PCT No. PCT/GB93/02495 Sec. 371 Date Jun. 21, 1995 Sec. 102(e) Date Jun. 21, 1995 PCT Filed Dec. 6, 1993 PCT Pub. No. WO94/14577 PCT Pub. Date Jul. 7, 1994.An angular motion detector, of particular relevance in breakaway point detection, includes a flywheel rotatably mounted on a spindle. The flywheel is provided with one or more indicia, which are detectable by a sensor situated on the object whose angular motion is to be analyzed. The sensor is connected to a microprocessor. In use the flywheel is rotated manually about the spindle so that the regular detection of the indicia by the sensor causes a train of pulses to be sent to the microprocessor. Angular movement of the object, and consequently of the sensor, causes a disruption of the pulse train which can be analyzed to provide information relating to the time of first movement and the magnitude of the angle moved.
