Apparatus and method for determining location and tracking coordinates of a tracking device
DC CAFCFirst Claim
1. A method to control power usage comprising:
- measuring a receive communication signal level by primary location tracking circuitry of an electronic tracking device communicated by a primary location tracking system;
reducing applied power level to the primary location tracking circuitry in response to measurement of a receive communication signal level less than a first signal level;
increasing applied power level to supplemental location tracking circuitry response to measurement of the receive communication signal less than the first signal level;
determining differential positional measurements based in part on acceleration measurements of supplemental location tracking circuitry associated with a secondary location tracking system; and
determining positional coordinates of electronic tracking device responsive to a known reference coordinate values and the differential positional measurements.
