Patent ID: 8144197

Claim:
A first communication module, comprising: a transceiver disposed to wirelessly receive a first data signal from a second communication module indicating detecting of an object at the second communication module; a proximity sensor disposed to sense proximity of an object within a sensing field; a processor coupled to the transceiver and to the proximity sensor for generating a second data signal indicating detection of the object within a sensing field responsive to confirming the detection of the object at the first communication module and the second communication module by correlating a sensor signal of the proximity sensor with the first data signal, the processor disposed to select a third communication module for transmitting the second data signal to a destination based on an amount of energy consumed to transmit the second data signals to the destination via the third communication module; and an image capturing device configured to capture a first image of the object, the image capturing device selectively turned on in response to confirming detection of the object at the first communication module and the second communication module, the first image sent to the destination via the third communication module for comparison with a second image stored in the destination.
