  • Patent number: 8900012
    Abstract: An improved Universal Serial Bus (USB) connector apparatus is provided. In one embodiment, the USB connector apparatus comprises a top wall; a bottom wall having one or two openings; two side walls; an internal cavity with a rectangular cross section enclosed by the top wall, the bottom wall and the two side walls; a gasket disposed within the internal cavity; and a first connecting piece made of a conductive material and positioned at the one or more openings of the bottom wall and at least partially covering the one or more openings of the bottom wall, wherein the top wall, bottom wall, two side walls, internal cavity and gasket are configured to comply with a USB interface standard. The USB connector apparatus ensures that a bottom wall elastic sheet of the USB socket effectively contacts with the bottom wall of the USB connector, thereby providing higher grounding performance. Further, it improves on the conventional USB connector without much additional cost.

  • Publication number: 20110038265
    Abstract: A traffic control method, a traffic controlling device, and a terminal are provided, which relate to the field of communications technology. The traffic control method includes the following. A working temperature of equipment is monitored. It is determined whether the working temperature reaches a control temperature. If the working temperature reaches the control temperature, a rate of data interaction between the adjacent function layers is controlled. The adjacent function layers are two random adjacent function layers in a Transmission Control Protocol/Internet Protocol (TCP/IP) 7-layer model. Therefore, a user can use equipment normally when power consumption of wireless terminal equipment is reduced.
