Abstract

A method and system for preventing a wireless device from interfering with equipment within a sensitive area is disclosed. The method comprises transmitting a radio signal from the sensitive area to the wireless device; receiving the radio signal by the wireless device; and then deactivating at least one portion of the wireless device based upon receiving the radio signal. A system and method in accordance with the present invention allows for the automatic deactivation of a portion of a wireless device that is disruptive to the sensitive area. For example, if the user is utilizing a laptop computer which emits radiation that might interfere with successful operations of an airplane, those portions of the laptop that emit radiation that is disruptive would be turned off automatically but other functions of the laptop computer would still be available to the user.

Claims

1. A method for preventing a wireless device from interfering with equipment in a sensitive area, the wireless device including at least one function which can disrupt the equipment in the sensitive area, comprising the steps of:

(a) transmitting a radio signal to the wireless device;

(b) receiving the radio signal by the wireless device; and

(c) deactivating the at least one function of the wireless device based upon receiving the radio signal.

2. The method of claim 1 wherein the radio signal is transmitted continuously.

3. The method of claim 1 wherein the radio signal is transmitted periodically.

4. The method of claim 1 wherein the radio signal includes a command to deactivate the at least one function.

5. The method of claim 1 wherein the radio signal deactivates the wireless device.

6. A wireless device comprising:

a plurality of functions; and

a receiver mechanism coupled to at least one of the plurality of functions, the receiver mechanism for deactivating the at least one of the plurality of functions if a radio signal is received which indicates that the at least one function should be deactivated.

7. The device of claim 6 wherein the radio signal is transmitted continuously.

8. The device of claim 6 wherein the radio signal is transmitted periodically.

9. The device of claim 6 wherein the radio signal includes a command to activate the at least one function.

10. A system for preventing a wireless device from interfering with equipment in a sensitive area;

the system comprising;

a transmitter for providing a radio signal; and

a receiver mechanism within the wireless device for deactivating at least one function within the wireless device when the radio signal is received by a wireless device.

11. The system of claim 10 wherein the radio signal is transmitted continuously.

12. The system of claim 10 wherein the radio signal is transmitted periodically.

13. The system of claim 10 wherein the radio signal includes a command to deactivate the at least one function.

14. The system of claim 10 wherein the receiver mechanism comprises:

a receiver circuit; and

a deactivation circuit coupled to the receiver circuit and the at least one function.
