  • Patent number: 11994923
    Abstract: A dongle coupled between a power supplying device for supplying power and a power receiving device for receiving power includes a downstream facing port (DFP), an upstream facing port (UFP) and a controller. The controller is arranged to control deliveries of the power and messages between the power supplying device and the power receiving device. In response to a first power request message received from the power receiving device, the controller is arranged to determine whether a power type request by the power receiving device is Programmable Power Supply (PPS) according to the first power request message. When determining that the power type request by the power receiving device is PPS, the controller is arranged to start first waiting timer, and when the first waiting timer expires, the controller is arranged to send a request accept message to the power receiving device through the UFP.

  • Publication number: 20120274263
    Abstract: A system for power management electrically connected to a solar cell is provided. The system for power management includes a photo-sensor, a controller electrically connected to the photo-sensor, and a power manager. The photo-sensor detects an illumination (illuminance or irradiance) of an environment where the solar cell is located. A look-up table of illumination vs. maximum output power is built in the controller, wherein a corresponding maximum output power is determined by the controller according to the illumination detected by the photo-sensor. The power manager is electrically connected to the controller and the solar cell. The power manager controls the output current of the solar cell so as to equalize an output power of solar cell and the corresponding maximum output power. A method for power management is also provided.
