  • Publication number: 20170351638
    Abstract: A module comprising a USB Type-C receptacle, a USB Type-C plug and a logic unit is disclosed. A power pin of the receptacle is connected with another power pin of the plug via a switch. A CC pin of the receptacle is connected to ground through a pull-down resistance. Another CC pin of the plug is connected to the logic unit through a pull-up resistance. The module connects with a power source device being a power sink-role in order to receive a source capability of the power source device, then turns on the switch and transforms itself to a power source-role. The module connects to a DRP device afterward being the power source-role to act for the power source device and perform a USB PD communication with the DRP device.

  • Patent number: 9780286
    Abstract: A nebulizing driving apparatus is used to drive a piezoelectric material of a nebulizing module. The nebulizing driving apparatus includes a driving circuit, a control circuit and a feedback circuit. The feedback circuit detects an electrical data fed back from the piezoelectric material and sends the electrical data to the control circuit when the control circuit is configured to control the driving circuit to drive the piezoelectric material with a driving frequency. According to the electrical data, the control circuit is configured to control the driving circuit to drive the piezoelectric material with a working frequency.

  • Publication number: 20170054310
    Abstract: A USB charging method adopted by an electronic source device and an electronic sink device electrically connected thereto through USB interface is present. The method comprises following steps: receiving a Discover Identity ACK from the sink device after connection; determining if the sink device is recorded in a protect list according to the Discover Identity ACK; adjusting voltage/current combinations which is to provide to the sink device according to a best working voltage of the sink device if the sink device is recorded in the protect list; transmitting the adjusted voltage/current combinations to the sink device.
