Claim:
1. An apparatus comprising: a communication circuit configured and arranged to communicate wireless signals; an energy-transfer circuit, including an antenna, configured and arranged to receive wireless power and to power the apparatus via the received wireless power by converting an inductive field received via the antenna to current; a tamper-detection circuit including a loop conductor having first and second ends and contiguous conductive material extending between the first and second ends, the tamper-detection circuit being coupled to at least one end of the first and second ends of the loop conductor and being configured and arranged to provide a first output indicative of a connectivity characteristic of the loop conductor; and a validity-detection circuit configured and arranged to provide a second output indicative of a power overload condition and a validity condition corresponding to a power characteristic of power provided to the loop conductor that impacts a validity condition of the first output in response to the power characteristic of power provided to the loop conductor crossing a defined threshold beyond which the first output is susceptible to error, the communication circuit being configured and arranged with the tamper-detection circuit and the validity-detection circuit to transmit the wireless signals by transmitting a signal indicative of the first and second outputs, therein communicating an indication that the first output is valid or invalid, wherein the first output is invalid responsive to the power characteristic of power provided to the loop conductor being outside the defined threshold.
