  • Publication number: 20230369927
    Abstract: An electromagnetic rotating device is provided. The electromagnetic rotating device includes a base, a pole disc, and a plurality of pole control units. Magnetic elements of the pole disc are arranged on a disc body. A second circular orbit of the pole disc is disposed on a lower surface of the disc body. The second circular orbit is configured to be slidably combined on a first circular orbit of the base. The pole control units are arranged on the base and configured to magnetically drive the magnetic elements to move, so that the pole disc rotates relative to the base.

  • Patent number: 8218279
    Abstract: An electronic device assigns power to USB ports dynamically. A total current detection circuit transmits driving voltage signals to the USB ports, and detects whether a total current provided to the USB ports exceeds a rated total current and output a total current detection signal. A plurality of short-circuit detection circuits detects whether USB devices connected to the corresponding USB ports are shorted and to output a short-circuit detection signal. A plurality of relay circuits switch connection between the USB ports and the power circuit. A USB controller outputs a control signal according to the total current detection signal and the short-circuit detection signal and directs the relay circuits to switch connection between the corresponding USB ports and the power circuit on and off.
