  • Patent number: 6731434
    Abstract: A compact, ultra-light and high-performance projection optics lens assembly using Diffractive Optics Technology, plastic and glass optics, and Aspheric optics has been designed with only four elements. The lens may be included as is, or scaled to be included in all instruments using conventional Double-Gauss lens forms. The preferred lens is only 20 mm in diameter and 15 mm long has a weight of only 8 g. Thus, two lenses for head mounted stereo displays is only 16 g. Such a stereo display, known as a head-mounted projective display (HMPD), consists of a pair of miniature projection lenses, beam splitters, and miniature displays mounted on the helmet, and retro-reflective sheeting materials placed strategically in the environment.

  • Patent number: 6704148
    Abstract: A retainer is constructed of a retainer top section, a retainer body section and a retainer bottom section. Connecting portions of the sections are screwed by screws provided for the connecting portions with interposition of an O-ring. A mirror having a surface of revolution is mounted on the top portion of the body section. The bottom section is assembled with a mounting base for movably mounting an image pickup device and with a fixture for fixing the image pickup device to the mounting base. There is thus obtained a compact omnidirectional visual angle system, which has a waterproof function and does not interrupt the visual angle and in which the retainer structure of the mirror and the image pickup device, the distance therebetween can be varied, is integrated with an exterior casing for sealing use. The retainer can easy replace the components.

  • Patent number: 6661565
    Abstract: A packaging method of the optical transceiver module for transmitting optical signals is disclosed. The invention includes a base, a case, a transmission unit and a receiving unit. The transmission unit and the receiving unit contain a circuit board, respectively. The base provides two fixing positions for the installation of the two circuit boards. The two circuit boards are installed horizontally and vertically, respectively. This design increases the utilization of the inner space, providing ideal shielding for the elements and circuit boards. A central beam is used to fix the structure and case in a drawable way like a matchbox. This reduces covered area of the circuit board, making the elements easy to be tested and assembled.

  • Patent number: 6650462
    Abstract: An active matrix electrophoretic display is driven. In a reset period Tr a reset voltage is applied to each pixel electrode. Next, in a writing period an applied voltage is applied to each of said pixel electrode during a time period corresponding to a gradation value designated by an image data. Next, a common voltage is applied to each of said pixel electrode, so that electric charge accumulated in each capacitor is taken away and no electric field is applied to each dispersal system, thereby a displayed image is held.

  • Patent number: 6643007
    Abstract: A dynamic reflective spatial attenuator for use in an optical inspection apparatus. The attenuator takes the form of a two-dimensional micro-mechanical reflective array that, in the first operative position of a mirror element, reflects the desired scattered light toward a detector and, in the second operative position of a mirror element, reflects undesired scattered light into a light dump. The mirror array's fast response and flexibility allows for changes during mid-scan to increase the defect's or contaminant's signal relative to the substrate surface's signal.
