MOTION DETECTOR FOR WEIGHING APPARATUS

摘要

A detector for detecting the change in the number of pulses in serially applied pulse streams by memorizing a function representing the preceding one of the two pulse stream and by comparing the memorized function with a corresponding function of the subsequentially occurring one of the two pulse streams. This detector is, among other things, applicable to sense relatively small movements of a load-receiving structure (such as a weigh hopper or platform) in a weighing system.
