  • Patent number: 8754552
    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.

  • Patent number: 8079537
    Abstract: 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.

  • Publication number: 20100243775
    Abstract: The present invention relates to providing active protection through a safe structure of a paper shredder. It comprises a paper shredder upper cover and a paper shredder plate disposed on the paper shredder upper cover. Different from prior art paper shredders, which are provided with independent safe switches, the paper shredder plate of the present invention, is configured with a touch structure and a safe power supply switch. When closed, the paper shredder plate prevents users from accidentally touching the shredding blade, and the like. Inside the paper shredder, it starts the paper shredder and guarantees the paper shredder's normal operation on the one hand, and prevents forced feeding of non-expected items on the other hand. In the later case, the structure disposed on the inner surface of the paper shredder plate provides dual protection and is capable of stopping the paper shredding from working, whereby the safety of users is enhanced.
