Abstract: A shredder safety device having emergency stop, including: at least one sensing component provided next to a shredder opening, the sensing component being electrically connected to a conventional tactile sensing circuit and a motor driving circuit, whereby when the sensing component comes into contact with the human body (finger), signals are generated to command shutdown of the motor driving circuit through the tactile sensing circuit, resulting in motor halt thereby preventing the human body (finger) from being pulled into the shredder opening and resulting in injuries.

Abstract: A wireless local loop equipment parameter setting system and method that uses a telephone attached to wireless local loop equipment to issue a control instruction. The wireless local loop equipment receives the control instruction, translates the instruction and sets or displays the parameters accordingly. A miniature display device connected to the wireless local loop equipment through a serial transmission interface is used to display the control instruction and content of the parameters so that a user may set parameters with ease.
