Title: Image data compression by sub-band coding and subsequent run-length coding
Inventor: WILKINSON JAMES HEDLEY
IPC: H04N7/26
Filed: 1992-01-16
Abstract: Input image data is coded into sets of two-dimensional sub band image data are run-length coded by a run-length coder 60. The run-length coder 60 assigns codes to runs of zero values terminated by a non-zero value, runs of constant non-zero values and particular individual data values. The output from the run-length cod or 60 is fed to a Huffman coder 62 where it is Huffman coded. The Huffman coding table 64 applied by the Huffman coder 62 and the type of run-length coding applied by the run-length coder 60 varies. Implementations need only use a sub-set of possible runs of zero values terminated by a non-zero value and runs of constant non-zero values without an undue loss in compression efficiency. <IMAGE>

Patent GB-2262175-A (GB)
Title: Reconfigurable signal processor
Inventor: GORIN ALLEN LOUIS
IPC: G06F15/177
Filed: 1993-01-28
Abstract: Each 4-port processing elements (PEs) 50 arrayed in a module has four physical ports N, S, W, E which connect to the similar ports of its lattice neighbors. Each PE has an internal capability 54 to be configured to route signals to or from any of its neigbours. Thus, for tree topologies, any of the four neighbors of a given PE may be selected as the parent of the given PE; and any or all of the remaining three neighboring PEs may be selected as the child(ren) PEs. The PE ports N, S, W, E are configured under the control of a remote Host 60, which establishes a desired PE topology. This is achieved by effecting or blocking signal routes between the element's processing capability and its ports. Therefore each is conditioned to direct signals to and from only selected ones of each neighbouring PE. <IMAGE>

Title: Method for regaining mud circulation in operating well and device for its embodiment
Inventor: EFIMKIN ALEXEI ALEXEEVICH
IPC: E21B33/068
Filed: 1992-12-01
Abstract: In a well for example in a column of riser pipes (1), a hydromechanical cleaner (3) is descended on a pipe column (2). The plug (4) is subjected to the jet effect of the direct downward flow of washing liquid pumped down through the pipe column (2), so as to wash it out. As the plug is washed out, the cleaner (3) is moved down by advancing the pipe column (2). The rising flow of the washing liquid turns cleaning heads (5, 6) in opposite directions. Cutting blade elements of the heads (5, 6) provide for mechanical removal of sediment from the walls of the column of riser pipes (1). The mechanical removal of the sediment from the walls is effected both during lowering and raising of the cleaner (3). The product of plug (4) disintegration and the sediments are removed by the ascending flow through a lateral tapping sleeve (41) of a face washing head (18). A device for implementation of the method further comprises a mechanism for moving the pipe column (2) as well as pumping equipment. <IMAGE>

Title: Distributed clock signal and clock signal interrupt
Inventor: WONG KENG L
IPC: G06F1/32
Filed: 1994-04-25
Abstract: A clock distribution system and clock interrupt system provides clock signals with less than 100 picoseconds of skew to various components of an integrated circuit 200 (ignoring effects associated with the matched stages) by using several stages of drivers 301, 310 - 314, 30a - 30l to evenly supply the distributed clock signals. Each stage has RC matched input lines e.g. 340 - 344. The matched stages and clock drivers are located within the power supply ring of the integrated circuit located on the periphery of the microprocessor topology. This is done in order to better predict the topology surrounding these lines to match the capacitance of these lines. Further, this metal level offers a larger width dimension line (since as a top layer it may be thicker) having less resistance per unit area and also generally avoids spatial competition with other IC components and circuitry. The drivers can be selectively powered downs in groups by a power management unit. <IMAGE>
