  • Patent number: 11891965
    Abstract: A turbofan engine nacelle includes a thrust reverser system provided with at least one movable cowl retracting towards a rear reverse-jet position, tilting pivoting flaps which at least partially close an annular flow duct, and opening lateral openings of this annular flow duct equipped with reverser grids. Each movable cowl includes a control sector that slides in a transverse plane, a deflection device linking a fixed part of the nacelle to this control sector in order to make it slide towards a reversal position when the movable cowl retracts, and flap connecting rods linking this control sector to the pivoting flaps, which tilt these flaps, closing the annular flow duct, when the control sector slides towards its reversal position.

  • Patent number: 8707328
    Abstract: An application program switching method for an electronic device having a first body and a second body is provided. A relative position of the first body and the second body is changed from a first state to a second state to activate a second application program while an external message is received during a first application program being executed, and an image displayed by the electronic device is switched from an executing frame of the first application program to an executing frame of the second application program for replying the external message via a keyboard of the second body. Next, the relative position of the first body and the second body is changed from the second state to the first state, and the image displayed by the electronic device is switched from the executing frame of the second application program to the executing frame of the first application program.

  • Patent number: 7425948
    Abstract: A stylus for a portable apparatus is disclosed. The stylus is usable as a prop to support the portable apparatus to stand on a platform and comprises a main portion and a rotating portion. The main portion comprises a tip end and a pivot end, and at least one protruding rib is disposed on the pivot end. A positioning plate is disposed on one end of the rotating portion, and connects with the protruding rib. A bolt passes through the protruding rib and the positioning plate, so that the rotating portion could pivotably connect with the main portion. Furthermore, at least one positioning structure is formed on one end of the positioning plate. The cross-sectional shape of the positioning structure is an arc shape. The stylus further comprises an elastic component and a positioning ball. The elastic component presses the positioning ball in the positioning structure, so that the portable apparatus could stand on a table surface. In addition, at least one groove is disposed on the sidewalls of the stylus.
