1. A method of transmitting data and control information contained in a plurality of information packages to an optical receiver in an optical locator system, comprising the following steps:

  • providing a motion detectable TAG having a memory and a serial data interface storing said data in said TAG'"'"'s memory;

    forming at least one information packet containing selected data and identifying information for the optical locator system;

    selecting motion count defining the number of allowable motion detection;

    activating a sleep mode of said TAG, thereby reducing the normal electrical power consumption of said TAG;

    reactivating said sleep mode of said TAG when motion is detected by said motion detector, thereby returning the power level of said TAG to normal;

    selecting an interval count defining the number of transmissions to the optical locator system;

    forming an uplink information package containing said plurality of information packets, and said transmission interval count;

    transmitting said uplink information package to said optical locator system;

    decrementing said motion count, thereby reducing the definable number of allowable motion detection;

    incrementing said transmission interval count;

    forming a second uplink information package containing said plurality of information packets and said incremented transmission interval count;

    retransmitting said second uplink package containing said incremented transmission interval count and said plurality of information packets when said decremented motion count is true; and

    activating the sleep mode of said TAG when said decremented motion count is false, thereby reducing electrical power consumption by said TAG.
