Abstract

A enhanced vehicle key and a method for voice activation, the method may include supplying power to a low power trigger sensor of a enhanced vehicle key, by a power source of the enhanced vehicle key; wherein the supplying of power is preceded by powering the enhanced vehicle key while a part of the enhanced vehicle key is positioned within an ignition switch of a vehicle; detecting, by the low power trigger sensor, a voice trigger; awakening, following the detection, a processor of the enhanced vehicle key; searching, by the processor, for a voice command; and when finding the voice command then executing the voice command.

First claim

We claim:

1. A method for voice activation, the method comprises: supplying power to a low power trigger sensor of an enhanced vehicle key, by a power source of the enhanced vehicle key; wherein the supplying of power is preceded by powering the enhanced vehicle key while a part of the enhanced vehicle key is positioned within an ignition switch of a vehicle; detecting, by the low power trigger sensor, a voice trigger; awakening, following the detection, a processor of the enhanced vehicle key; searching, by the processor, for a voice command; and when finding the voice command then executing the voice command.

2. The method according to claim 1 wherein the executing of the voice command comprises requesting, by the enhanced vehicle key, the vehicle to generate a vehicle location indication that is indicative of a location of the vehicle.

3. The method according to claim 1 wherein the executing of the voice command comprises generating, by the enhanced vehicle key, a key location indication that is indicative of a location of the enhanced vehicle key.

4. The method according to claim 1 wherein the executing of the voice command comprises determining, by the enhanced vehicle key, whether a baby is present in the vehicle.

5. The method according to claim 1 wherein the executing of the voice command comprises determining, by the enhanced vehicle key, an occurrence of an accident and reporting the occurrence of the accident.

6. The method according to claim 1 wherein the executing of the voice command comprises determining, by the enhanced vehicle key, an occurrence of an event.

7. The method according to claim 6 wherein the event is selected out of a broken glass, a vehicle engine activation, a vehicle engine deactivation.

8. The method according to claim 6 wherein the determining is preceded by receiving sensed information from a sensor located outside the enhanced vehicle key, wherein the determining is based on the sensed information.

9. The method according to claim 6 comprising reporting the occurrence of the event.

10. The method according to claim 1 wherein the execution of the voice command comprises receiving a message and recording the message;
detecting, by the low power trigger sensor, another voice trigger;
awakening, following the detection of the other voice trigger, the processor;
searching, by the processor, for another voice command; and
when finding the other voice command then executing the other voice command; wherein the other voice command is for playing the recorded message; and wherein the executing comprises playing the recorded message.

11. The method according to claim 1 comprising applying, by the processor, one or more pre-processing voice algorithms, on audio signals detected by a microphone of the enhanced vehicle key.

12. An enhanced vehicle key, comprising:
a housing;
a power source;
a processor;
a low power trigger sensor that is configured to detect a voice trigger and to participate in an awakening, following the detection, the processor;
wherein the processor is configured to search for a voice command and to participate in an execution of a voice command when finding the voice command.

13. The enhanced vehicle key according to claim 12 that is configured to execute the voice command by requesting, by the enhanced vehicle key, the vehicle to generate a vehicle location indication that is indicative of a location of the vehicle.

14. The enhanced vehicle key according to claim 12 that is configured to execute the voice command by generating a key location indication that is indicative of a location of the enhanced vehicle key.

15. The enhanced vehicle key according to claim 12 that is configured to execute the voice command by determining whether a baby is present in the vehicle.

16. The enhanced vehicle key according to claim 12 that is configured to execute the voice command by determining an occurrence of an accident and reporting the occurrence of the accident.

17. The enhanced vehicle key according to claim 12 that is configured to execute the voice command by determining an occurrence of an event.

18. The enhanced vehicle key according to claim 17 wherein the event is selected out of a broken glass, a vehicle engine activation, a vehicle engine deactivation.

19. The enhanced vehicle key according to claim 17 that is configured to receive sensed information from a sensor located outside the enhanced vehicle key, wherein the determining is based on the sensed information.

20. The enhanced vehicle key according to claim 17 that is configured to report the occurrence of the event.

21. The enhanced vehicle key according to claim 12 that is configured to:
receive a message and recording the message;
detect, by the low power trigger sensor, another voice trigger;
awaken, following the detection of the other voice trigger, the processor;
search, by the processor, for another voice command; and
when finding the other voice command then execute the other voice command; wherein when the other voice command is for playing the recorded message then playing the recorded message.

22. The enhanced vehicle key according to claim 12 wherein the processor is configured to apply one or more pre-processing voice algorithms, on audio signals detected by a microphone of the enhanced vehicle key.
