  • Publication number: 20070211489
    Abstract: A light-pipe (50) includes a first portion (52) for collecting light from a light source (93), and a second portion (54) for transferring the light from the first portion and outputting the light. The second portion is disposed opposite to the first portion. The first portion includes a plurality of protrusions (521) disposed thereon. The light-pipe defines a keyhole (56) extending through the first portion and the second portion.

  • Publication number: 20070076017
    Abstract: An electronic device (100) includes a system module (110), a display module (131), and a control module (120). The display module is for displaying images of the electronic device. The system module includes an image module (111) for saving the image corresponding to a desired orientation of the image. The control module includes a detecting sub-module (123), a setting sub-module (121), and a display control sub-module (122). The detecting sub-module is for detecting a user request for image orientation adjustment on the electronic device. The setting sub-module is for generating a value, corresponding to the orientation requested by the user according to a detecting result of the detecting sub-module. The display control sub-module is for reading the image, corresponding to the value, from the appropriate image sub-module and providing the image to the display module. An image displaying method employed by the electronic device is also disclosed.

  • Publication number: 20050248657
    Abstract: A camera module of image processing and a method for integrating the camera module with a host are described. The camera module has a display control interface, an image sensor, and a camera control circuit. The display control interface is used to control at least one display module. The image sensor is used to capture image and provide image data signals. The camera control circuit is used to control the camera module. The camera module bypasses the display data signals of a host to display control modules according to a bypass signal. The camera module also performs image processing according to the bypass signal and a command set.

  • Patent number: 6851168
    Abstract: A clamp for quickly, effectively and safely removing a cathode collar from an HDP deposition chamber for routine maintenance, cleaning or replacement of the collar. The clamp includes a pair of clamp plates which are capable of pivoting movement on respective ends of a connecting rod. A clamp shoe for gripping a corresponding edge of the annular collar is provided on the bottom end of each clamp plate, and a turnbuckle is fitted with a pair of threaded shafts which engage the upper end portions of the respective clamp plates. By rotating the turnbuckle, the threaded shafts are advanced away from each other against the clamp plates, which pivot on the connecting rod and cause the clamp shoes to tightly engage respective edges of the collar. The clamp is grasped to lift the collar from the chamber and replace the collar in the chamber after cleaning or maintenance.

  • Publication number: 20040179933
    Abstract: A new and improved lift mechanism which is suitably adapted for raising and lowering a pedestal/heater assembly inside a processing chamber for semiconductor wafer substrates. The pedestal/heater assembly lift mechanism includes a drive motor which is directly coupled through a shaft coupling to a threaded lead screw for rotating the lead screw in the clockwise or counterclockwise direction. The lead screw threadibly engages the pedestal/heater assembly for selectively raising and lowering the pedestal/heater assembly inside the processing chamber.

  • Patent number: 5918252
    Abstract: A method and apparatus for generating a modulo address for accessing a circular buffer. The method and apparatus accept as inputs a length L of the circular buffer, a current address A of the circular buffer, and an offset M between the current address and the next address to be generated. The offset M may be positive or negative. During operation of the present invention, the current address A first is broken down into a base address B and an offset from the base address a. Then, in accordance with the length L and the offset M, the invention determines an absolute offset and a wrapped offset. One of these offsets is added to the base address B to generate a next address for the circular buffer. The determination of which offset to add to the base address B is made by performing one of two comparisons.
