Unformatted text preview: The design is to compose of a Kistler #912 quartz load cell installed in a large weighing scale. Attached to the load cell is a Kistler #5004 charge amplifier which relays the signal to a computer and oscilloscope which can be seen in Fig. 1. The method for checking the truck would be driving the truck onto the scales that contain the load cells. The driver and all other passengers would then be required to exit the vehicle and the engine must be shut down. A certain grace period must be allowed for the vehicle to come to steady state (i.e. fluids stop moving in the engine) before a scan can be taken. Once at steady state a computer equipped with an AquireNScan2File.vi will give a visual output of the voltage graph showing any unusual motions, heartbeats, and forces in the truck. Any irregualarties of the system would then be grounds for a manual search of the vehicle by the U.S. Border Patrol. Fig 1. Proposed design of instrument setup....
