Steve Rhoades, of MMS, wrote unique code that links the Vitals Signs data and GPS location and stores this data in an ASCII log file.SRL research- ers installed the equipment in a Caterpillar 793 haul truck.The result was a working prototype.Figures 1 and 2 show the instrument installation in the truck.Discussion From 8 : 30 pm on Sept. 14, 1998 until 6 : 50 am on Sept. 15 1998, 899 jolts above a threshold of 2 g (1 g is the acceleration of gravity.It is either 9.81 m/s2 or 32.17 ft / s2.) were measured on the test truck.Some sections of the haulage road produced most of the events, while.
