Abstract
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.
