Abstract

A location based audio reception zone system for use in vehicle includes a driver'"'"'s seat and one or more passenger seats. A radio frequency (RF) transmitter is used for transmitting entertainment content to one or more headsets located in a passenger seat. The RF transmitter transmits in a predefined reception zone for disabling audio in a headset located within the zone for preventing a driver from using the headset when in the driver'"'"'s seat. The invention enhances safe driving practices for preventing entertainment audio from being received by the headsets located in proximity to the driver'"'"'s seat.

Claims

1. A location based audio reception zone system comprising:

a driver'"'"'s seat;

at least one passenger seat;

a first transmitter located within the vehicle for broadcasting entertainment content; and

a second transmitter for disabling at least one headset when located in proximity to the driver'"'"'s seat.

2. A location based audio reception zone system as in claim 1, wherein the first transmitter transmits radio frequency (RF) signals.

3. A location based audio reception zone system as in claim 1, wherein the second transmitter transmits a radio frequency (RF) signal.

4. A location based audio reception zone system as in claim 1, wherein the second transmitter transmits an infrared (IR) signal.

5. A location based audio reception zone system as in claim 1, wherein the first transmitter operates for use with passengers located in at least one passenger seat.

6. A location based audio reception zone system as in claim 1, wherein the second transmitter broadcasts in a predetermined perimeter around the driver'"'"'s seat.

7. A location based audio reception zone system for use in vehicle comprising:

a driver'"'"'s seat;

at least one passenger seat;

a radio frequency (RF) transmitter for transmitting entertainment content to at least one headset located in proximity to the at least one passenger seat; and

wherein the RF transmitter transmits to a predefined reception zone which excludes the driver'"'"'s seat.

8. A location based audio reception zone system as in claim 7, wherein that at least one passenger seat is located behind the driver'"'"'s seat.

9. A location based audio reception zone system as in claim 7, wherein that at least one passenger seat includes a group of at least four seats.

10. A location based audio reception zone system as in claim 7, wherein the RF transmitter may be co-located within a vehicle center console.

11. A location based audio reception zone system comprising:

a driver'"'"'s seat;

at least one passenger seat;

a first transmitter for transmitting a first radio signal including entertainment content;

a second transmitter;

a directional antenna is connected to the second transmitter for directing a second transmitted signal toward the driver'"'"'s seat; and

wherein the second transmitted signal operates to block a wireless headset from operating while positioned near the driver'"'"'s seat.

12. A location based audio reception zone system as in claim 11, wherein the first transmitter transmits a radio frequency (RF) signal.

13. A location based audio reception zone system as in claim 11, wherein the second transmitter transmits a radio frequency (RF) signal.

14. A location based audio reception zone system as in claim 11, wherein the second transmitter transmits an infrared (IR) signal.

15. A location based audio reception zone system comprising:

a driver'"'"'s seat;

at least one passenger seat;

at least one first transmitter for transmitting a first signal including entertainment content to a headset located near the at least one passenger seat;

a second transmitter for transmitting a second signal using a loop antenna to a headset located near the driver'"'"'s seat; and

wherein the second transmitter operates to disable the headset located near the driver'"'"'s seat.

16. A location based audio reception zone system as in claim 15, wherein the loop antenna is located in the vehicle headliner.

17. A location based audio reception zone system as in claim 15, wherein the loop antenna is located above the driver'"'"'s seat.

18. A location based audio reception zone system as in claim 15, wherein the loop antenna is substantially rectangular in shape.

19. A location based audio reception zone system as in claim 15, wherein the first transmitter transmits a radio frequency (RF) signal.

20. A location based audio reception zone system as in claim 15, wherein the second transmitter transmits a radio frequency (RF) signal.
