Title: Error measurement in navigation distance or speed sensor - involving computations using measured values of known position coordinates
Inventor: HAMMANN-KLOSS WALTER DIPL ING
IPC: G01C25/00
Filed: 1979-09-22
Abstract: A method of determining errors in sensors measuring the distance covered or speed of a vehicle with a navigation unit using the sensor output to determine the position of the vehicle enables simple reliable error measurement and/or an at least approximate correction of the errors. The position (P2) determined in a first computation process combining the sensor signal and the output of a direction sensor differs from the actual position (P1). A further computation carried out with a given speed or acceleration dependent pseudo-error results in a corresp. erroneous position (P3). These computations are performed for two or more routes between known positions. The sensor errors are determined using the known coordinates of the route end positions. The measured errors are then used for error correction.

Title: Vehicular energy re-cycling system - converts vehicle energy into stored potential energy using hinged road sections coupled to pump
IPC: F03G7/08
Filed: 1979-10-10
Abstract: The energy recycling system employs hinged sections of a road or motorway deflected by passing vehicles and coupled by rods to pumps to convert a passing vehicle's kinetic energy into stored energy. The system is located beneath the road. A vehicle travels onto the first hinged section (1,2) raised above the general level of the road which is deflected down by the vehicle. The first section is linked by a coupling mechanism (5,7,9) to a pump (10,11) and to a second hinged section (3,4). When the first section is deflected down, the pump is operated and the second section is raised. The vehicle then passes onto the second section, forcing it down and causing it to operate the pump piston a second time and to raise the first hinged section back into the original position.

Title: Selective vehicle identification system - uses multiplier and logic circuit for spectral analysis of IR from exhaust gases
Inventor: CUQ BERNARD
IPC: G01V9/00
Filed: 1979-10-12
Abstract: The remote detection system uses the exhaust gases emitted by a vehicle IC engine to produce a selective identification. The exhaust gases provide an infrared absorption spectrum which presents an instant contrast to the spectrum of the ambient air. A spectral filter provides an electric signal which is amplified and applied to one input of a comparator. The second input receives a reference signal representing the ambient air. A circuit for correcting the reference signal includes a delay acting on the comparator output in parallel with a low-pass filter which eliminates the detector pulse signal. A variable multiplier signal introduces a contrast correction function, and an adder forms the algebraic sum of the delayed voltage and the multiplied voltage to form the reference voltage signal.
