<p>A powered dispenser for dispensing individual sheet segments from a continuous roll of sheet material. The sheet material (17) has spaced tear lines (19). The dispenser (1) has a releasable powered drive mechanism (47) and a power supply system (95, 97). There is a pair of towel sensors (111, 113) to sense the presence of sheet material (17) in a discharge chute (41). The sensors (111, 113) are coupled with a microprocessor (115) to detect a leading edge of the material (17). Utilizing signals from the sensors (111, 113) and a capacitive sensing system (C10, C12), the system senses the presence of a user.</p> |
