Title:
DEVICE FOR PREVENTING HUMAN BODY FROM BEING JAMMED USING CHANGE IN CAPACITANCE
Document Type and Number:
WIPO Patent Application WO/2022/055157
Kind Code:
A1
Abstract:
The present invention relates to a device for preventing a human body from being jammed by using a change in capacitance that can prevent a safety accident caused by a human body being jammed by using a sensor unit for detecting a change in capacitance, the device comprising: 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.
