Patent ID: 8254310

Claim:
A wireless response system, comprising: a plurality of response units, each having a wireless response transceiver and an input device, said input device adapted to receiving a user input selection, said wireless response transceiver adapted to receive a base transmission and to transmit a response transmission in response to receipt of a base transmission; a plurality of base units, each having a wireless base transceiver, said base transceiver adapted to transmit base transmissions and receive the response transmissions from said response units; wherein each of said base units and each of said response units adapted to be assigned a communication identification, wherein each of said response units is adapted to exchanging wireless transmissions with one of said base units having a common communication identification with that one of said response units; wherein each of said base units is adapted to be assigned a base address that is different from the base addresses of the other of said base units, wherein the base transmissions include the base address of the one of said base units transmitting that base transmission and wherein each of the response transmissions includes the base address of the base transmission to which that response transmission is responding; wherein each of said base units is adapted to process the response transmissions having a base address in common with the base address of that base unit and not process response transmissions not having a base address in common with the base address of that base unit; and wherein at least some of said plurality of base units and some of said plurality of response units are assigned a common communication identification, wherein each of said response units having the common communication identification responds to the first of the base transmissions received from one of said at least some of said plurality of base units and only responds to a subsequent base transmission having the same base address as the base address of the first of the base transmissions received, wherein a response unit will temporarily lock on to one of the base units until it has received a subsequent base transmission from that one of the base units.
