two or more parallel space switches, two or more rotator planes multiplexing front/to source and destination nodes to provide data path redundancy, priority queueing on source nodes scheduled locally or globally, or redundancy in the schedulers are shown.
