摘要： The PTT assembly (100) self locates and then locks a back support plate (106) and switches (146, 148) directly to an inner surface (134) of a housing wall (132). On the outer surface (136) of the housing wall (132), keypad plungers (116) self locate through holes (140) in the housing wall. The perimeter of the keypad itself is retained by a bezel (110) that snaps into the housing (132). A hook (130) extends from the bezel (110) to lock and fix the travel distance of the plungers (116) to the switches (146, 148). With the back support plate (106) firmly in place, the keypad actuation force remains consistent since the travel distance of the plungers (116) to the switches (146, 148) is fixed by the hook (130) length. Additionally, the back support plate (106) supports the switches without bowing under the applied plunger force further ensuring a consistent actuation force.

摘要： A method of displaying images with an electronic display device having a plurality of sequentially updatable picture elements includes displaying an image with the picture elements by sequentially updating each of the plurality of picture elements, filtering light emanating from a first picture element with a first polarizing filter configured in a first polarization orientation and filtering light emanating from a second picture element with a second polarizing filter configured in a second polarization orientation that is different than the first polarization orientation. The method further includes detecting an update of a third picture element and switching the configuration of the second polarizing filter to the first polarization orientation in response to detecting the update of the third picture element.

摘要： A method and apparatus for display of graphical data is described. The invention provides an architecture for graphics processing. The architecture includes pipelined processing and support for multi-regional graphics. In one embodiment, a graphics driver according to the invention can receive multiple independent streams of graphical data that can be in different graphical formats. The independent streams are synchronized and converted to a common format prior to being processed. In one embodiment, multi-regional graphics are supported with off-screen and on-screen memory regions for processing. The regions of the multi-regional graphic are rendered in an off-screen memory. The data in the off-screen memory are converted to a common format and copied to on-screen memory. The data in the on-screen memory is used to generate an output image. Alpha blending can also be programmed to provide multi-regional graphics or other graphical features. In one embodiment, graphics processing is programmable and can be paced using a set of registers.

摘要： The present invention is a method and apparatus for correcting aspect ratio of a display by scaling a source array of pixel data in a memory by a scale factor to a destination array of pixel data. The apparatus comprises a coefficient unit, a register unit, and an arithmetic unit. The coefficient unit is coupled to a buffer to load N coefficients. The register unit is coupled to the source array to load N pixel data synchronously with the coefficient unit. The N pixel data are started at a location in the source array according to the scale factor. The arithmetic unit is coupled to the coefficient unit and the register unit to perform a filtering operation on the loaded N pixel data using the corresponding N coefficients. The arithmetic unit generates a filtered output corresponding to a scaled pixel in the destination array.

摘要： The invention provides a method and apparatus for conversion of video data from a source format to a second destination. Conversion can be performed in real time and intermediate data is stored in a buffer. Converted video data is written into the buffer at a first rate and read out of the buffer at a second rate. In order to avoid overflow and underflow conditions, a threshold value is determined based, at least in part, on the video format being converted. The threshold value indicates a point in frame conversion at which converted data is read out of the buffer.
