  • Patent number: 11036670
    Abstract: A electronic device includes a USB Type-C interface, a switching circuit, a first signal path, and a second signal path. The USB Type-C interface is configured to connect to a USB Type-C device. The switching circuit is connected to the USB Type-C interface, the first signal path, and the second signal path. When the USB Type-C interface is connected to the USB Type-C device, the first signal path is connected to the USB Type-C interface through the switching circuit, and a level of a first pin of the USB Type-C interface is a first level. When the USB Type-C interface is disconnected from the USB Type-C device, the second signal path is connected to the USB Type-C interface through the switching circuit, and a level of the first pin is a second level. The first level is greater than the second level.

  • Patent number: 10954180
    Abstract: The present disclosure relates to a process for acid-catalyzed decomposition of aryl ?-hydroperoxide with a continuous flow tubular reactor. The process is a novel process performed in a tubular reactor, taking the aryl ?-hydroperoxide such as cumene hydroperoxide (CHP) as a raw material and taking acids as a catalyst, performing acid-catalyzed decomposition of the aryl ?-hydroperoxide solution in a short reaction time ranging from tens of seconds to several minutes, thereby obtaining the phenols; wherein an inert component may be filled in the reactor, so that the effects of heat transmission and mass transfer can be enhanced. The aryl ?-hydroperoxide and acid are respectively introduced by a metering pump into a mixing module to be mixed, and then enter the tubular reactor to be reacted so as to produce the products such as phenols.
