Abstract

Claims (67)

1. A method of using a sensor, the method comprising:

receiving, using the sensor, a transceiver identification (ID) from a transceiver, wherein the transceiver ID identifies the transceiver;

determining, using the sensor, whether the received transceiver ID is a new transceiver ID;

if the received transceiver ID is determined to be a new transceiver ID, storing, using the sensor, the received transceiver ID in a nonvolatile storage medium of the sensor; and

if the received transceiver ID is determined to be a new transceiver ID, conveying, using the sensor, measurement information stored in the nonvolatile storage medium to the transceiver.

2. The method of claim 1 , wherein determining whether the received transceiver ID is a new transceiver ID comprises determining whether the received transceiver ID matches a transceiver ID previously stored to the nonvolatile storage medium of the sensor.

3. The method of claim 1 , wherein the sensor conveys the measurement information stored in the nonvolatile storage medium to the transceiver only if the received transceiver ID is determined to be a new transceiver ID.
