activated safety device operates, for example controlling the speed at which an
airbag is inflated or the amount of seat belt slack which is to be taken up by a
pretensioner. Thus, the seat occupant sensing system disclosed herein may
determine the presence or absence of an object or person on a seat cushion,
and the weight of the person or object on a seat cushion and based upon those
determinations may activate one or more safety devices, and/or the manner in
which an activated safety device should operate.

Harris' invention is directed to a weighing device for logging trucks or the like.
Figure 1 shows a logging truck 10 provided with four separate sensors or strain gage
assemblies 20, 21, 22 and 23. As shown in Figure 6, the output electrical leads from
the four strain gage assemblies are connected to a sensitivity and zero adjust circuit 25
whose output leads to an indicator 26 which can provide to the driver an indication of
the total weight on all four strain gage assemblies.
Each strain gage assembly is mounted between a bolster assembly 30 and the
main frame 32. Each strain gage assembly includes a bolster plate 30A, a support plate
33A and a resilient block 40 positioned between the bolster plate 30A and the support
plate 33A. The bolster plate 30A is connected to the bolster assembly 30 and the
support plate 33A is connected to the main frame 32. The resilient material allows the
block 40 "to flex freely so that the beams thereof always bend in the same way with
applied force, thereby improving system accuracy." Strain gages 60, 61, 62 and 63 are
