Title: Fixed bit rate, intraframe compression and decompression of video
Inventor: KOTTKE DANE P
IPC: H04N7/30
Filed: 2004-04-01
Abstract: High quality intraframe-only compression of video can be achieved using rate distortion optimization and without resizing or bit depth modification. The compression process involves transforming portions of the image to generate frequency domain coefficients for each portion. A bit rate for each transformed portion using a plurality of scale factors is determined. Distortion for each portion is estimated according to the plurality of scale factors. A scale factor is selected for each portion to minimize the total distortion in the image to achieve a desired bit rate. A quantization matrix is selected according to the desired bit rate. The frequency domain coefficients for each portion are quantized using the selected plurality of quantizers as scaled by the selected scab factor for the portion. The quantized frequency domain coefficients are encoded using a variable length encoding to provide compressed data for each of the defined portions. The compressed data is output for each of the defined portions to provide a compressed bitstream at the desired bit rate. The bit stream format includes, for each image, a picture header followed by image scan data. The image scan data includes data corresponding to a plurality of macroblock rasterscans. The data for each macrobbck rasterscan includes data for a plurality of macroblocks for a band of lines in the image followed by padding. The padding ensures that data for each macroblock rasterscan terminates on a data boundary. The picture header references an image scan index that indicates a number of macroblock rasterscans in the image scan data and a number of lines per macroblock rasterscan, followed by entries of the index. Each entry in the index includes an offset of the macroblock rasterscan in image scan.

Title: Downhole abrading tools having a hydrostatic chamber and uses therfor
Inventor: LYNDE GERALD
IPC: E21B10/00
Filed: 2007-06-22
Abstract: A downhole abrading tool (10) has a body (20) with a first end (12) for connection to a drill string, a cutting end (14), an exterior surf ace (21), a drilling fluid passageway (26), a valve (80), and a chamber (18). Upon exposure of the chamber to a wellbore fluid pressure due to excessive wear on the cutting end, the valve opens. The opening of the valve permits drilling fluid to flow from the drilling fluid passageway, through the exterior surface and into the wellbore. The flow of drilling fluid through the exterior surface causes a pressure drop that is detected at the surface by an operator of the downhole abrading tool. The valve movement may also cause the release of taggants, or indicators, into the drilling fluid that may also be detected by the operator, either visually or with the aid of detection equipment.

Filed: 2007-06-28
Abstract: The invention relates to the field of document authentication and more specifically to an apparatus and method for validating an enhanced feature contained in a document under analysis. More specifically, a cross plane comparison is used within a document comparison system to validate the authenticity of a security document. Two images are extracted from two colour planes (e.g. visible light and infrared) of a specified page of a security document and the presence/absence of a pattern or text in each plane is determined. In operation, the security document is exposed to two light sources and grey scale images are extracted. Binary images are then obtained from the grey scale images by filtering each grey scale image and then thresholding each grey scale image. The difference between the two binary images is then calculated to determine if a pattern or text is present in both planes or only in one plane. A confidence score is determined from the difference and is presented to an operator of the document comparison system.

Abstract: A shaped metal casting made in an aggregate mold comprises fine solidification microstructure that is finer than the solidification microstructure of an analogous metal casting made from conventional molding processes. The solidification microstructure may be up to five times finer than the solidification microstructure of a conventionally prepared casting.
