Patent CA-2295342-A1 (CA)
Inventor: MOORE PHILIP J
IPC: G01R31/08
Filed: 2000-01-12
Abstract: Faults on power lines are detected by measuring the voltage and current at one end of a power line and uses these measurements, together with values of series and shunt parameters of the line, to calculate values of voltage and current at an intermediate point on the line - the so-called "reach point". At least the calculated voltage is used to determine whether a fault lies within a particular zone on the line. The calculation utilizes a value of a derivative of said measured current with respect to time and is able to take into account the sectioning of a line into discrete lengths corresponding to, for example, overhead and cable sections. To increase accuracy, the line or each discrete section of the line is conceptually divided into subsections each having their own parameter values.  In a second aspect of the invention, detection of whether a fault lies within a particular zone involves the measurement of first-end voltage and current both before and after the fault, the calculation of the complex impedance between an intermediate point of the line and a reference point, normally earth, using these measured values and values relating to line parameters and to a source impedance of the second end of the line, and the determination of the sign of the complex impedance.

Abstract: L'invention concerne un procédé d'amplification d'une séquence nucléotidique par un procédé faisant intervenir une réaction nucléotidique en chaîne (p. ex. une réaction en chaîne de polymérase ou de ligase). Le processus fait intervenir des cycles récurrents d'étapes qui sont les suivantes: dénaturation nucléotidique et synthèse nucléotidique, la synthèse étant effectuée sous l'action d'une enzyme (une polymérase ou ligase nucléotidique). La dénaturation et la synthèse sont effectuées dans différentes zones de réaction de dénaturation et de synthèse et, pendant les cycles récurrents, l'enzyme est maintenue isolée de la zone de réaction de dénaturation. Les conditions ou les réactifs nécessaires à la dénaturation sont maintenus isolés de la zone de réaction de synthèse dans la mesure où les réactifs et les conditions nécessaires à la dénaturation n'empêchent par que la réaction de synthèse ait lieu dans une large mesure. L'utilisation de zones séparées pour la réalisation des étapes de réaction permet l'utilisation dans la réaction d'une enzyme qui est détruite ou dégradée par les réactifs et les conditions nécessaires à la dénaturation (p. ex. une polymérase ou ligase thermolabile ou alcalilabile). En outre, l'utilisation de multiples zones permet l'emploi d'un matériel bon marché pour mettre en oeuvre ce procédé. L'invention concerne en outre un appareil permettant de mettre en oeuvre ce procédé.

Title: System for simultaneously imaging vehicles and their license plates
Inventor: ALVES JAMES FRANCIS
IPC: G03B15/02
Filed: 2001-01-10
Abstract: A vehicle video imaging system comprises a white-light LED array for illuminating retro-reflective painted parts of a vehicle's license plate and a polarizing filter for illuminating any non-retro-reflective license plate paint and the vehicle itself. A video camera with a polarizing filter turned 90° relative to the one in front of the flash receives the illuminated image of the vehicle and its license plate. The retro-reflective paint of a license plate will return polarized light as it is received, so the white-light LED array will provide all the illumination needed by the camera. The polarizing filters will combine to block out most of the light from the flash that was returned still-polarized by the retro-reflective-paint license plate. All other surfaces that do not have retro-reflective paint will bounce-back and scatter the light from both the polarized flash and non- polarized light.
