Static build up control in electronic dispensing systems
DCFirst Claim
1. A method of grounding a battery operated dispenser adapted to dispense paper from a roll of paper disposed within the dispenser, the method comprising:
- connecting a low impedance path to elements integral to the dispenser;
connecting said low impedance path to a surface contact spring adapted to directly contact a surface when said dispenser is mounted to the surface; and
discharging static electrical charge accumulated on the elements to the surface through the low impedance path and the surface contact spring.

Abstract
Apparatus for dispensing paper from rolls which feeds continuously, roll to roll, and does not require extra procedure to bring stub roll into position. The apparatus has device for holding and positioning at least first and second rolls of paper with respect to each other; device for dispensing paper from the first roll; device for dispensing paper from the first and second rolls simultaneously when the first roll reduces to a predetermined diameter of paper, device for positioning the depleted first roll for replacement without the necessity of removing the second roll; and device for dispensing from the second and replacement rolls simultaneously when the second roll reduces to a predetermined diameter of paper. The apparatus also has a proximity sensor, which senses when a hand is placed near the dispenser, and thereupon dispenses a set amount of towel. The dispenser incorporates device for dissipating static charges to a local ground.
