Accelerometer gauge using solid state accelerometers

An acceleration gauge using solid state accelerometers for a vehicle, comprising:

• a first solid state accelerometer mounted substantially along one axis of the vehicle and responsive to the vehicle movement along said one axis to generate a first acceleration signal;
• a second solid state accelerometer mounted substantially along a second axis of the vehicle and responsive to the vehicle movement along said second axis to generate a second acceleration signal;
• a third solid state accelerometer mounted substantially along a third axis of the vehicle and responsive to the vehicle movement along said third axis to generate a third acceleration signal;
• a housing;
• a microcomputer located in said housing and having an input for receiving said acceleration signals, a memory, an algorithm stored in said memory, said algorithm programmed to align each of the first, second and third accelerometers accurately along said axes regardless of their initial positioning, calculation means responsive to said algorithm and said acceleration signals for generating control signals;
• power driver means responsive to said control signals for generating driver signals;
• display means responsive to said driver signals for generating alpha-numeric displays giving real-time acceleration values of the vehicle movement in all three axes in human readable form;
• a digital control unit responsive to said driver signals for generating digital acceleration signals and a digital gauge member responsive to said digital acceleration signals for displaying acceleration values sensed by said accelerometers;
• and
• a servo control unit responsive to said driver signals, a servo motor electrically connected to said servo control unit and said display means being at least one analog gauge having a needle connected to said servo control unit for displaying acceleration values sensed by said accelerometers on said display means.
