US Patent:

6356315, Mar 12, 2002

Filed:

Oct 1, 1998

Appl. No.:

09/165036

Inventors:

Chih-Kang Chen - San Jose CA
Anil Sawe - Saratoga CA
David Tran - San Jose CA

Assignee:

Oak Technology, Inc. - Sunnyvale CA

International Classification:

H04N 716

US Classification:

348581, 348704, 3484401, 348561, 348441, 382298

Abstract:

Magnification/reduction is achieved by a single FIR filter under the control of a Digital Differential Analyzer (DDA) as would be used to simulate a perfectly straight line on a two-dimensional raster. The single FIR filter combines the processes of interpolation, filter, and decimation. The DDA is programmed with the desired magnification/reduction ratio and provides signals that control shifting of input samples into the FIR filter and selection of FIR coefficients for the FIR filter.

International Classification:

G06K 940

US Classification:

382260, 382261, 382298, 708313

Abstract:

A method and apparatus for block-oriented pixel filtering reduces the number of hardware multipliers required for an image processing operation by increasing the speed of the pixel filter and rearranging the math operations. A sorter is employed in the line buffers so that defined groups of input pixel components are provided to the multipliers of the pixel filter. An accumulator is employed to receive products from the multipliers and assemble output pixels. The savings in gate count from reducing the number of multipliers is greater than additional costs, if any, of the sorter and other logic. The method and apparatus of the invention also simplify the addressing logic for the provision of scaling coefficients during an image processing operation.

US Classification:

424613

Abstract:

A medicinal drug is administered to a person for treating a medical condition of the person or/and for preventing the person from contracting the medical condition. The medical condition can be a bacterial infection, a eukaryotic infection, a prion-caused infection, a non-pathogenic inflammation, and, insofar as not covered by any of these four types of the medical condition, a fungal infection, a spore-caused infection, and a parasitic infection. A medicinal drug is similarly administered non-topically to a person for treating a virus-caused medical condition of the person or/and for preventing the person from contracting the virus-caused medical condition. The medicinal drug is typically formed at least partially with salt of peroxymonosulfuric acid, preferably potassium hydrogen peroxymonosulfate.

US Classification:

206438, 562 1, 514578, 424605, 424400, 29428

Abstract:

Products based on salt of peroxymonosulfuric acid are suitable for treating or/and preventing diseases and other debilitating medical conditions caused by bacterial, eukaryotic, prion, and viral pathogens and by non-pathogenic inflammation. The products may alternatively be based on inorganic halide and an oxidizing agent reactable in water with the inorganic halide to generate hypohalite ions. In addition, the products can be employed in other applications such as commercial and industrial applications.
