Abstract

A system and a method for securing electric apparatus, that includes at least one transmitter transmitting at least one coded signal, and where the system includes at least one electric apparatus interacting with at least one decoder. To prevent electric apparatus from being used in other places than where intended, a one-way communication system causes the apparatus to lose their practical value if they are stolen. Activation of the electric apparatus is conditional on the transmitter transmitting a coded signal to at least one decoder that receives the coded signal and interacts with at least one electronic switch for establishing power supply to the apparatus. By using a device that switches off the power supply or other essential electric circuit for the electric apparatus in case that the decoder does not receive and decode the transmitted signals, it is possible to protect electric apparatus very efficiently against theft.

Claims

1. A system for securing electric apparatuses, the system including at least one transmitter, the transmitter transmitting at least one coded signal, where the system includes at least one electric apparatus, the apparatus interacting with at least one decoder, whereby activation of the electric apparatus is conditional on the transmitter transmitting the at least one coded signal which is received at least the one decoder, and where the at least one decoder interacts with at least one electronic switch for establishing power supply to the apparatus.

2. System according to claim 1, whereby the at least one decoder for decoding the signals transmitted by the transmitter is integrated in at least one electric apparatus.

3. System according to claim 1, wherein the at least one decoder is an external unit which transmits signals to the apparatus, where the apparatus contains means for decoding the signal.

4. System according to claim 3, whereby the transmitter is adapted to be activated via at least one code at one of installation and if the power disappears.

5. System according to claim 4, whereby said at least one transmitter is adapted to transmit signals to the at least one decoder via at least one electric network.

6. System according to claim 4, whereby the decoder is adapted to receive signals from the at least one transmitter via a wireless network.

7. (canceled)

12. A method for securing electric apparatuses, comprising the steps of:

transmitting coded signals from at least one transmitter;

using at least one decoder at least one electric apparatus for receiving said coded signals, and

supplying the at least one electric apparatus with power when the at least one decoder receives and decodes the coded signals transmitted from the at least one transmitter, and

breaking of an electric circuit in the apparatus when the decoder fails to receive the coded signal from the at least one transmitter.

8. Method according to claim 12, whereby the transmitter transmits signals to the at least one decoder via at least one electric network.

9. Method according to claim 8, whereby the method includes the application of means for decoding the signals transmitted by the transmitter using an external unit which transmits signals to the apparatus, where the signals from the external unit are decoded by a means for decoding in the apparatus.

10. Method according to claim 9, whereby the transmitter is activated via at the least one code at one of installation and if the power disappears.

11. Method according to claim 12, whereby the decoder receives signals from the at least one transmitter via a wireless network.
