Patent number: 11888346Abstract: The present disclosure provides a compact bionic eye device based on a two-degree-of-freedom electromagnetically-driven rotating mechanism, which can be used as a vision sensor of bionic robots such as humanoid robots. The compact bionic eye device includes a rotor, stator cores, windings, an angular displacement camera, a spherical hinge pressing block, a stator connector, a camera, a spherical hinge, a camera connector, a rotor connector and an outer spherical shell. According to the compact bionic eye device of the present disclosure, the rotor is driven to achieve limited rotation with pitching and yawing degrees of freedom by regulating a current of the windings of four stators. By adopting a two-degree-of-freedom of electromagnetically-driven rotating mechanism which is compact in structure, the bionic eye device of the present disclosure can achieve a human eye size, and provides important foundation for practical application of bionic eyes in humanoid robots.Type: GrantFiled: June 12, 2020Date of Patent: January 30, 2024Assignee: BEIHANG UNIVERSITYInventors: Tong Wei, Zhongwen Shan

Patent number: 9246379Abstract: Aspects of the disclosure provide a circuit that can include a depletion mode transistor coupled to a power source and a current path coupled with the depletion mode transistor in series to provide a current to charge a capacitor. Further, a gate terminal of the depletion mode transistor is coupled to a clamping path that includes a diode and a switch that connected in series. The clamping path clamps the voltage at the gate terminal of the depletion mode transistor to the capacitor. The clamping and the current paths respectively have a first resistance during a first stage, such as when the circuit initially receives power, and have a second resistance during a second stage when the capacitor is charged to have a predetermined voltage level.Type: GrantFiled: October 14, 2013Date of Patent: January 26, 2016Assignee: Marvell International Ltd.Inventors: Siew Yong Chui, Tong Wei Lian
