  • Patent number: 9939926
    Abstract: A pointing device is disclosed. The pointing device includes an operation cap having an operation surface fitted into a stud. The stud is fixed to a keyboard plate with a screw from below together with a sensor plate. A waterproof material is provided between the stud and the keyboard plate. Multiple pressure sensors are arranged below the keyboard plate. The pressure sensors are applied with a predetermined pressure beforehand. When the operation surface is depressed, the stud and the sensor plate slide and move downward while being tilted to reduce the detection pressures of the pressure sensors. Since the pressure sensors exist below the keyboard plate, the operation cap can be downsized, and the pressure sensors can be protected from impact to the operation cap.

  • Patent number: 9847192
    Abstract: A keyboard device is disclosed. The keyboard device includes a base, a key top, a film actuator, a position sensor, and a controller. The key top is movably arranged on the upper surface side of the base. Disposed between the base and the key top, the film actuator bends according to an applied voltage. Also disposed between the base and the key top, the position sensor detects a position of the key top. The controller applies a voltage to the film actuator in order to generate a repulsive force corresponding to the position of the key top detected by the position sensor.

  • Patent number: 9430056
    Abstract: A pointing device for a portable computer is disclosed. The pointing device includes an operation cover for covering a first and second pressure sensors. The pointing device also includes one front operation surface and two rear pressure faces. Detection axes are arranged in a vertical direction, and the pressure faces are so inclined that normal lines will approach each other above the operation surface. The operation surface is applied with depression pressure P1 including a horizontal component Ph and a vertical component Pv. Even when any position on the operation surface is pressed down, pressure P2a detected by the first pressure sensor becomes greater than pressure P3a detected by the second pressure sensor.

    Abstract: Devices and methods are provided for electronic pointing device acceleration. In general, the devices and methods can facilitate adjustment of a speed of a cursor's movement on a display screen. In one embodiment, an electronic device can include a pointing device configured to control movement of a cursor on the electronic device's display screen. A user's input to the pointing device can indicate a desired distance and directional movement of the cursor on the screen. The electronic device can also include an accelerator element configured to control a speed of the cursor's movement on the screen. A user's input to the accelerator element can indicate a desired increase in the cursor's speed and cause the cursor to move more quickly on the screen. The electronic device can include the pointing device and the accelerator element at locations compatible with typical typing positions of a user's hands.

  • Patent number: 8499143
    Abstract: A computer system having an operating environment configured for enabling boot up in a relatively short time is disclosed. A hard disk is utilized to store a boot file. A run process list registers a process to be run during boot up. When the computer system is being booted up, if the run process list registers a process to load the boot file, a process control unit does not control a process management unit, so that the process is run as usual. If the process is not registered, the process management unit suspends the process. When the suspended process is called by another process later, the process control unit makes the process resumed on demand.
