Patent ID: 8558714

Claim:
A detection system comprising: a first base station defining a first detection area and comprising: a first transmitter configured to transmit a first detection signal; and a first communication receiver configured to receive a first communication signal and a second communication signal; a first sensor having a first unique identifier and being movable relative to the first base station, the first sensor comprising: a first detector configured to detect the first detection signal; and a first communication transmitter configured to selectively transmit the first communication signal together with the first unique identifier in response to the first detection signal; and a second sensor having a second unique identifier and being movable relative to the first base station, the second sensor comprising: a second detector configured to detect the first detection signal; and a second communication transmitter configured to selectively transmit the second communication signal together with the second unique identifier in response to the first detection signal; wherein the first base station is configured to facilitate variation in the operation of a device based at least in part upon at least one of the first unique identifier and the second unique identifier.
