Alarm systems, remote communication devices, and article security methods
First Claim
1. An alarm system comprising:
- a base communication device configured to implement wireless communications;
a remote communication device configured to communicate with the base communication device using the wireless communications, wherein the remote communication device is adapted to be associated with an article to be secured and wherein the remote communication device comprises alarm circuitry;
wherein the remote communication device is configured to generate a first signal responsive to one of the wireless communications of the base communication device and wherein the first signal comprises a characteristic configured to identify the first signal as being generated responsive to wireless communications of the base communication device;
wherein the remote communication device is configured to generate a second signal responsive to the reception of spurious electromagnetic energy by the remote communication device and wherein the second signal comprises the characteristic; and
wherein the remote communication device is configured to distinguish the first signal from the second signal and to generate a human perceptible alarm signal responsive to the distinguishing and the generation of the first signal.
