Abstract:
An electronic lockset with a radio frequency harvesting circuit. In one embodiment, the electronic lockset includes a mechanical locking portion movable between a locked position and an unlocked position. One or more energy consumption devices are provided that actuate the mechanical locking portion between the locked position and the unlocked position. A rechargeable battery provides electrical power to the energy consumption devices. A radio frequency (“RF”) transmitter and RF energy harvesting circuit are used to wirelessly recharge the battery. Typically, the RF transmitter is configured to transmit at a predetermined frequency. The RF energy harvesting circuit is tuned to the predetermined frequency and is electrically coupled with the rechargeable battery to recharge the battery.
