A weight measurement system for automatically calibrating weight sensors installed on a motor vehicle seat. The system performs a calibrate operation whenever a valid weight measurement window is found. A valid weight measurement window is defined by the seat being empty, an associated door being open and an associated seat buckle being unlatched. The system operates in a factory install mode to establish a reference zero set value and in a diagnostic mode to establish a temporary zero set value that reflects drift of the weight sensors. The temporary zero set value is used by a weight management program to control occupant restraint devices. The weight sensor has an integral body with two lands connected by an elastomeric beam. The elastomeric beam has a pair of opposed surfaces that define a region of minimum thickness and one or more regions of maximum thickness. A resistive strain gauge element is disposed on the region of minimum thickness. The system measures changes in the resistance of the weight sensor caused by weight of the seat.

The candidate points are considered and refined using code phase measurements from a set of GPS satellites. The candidate point having the lowest residuals or expected to measured code phases is chosen as the location of the mobile terminal. The measurements can be refined to account for various sources of error including measurement bias, relative motion and timing errors. 0; US-5059158, 19911000, Bellio et al.; US-5967937, 19991000, Matsuo, 475/297
