Patent CA-2154879-A1 (CA)
Title: Anti-theft method and apparatus for locking the brakes of a vehicle
Inventor: MACWILLIAM MARK WAYNE
IPC: B60R25/08
Filed: 1994-01-25
Abstract: An anti-theft device is installed in a vehicle brake line which carries braking fluid. The device includes a ball-valve rotatable between a first position in which it blocks fluid flow, and a second position in which it permits fluid flow in both directions. The ball-valve is resiliently urged against a valve seat such that, even when closed, it can function as a check-valve, allowing braking fluid to flow only toward the wheels. The valve can easily be switched between the first and secondpositions, and can be locked in the first position. By allowing braking fluid to flow only toward the wheels, the wheel brakes, once applied, cannot be released.

Title: Method to Operate an Incoherently Emitting Radiation Source
Inventor: VOLLKOMMER FRANK
IPC: H01J65/00
Filed: 1994-04-05
Abstract: A method to operate an incoherently emitting radiation source, in particular a discharge lamp, which transmits UV, IR or VIS  radiation.  The discharge is generated by means of a train of voltage pulses, interrupted by idle times, inside a discharge vessel; electrodes dielectrically impaired on one or both ends can be used.  By a suitable choice of the filling, the electrode configuration, the sparking distance, the type and thickness of the dielectrics, the time-dependent voltage amplitudes, and the pulse and idle times, efficiencies in UV generation of 65% and more are attained.

Inventor: HEIKKILA SAMULI
IPC: H02P21/14
Filed: 1994-02-24
Abstract: The invention relates to a method for determining an estimate for the stator flux of an asynchronous machine when the supply frequency ?s, stator inductance Ls, stator resistance Rs or an estimate Rse therefor, and short circuit inductance .sigma.Ls are known, in which method the stator current ?s and stator voltage ?s are measured, a difference voltage is calculated by subtracting the product of the stator resistance or its estimate and the stator current from the stator voltage, and said difference voltage is integrated in relation to time to obtain a stator flux estimate ?se. To improve the accuracy of the estimate, prior to the integration a correction term based on the feedback stator flux estimate ?se and being proportional to the product of the difference variable .epsilon. and the direction vector ? given therefor is subtracted from said difference voltage, said difference variable being determined from the equation: (?se-Ls?s) . (?se-Ls?s) = .epsilon. and the direction vector ? being formed from the feedback stator flux estimate ?se by turning it for the angle .theta. which is dependent on the operational mode of the machine.

Patent CA-2173446-A1 (CA)
Title: Ultrasound catheter system having modulated output with feedback control
Inventor: NITA HENRY
IPC: A61B17/32
Filed: 1994-09-30
Abstract: A method and apparatus for driving an ultrasound transducer (14) coupled to an ultrasound disposed within an elongate catheter (10) has a modulated output and utilizes feedback control. A modulating signal varying in amplitude and continuous in duration modulates an ultrasound transducer drive signal. The resulting modulated ultrasound drive signal is likewise continuous in duration such that it lacks the abrupt accelerations which cause stress to be applied to the ultrasound transmission member in prior art devices. The current of the modulated drive signal is monitored and the voltage thereof is varied in response to changes in the current in order to provide feedback control. A transmission member breakage alarm provides an indication of transmission member breakage in the event that any comparison of the drive energy to the feedback control signal indicates that the desired ultrasonic vibration has been reached at a drive energy level less than the minimum drive energy level typically desired for such desired ultrasound vibration when the ultrasound transmission member is intact.

Patent CA-2177092-A1 (CA)
Inventor: WEBER ROY PHILIP
IPC: H04M15/00
Filed: 1996-05-22
Abstract: Entities who normally are financially responsible for calls made by them have their calls paid for by a sponsor when they are selected by the sponsor to be included in a "family ring" and they make calls to other entities that are included by the sponsor in the family ring. This capability is achieved with the aid of a database node which maintains information about the identity of members in the family ring. Operationally, in accordance with one embodiment, any member of the family ring who wishes to callanother member of the family ring calls a pre-designated number that connects the calling party to a database node. The database node interacts with the calling party by first determining whether the calling party is a member of the family ring, and when the calling party is authenticated, the database node responds to information that identifies a selected called party who is also a member of the family ring. The database nodeperforms a translation, as necessary, and informs the telecommunication network of the destination desired by the calling party. In response, the telecommunication network connects the calling party to the called party.

Patent CA-2187521-A1 (CA)
Inventor: HUGHES JONATHAN RENNIE
IPC: G02F1/133
Filed: 1995-04-10
Abstract: L'invention concerne un écran à cristaux liquides ferroélectriques présentant des niveaux de gris répartis uniformément. L'invention a pour objet un écran à cristaux liquides ferroélectriques bistables formé par une couche de matière chiral smectique à cristaux liquides située entre deux parois de cellules. Les parois portent par exemple des électrodes lignes et colonnes permettant de constituer une matrice en x, y de pixels adressables et ont subies un traitement de surface pour assurer un fonctionnement bistable. Chaque pixel peut être sous-divisé en sous-pixels, générant ainsi une pondération spatiale de l'échelle de gris. La pondération temporelle de l'échelle de gris est obtenue par basculement d'un pixel de l'état foncé pendant une période T1 à l'état clai pendant une période T2. Lorsque T1 et T2 ne sont pas égales, on obtient quatre échelles de gris différentes, à savoir foncé, gris foncé, gris clair, et clair. La présente invention permet d'obtenir une répartition uniforme des niveaux de gris par adressage de chaque pixel au moins deux fois pendant la durée d'une trame. Chaque pixel est mis à blanc et excité au moins deux fois pendant chaque trame; la variation de la durée de la mise à blanc par rapport à la durée d'excitation en quatre périodicités différentes, produit les niveaux d'échelle de gris désirés. La combinaison des pondérations temporelle et spatiale permet d'augmenter le nombre d'échelles de gris réalisables. De plus, on peut régler l'intensité des ous-pixels adjacents les uns par rapport aux autres afin de faire varier la taille apparente du plus petit sous-petit sous-pixel, ce qui utile lorsque la taille du sous-pixel est proche des tolérances de fabrication.

Title: Idle speed control for internal combustion engines
Inventor: MELBOURNE KEITH
IPC: F04D29/02
Filed: 1995-06-29
Abstract: A method of controlling the idle speed of an engine of a vehicle. In the case of a vehicle having an automatic transmission, the method includes increasing the engine speed from a first idle speed to a second idle speed higher than said first idle speed in response to a driver originating indication independent of an acceleration control of the vehicle that vehicle motion is desired, the higher second idle speed being set to achieve a desired level of vehicle creep. The acceleration control of the vehicle is typically an accelerator pedal which is depressed by the driver to accelerate the vehicle. In the case of a vehicle having either a manual or automatic transmission, the method includes increasing the engine speed from a first idle speed to a second idle speed higher than said first idle speed in response to the release of a brake of the vehicle brake system. The engine idle speed is returned to the first idle speed when the brake is re-engaged.
