Patent CA-2261188-A1 (CA)
Inventor: XU GANG
IPC: H01P1/18
Filed: 1999-02-18
Abstract: This invention discloses an adjustable, relatively small phase-shiftable network for an antenna array, which can be incorporated into a PCB distribution network.      The network comprises a PCB distribution element (A) comprising a planar dielectric circuit board (2) supporting a pattern of conductive tracks (3).  The conductive tracks and the dielectric circuit board form a transmission line network which splits a signal applied to a signal input terminal (I) into three paths that terminate respectively in three terminals (T, B and C) for feeding the input signal to Top (T), Bottom (B) and Centre (C) sections of a antenna array. The distribution element (A) is supported in a spaced relationship with a conductive ground plane (B). A moveable planar dielectric element (C) having a series of teeth (4, 5) along opposite edges, is slidably mounted over the top surface of the distribution element (A). The moveable dielectric element (C) is supported in a slidable manner by two rods (6, 7) attached to the ground plane (B). By moving the dielectric element, the phases in the top and bottom sections of the antenna array are changed in opposite directions so that the phase shift in one section is increased and the other section is decreased, which causes the radiating beam to tilt.

Title: Improved substrates for human cytomegalovirus protease
Inventor: BONNEAU PIERRE
IPC: C12Q1/37
Filed: 1997-12-23
Abstract: Human cytomegalovirus (HCMV) protease is a slow-processing enzyme in vitro.  Disclosed herein are improved fluorogenic and radiometric peptide substrates for CMV protease. The improved substrates have a typically Tbg-Tbg-Asn(NMe2) sequence replacing the Val-Val-Asn sequence, corresponding to the P4-P2 residue of the maturation site of the enzyme. The incorporation of this new sequence in a variety of substrates has afforded substrates with improved kinetic parameters compared to homologues containing the natural sequence only. For example, the substrate 2-aminobenzoyl-Tbg-Tbg-Asn(NMe2)-Ala.dwnarw.Ser-Ser-Arg-Leu-Tyr(3-NO2)ARG-OH displayed a k out/Km value of 15940 M-1, s-1 i.e. over 60-fold greater than that of the equivalent, non-optimized substrate in identical conditions. The new substrates find use in assays which can evaluate and characterize HCMV protease inhibitors having low nanomolar potency.

Patent CA-2281843-A1 (CA)
Inventor: BAIRD ELDON E
IPC: C07D207/34
Filed: 1998-01-29
Abstract: This invention provides improved polyamides comprising a hairpin loop derived from .gamma.-aminobutyric acid which bind to the minor groove of a promoter regions of a DNA sequence. Binding of the polyamide to the DNA sequence of the promoter region inhibits expression of the requisite gene. The improvement relates to the use of R-2,4-diaminobutyric acid and derivatives of the 2-amino group to form the hairpin loop. The improved asymmetric hairpin provides for tighter binding of the polyamides to the minor groove of DNA and additionally provides an amine function for derivatizing polyamides by, for example, forming amide linkages. Such derivatives may serve to attach detectable labels to the polyamide.

Patent CA-2284327-A1 (CA)
Title: Direct mount snap-in air damper
Inventor: WACH JOSEPH
IPC: F16F9/54
Filed: 1999-09-29
Abstract: The damper includes a damper housing and a piston assembly reciprocating therein. The damper housing includes an attachment device formed of an interior partially circular wall with a triangular cross section thereby forming an interior partially circular apex for engaging a cylindrical boss. This allows the damper to rotate about an axis of the interior partially circular wall and pivot about an axis perpendicular to the rotational axis.      Additionally, the piston assembly includes a detent protrusion formed from a stem supporting a head, the radius of the head being greater than that of the stem. The detent protrusion is engaged by a keyhole-shaped aperture with a first portion with a radius of curvature substantially equal to that of the stem and a second portion with a radius of curvature substantially equal to that of the head. The detent protrusion can therefore rotate within the keyhole-shaped aperture. Additionally, the cap of the damper housing is formed of elastic O-rings to allow the piston assembly to rotate within the damper housing.

Filed: 1999-09-29
Abstract: A nested feed forward distortion reduction system, which reduces the distortion from a main amplifier on a main signal path, uses a nested feed forward arrangement for the correction amplifier to reduce the distortion produced from the correction amplifier. In reducing the distortion from the correction amplifier(s) and using progressively higher quality correction amplifier(s), the nested feed forward arrangement produces an improved, more stable representation of the distortion from the main amplifier, thereby alleviating the need for variable gain and/or phase control in producing amplified signal with reduced distortion.
Patent CA-2286022-A1 (CA)
Inventor: SCHULMAN JOSEPH
IPC: A61N1/365
Filed: 1998-09-11
Abstract: An implantable sensor/stimulator is connectable to a controller using just two conductors, which two conductors carry both operating power and data (data commands and/or measured data) between the sensor/stimulator and control circuit. Each sensor/stimulator may be serially connected to another sensor/stimulator, again using only two conductors, thereby allowing a "daisy chain" of such sensors/stimulators to be formed. Each sensor/stimulator in the daisy chain is individually addressable by the control circuit. Input data is sent to the sensors over the two conductors using a phase-modulated biphasic modulation scheme, which scheme also provides operating power for each sensor/stimulator connected to the two conductors. Output data is sent from the sensors to the controller over the same two conductors using a pulse-position presence/absence modulation scheme. The data transmisssion schemes provide a very high signal-to-noise ratio. Each sensor/stimulator includes a power rectifier circuit, a line interface circuit, a state machine controller, at least one sensor that generates an analog output current as a function of a sensed parameter, a low power current-to-frequency converter circuit, and a counter circuit.
