1. A wireless remote control operable to control at least one remote device, comprising:
- at least a first antenna configured to receive carrier waves from a carrier wave source that is separate and distinct from the wireless remote control;
at least a first passive power supply circuit configured to modulate at least some of the carrier waves received via the first antenna with information, and to cause the wireless remote control to backscatter the modulated carrier waves; and
at least the first user actuatable switch operable to selectively cause the first passive power supply circuit to modulate the received carrier wave with a first piece of information.

Abstract
Wireless remote control may omit batteries. A carrier wave from an external carrier wave source may be modulated and backscattered with information identifying a user selection. The backscattered modulated carrier wave response may be received and interpreted for controlling one or more electronic devices.

12. A wireless, batteryless, remote control operable to control at least one remote device, comprising:
-
at least a first antenna configured to receive carrier waves from a carrier wave source, the carrier wave source being separate and distinct from the wireless, batteryless, remote control; at least a first user actuatable switch; and at least a first passive power supply circuit operatively coupleable to at least the first antenna by at least the first user actuatable switch, and configured to modulate at least some of the carrier waves received via the first antenna with a first piece of information, and to cause the wireless, batteryless, remote control to backscatter the modulated carrier waves, wherein the first user actuatable switch is operable to selectively electrically couple at least the first antenna to the first passive power supply circuit and electrically uncouple at least the first antenna from the first passive power supply circuit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
