Publication number: 20060273806Abstract: An electrical characteristic in an operator-sensing circuit having a microcontroller that commands a charge sensor to send a sensor charge signal to a capacitive sensing element. The charge sensor outputs a corresponding raw data signal to the microcontroller that in turn sends a signal that disables the motor of a unit power equipment upon the absence of an operator's hand on a hand-gripping surface of the equipment. Capacitive means for operating within a predetermined charge range that includes preselected values that designate hands-off and hands-on conditions on the hand-gripping surface. The capacitor charge range is effective to distinguish between the presence of an operator's hand and foreign material on the gripping surface for avoiding a false hands-on-signal.Type: ApplicationFiled: August 15, 2006Publication date: December 7, 2006Applicant: Gustav Magenwirth GmbH & Co.
