  • Patent number: 6864476
    Abstract: A method of reading out a light signal from a pixel is disclosed. The method comprises first charging a capacitor to a predetermined voltage during a precharge stage. Next, during a readout stage, discharging the capacitor for a predetermined length of time through a pixel output transistor. The pixel output transistor is modulated by the light signal by applying the light signal to the gate of the pixel output transistor. Finally, the output signal is determined to be the voltage held by the capacitor.

  • Publication number: 20040267508
    Abstract: A computer numerical control (CNC) code-simulating system includes a number of client computers (6), a server (1), and a database (2). The database stores all information used and generated by the system. The client computers provide user interfaces enabling users to timely view information on machining of workpieces. The server is connected to a production management system (5), and is used for: obtaining turret information and machining paths of tools from the database; generating CNC code files according to the turret information and the machining paths of tools; constructing figurations of the tools according to parameters of the tools recorded in the CNC code files; simulating machining of the workpieces according to the figurations, the machining paths and of the tools and the turret information; and exporting relevant production management information to the production management system to generate statements for controlling of machining processes. A related method is also disclosed.

  • Patent number: 6725620
    Abstract: A sealing mold arrangement includes at least an elongated mold strip adapted for mounting to an attachment corner edge of a panel frame such as a door and window frame. The elongated mold strip has an elongated first and second attachment surfaces and an alignment corner edge formed at a common line-edge where the first attachment surface meets the second attachment surface. Each of the first and second attachment surfaces has a longitudinally extended positioning guider sharp edge, a longitudinal attachment groove transversally extended from the positioning guider sharp edge towards an inner portion of the respective first and second attachment surfaces, and an edge gap surface transversally and inclinedly extended from the positioning guider sharp edge to the distal side edge of the respective first and second attachment surface to form an edge gap.

  • Patent number: 6401790
    Abstract: A magnetic dual glasses window structure includes a window blind, provided between two panes of glass, including tilt cords for supporting a plurality of slats and an operating system which includes a shaft attached to the tilt cords and a magnetic actuating device. The magnetic actuating device includes an actuating cord movably and encirclingly attaching to two end portions of the shaft, a pair of resilient elements attached to the actuating cord respectively for applying an urging force against the actuating cord, a magnetic seat connecting between the two resilient elements and positioned adjacent an inner surface of one of the panes of glass, and a magnetic slider positioned adjacent an outer surface of the pane of glass for magnetically driving the magnetic seat to move. Therefore, by sliding the magnetic slider, the actuating cord drives the shaft to rotate for controlling the tilt angle of each of the slats.
