  • Optical element driving mechanism having movable portion for holding lens
    Patent number: 11982866
    Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

  • VITAL-SIGN SENSORS
    Publication number: 20240023843
    Abstract: A vital-sign sensor is provided. The vital-sign sensor includes an output/input port, a driving/conversion circuit, a detection circuit, and a controller. The output/input port includes a detection pin. The driving/conversion circuit is coupled to the output/input port and controlled by a control signal. The detection circuit includes an input node coupled to the detection pin. The detection circuit generates a detection signal according to a detection voltage at the input node. In response to the output/input port connecting a sensing probe, the detection voltage has a first voltage value, and the controller detects a type of the sensing probe according to the detection signal corresponding to the first voltage value. The controller generates the control signal according to the determined type. The driving/conversion circuit generates a driving signal according to the control signal to drive the sensing probe.

  • CHARGING DEVICE AND METHOD THEREOF
    Publication number: 20210305822
    Abstract: A charging device and method thereof is provided. The charging device is connected to a power supply device. The charging device includes a detection pin, a switch module, and a control circuit. The detection pin has a voltage level which reflects whether the charging device is connected to an electronic device. The control circuit is connected to the detection point and the switch module. According to the voltage level of the detection pin, the control module controls the switch module to be in an open state if the control circuit determines that the charging device is not connected to the electronic device.
