Abstract:
A device for RF energy transmission comprising:a transmitting device for transmitting data signals and energy;a receiving device for receiving the data signals and energy; andan actuator coupled to said receiving device;wherein the receiving device comprises:a sensor selected from the group consisting of a frequency detector, a voltage value detector, a time detector, and a detector for measuring external physical quantity, anda control unit responsive to said sensor for tripping said actuator;wherein the energy required by said receiving device is wirelessly transmitted from said transmitting device to said receiving device;wherein the energy required by said actuator is wirelessly transmitted from said transmitting device to said receiving device;wherein tripping of said actuator is selectively controllable; andwherein the energy required to supply said actuator and said sensor is transmitted simultaneously with a data transmission and energy transmission required by said receiving device to said receiving device, or is transmitted after a time period in which a bi-directional data communication between said transmitting device and said receiving device occurs, provided that said data is authenticated or verified.
