  • Patent number: 9881750
    Abstract: A multicolor illumination keyboard includes a light-emitting element, a color filter and plural keys. The plural keys are located above the light-emitting element. The color filter is arranged between the plural keys and the light-emitting element. After a source light emitted by the light-emitting element passes through the color filter, plural color lights are generated. The plural color lights are outputted from the plural keys. Consequently, the plural keys are illuminated in a multicolor manner.

  • Patent number: 9847190
    Abstract: A key structure includes a supporting plate, a keycap, a scissors-type connecting element, a movable element and a coupling structure. The keycap is disposed over the supporting plate. The coupling structure is connected with the scissors-type connecting element and the movable element. For operating the key structure, the cooperation of the movable element and the coupling structure allows the keycap to be at a higher first height. Consequently, the tactile feel of depressing the key structure is enhanced. Moreover, the cooperation of the movable element and the coupling structure can lower the height of the keycap. Consequently, the key structure has a slim appearance.

  • Patent number: 9845048
    Abstract: A car door opening pre-detection system for a car includes a first detecting module, a second detecting module and a control module. The first detecting module is installed within the car. The first detecting module issues a motion detecting signal according to a result of detecting a motion of a palm. The second detecting module is installed outside the car. When the car is stopped, the second detecting module is enabled to selectively provide a first detection range or a second detection range. The control unit judges whether a car door of the car is about to be opened according to the motion detecting signal. When the car is stopped and the control module judges that the car door is about to be opened, the second detecting module provides the second detection range to detect whether there is a moving object behind the car.

  • Patent number: 9773626
    Abstract: A keyboard includes a base plate, plural keycaps, plural scissors-type connecting elements and a sliding plate. Each scissors-type connecting element has a bulge. The gliding plate has plural position-limiting structures. The keyboard is installed on a notebook computer and connected with a top cover of the notebook computer. For operating the keyboard, the bulge is received in a first step part of the position-limiting structure. Consequently, the keycap is at a higher height. Since the keycap is at a higher height, the movable distance of the keycap is large enough to provide better tactile feel. For storing the keyboard, the bulge of the scissors-type connecting element is moved to the second step part of the position-limiting structure. Consequently, the height of the keycap is reduced, and the keyboard has a slim appearance.
