  • Patent number: 10613295
    Abstract: The tri-axis close-loop feedback controlling module for electromagnetic lens driving device comprises a 6-pin Hall element. Two pins of the Hall element are coupled to an auto-focus module for providing a current to drive the auto-focus module to conduct auto-focusing operations along the Z-axis; while other four pins of the Hall element are coupled to a control unit. The control unit detects the X-Y axial positions of the auto-focus module relative to an OIS module and generates a control signal which is then sent to the Hall element. Therefore, the Hall element not only can provide its own feedback controlling function according to the Z-axial position of lens, but also can drive the auto-focus module based on the control signal corresponding to the X-Y axial positions of the auto-focus module, so as to achieve the goal of tri-axis close-loop feedback controlling for the electromagnetic lens driving device.

  • Patent number: 10484546
    Abstract: A doorbell conversion device includes a power input terminal, a power output terminal, two doorbell trigger terminals, a power conversion unit, and a trigger signal unit. The power conversion unit is coupled between the power input terminal and the power output terminal for generating a sensing signal in response to an electric potential of the power output terminal. While the electric potential of the power output terminal is grounded, the power input terminal and the power output terminal are disconnected. In contrast, the power input terminal and the power output terminal are connected. The trigger signal unit is coupled between the power conversion unit and the two doorbell trigger terminals for controlling the two doorbell trigger terminals to be opened or shorted based upon the sensing signal. While the electric potential of the power output terminal is grounded, the two doorbell trigger terminals are shorted. In contrast, they are opened.

  • Patent number: 10354637
    Abstract: A sound receiving device and a noise signal generating method thereof are disclosed. A linear voltage regulator module of the sound receiving device receives a power signal for converting into a first current signal. A microphone is used to receive an external audio signal. A digital modulation module receives the first current signal so as to process the external audio signal to become a digital audio signal. After the linear voltage regulator module receives a control signal, the first current signal is stopped, and the power signal is transmitted through a current limiting resistor to generate a second current signal to the digital modulation module, so that the digital modulation module generates and output a noise signal, wherein an amperage of the second current signal is less than an amperage of the first current signal and is not enough to normally drive the digital modulation module.
