Title: Serial optical signal distribution system and method, and optical/electrical converter for implementation thereof
Inventor: SOKOLOWSKA EWA
IPC: G02B6/28
Filed: 1995-01-20
Abstract: A  serial  optical  signal  distribution system and method uses first and second coextending optical waveguides.  First and second trains of light pulses are propagated through the first and second optical waveguides, respectively.  A series of first delay lines are distributed along the first waveguide for delaying the first train of light pulses, while a series of second delay lines are distributed along the second waveguide for delaying the second train of light  pulses.    Optical/electrical  converters  are distributed  along the  first  and  second  optical waveguides for receiving a fraction of the delayed first train of light pulses from one of the first delay lines and a fraction of the delayed second train of light pulses from a corresponding one of the second delay lines for producing in response thereto a train of electric pulses.  Each optical/electrical converter comprises a positive power supply line, a negative power supply line, an output line for delivering the train  of  electric pulses,  a  first  photosensitive element connected between the positive power supply line and the output line,  a second photosensitive element connected between the output line and the negative power supply line, a first optical waveguide for supplying to the first photosensitive element the delayed first train of light pulses,  and a second optical  waveguide  for  supplying  to  the  second photosensitive element the delayed second train of light  pulses,  a  capacitive  load  being  connected between the output line and the negative power supply line.

Patent CA-2142711-A1 (CA)
Inventor: RICHTER ANNA
IPC: A61P43/00
Filed: 1993-08-17
Abstract: This invention is a process for the use of a combination of ionizing radiation in conjunction with certain benzoporphyrin derivative compounds (BPD), preferably the compound benzoporphyrin derivative - monoacid ring-A (BPD-MA), to mediate the destruction of diseased or unwanted cells or tissues. Specifically, the invention is a method in which the sensitizer compounds are administered either systemically or locally to the diseased or unwanted tissue and irradiated with ionizing radiation (such as might be produced by a 60Co or x-ray source). The treatment with benzoporphyrin derivative compounds appears to sensitize the target cells or tissues in that those cells do not readily recover from irradiation exposure. In addition, the process may be used to lower the effective amount of radiation applied to a particular tissue target.

Title: System for detecting wood-destroying insect infestations in wood
Inventor: ROBBINS WILLIAM P
IPC: G01V1/00
Filed: 1993-09-16
Abstract: A system for dectecting wood-destroying insects by sensing acoustic emissions generated by the insects as they feed.  The system comprises two acoustic emission sensors, an amplification section, a signal processing section and an indicator section.  The system comes into mechanical contact with the wood to be inspected through the use of a bolt which is inserted into the wood and attaches to an acoustic emission sensor or through the use of an adhesive layer which directly attaches an acoustic emission sensor to the wood. The acoustic emission sensors, are electrically connected to the amplification section which is electrically connected to the signal processing section.  The signal processing section is capable of distinguishing between insect-caused acoustic emissions and noise-caused acoustic emissions detected by the acoustic emission sensors.  The results of the signal processing section are sent to the indicator section.

Title: Electrothermal deicing system
Inventor: WILSON TOMMY MAURICE JR
IPC: B64D15/12
Filed: 1995-04-13
Abstract: An electrothermal deicing system for an airfoil includes a plurality of cycled ice shedding zones and anti-icing parting strips, with a temperature sensor attached to the inner surface of the airfoil skin over a primary shed zone to detect the environmental conditions of the skin over the primary shed zone.  The primary shed zone is energized, and the temperature sensor provides a temperature signal to a controller which determines the time tPEAK it takes to reach a predetermined peak temperature.  The tPEAK time is indicative of the environmental conditions and is utilized by the controller to: set the gate on time of the remainder of shed zones which are cycled according to the a predetermined sequence; and set the dwell time between temperature cycles.  In this manner the heater elements are continuously monitored and cycled in accordance with true environmental conditions.

Patent CA-2165229-A1 (CA)
Inventor: MEYERS MARTIN HOWARD
IPC: G10L17/06
Filed: 1995-12-14
Abstract: The present invention provides a method and apparatus for measuring at least one signal characteristic.  Initially, a set of features is selected whichcharacterize a signal.  An intelligent system, such as a neural network, is trained in the relationship between feature sets and signal characteristics. The selected feature set is then extracted from a first input signal.  The extracted feature set from the first signal is input to the trained intelligent system.  The intelligent system creates an output signal based on the feature set extracted from the first input signal.  This output signal is then used to characterize the input signal.  In one embodiment, the invention assesses voice quality, typically as expressed in MOS scores, in a manner which accurately corresponds to the analysis of human evaluators. For voice signals processed by voice coders, the present invention provides a measurement technique which is independent of various voice coding algorithms and consistent for any given algorithm.

Title: Polymere d'alcool de vinyle
Inventor: FUJIWARA NAOKI
IPC: C08F216/06
Filed: 1995-06-05
Abstract: Polymère d'alcool de vinyle présentant un groupe hydroxyalkyle C¿2?-C¿20? dans la chaîne latérale. Ce polymère présente une excellente stabilité thermique, car la température entraînant une perte de poids de 5 % est supérieure à 300 ~C. Les polymères d'alcool de vinyle hydrosolubles conventionnels provoquent une formation de bulles si importante à l'état dissous dans l'eau, lorsqu'ils présentent une forte activité de surface, que leur application industrielle pose des problèmes. Par rapport à ces polymères, le polymère de l'invention, même s'il est hydrosoluble, provoque peu de bulles à l'état dissous dans l'eau en dépit de sa forte activité de surface, ce qui lui confère de larges possibilités d'applications industrielles. Il peut être utilisé sous forme de résine thermoplastique et de stabilisateur de dispersion, et peut être appliqué sous forme de tensioactif, d'agent de modification du papier, par exemple d'agent de couchage de papier, d'additifs pour papier et de liant de pigment, d'adhésif pour le bois, le papier, les feuilles d'aluminium et les matériaux inorganiques, de liant de non-tissé, de matériau de revêtement, d'agent de parage, d'agent de traitement de fibre, d'agent d'encollage pour fibres hydrophobes par exemple de polyester, de film, de feuille, de bouteille et de fibre.
