1. A power supply for an accelerometer comprising:

  • a power supply housing;

    an accelerometer battery power supply in said power supply housing, which provides sufficient power for an accelerometer;

    output means, for electrically and mechanically connecting said accelerometer battery power supply to an accelerometer external to said power supply housing, and for receiving accelerometer signals from said accelerometer external to said power supply housing;

    input means, for electrically and mechanically coupling said accelerometer battery power supply to a portable computer external to said power supply housing, for receiving a control signal from the portable computer external said power supply housing and for providing said accelerometer signals to the portable computer external to said power supply housing;

    said accelerometer battery power supply being responsive to said control signal to activate said accelerometer battery power supply to supply power for an accelerometer external to said power supply housing to said output means so that the accelerometer external to the power supply housing is powered by the accelerometer battery power supply instead of by said portable computer external to said power supply housing.
