Remote control with reduced responsiveness to interrupted actuating signals

摘要

A wireless remote control system has a transducer coupled to a sampling frequency counter to distinguish among various actuating signals. A comparator compares present and immediately preceding measurements and a confidence counter counts the number of identical comparisons and is reset for non-identical comparisons. A decoder which is disabled until the confidence counter reaches a predetermined count is coupled to utilization means to actuate the selected function. Logic means contain a clock controlled interval counter which is activated only after the confidence counter reaches the predetermined count for establishing a timing interval. During the interval logic means render the confidence counter unresponsive to the comparator thereby maintaining actuation of selected functions. Logic means also force a preset count into the interval counter to prevent establishing the timing interval for other functions.
