Inventor: KAFRI ODED
IPC: G08G1/02
Filed: 1997-07-11
Abstract: Système automatique de surveillance de la circulation destiné à faire respecter le code de la route et les règlementations et destiné à la surveillance de la circulation à des fins générales, comprenant un nouveau capteur passif placé dans la chaussée qui détecte avec précision la cinématique de véhicules qui roulent. Ledit capteur comporte un détecteur protégé par une enveloppe qui est encastrée dans une ouverture ménagée dans la chaussée, ledit détecteur étant en mode d'écoute permanent. Lorsque les roues d'un véhicule qui passe entrent en contact soit avec l'ouverture ménagée dans la chaussée, soit avec l'enveloppe, soit avec les deux, l'impact mécanique qui en résulte génère une perturbation qui déclenche le détecteur. Une unité de traitement dudit système automatique de surveillance de la circulation enregistre le signal détecté par le détecteur et analyse ses caractéristiques temporelles pour déterminer le moment précis de l'impact.

Title: Animal embryo commercial production by using in vitro fertilization technology
Inventor: SEE-HSUN YAU
IPC: A61D19/00
Filed: 1999-05-10
Abstract: For many years, industrialized nations have been using biotechnology for both agriculture and animal husbandry. Embryo transfer in cattle becomes one of the most exciting and progressive procedures available to today's animal producers. With conventional production, the average cow produces six to seven calves in her lifetime.  Embryo transfer can increase her reproduction efficiency to numerous calves per year, thin increasing the selection opportunities many times. Along with artificial insemination, embryo transfer offers progressive producers fascinating genetic opportunities. Bovine are one of the major food sources for human and the productivity rate of domestic animals is a very influential factor for many developing countries. In countries such as the United States, Canada, and Australia, embryo transfer is a popular and standard technique for the improvement of bovine breeds. All the current commercial available frozen cattle embryos are produced by method combines techniques include artificial insemination (AI), pregnancy detection, embryo flushing and embryo freezing. The idea behind this technique is to obtain a pregnant cow first, by means of AI. Then embryo inside the cow is "flushed"" out by buffer solution. Microscope is used to locate the embryo from the flushed solution. And the final stage is to freeze the embryo for storage or to perform embryo transfer. IND Lifetech Inc. has a unique method to mass product low-cost embryo for commercial purpose.

Patent CA-2273225-A1 (CA)
Inventor: GALLAGHER PATRICK J
IPC: F41H11/12
Filed: 1997-12-02
Abstract: A hand-held prodder (1) capable of distinguishing inert rock from potentially hazardous landmines or other unknown objects. The prodder comprises a rod (2) which is placed into contact with an object (8). A high frequency acoustic or incident wave is introduced into rod (2) and travels along the rod to the object (8) where it is reflected back towards the piezoelectric crystal (10).  The piezoelectric crystal converts the reflected wave to an electric signal and a signal processor (13) determines values representative of the frequency-time-amplitude characteristics of the object. Different materials exhibit different mechanical impedances and frequency damping characteristics. By comparing reflected wave characteristics to pre-determined characteristics for known materials, inert rocks and potentially hazardous plastic or metallic objects are distinguishable. Visual or audible signals inform the user whether rock (safe) or unidentified or known hazardous object were contacted.

Patent CA-2279751-A1 (CA)
Title: Combined trigger and concealing device for a sprinkler head
Inventor: FRANSON SCOTT T
IPC: A62C37/14
Filed: 1999-08-06
Abstract: A combined trigger and concealing device for an automatic sprinkler head comprises a first plate attached to a second plate by a heat fusible material in a partially overlapping manner. Each plate is formed with an aperture which receives an actuator depending from the bottom of the sprinkler head. The trigger device depends a preselected distance from the bottom of the sprinkler head body and has an outer dimension which causes the trigger device to conceal the internal components of the sprinkler head from view. An annulus defined between the periphery of the device and the bottom of the sprinkler head permits heat energy to be received by the inner surface of the trigger device.  Conduction of heat energy from both the inner and outer surface of the trigger device permits the heat fusible material to be expeditiously raised to the preselected separation temperature. This uniform thermal conduction minimizes the response time of the automatic sprinkler head while maintaining a highly aesthetic appearance.

Title: Method and device for time domain demultiplexing of serial fiber bragg grating sensor arrays
Inventor: COOPER DAVID J F
IPC: G01K11/32
Filed: 1999-10-08
Abstract: The present invention provides a method and device for to implement time division multiplexing of a fiber optic serial Bragg grating sensor array containing more than one Bragg grating. The device provides a pulse read-out system that allows for a reduction in system noise and an increase in sensor resolution and flexibility. The optical signals reflected from the Bragg grating sensors are gated by an electronically controlled optical modulator before any wavelength measurement is performed to determine the sensor information. This offers significant advantages since the sensor information is encoded into the wavelength of the optical signal and not its intensity. Therefore the sensor signal information is not distorted by the gating. Since the gating or switching of the optical modulator between transmission and attenuating states is performed on the optical signal, the speed of the electronic processing needs only to be performed at the speed of variation of the sensor information and the choice of methods of wavelength measurement is not influenced by the gating action.
Patent CA-2291045-A1 (CA)
Title: System and method for providing a busy signal to a communication
Inventor: MOQUIN THOMAS JOSEPH
IPC: H04Q3/00
Filed: 1998-06-30
Abstract: A system and method to provide a busy signal to a communication without a terminating network element providing answer supervision and without the originating caller associated with the communication being charged for the communication. A communication that has been forwarded over an integrated services digital network (ISDN) interface connection from a central office to a terminating network element for further routing of the communication to a terminating unit is accepted at the terminating network element and an ISDN  interface connection is made, but answer supervision with respect to the communication is not provided. Upon a determination that the terminating unit to which the communication would otherwise be forwarded is busy, the terminating network element provides an ISDN release complete message with respect to the communication to the central office. The ISDN release complete message instructs the central office to play a busy signal to the communication. The terminating network element also releases the ISDN  interface connection to the communication. In response to receipt of the ISDN  release complete message from the terminating network element, the central office plays a busy signal to the communication.

Patent CA-2303795-A1 (CA)
Inventor: TODORSKI ZENON
IPC: C10B53/02
Filed: 2000-03-27
Abstract: This invention relates to a new continuous method of pyrolysis of wood chips or compacted cellulosic materials in the absence of oxygen. Positive displacement of chips, by means of a screw conveyor, brings them into contact, in a countercurrent manner, with the newly formed reactants, which are cooled instantaneously, as they are withdrawn from the reactor. Heating of the charge is thus partially affected. The fast removal of methanol from the pyrolysis zone and its subsequent cooling by the chips prevents its decomposition .Final heating of the charge is done by means of hot internal combustion engine exhaust gases, which are passed through the jacket surrounding the screw conveyor. The partially cooled exhaust gases are,then contacted with the chips in the preheater in a countercurrent manner, before being exhausted into the atmosphere.
