Martin R Johnson, Jan F Finlinson, Jeremy P Willden, Robert E Gooch: Tamper-resistant, energy-harvesting switch assemblies. Angus C Fox III, November 26, 2013: US08592703 (39 worldwide citation)

Tamper-resistant, longer-lasting energy-harvesting switch assemblies that can accommodate longer antennas required for operation in the 315 MHz radio frequency band are provided. In order to accommodate longer antenna that will not fit within the energy-harvesting module, the front major face of the ...

Martin R Johnson, Jan F Finlinson, Jeremy P Willden, Robert E Gooch: Coded wireless key card sensor unit. Angus C Fox III, February 18, 2014: US08653939

A coded wireless sensor unit has a slot sized to receive a key card. When a key card is inserted into the slot, the act of insertion generates a energy-harvested power pulse, which powers circuitry that reads electrical device control information coded on the key card and creates a first information ...
