Abstract
Abstract A sensing system connects to a switch display encoder apparatus and monitors the rotational speed of a plurality of encoders in all directions independently and responds to rate-aided commands issued by the user or by a Central Processing Unit (CPU). As the encoders spin in any direction, a quadrature output signal from each encoder is sent to the sensing system which processes the raw quadrature data and transmits, via an output controller, a rate-aided signal to the CPU. The CPU can interactively issue commands to the system which changes the speed thresholds and rate-aided output signals. The user can preset and interactively change speed thresholds and rate-aided outputs via switches mounted on the apparatus. Parameters settings are transmitted to the sensing system and to an external CPU. The apparatus contains numeric displays that indicate switch selected or CPU instructed speed thresholds, rate-aid multipliers, or rate-aid dividers.
