Apparatus for detecting and storing data representative of shock imparted to vehicle during travel
First Claim
1. An apparatus for detecting shocks imparted to a motor vehicle during travel thereof over a transfer path and for storing data representative of the shocks, said apparatus comprising:
- a storage unit including a memory;
a global positioning system operable to determine a position of the vehicle along said path;
a shock sensor for detecting shocks imparted to the vehicle during travel thereof over the path and for generating shock data representative of magnitude of the shocks;
means for, when said shock data exceeds a predetermined minimum value indicative of a detected shock of not less than a predetermined magnitude, operating said global positioning system to determine the position of the vehicle along the path when said detected shock occurred and generating position data representative thereof;
a timer in said storage unit to generate time data representative of the time when said detected shock occurred; and
means for sending said shock data exceeding said predetermined minimum value, said position data and said time data to said memory.

Abstract
A shock generating position storage unit includes an acceleration sensor for detecting an impulsive wave or shock applied to a vehicle during transportation thereof, a storage unit for storing data representative of such impulsive wave or shock, and a global positioning system (GPS) for determining a position of the vehicle along a travel path based on a radio wave received from an artificial satellite. Data of the travel position at a time when data of the impulsive wave or shock detected by the acceleration sensor exceeds a predetermined minimum value is sent to the storage unit from the GPS at the same time the impulsive wave or shock data is sent thereto.
