Patent number: 12209888Abstract: A reading device for capacitive sensing element comprises a differential capacitive sensing element, a modulator, a charge-voltage conversion circuit, a phase adjustment circuit, a demodulator and a low-pass filter. The modulator outputs a modulation signal to the common node of the capacitive sensing element and modulates the output signal of the capacitive sensing element. The two input terminals of the charge-to-voltage conversion circuit are connected to two non-common nodes of the capacitive sensing element. The charge-to-voltage converter read the output charge of the capacitive sensing element and convert it into a voltage signal. The modulator generates a demodulation signal through the phase adjustment circuit. The demodulator receives the demodulation signal from the phase adjustment circuit and demodulates the output of the charge-to-voltage conversion circuit. The low-pass filter is connected to the output of the demodulator for filtering the demodulated voltage signal to output the read signal.Type: GrantFiled: January 13, 2023Date of Patent: January 28, 2025Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Lu-Pu Liao, Yu-Sheng Lin, Liang-Ying Liu, Chin-Fu Kuo

Patent number: 8587440Abstract: A method and system for monitoring a driver is disclosed. Firstly, an inner cabin image of a vehicle's cabin is continuously captured. Next, a face detection of a driver for the inner cabin image is performed to obtain a face detection result. Next, the inner cabin image and the face detection result corresponding to the inner cabin image are stored. When the system observes that either the face of the driver is not detected or the face is not shown within a reasonable face region of at least two continuous inner cabin images according to each face detection result, the system outputs a warning signal to alert the driver. The invention determines a driving state of a driver in a cabin with a method of analyzing a position of a face or a head and using an image extractor having large capture range and a low resolution.Type: GrantFiled: February 11, 2010Date of Patent: November 19, 2013Assignee: Automotive Research & Test CenterInventors: Ming-Cong Weng, Yu-Sheng Liao, Yu-Song Chen

Patent number: 8552873Abstract: In a method and system for detecting a driving state of a driver in a vehicle, a face recognition standard corresponding to an environmental condition within the vehicle is established based on a series of image frames generated by capturing consecutively images of the driver upon movement of the vehicle. Upon detection of a variance in the environmental condition during movement of vehicle, the face recognition standard is updated with a corrected face recognition standard corresponding to the environmental condition with the variance. It is determined based on the corrected face recognition standard and the image frames whether the driving state of the driver is a dangerous state, where the driver's face does not face a front windshield of the vehicle or where the driver's face faces the front windshield of the vehicle but one of the driver's eyes is closed.Type: GrantFiled: December 28, 2010Date of Patent: October 8, 2013Assignee: Automotive Research & Testing CenterInventors: Yu-Sheng Liao, Chia-Tseng Chen, Yu-Sung Chen
