Patent CA-2181244-A1 (CA)
Inventor: OLGAC NEJAT
IPC: F16F7/10
Filed: 1995-09-06
Abstract: Vibrations are dampened by determining two principal frequencies of excitation for the structure and coupling thereto a damping member to produce an absorber. The spring damper characteristics of the absorber are determined at these frequencies and the displacement of the damping member is monitored. The monitored displacement of the damping member is processed together with the spring damping characteristics of the absorber to output a signal. This produces two frequencies of vibration in the damping member substantially equal to the determined frequencies of excitation and thereby produces a resonance of the damping member at the determined frequencies of excitation. The resonance is effective to damp the vibrations at the determined frequencies of excitation.

IPC: C07K14/575
Filed: 1995-02-28
Abstract: The present invention relates to a method of accelerating the onset of puberty in avians, especially ratites and psittaciformes, by administering a heterologous protein comprising inhibin, or a fragment thereof, and a carrier protein. The present invention also relates to a method of increasing egg production in animals, particularly birds, more particularly ratites, via the administration of the heterologous protein. This invention further relates to the heterologous protein and a method for producing the heterologous protein. The heterologous protein can be either inhibin conjugated to the carrier protein or inhibin fused to the carrier protein.  The method of producing the fused heterologous protein comprises inserting double stranded cDNA encoding inhibin, or a fragment thereof, into a vector which encodes a carrier protein such as maltose binding protein or bovine serum albumin.  After inserting the vector into an expression system, the fused heterologous protein is expressed by the system.After purifying the expressed heterologous protein, an effective amount of the protein is administered to an animal such that an immunological response occurs in the animal against the heterologous protein.

Abstract: Digitized information can be automatically re-edited to alternate sequence characteristics or lengths with a marker file provided to a computer. Information that can change the characteristics of the digitized information is contained in the marker file and is a variable that can automatically control the digitized information stored in the memories. The disclosed procedure involves assigning identification markers for points in a digital information file of a certain length containing digitized information.  The markers may be assigned relative to the frame number from the beginning of the digital information file. The sections defined by the markers are then re-assembled automatically in other orders, output characteristics or in other sequences to create a new digital information file of different structure, characteristic and length.  The technique is especially useful for producing musical rearrangements in the cathode ray tube screen and audio synthesizers.

IPC: G01V7/16
Filed: 1995-08-30
Abstract: The invention relates to a device and a process for gravitation measurement with an acceleration sensor fitted on a moving support, a satellite navigation receiver and a computing unit in which use may be made of several acceleration sensors instead of one for vector gravimetry, the satellite navigation receiver must show the spatial location as well as the position in order fully to indicate the inertial acceleration and finally the computing unit may finally be used off-line for the combination of the measured total and inertial acceleration to determine the gravitation. The numeric filtering of the accelerations measured is considerably improved by the drafting of filter coefficients best suited to the stochastic properties of the gravitational field over a "physically blind" low-pass filtration. The invention makes it possible to use simpler and more economical acceleration meters, to find the vector gravimetry, i.e. the full gravitation vector, and determine finer structures of the earth's gravitational field by aircraft/ship gravimetry.

Filed: 1997-04-11
Abstract: A computer peripheral device to attach the multimedia loudspeakers to the computer display monitor consists of two plates which are stuck to the sides of the monitor and that of the speakers by self-adhesive pads. One of the plate is a metallic plate which is ferromagnetic. The other is a magnet plate, such as a thin multi-pole rubber-sheet magnet.  When the two plates are in contact, they will attract to each other, thus allowing the speaker to attach to the sides of the display monitor.          Due to the fact that the speakers are hold into place by magnetic pads, the device is very simple and the user can install the speakers easily without requiring any tool.          Furthermore, due to the fact that only a smaller portion of the  metallic plate is needed to hold the magnetic pad, the users can attach the speakers at any desired level along the side of the display monitor or tilt them at any angle for optimum sound transmission.

Title: Dual chamber pacing system and method with automatic adjustment of the av escape interval for treating cardiomyopathy
Inventor: WARKENTIN DWIGHT H
IPC: A61N1/362
Filed: 1996-01-26
Abstract: There is provided a dual chamber pacemaker system and method for ventricular pacing to provide therapy for a patient with cardiomyopathy, this system being characterized by automatically adjusting the AV escape interval so that ventricular pace pulses are delivered at an AV delay which is optimized for HOCM and/or dialated cardiomyopathy therapy. The pacemaker system continually obtains and stores representations of a QRS wave characteristic such as duration, derived either directly from the QRS signal or from an FFRS signal, and compares duration data from one or more cycles to prior stored duration data. The system then adjusts the AV interval as a function of the duration comparison, and the direction of the last adjustment of AV escape interval. By this means, theAV escape interval is maintained at or just short of the onset of fusion, thereby automatically providing for optimally lengthened AV escape intervals consistent with full capture by the delivered ventricular pace pulse.

IPC: H01R24/64
Filed: 1997-12-17
Abstract: A high frequency electrical connector having a dielectric block onto which a terminal array of four pairs of electrical conductors are connected, the resulting assembly residing in a jack frame housing configured to removably receive a mating plug. The connector has a planar spring contact region for electrically contacting a corresponding planar contact region of the mating plug, a curved forefront region whereat non-electrical contact cross-overs of the terminal array conductors occurs, and a planar back region where reverse crosstalk is generated. The connector substantially compensates for crosstalk generated at the mating plug and connector contact regions. The configuration of the planar contact region of the mating plug and planar spring contact region of the connector is dictated by industry standards. To generate a sufficient reverse interference to cancel the crosstalk generated in these dimension-regulated parts, an "equivalent distance" of the planar back region sufficient to generate a reverse crosstalk that substantially eliminates the crosstalk generated in the contact regions of the mating plug and connector is provided. This equivalent distance is typically greater than the length of the planar spring contact region since the parallel mating plug conductors and their proximity to the spring contact region contribute to the crosstalk generated by the substantially parallel conductors of the terminal array in the spring contact region. To provide this equivalent distance, the non-contact cross-overs of the conductors are located immediately adjacent to the source of crosstalk without interfering with the industry standard dimensions.
