Patent CA-2206127-A1 (CA)
Inventor: WEININGER ARTHUR M
IPC: C12Q1/68
Filed: 1995-12-07
Abstract: This invention is a novel method for detecting and localizing specific nucleic acid sequences in a sample with a high degree of sensitivity and specificity. The method and novel compositions used in the method involve the use of Probe Nucleic Acids, the production of nucleic acid binding regions and the use of nucleic acid Target Binding Assemblies to detect and localize specific Target Nucleic Acids. The detection and localization of the Target Nucleic Acid is accomplished even in the presence of nucleic acids which have similar sequences. The method provides for a high degree of amplification of the signal produced by each specific binding event. In particular, methods and compositions are presented for the detection of HIV and HPV nucleic acid in samples. These methods and compositions find use in diagnosis of disease, genetic monitoring, forensics, and analysis of nucleic acid mixtures. Some of the novel compositions used in the detection method are useful in preventing or treating pathogenic conditions.

Patent CA-2208112-A1 (CA)
Inventor: YAO CHONG-GUO
IPC: H05H9/00
Filed: 1997-06-18
Abstract: In a clinical linear accelerator system for delivering charged particles for medical applications, a series of monolithic cavity-defining members is connected to form a succession of accelerating cavities, with temperature regulation being achieved by aligning internal cooling passageways through the series of monolithic members. As a result, a continuous coolant flow path is formed through the monolithic members. At each member-to-member interface, there is a leakage-release path for non-intrusively conducting any leakage that occurs at the interface. In the preferred embodiment, there is a braze connection that separates the leakage-release path at an interface from the coolant flow path at that interface. The braze connection provides a seal that further safeguards against coolant entering an area in which performance of the system is affected.

Inventor: BENGE WILLIAM DENNIS
IPC: A47K7/02
Filed: 1996-01-05
Abstract: A personal cleansing implement (34) comprises a substantially rectangular hydrophobic batt (26). The batt (26) is a piece of knitted tubing (10) made from extruded linear low density polyethylene monofilaments knitted into a tube (10) on a knitting machine having a setting ranging from 32 to 64 needles per machine diameter. The monofilaments have substantially circular cross sections in the range of 0.003 inches to 0.015 inches diameter. The piece of knitted tubing (10) also has a longitudinal axis with about 6 to about 9 stitches per inch, as typically measured along its longitudinal axis. Furthermore, the piece of knitted tubing (10) is inverted upon itself at least once along its longitudinal axis to form a plurality of concentric layers of tubing, which are then substantially flattened to form the batt (36). Each of the layers has a similar length and substantially overlaps the other layers. The batt (26) has a top surface (28), a bottom surface (30), and two open ends (22, 24). The top and bottom surfaces (26, 28) are bonded together at the two open ends (22, 24) by a bonding means to maintain the implement (34) substantially flattened. However, the batt (26) retains sufficient loft to function as a personal cleansing implement (34).

Title: Sensor arrays for detecting analytes in fluids
Inventor: FREUND MICHAEL S
IPC: G01N33/02
Filed: 1996-03-26
Abstract: Chemical sensors for detecting analytes in fluids comprise first and second conductive elements (e.g., electrical leads) electrically coupled to and separated by a chemically sensitive resistor which provides an electrical path between the conductive elements. The resistor comprises a plurality of alternating nonconductive regions (comprising a nonconductive organic polymer) and conductive regions (comprising a conductive material) transverse to the electrical path. The resistor provides a difference in resistance between the conductive elements when contacted with a fluid comprising a chemical analyte at a first concentration, than when contacted with a fluid comprising the chemical analyte at a second different concentration. Arrays of such sensors are constructed with at least two sensors having different chemically sensitive resistors providing dissimilar such differences in resistance. Variability in chemical sensitivity from sensor to sensor is provided by qualitatively or quantitatively varying the composition of the conductive and/or nonconductive regions. An electronic nose for detecting an analyte in a fluid may be constructed by using such arrays in conjunction with an electrical measuring device electrically connected to the conductive elements of each sensor.

Title: System and method for reconfiguring a telecommunications network to its normal state after repair of fault
Inventor: WAGNER CLINTON ALLEN
IPC: H04L69/40
Filed: 1996-06-24
Abstract: To revert the topology of a network to its original state after a malfunctioned link (34) has been repaired, an Operation Support System (OSS) (22) sends to each of the custodial nodes (4, 8) and the tandem nodes (14, 16, 18) that form the alternate route respective commands to revert the operation that each node had performed during restoration. The OSS (22) identifies the custodial nodes (4, 8) by the fact that those nodes perform more operations than the tandem nodes (14, 16, 18). The operations that were performed during restoration were recorded. Upon receipt from different nodes that the malfunctioned link (34) has been repaired, the OSS (22) sends to each of the nodes (4, 8, 14, 16, 18) a specific command to perform the inverse of the operations that the node had performed during restoration. The custodial nodes (4, 8) are ordered to perform their inverse operations first so that the repaired link (34) once again connects the custodial nodes (4, 8). A path verification process is next performed to ensure the integrity of the repaired link (34).
