  • Publication number: 20160253053
    Abstract: Electronic equipment is controlled with a touching-type signal input device. An inputted navigator-calling request that specifies a user request to navigate among a set of previously-opened application views of different applications is received. A request mode of the inputted navigator-calling request is compared with a predefined request mode associated with navigation among the set of previously-opened application views of the different applications. It is determined whether the request mode of the inputted navigator-calling request matches with the predefined request mode. An open-views navigator is displayed in response to determining there is a match. The open-views navigator has a set of open-views tabs distributed on at least part of a closed structure that each allow selective navigation to a previously-opened application view of one of the different applications.

  • Patent number: 9146170
    Abstract: An overmolded pressure sensor package is provided. The pressure sensor die (Pcell) is capped so that the Pcell has enhanced rigidity to withstand stress effects produced by the molding encapsulant. The Pcell cap includes a hole located away from the Pcell diaphragm, so that external gas pressure can be experienced by the Pcell, while at the same time directing moisture away from the diaphragm. Gel does not need to be used, and instead a soft film can be deposited on the Pcell to protect the Pcell diaphragm from excess moisture, if needed. The Pcell cap can take the form of, for example, a dummy silicon wafer or a functional ASIC.

  • Patent number: 8979098
    Abstract: A foldable platform truck includes a platform, two wheel-connecting bars rotatably attached to the platform, a handle assembly, a handle release and locking mechanism for controlling the handle assembly, a pair of first gear members and a pair of second gear members. The handle release and locking mechanism has an actuator to be operated to allow the handle assembly to pivot between an upright position and a horizontal position. When the handle assembly is in the horizontal position, the wheels are folded up underneath the platform and lie horizontally with respect thereto. And, when the handle assembly is pulled away from the platform to the upright position, the first gear members engage and turn the second gear members, resulting in the wheel-connecting bars rotating to fold out the wheels from underneath the platform toward an eventual perpendicular position with respect to the underside of the platform.
