Abstract

A safety device for vehicles. The device inhibits use of communication devices that run the risk of distracting a driver/operator while the vehicle is in motion. Several techniques for inhibiting use are described which can be used individually or in a complementary combinations. In one technique, a rapidly varying signal level is created local to the communication device. The variations exceed the operational limits of the system, thereby inhibiting communications. The device may be in a constant-on mode, unless it detects an attempt to make a communication classified as appropriate. Such a device may inhibit short messages, such as “text” messages and may also allow or, in some embodiments, place emergency calls.

Claims

1. A method of preventing operation of a communication device, the method comprising:

with a safety device, causing operation of the communication device within the vehicle to be inhibited;

selectively controlling the safety device to cease causing operation of the communication device to be inhibited by;

detecting a condition; and

in response to the detecting the condition, controlling the device to suspend inhibiting operation of the communication device.

2. The method of claim 1, wherein:

detecting the condition comprises detecting an emergency condition.

3. The method of claim 2, wherein:

detecting the emergency condition comprises receiving user input indicating an emergency condition.

4. The method of claim 3, further comprising:

in response to detecting the emergency condition, automatically placing an emergency call.

5. The method of claim 1, wherein:

detecting the condition comprises detecting operation of a communication device by an occupant of a vehicle who is not operating the vehicle.

6. The method of claim 5, wherein:

detecting operation of the communication device by an occupant of the vehicle who is not operating the vehicle comprises detecting an RF signal originating from a passenger seat of the vehicle.

7. A method of selectively limiting operation of a communication device within a vehicle, the method comprising:

with a safety device, causing operation of the communication device within the vehicle to be inhibited;

detecting a condition under which operation of the communication device is appropriate; and

in response to the detecting the condition, controlling the device to suspend inhibiting operation of the communication device.

8. The method of claim 7, wherein the vehicle comprises an automotive vehicle or a rail locomotive.

9. The method of claim 7, wherein:

detecting the condition comprises detecting a transmission emanating from a passenger seat of the vehicle.

10. The method of claim 7, wherein:

causing operation of the communication device within the vehicle to be inhibited comprises emitting a signal;

controlling the device to suspend inhibiting operation of the communication device comprises suspending emission of the signal; and

the signal, unless suspended, is emitted when an engine of the vehicle is in operation.

11. The method of claim 7, wherein:

causing operation of the communication device within the vehicle to be inhibited comprises emitting a signal that limits operation of the communication device within the vehicle; and

emitting the signal that limits operation of the communication device within the vehicle comprises controlling the safety device to generate a radio frequency signal that limits operation of the communication device.

12. The method of claim 7, wherein:

causing operation of the communication device within the vehicle to be inhibited comprises emitting a signal that limits operation of the communication device within the vehicle; and

emitting the signal that limits operation of the communication device within the vehicle comprises controlling the safety device to cause variations of a level of a signal of the type received by the communication device from a base station, wherein the variations have an amplitude and occur at a frequency that limits operation of the communication device.

13. The method of claim 12, wherein:

the variations of the level of the signal comprise variations in amplitude of at least 7 dB at a rate faster than 300 Hz.

14. The method of claim 7, wherein:

causing operation of the communication device within the vehicle to be inhibited comprises generating a masking signal that limits operation of the communication device.

15. The method of claim 7, wherein:

causing operation of the communication device within the vehicle to be inhibited comprises creating a radio frequency environment that causes communications to be inhibited.

16. A safety device to selectively limit operation of a communication device within a vehicle, the device comprising:

a control;

a cellular transceiver;

a controller adapted to;

limit operation of the communication device within the vehicle in response to detection of an operating condition of the vehicle; and

in response to user activation of the control, initiate a communication through the cellular transceiver.

17. The safety device of claim 16, further comprising:

a motion detector coupled to the controller, the motion detector adapted to detect motion of the vehicle,

wherein the operating condition comprises motion of the vehicle detected by the motion detector.

18. The safety device of claim 16, wherein:

the cellular transceiver is a limited-purpose cellular transceiver configured to place an emergency call.

19. The safety device of claim 16, wherein:

the control comprises a button.

20. The safety device of claim 16, wherein:

the controller is adapted to switch a state of the passive device to cause variations of a level of a signal of the type received by the communication device from a cellular base station, wherein the variations limit operation of the communication device within the vehicle.

21. The safety device of claim 16, further comprising:

an amplifier,

wherein the controller is adapted to control a gain of the amplifier to cause variations of a level of a signal of the type received by the communication device from a cellular base station, wherein the variations create a fast fading environment that limits operation of the communication device within the vehicle.
