Wirelessly Powered Input Device

A battery-less wireless input device, comprising:

• a processing system configured to:
• couple with a short-range communications target, the short-range communications target including an energy harvester for harvesting energy generated by a short-range communications initiator when the short-range communications initiator communicates with the short-range communications target;
• and
• receive the harvested energy for powering the battery-less wireless input device from the energy harvester when the short-range communications initiator communicates with the short-range communications target.

A computer program product, comprising:

• a computer-readable medium comprising code for:
• coupling a battery-less wireless input device with a short-range communications target, the short-range communications target including an energy harvester for harvesting energy generated by a short-range communications initiator when the short-range communications initiator communicates with the short-range communications target;
• and
• receiving in the battery-less wireless input device the harvested energy for powering the battery-less wireless input device from the energy harvester when the short-range communications initiator communicates with the short-range communications target.

A system for powering a battery-less wireless input device, comprising:

• a battery-less wireless input device;
• a short-range communications target coupled to the wireless input device, the short-range communications target including an energy harvester for harvesting energy;
• and
• a short-range communications initiator for generating energy harvested by the energy harvester when the short-range communications initiator communicates with the short-range communications target,
• wherein the energy harvester powers the wireless input device with the harvested energy when the short-range communications initiator communicates with the short-range communications target.
