ABSTRACT:
An automatic dispenser for dispensing lengths of paper for use as hand towels, includes an IR sensor system for detecting a user. The sensor system scans at a first scanning rate and also at a second higher scanning rate. When the sensor system detects a user, it changes the scanning rate from the first to the second rate. The dispenser aims at reducing power consumption while providing improved reaction time when required to dispense paper.
