Classification: CPC H | IPC H

Claim 16:
17. An apparatus comprising:
wireless receiver hardware operative to wirelessly receive energy and store the received energy in an energy storage device to produce a supply voltage; and
a controller operative to:
i) monitor a magnitude of the supply voltage stored in the energy storage device; and
ii) during cyclical ON/OFF control of supplying power from the supply voltage to a mechanical load, prevent the magnitude of the supply voltage from falling below a voltage threshold level, the magnitude of the supply voltage applied to the mechanical load above the voltage threshold level causing physical movement of the mechanical load;
wherein the voltage threshold level is a first voltage threshold level;
wherein the energy storage device is a capacitor;
wherein the cyclical ON/OFF control includes implementation of multiple ON/OFF control cycles;
wherein the controller, for each respective ON/OFF control cycle of the multiple cyclical ON/OFF control cycles, is operative to:
i) for an ON portion of the respective ON/OFF control cycle, activate switch circuitry to an ON-state to convey the supply voltage to the mechanical load; and
ii) for an OFF portion of the respective ON/OFF control cycle, deactivate the switch circuitry to an OFF-state to prevent conveyance of the supply voltage to the mechanical load;

wherein the magnitude of the supply voltage stored in the capacitor is controlled to be greater than the first voltage threshold level during the ON portion of the respective ON/OFF control cycle; and
wherein the magnitude of the supply voltage stored in the capacitor is greater than the first voltage threshold level during the OFF portion of the respective ON/OFF control cycle.
