Abstract
A fluid dispenser which discharges a predetermined amount of fluid upon actuation of a actuator includes a counter and at least two timers for use by users of the device. The apparatus further includes a switch coupled to the actuator wherein the switch generates a use signal. An operating circuit is carried by the dispenser and provides a processor which receives the use signal and increments or decrements a counter by one. Additionally, the processor generates a flag signal to indicate which of the timers is in use. Each timer has associated therewith a distinct sensor output such as a sound or light to indicate to the user the start of a washing cycle and completion thereof. In the event more than two users are present, the sensor output is not provided. However, a counting event is still recognized. Of course, multiple users of the device or sensor outputs could be provided if desired.
