The invention is directed to a permittivity-based paper shredder control system. The touching feature is implemented through a series of electronic circuits, taking input from a conductive touch panel on the shredder feed throat, processing the signal, and through a motor driving circuit, stopping the mechanical parts of the shredder. The system has a touch detection circuit unit, which contains a bioelectricity controlled switching circuit to sense the conductive touch panel. The bioelectricity controlled switching circuit is configured to trigger a ground switching circuit in the touch detection circuit unit which outputs to a multifunction bioshield controller. The bioshield controller then takes care of the remaining protection issues. The touching device for paper shredders protects humans and other living beings including pets from injuries through automatic and real time monitoring. The complete control process is both safe and sensitive.

Permittivity-based paper shredder control system

Active protection system for a paper shredder, which includes an upper cover and a shedder plate on the upper cover. The paper shredder plate includes a touch structure, which engagingly interacts with a preferential power supply switch. When closed, the shredder plate prevents contact with the shredding blade. When opened, the shredder plate both initiates shredder normal operation, and prevents feeding of unexpected items into the shredder making accidental contact with the shredding blade. When an unexpected item contacts the safety structure, beneath the paper shredder plate, the protection system switches off the shredder power supply.
