Abstract: A device for preventing a human body from being jammed by using a change in capacitance, includes: a sensor unit which detects a change in capacitance corresponding to a gap between an external conductor pressed by a human body approaching a driven object and an internal conductor; a signal processing unit which compares a detection signal of the sensor unit with a reference value and outputs a jamming occurrence signal indicating the human body being jammed in the driven object; a motor driving unit which drives a motor to move the driven object; and a control unit which controls the motor driving unit to stop or move the driven object in the opposite direction when the jamming occurrence signal is received from the signal processing unit, thereby preventing a safety accident caused by the human body being jammed.

Abstract: A non-contact-type pinch prevention device suppressing the distortion of reception signals, caused by noise around an anti-pinch strip, to increase the reliability of a sensing operation for detecting a human body comprises: an anti-pinch strip which includes first and second lead wires buried in a strip body to be spaced from each other, and which allows the first lead wire to receive and output a sensing signal radiated through the second lead wire; a sensor board, which is connected to the first and second lead wires of the anti-pinch strip, generates the sensing signal in the second lead wire, and determines whether the human body is detected, according to the signal received by the first lead wire; and a control unit for performing a control operation corresponding to a body pinch situation according to a determination signal of the sensor board.
