Claim:
An apparatus comprising: a self-contained power supply; a helicoil dipole antenna coupled to the power supply; a transmitter coupled to the power supply; a receiver coupled to the power supply and configured to receive signals from remote transmitters at a designated frequency; a computer processor coupled to the power supply; a memory device coupled to the computer processor and configured to store an identifier associated with the apparatus; one or more sensor devices that provide information regarding health status of a person or object; logic instructions embedded on the memory device, the logic instructions configured to: compare an identifier decoded from received signals to the identifier associated with the apparatus; and when the identifier decoded matches the identifier associated with the apparatus; decode a return frequency from the signal, and generate return signals, wherein the return signals include the identifier associated with the apparatus, and the transmitter is activated only when the transmitter transmits the return signals at the return frequency; wherein the return signals include an address of the apparatus as the identifier and information regarding a person or an object associated with the apparatus but not a physical location of the person or the object, wherein the information includes the information regarding health status of the person or object; wherein the received signals include a wake up code, an encryption code, transmit data rate, operation mode, the identifier, and the return frequency; and wherein the logic instructions are further configured to determine whether the apparatus was removed from the person or object and include data in the return signal that indicates whether the apparatus was removed from the person or object.
