Abstract: A device includes an upper unit having a display screen thereon and a first slidable unit having a first keypad thereon. The first slidable unit is slidably connected to the upper unit on a side opposite the display screen. The first slidable unit is movable between a closed position in which the upper unit generally overlies the first keypad and an open position in which the first keypad is positioned generally adjacent the display screen. A second slidable unit has a second keypad thereon. The second slidable unit is slidably connected to the upper unit and the first slidable unit. The second slidable unit is movable between a closed position in which the upper unit generally overlies the second keypad and an open position in which the second keypad is positioned generally adjacent the display screen.

Abstract: An electronic device includes an upper display unit and a lower keypad unit. The display unit has a display screen thereon. The display unit has first and second opposed side edges. The keypad unit has a first region and a second region and includes a first keypad on the first region and a second keypad on the second region. The keypad unit is slidably connected to the display unit on a side opposite the display screen. The keypad unit is movable relative to the display unit along a slide axis between: a closed position in which the display unit generally overlies the first keypad and the second keypad; a first open position in which the first keypad is exposed and positioned adjacent the first side edge of the display unit; and a second open position in which the second keypad is exposed and positioned adjacent the second side edge of the display unit.

Abstract: A power adapter includes a primary side for receiving power from a mains power supply; a secondary side for providing operating and/or charging power, derived from the primary side, to an electronic device connected to the secondary side; presence logic for determining whether the electronic device is connected to the secondary side; and switching logic for turning off the primary side automatically when the presence logic determines the electronic device is not connected. The power adapter thus shuts itself down if no electronic device is attached, and automatically starts itself up when a device is connected to the power adapter and is thus needed. The power adapter may also include voltage detection logic that detects when the device is fully charged. The power adapter also shuts itself down when an attached electronic device becomes fully charged, and automatically starts itself up when the charged state of the electronic device falls below a predetermined level.

Abstract: A system includes a touch panel, a touch panel controller and a voltage source. The touch sensitive touch panel is formed with one or more piezoelectric elements disposed in an interior of the touch panel. The touch panel controller identifies an occurrence of a touch upon the touch panel and generates one or more control signals based on the occurrence of the touch. The voltage source receives the one or more generated control signals, and applies voltages to at least one of the one or more piezoelectric elements based on the one or more control signals.

Abstract: An electronic device includes a display and a touch input assembly disposed over the display. The touch input assembly includes a first touch sensor configured to function as a general purpose user input for data entry and for controlling functions of the electronic device in coordination with content displayed on the display. The touch input assembly also includes a second touch sensor configured to receive user touch input to wake up the first touch sensor from a stand-by state of the first touch sensor.

Abstract: A multilayer printed circuit board may include a first layer, a second layer, and a third layer, the second layer being between the first layer and the second layer. The second layer may include a spark gap.
