  • Patent number: 6911970
    Abstract: A keypad and key device featuring a plurality of contacts on the rear face of a keypad key that each mate with an individual contact pad from a plurality of contact pads placed below the upwardly biased and tiltable keys. Pushing a key on a right side or left side mates different pairs of contacts and contact pads generating different characters for input to a cellular phone or small computer. Pushing the key in the center will generate a third character by mating both contacts with both contact pads. The keys may also have more than two contacts mating with more than two contact pads and tilt to a variety of positions to mate the respective contacts with contact pads. Consequently, one depression of a key enables any one of a plurality of characters assigned thereto to be inputted which is effective in accelerating a data inputting process.

  • Patent number: 6765555
    Abstract: A passive optical mouse is provided. The mouse does not require an interrogating light source. Instead, the mouse includes a sensor array and lens assembly that captures ambient images from arbitrary sources. A comparison is made between successive images to determine movement of the mouse. The movement of the mouse causes a movement vector to be output, which is used to control movement of a cursor of a computer. In addition, the mouse is configured to provide dual mode operation wherein the mouse can also operate as a video camera.

  • Patent number: 6724354
    Abstract: A display illumination and viewing system has an illumination optical path and a viewing optical path coinciding along a portion of their lengths. A display is located at one end of the coinciding path portion. A first lens system is located on the coinciding path portion and a second lens system is located on the viewing optical path. An illumination assembly is located on the illumination optical path and off the coinciding path portion. The illumination assembly is spaced from the first lens system by a distance corresponding to a focal length of the first lens system. A reflective and transmissive element is located at an opposite end of the coinciding path portion to reflect light from the illumination assembly onto the coinciding path portion toward the display and to transmit light from the display along the viewing optical path.

  • Patent number: 6714173
    Abstract: A screen display apparatus is capable of visually presenting to a viewer E a secondary image 30 (virtual image and/or a real image) as an “inclined” a primary image (subject) 10, and is vertically inclined with respect to said viewer at a position, which is different from a position of said primary image 10. This is realized through an action of a lens 20. With the “inclination, the viewer E views the secondary image 30 with a three-dimensional feeling. The “inclination” is effective when the upper part of the secondary image 30 is located farther from the viewer E than the lower part thereof, and when its angle &thgr; is within a range of 3° to 40°. Further, a screen display apparatus, a plurality of secondary images 30 (in the figures, virtual images 31 and 32) on a primary image 10 as a subject are formed by a microlens array 20 including convex microlenses 221 and concave microlenses 223.
