ABSTRACT:
The invention concerns a method whereby not only the relative speed of the body and axle but also a dashpot's farthest-in and farthest-out positions can be measured without using complicated and expensive sensors. Relative speed is detected with a known combination of sensor coil and permanent magnet. The induced voltage at the midsection of the coil is proportional to relative speed. The voltage induced as the end of the coil is traveled by is exploited as a signal representing the dashpot's farthest-in and farthest-out positions.
