Title: List output viterbi decoding with crc outer code for multi-rate signal
Inventor: STEIN JEREMY M
IPC: H03M13/00
Filed: 1998-03-20
Granted: 2007-07-24
Abstract: A method and apparatus for decoding a frame of multi-rate encoded digital data which contains redundant information provided to validate the decoding operation. A frame of data is received which contains information bits and cyclic redundancy check (CRC) bits. In accordance with the invention, the received frame is decoded and a check is conducted to determine whether the CRC bits correspond correctly for the decoded information bits. If the decoded frame passes the CRC test process, the decoded frame is provided to the user. However, if the decoded frame does not pass the CRC test, then at least one additional decoding process is performed on the received frame. In the first exemplary embodiment of the present invention, on a failure of the CRC check, the data is decoded using a trellis decoder (224) and the data that yields the next most likely path through the trellis is selected. In a second illustrative embodiment, if the CRC  test fails, the trellis decoder (224) then identifies all paths having metrics within a predetermined threshold of a metric associated with the optimal path through the trellis. The CRC test is then performed on the decoded frame with respect to the suboptimal paths (starting with the most likely path). If any of these paths pass the CRC check, the information bits are output by the decoder (224). If not, an error is declared.

Abstract: A system for enhancing hydrocarbon production in long and deviated subterranean wells, comprises proppant in the annulus between the screen liner and the borehole, annular isolation elements, and selective flow control in combination. The significant control provided by the system enables the well operator to impose sequential control or commingled production from multiple producing intervals of the borehole. A differential valve is incorporated in the screen liner service string to allow for proppant placement across multiple screen-liner sections, separated by annular isolation elements in a single placement operation, thereby significantly reducing time and complexity of such operations.

Abstract: A transcoder has a decoder fo decoding a received video signal which has been coded according to a first coding scheme employing motion compensation and carries coded data and motion compensation information, and an encoder for encoding the output of the decoder according to a second coding scheme also employing motion compensation. The transcoder generates estimated motion vectors for a current frame of the video signal, using vectors which, in the received signal, accompany at least one other frame of the video signal. These may be used directly by the encoder or used to define a search area for motion estimation.

Title: Novel lactic acid bacterial preparation that reduces triglycerides and cholesterol
Inventor: HATA TADAYO
IPC: A61K35/747
Filed: 2000-07-31
Granted: 2006-11-28
Abstract: Although the inventors previously found that the novel species designated Lactobacillus clearans was highly effective for health purposes, they noted in particular that this species lacked sufficient intestinal purification action. Efforts to produce a species of higher potency and the like to remedy this drawback led to the unavoidable conclusion that the use of a bacterium by itself produced limited results. The concurrent use of another active substance was thus considered in seeking a lactic acid bacteria preparation capable of invigorating healthy individuals, and of renewing a sense of well being and restored health in semi-sick individuals or semi-healthy individuals.      The invention relates to a lactic acid bacteria preparation, comprising viable cells of Lactobacillus clearans, and either or both of viable and killed cells of Enterococcus faecalis capable of reducing one or more of at least triglycerides and cholesterol.

Title: Process and apparatus for sludge and scum extraction
Inventor: BRAUCHLI HERBERT
IPC: B01D21/00
Filed: 2000-09-26
Granted: 2009-06-16
Abstract: A sludge extraction apparatus including a sedimentation tank; a float; a catch tank with an overflow rim, which runs partially or completely around the float; a mixing unit to generate a fluid flow pattern within the sedimentation tank which provides a fluid flow at the surface of the water towards the catch tank; and a conveyor, which conveys the sludge, overflowing into the catch tank, through an outlet line. The flow generated by the mixing unit moves the scum on the surface of the water to the catch tank, where the scum can be collected. By controlling the mixing unit, the fluid flow can be selected to convey only the light weight particles in the sludge, so that the scum and the light--weight sludge partitions can be extracted selectively and from over a large area. The sludge extraction apparatus is conveniently located in the sedimentation tank by a parallelogram linkage.

Inventor: VINCENT RAY
IPC: E21B34/10
Filed: 2001-04-27
Granted: 2005-03-29
Abstract: The invention is a well fluid production valve that is positioned downhole in a closed condition below an upper formation packer. The valve comprises a cylindrical mandrel having central bore flow connection with the upper bore of well fluid production tubing and coaxially aligned within the lower bore of the production tubing string. Flow port apertures through the mandrel wall provide well fluid flow paths between the mandrel O.D. and the bore I.D. of the lower production tubing. These flow ports are covered to close the valve by a sliding sleeve around the mandrel O.D. The sliding sleeve is spring biased to the open position but also secured at the closed valve position by an annular piston actuated sear mechanism. Actuation pressure for opening the valve to admit a flow of well fluids from the production zone is a predetermined differential between the well pressure above the packer, usually a function of the well depth, and the operator controlled pressure within attached production tubing. The formation pressure, which may be more or less than the corresponding head pressure, is isolated from the valve actuator and therefore does not contribute to the valve actuating pressure. A fluid pressure conduit is provided that transmits fluid pressure from a well annulus zone above the upper formation packer down past the packer to the upper face of the annular piston within an annular valve actuation cylinder. Production tubing bore pressure is routed to bear upon the lower face of the annular piston. Sufficient pressure differential on the annular piston displaces the sear piston from the sleeve holding position with the sear piston removed. The standing spring bias on the sleeve slides it along the mandrel O.D. to open the flow ports.
