User-configurable person detection system, method and apparatus

1. A person detection device for configuring a dwell time of the person detection device, comprising:

a detector for detecting a presence of a person in an area;

a memory for storing processor-executable instructions and the dwell time;

a transceiver for sending and receiving wireless signals; and

a processer coupled to the detector, the memory and the transceiver, for executing the processor-executable instructions that causes the person detection device to:

receive, by the processor via the transceiver, a new dwell time from a personal communication device;

in response to receiving the new dwell time, estimate, by the processor, a remaining battery life based on the new dwell time;

transmit, by the processor via the transceiver, the estimated remaining battery life to the personal communication device;

receive, by the processor via the transceiver, an indication from the personal communication device to use the new dwell time; and

replace, by the processor, the dwell time in the memory with the new dwell time.

2. The person detection device of claim 1 , wherein the processor-executable instructions comprise further instructions that cause the person detection device to:

determine, by the processor via the detector, the presence of the person in the area;

determine, by the processor, an elapsed time since the transceiver previously transmitted a signal indicative of the presence of a person in the area; and

when the processor determines that the elapsed time is less than the new dwell time, refrain, by the processor, from transmitting a new signal indicative of the presence of the person in the area.

3. The person detection device of claim 1 , wherein the processor-executable instructions comprise further instructions that cause the person detection device to:

determine, by the processor, an elapsed time since the transceiver previously transmitted a signal indicative of the presence of the person in the area; and

when the processor determines that the second elapsed time is greater than the new dwell time, transmit, by the processor via the transceiver, a new signal indicative of the presence of the person in the area.

4. The person detection device of claim 1 , wherein the new dwell time comprises an incremental time in which to increase or decrease the dwell time by a predetermined amount.

5. The person detection device of claim 1 , wherein the new dwell time comprises a time period.

6. The person detection device of claim 5 , wherein the processor-executable instructions comprise further instructions that cause the person detection device to:

compare, by the processor, the time period to an upper dwell time threshold stored in the memory;

determine, by the processor, that the time period exceeds the upper dwell time threshold; and

transmit, by the processor via the transceiver, an error message to the personal communication device when the processor determines that the time period exceeds the upper dwell time threshold.

7. The person detection device of claim 6 , the instructions for estimating a remaining battery life comprises instructions that causes the person detection device to:

measure, by the processor, a battery voltage of the person detection device during a transmission by processor via the transceiver;

compare, by the processor, the battery voltage to a stored battery voltage in the memory; and

determining, by the processor, the remaining battery life as a result of comparing the battery voltage to the stored battery voltage in the memory.

8. A method, performed by a person detection device, for configuring a dwell time of the person detection device, comprising:

receiving a new dwell time from a personal communication device;

in response to receiving the new dwell time, estimating a remaining battery life based on the new dwell time;

transmitting the estimated remaining battery life to the personal communication device;

receiving an indication from the personal communication device to use the new dwell time; and

replacing the dwell time storing in a memory with the new dwell time.

9. The method of claim 8 , further comprising:

determining the presence of the person in the area;

determining an elapsed time since a signal was transmitted by the person detection device, indicative of a presence of a person in an area proximate to the person detection device; and

when the elapsed time is less than the new dwell time, refraining from transmitting a new signal indicative of the presence of the person in the area.

10. The method of claim 8 , further comprising:

determining an elapsed time since the transceiver previously transmitted a signal indicative of the presence of the person in the area; and

when the second elapsed time is greater than the new dwell time, transmitting a new signal indicative of the presence of the person in the area.

11. The method of claim 8 , wherein the new dwell time comprises an incremental time in which to increase or decrease the dwell time by a predetermined amount.

12. The method of claim 8 , wherein the new dwell time comprises a time period.

13. The method of claim 12 , further comprising:

comparing the time period to an upper dwell time threshold stored in the memory;

determining that the time period exceeds the upper dwell time threshold; and

transmitting an error message to the personal communication device when the time period exceeds the upper dwell time threshold.

14. The method of claim 13 , further comprising:

measuring a battery voltage of the person detection device during a transmission by the person detection device;

comparing the battery voltage to a stored battery voltage in a memory of the person detection device; and

determining the remaining battery life as a result of comparing the battery voltage to the stored battery voltage in the memory.
