Patent GB-2358055-A (GB)
Title: Improved insulated pipework system
Inventor: CODLING RUSSELL
IPC: F16L7/02
Filed: 2001-01-05
Abstract: An insulated pipework system comprises an outer sleeve 12, an inner pipe 10 and one or more evacuated volumes 16 in the space therebetween, defined by annular plugs 1 of a setting polymeric composition such as epoxy resin or a syntactic foam, typically at regular intervals along the length of the pipeline. The epoxy resins (for example) are ideally of sufficient rigidity to allow effective transfer of longitudinal forces between the inner 10 and outer 12 pipes. Thus, the evacuated volumes 16 will themselves be annular. Other plugs of different orientation (for example longitudinal) could be included to subdivide the evacuated volumes further. The plugs 1 allow the space between the pipes 10, 12 to be partitioned so that air can be evacuated from the sections so formed to provide the vacuum that acts as the insulating layer. Also, the plugs 1 replace the need for bulkheads in that the partitioning of the inter-pipe space provides the desired water-stopping means. One or more coatings 2, 3 on the inside of the outer sleeve 12 and/or the outside of the pipe 10 can be provided, of a material that hinders the diffusion of hydrogen or other gases into the vacuum from either the surrounding water or the transported oil. The coating is typically an appropriate alloy, for example aluminium alloy. A plastics liner may also be suitable. Preferably, the vacuum enclosing surfaces are or are provided with a reflective material, which minimises radiative heat transfer. Other coatings may include anti-corrosion coatings. The inter-pipe space may also contain chemicals capable of absorbing gases (so-called "getters") that would otherwise tend to accumulate within the vacuum.

Title: Scalable shape coding of video
Inventor: KING TONY RICHARD
IPC: G06T9/20
Filed: 2001-12-04
Abstract: In a method of processing video into an encoded bitstream in which the encoded bitstream is intended to be sent over a WAN to a device, the processing of the video results in the bitstream (a) representing the video in a vector graphic format with quality labels which are device independent, and also (b) being decodable at the device to display, at a quality determined by the resource constraints of the device, a vector graphics based representation of the video. The quality labels are derived from perceptual significances assigned to contours defining a particular image feature and the labels indicate the position of a given contour in a hierarchy of layers allowing scalable contour coding of an image. This allows a display device to generate a contour representation of the video at a quality level commensurate with the display capabilities of the device by selection of the appropriate hierarchy layers.

Title: A method for locating and reading a barcode
Inventor: MA YUE
IPC: G06K7/14
Filed: 1999-12-16
Abstract: Two-dimensional barcodes surrounded by a quiet zone of white space which may or may not include a border, each barcode having encoded digital information in a bitmap representing preferably randomized encoded data bits, are printed onto a medium. To extract the encoded digital information from the printed medium, if is scanned, then the bitmap is located within the printed medium by moving a window, in stepwise fashion in a predetermined pattern across the printed medium. At each step the portion of the printed medium which is encompassed by the window is tested to determine whether it conforms to one or more characteristics of the bitmap. The skew of the bitmap, if any, is determined, by using a finite-state recognizer in combination with a Hough Transform calculation. The candidate region is divided into a plurality of horizontal regions, preliminary skew angles are calculated for each region, and the actual skew angle is selected using a voting scheme. Once the skew angle is calculated, the bitmap is deskewed if necessary, cropped, and the randomized digital information is read from the bitmap. Finally, the digital information is derandomized and any error correction codes are removed, in the process correcting and/or recording any errors discovered, thereby reproducing the original encoded digital information.

Title: A current mirror bias sensing circuit for a low-noise low-voltage RF amplifier
Inventor: PERRY COLIN LESLIE
IPC: H03F1/22
Filed: 2003-10-01
Abstract: An integrated RF amplifier comprises a pair of amplifying transistors 134A and 134B in a current mirror configuration. The collector current of transistor 134B is compared with a reference current in bias control circuit 144, which regulates the transistor bias currents through resistor 146. The RF signal output by 134B is coupled into the emitter of output common-base transistor 180 through capacitor 166 and appears at the amplifier output. The capacitor cancels the RF differential current of the pair, thereby reducing the associated noise. The transistor 134B may be smaller than 134A. In a variant, two transistor pairs in a mirror arrangement may be configured as a common-emitter and common-base amplifier respectively, for supplying differential current outputs to a mixer (figure 1).
