Abstract: A method for processing a received signal at a mobile receiver of a wireless communications system is disclosed. The method comprises demodulating the received signal to obtain an analog base band signal and converting the analog base band signal into a digital base band signal. The signal strength of the digital base band signal is estimated and, using the estimation, the digital base band signal is scaled by a scaling factor. The digital base band signal is equalized into an equalized digital signal which is then rescaled by a resealing factor.

Abstract: A method and apparatus for large scale noise decoupling in an integrated circuit is disclosed herein. A power decoupling mesh and a power distribution structure are included in the integrated circuit. The power decoupling mesh is configured in accordance with the power distribution structure. The power decoupling mesh comprises a plurality of decoupling capacitors, such as trench capacitors or MOSFETs.

Abstract: A digital image upscaling system enhances the visual quality of enlarged images by detecting diagonal edges and applying an appropriate scaling algorithm, such as a rotated bilinear scaling process, to output pixels associated with those edges. The rotated bilinear scaling process involves detecting diagonal edges and specifying a new frame of reference rotated 45° from the original frame of reference, and then selecting a rotated pixel set based on the new frame of reference. Bilinear interpolation in the new frame of reference using the rotated pixel set provides improved pixel data for the output pixel. Output pixels found not to be associated with diagonal edges are processed using standard bilinear interpolation.

Abstract: A method and system enhances the color of an image by manipulating the chrominance and/or luminance signals of the image. Specifically, a color enhancement system sharpens color changes for better picture quality on digital display systems. In one embodiment of the present invention, color changes are detected by a color change detection unit. If the color changes are significant, a color change sharpening unit sharpens the color change to enhance the image.

Abstract: A method and system of noise filtering is provided. The pixels of a first filter mask are separated into groups based on luminance . . . The sizes of each group is determined and a largest group is selected. The distance of each group of pixels from the largest group is also calculated. Pixels in groups that are small compared to the largest group and far from the largest group are tagged as noisy. After tagging the noisy pixels, additional filtering can be applied to the pixels of first filter mask without degradation from the tagged pixels.

Abstract: A new and improved bonding pad having separate areas for probe needle contact and wire bonding in semiconductor packaging technology. The bonding pad typically has a generally elongated, rectangular configuration with a wire bonding area at one end and a probe needle contact area at the other end of the pad. At least one notch mark may be provided on or adjacent to the bonding pad between the wire bonding area and the probe needle contact area for demarcating these areas during chip production.

Abstract: A method and circuit generates a complete picture from a series of digitized interlaced video fields. Each pixel in the complete picture is either duplicated from a digitized interlaced video field or interpolated from three adjoining digitized interlaced video fields. Interpolated pixels are computed from a combination of same-field and adjoining-field pixels. A percentage difference of the luminance values of the same-field and adjoining-field pixels included in the interpolation is used to maximize motion capture in the de-interlaced picture. Additional embodiments incorporate filtering of the percentage difference based on a threshold value to minimize soft noise in the de-interlaced picture.

Abstract: In a cache memory system, continuation registers are provided to abbreviated address data identifying the line position in the cache memory from which data is fetched. When data is fetched from a line in said cache memory, the bin number and line position identification of the line in the cache memory are saved in a continuation register. Then, subsequently, when data is fetched from the same line, it is fetched by a continuation request wherein the data saved in the continuation register is used to access the cache memory. The continuation registers provide the abbreviated address data for comparison in both PSC (program store compare) and OSC (operand store compare).

Abstract: Micromachined microvalves are held both open and closed electrostatically to maintain uniform gas microflow and improve closure characteristics. A microflow controller containing such a valve is combined with a predetermined restricted flow path. Multiple valve/restrictive flow path combinations are integrated on a binary flow path basis. Single and/or multiple valve actuation provides precise but variable flow control. Temperature and pressure sensors can be integrally included. Various valve and controller configurations, and methods of controlling them and forming them, are disclosed.
