1. A system for use with an accelerometer to determine a frame of reference, for subsequent use in assessing or monitoring a status of a vehicle or other equipment, or operator thereof, comprising:

  • a data collection and assessment system comprising one or more data collection devices, including one or more accelerometers, that collects information from the one or more accelerometers as the vehicle or other equipment is moving; and

    a frame determination module which samples or otherwise receives accelerometer data over a period of time, and also information from one or more other on-board devices, and uses this information to determine a rotation matrix that reflects the skew between the system'"'"'s orientation and understanding of direction, and the vehicle'"'"'s true orientation or direction in three-dimensions, and to determine a frame of reference for use in subsequently characterizing motions of the vehicle or other equipment in three dimensions.
