Abstract

A device for wireless energy transmission and preparing of a remote actuator wherein energy is transmitted from a transmitting device to a receiving device coupled to the actuator. Mechanical and/or electrical movements are executed by the receiving device in response to a coded data transmission. The energy transmitted from the transmitting device to the receiving device serves to supply an actuator executing the mechanical and/or electrical action with energy. The actuator is tripped, remotely controlled by the transmitting device, or automatically by at least one sensor of the receiving device.

Claims

1. 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; and

an 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, and

a 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; and

wherein 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.

2. The device as claimed in claim 1, wherein said actuator is controlled by the transmitting device by remote control.

3. The device as claimed in claim 1, wherein at least one actuator is controlled within the receiving device by a sensor of the receiving device.

4. The device according to claim 1, wherein the data signal of said transmitting device includes a code that is compared to a code located in the receiving device before the actuator can be tripped.

5. The device according to claim 1, wherein said actuator is tripped upon authentication of data exchanged between the transmitting device and the receiving device.

6. The device according to claim 1, further comprising at least one temporary energy storage in the receiving device chargeable by energy transmitted from said transmitting device to said receiving device and supplying said actuator with energy required by the actuator during peak consumption, and wherein said actuator is tripped by a coded signal.

7. The device as claimed in claim 6, wherein the storage supplies said receiving device with energy during transmission breaks.

8. The device as claimed in claim 1, wherein the receiving device further comprises a logic circuit for evaluating the sensor signals.

9. The device according to claim 8, wherein the receiving device comprises a logic element or processor circuit for evaluating remotely controlled signals of the transmitter.

10. The device according to claim 9, wherein said receiving device further comprises a decoder for evaluating authentication data transmitted by said transmitting device wherein said decoder releases said actuator if said authentication data is valid.

11. The device according to claim 10, wherein said receiving device further comprises a separate data transmitter, and said transmitting device comprises a decoder and a separate data receiver for bi-directional communication, wherein said authentication data is stored in both a memory unit of said transmitting device and in a memory unit of said receiving device, said decoders of the transmitting and receiving devices controlling the evaluation of said authentication data exchanged between said transmitting device and said receiving device so that the validity of the transmitted data can be checked wherein said actuator is releasable only if the authentication data is valid.

12. The device as claimed in claim 11, wherein authentication activities are stored in a memory unit of said transmitting device and said receiving device.

13. The device according to claim 11 wherein said actuator and said sensor are releasable only if the authentication data is valid.

14. The device as claimed in claim 10, wherein the receiving device further comprises separate temporary energy storages for said actuator, said sensor, said decoder, said processor circuit, and said control unit.

15. The device according to claim 14, wherein said separate temporary energy storages comprise:

a first energy source comprising a capacitor having a low capacitance for supplying power to said sensor, said decoder, said processor circuit, and said control unit; and

a second energy source comprising a capacitor having a high capacitance for supplying power to said actuator.

16. The device according to claim 1, wherein the actuator is designed to form a lock or opener.

17. The device as claimed in claim 16, wherein said device serves to actuate the lock or opener of a door of a vehicle, lot or plot of land, building, container for goods or the cover of a cassette box for valuables, or a collection container for valuable materials or wastes.

18. The device according to claim 17, wherein the lock or opener is individually coded and the actuator serves to release the individually coded lock or opener as a master key.

19. The device according to claim 1, further comprising a plurality of actuators for executing an action wherein tripping of said action is controlled by each actuator.
