Patent CA-2160960-A1 (CA)
Inventor: NORIMATSU HIDEHIKO
IPC: H03G3/00
Filed: 1995-10-19
Abstract: In a device for controlling the output power of a power amplifier, an output control signal varies the gain of the power amplifier.  A detector is provided for detecting the output power of the amplifier.  A signal processing circuit receives the output of the detector and a control signal from the outside and controls the gain of the amplifier.  A storage stores detection outputs and output control signals each corresponding to particular power to be output from the amplifier.          The signal processing circuit reads, based on the outside control signal and the output of the detector, corresponding one of the output control signals out of the storage and controls the gain with the output control signal.

Title: Direct lysis buffer and the detection of hiv-1 plasma viremia
Inventor: HENRARD DENIS R
IPC: C12Q1/6806
Filed: 1994-04-28
Abstract: Immunocapture of plasma HIV-1, coupled with direct lysis of the virions and a simplified method of reverse transcription and amplification of the HIV-1 cDNA by the Polymerase Chain Reaction (PCR) represents a rapid and highly sensitive method to monitor HIV-I disease progression.  This method is also less time and labor intensive than quantitative culture. In addition, the development of a method to directly lyse the immunocaptured virions and a simplified single step reverse transcription (RT)/PCR procedure eliminated the need for organic solvent extraction and reduced the number of steps in the procedure. A direct lysis buffer was formulated to isolate plasma HIV-1 RNA for direct use in the RT and PCR reactions, thus eliminating the need for organic solvent extraction and ethanol precipitation.  This resulted in a significant saving of time needed to complete the assay and significantly reduces the possibility of contamination associated with PCR reactions. The immunocapture-RT/PCR assay was used to show that vertical transmission of HIV-1 from a mother to her child depended largely on factors other that viral load. Conversely, the plasma viral load played a significant role in transfusion associated transmission of HIV-1 infection. Finally, the detection and quantitation of plasma associated viral load by immunocapture-RT/PCR may provide an additional marker of disease progression and may aid in determining the efficacy of various HIV therapeutics.

Abstract: An apparatus for testing an integrated circuit includes a bond substrate having a location for an integrated circuit. The location on the bond substrate has a plurality of traces around each location. A first fixture holds the bond substrate in a fixed relation to first fixture and holds the integrated circuit in a fixed relation to the first fixture and the bond substrate. A wirebonder forms wirebonds between the traces and the bond pads. An electrical tester provides electrical signals from the traces to the bond pads to verifying the operation of the integrated circuit. A second fixture lifts the bond substrate while the integrated circuit remains held to the first fixture. A vibrator vibrates the first fixture in relation to the second fixture so that the wirebonds are broken at a predetermined location near the bond pad.

Patent CA-2174015-A1 (CA)
Inventor: KLEIJN WILLEM BASTIAAN
IPC: G10L19/14
Filed: 1996-04-12
Abstract: A decoding method and apparatus for speech coding systems which takes into account the fact that the human auditory system is sensitive to changes in signal characteristics. For example, a sustained distortion of the spectral characteristic of reconstructed speech is usually less perceptible than an objectively smaller distortion which changes as a function of time. This property of the auditory system is advantageously exploited in the design of a speech coding system receiver in accordance with the present invention, by selecting the sequence of decoded speech parameter values on a perceptual basis. Illustratively, the sequence of decoded speech parameter values is selected so as to describe a smooth path through the sequence of Voronoi regions. The distance between successive parameter values is advantageously minimized, under the constraint that the resultant parameter values fall within, or nearly within, the appropriate Voronoi regions. In this manner, a smoother trajectory will result, thereby enabling the receiver to produce a perceptually superior reconstructed speech signal.

Title: Method for Measuring and Extending the Service Life of Fatigue-Limited Metal Components
Inventor: BERKLEY STANLEY G
IPC: G01N23/20
Filed: 1995-05-03
Abstract: Improved methods for managing a population of metal components (10) subject to fatigue failure are provided. The residual compressive stress in the critical surfaces of such components (10), especially in areas of high stress concentration, are measured non-destructively using x-ray diffraction techniques. The measured residual compressive stress is used as a management criteria. A component having a residual compressive stress greater than a predetermined value can be returned to service. However, once the measured residual compressive stress of a component falls below the predetermined value, it can either be removed permanently from service, or it can be reworked to increase its residual compressive stress and then returned to service. Additionally, by measuring the residual compressive stress of an individual component, the remaining service life of that individual component can be estimated. These methods for management of populations of such metal components allow for increasing the service life of the components in a safe and effective manner.
