Abstract

Techniques that provide relatively low cost and complexity remote sensing capability are disclosed. The sensors can be easily deployed and monitored by a single operator, with minimal opportunity for human error, and without the need for a visual display. During deployment, the sensor is adapted to record a message including a verbal description of the location. Other useful information, such as the operator'"'"'s name and sensor type may also be included. The voice locator message is transmitted in response to the sensor triggering, thereby allowing the operator to hear the location of the triggered sensor. Additional device functionality may include sensor signal analysis (e.g., confidence testing) and a power conservation. The devices have numerous applications (e.g., military and SWAT operations), and can be adapted to detect intrusion, perimeter breach, movement, vehicles, and other detectable events.

Claims

1. A remote sensor device comprising:

a sensor module adapted to sense one or more event types;

a storage module adapted to store a voice message including a deployment location description of the device; and

a transmitter adapted to wirelessly transmit the voice message in response to the sensor being triggered.

2. The device of claim 1 wherein the device is deployed by an operator, and the voice message further includes the operator'"'"'s name.

3. The device of claim 1 further comprising:

a processor operatively coupled to the transmitter and the storage module, and adapted to control operation of the device.

4. The device of claim 3 wherein the processor can command the transmitter to transmit in analog and digital.

5. The device of claim 3 wherein the processor is further adapted to carry out a power conservation mode where one or more power consuming components of the device are commanded to a sleep or low power mode during periods of inactivity.

6. The device of claim 3 further comprising:

a microphone operatively coupled to an amplifier thereby enabling the voice message to be captured and converted into an electronic signal; and

a switch operatively coupled to the processor, and adapted to enable a voice message recording session.

7. The device of claim 1 further comprising:

a microphone operatively coupled to an amplifier thereby enabling real-time ambient sound to be captured and converted into an electronic signal;

wherein the transmitter is further adapted to wirelessly transmit the electronic signal.

8. The device of claim 1 further comprising:

a digitizer adapted to receive a captured voice message and to convert it to a digital signal for storage in the storage module.

9. The device of claim 1 further comprising:

a processor that is adapted to determine a confidence level associated with a sensor signal provided by the sensor module.

10. The device of claim 9 wherein the sensor signal is compared to pre-defined reference to determine its confidence level.

11. The device of claim 9 wherein in response to the sensor signal having an acceptable confidence level, the processor is further adapted to command transmission of the stored voice message in at least one of analog or digital using the transmitter.

12. The device of claim 9 wherein the processor is further adapted to command transmission of a pre-stored message indicative of the confidence level.

13. The device of claim 1 wherein the sensor module employs at least one of IR, acoustic, radar, electro-static, and seismic sensing capability.

14. A method for remotely sensing an event, the method comprising:

in response to no sensor being triggered, continuing monitoring for at least a set period of time; and

in response to determining that a sensor has been triggered, transmitting a recorded message including a verbal description of the sensor location.

15. The method of claim 14 wherein the method includes a set-up mode comprising:

receiving an activation signal to initiate the set-up mode;

enabling a voice message recording session; and

recording the message including the verbal description of the sensor location.

16. The method of claim 15 wherein an operator initiates the set-up mode, and the verbal message further includes the operator'"'"'s name.

17. The method of claim 14 wherein in response to the sensor triggering, the sensor outputs a sensor signal, the method further comprising:

transmitting one or more pre-recorded messages indicative of a confidence level associated with the sensor signal.

18. The method of claim 14 further comprising:

transmitting real-time sound from the area for a period of time relative to a sensed event.

19. A method for remotely sensing an event with a sensor configured with a voice locator message, the method comprising:

identifying a location to be monitored;

enabling a sensor voice recording session; and

announcing at least one of operator name and sensor location, thereby creating a recorded voice message for transmission when the sensor triggers.

20. The method of claim 19 wherein a number of sensors are deployed in an area, and each sensor transmits on a common channel, the method further comprising:

tuning a remote receiver to the common channel, thereby enabling a communication link between the remote receiver and the area.
