Patent CA-2380194-A1 (CA)
Inventor: RANDOLPH SCOTT W
IPC: G01M3/02
Filed: 2002-04-03
Abstract: A method and device for pressure testing a pipe line is provided wherein a fitting is inserted into the pipeline by inserting male ends of the pipeline into female ends of the fitting to define a flow path through the fitting extending along a longitudinal axis. The fitting has an internal boss extending around a circumference of the flow path and extending radially inward toward the centerline a distance corresponding to the wall thickness of the mating male ends of the pipes so the pipes and boss define a periphery of the flow path through the fitting. A recess is formed in the boss to sequentially receive two slides. An externally accessible port allows a test slide to be inserted into the recess, with the test slide sealing against the walls defining the recess to form a fluid-tight seal for pressure testing the line. The test slide is removed and a finish slide is inserted into the recess. The finish slide has an opening located and configured to coincide with the flow path through the male ends of the pipes, and to block the recess to provide a substantially uniform, cylindrical flow path through the fitting.

Title: Multi-channel surround sound mastering and reproduction techniques that preserve spatial harmonics in three dimensions
Inventor: MOORER JAMES A
IPC: H04S3/02
Filed: 2000-10-06
Abstract: Techniques of making a recording of or transmitting a sound field from eithe r multiple monaural or directional sound signals that reproduce through multip le discrete loud speakers a sound field with spatial harmonics that substantial ly exactly match those of the original sound field. Monaural sound sources are positioned during mastering to use contributions of all speaker channels in order to preserve the spatial harmonics. If a particular arrangement of speakers is different than what is assumed during mastering, the speaker signals are rematrixed at the home, theater or other sound reproduction location so that the spatial harmonics of the sound field reproduced by the different speaker arrangement match those of the original sound field. An alternative includes recording or transmitting directional microphone signal s, or their spatial harmonic components, and then matrixing these signals at th e sound reproduction location in a manner that takes into account the specific  speaker arrangement. The techniques are described for both a two dimensional  sound field and the more general three dimensional case, the latter based up on using spherical harmonics.

Abstract: A diagnostic method and device for use in detecting or quantitating an analyte present in a liquid sample. The method includes reacting an analyte-containing sample with reagents capable of generating a first coil-forming peptide in solution form. This peptide is then contacted with a biosensor whose detection surface has surface-bound molecules of a second, oppositely charged coil-forming peptide, under conditions effective to form a stable .alpha.-helical coiled-coil heterodimer on the detection surface. The formation of the coiled-coil heterodimer produces a measurable change in biosensor signal, when is measured to detect the presence of or quantitate the amount of analyte in a sample.
