Abstract
A hands-free towel dispenser is provided which utilizes an active sensing system, preferably an infra-red system, for detecting when a dispense of toweling should occur. The control for the dispenser is designed for low power use, thereby allowing the dispenser to be battery powered. The dispenser can also be powered by a solar panel, either in addition to or in place of, the batteries. Thus, the dispenser can be used in all lighting conditions. In addition, the dispenser is microprocessor controlled, thereby reducing costs and adding flexibility and functionality.
