Title: Signal notching system for limiting signal peaks
Inventor: MA ZHENGXIANG
IPC: H04B1/04
Filed: 2000-07-20
Abstract: A signal notching system reduces signal peaks by notching the peak of a signal above a threshold to produce a notched signal. The notched signal is then filtered to produce a resulting signal with a reduced peak amplitude. For example, in an implementation where the signal is represented by signal samples, the peak notching system first locates a peak sample that is beyond a threshold, such as a sample representing a positive peak sample of a peak above the threshold. Once a peak sample is located, the peak notching system adjusts the peak sample by an amount which is a function of the amount that the peak sample is beyond the threshold, effectively creating a notched signal with a one sample notch at the peak. The peak notching system filters the notched signal to fill in the notch to produce a signal with a reduced peak.

Patent CA-2323314-A1 (CA)
Inventor: IH JEONG GUON
IPC: G01K11/24
Filed: 2000-10-17
Abstract: ABSTRACT OF THE DISCLOSURE     A method for optimally determining sensor positions for an acoustic pyrometry, which is capable of obtaining a minimum number of sensors satisfying a given error limit on the basis of an effective independence method and determining positions of the obtained number of sensors suitable for error minimization. A predetermined number of sensors are arbitrarily arranged on sides of a rectangular sectional area to be measured and a transfer matrix is calculated with respect to positions of all the sensors. Then, effective independence values are obtained for respective paths of each of the sensors by performing singular value decomposition with respect to the calculated transfer matrix and a total effective independence value of each of the sensors is obtained by summing up the effective independence values obtained for the respective paths. Subsequently, one having a smallest one of the obtained total effective independence values is removed from among the sensors and the above steps are repeated until the number of the remaining sensors becomes equal to a target value. The target value is set to be larger than a minimum number of the sensors, which is found by calculating variations in a conditional number of the transfer matrix while the sensors are reduced in number and detecting a point where the conditional number increases abruptly.

Abstract: L'invention concerne un procédé analytique de discrimination de données acquises à partir d'échantillons présentant des distributions se chevauchant et d'amélioration et d'évaluation de la validité statistique d'un signal d'hybridation dans les tableaux d'analyse. Ce procédé consiste à convolutionner des données pour en faire deux ou plusieurs signaux et non signaux, représentant des densités de probabilité distinctes, des fluors distincts ou d'autres variables indépendantes convolutionnées. Le système utilise les densités de probabilité pour affecter objectivement des signaux d'hybridation à l'une des distributions modélisées. Des processus ultérieurs évaluent la variabilité inhérente aux tableaux et utilisent les variations ainsi évaluées pour établir des résultats de fiabilité et des limites de confiance pour des tableaux complets d'hybridation et pour des méthodes distinctes d'hybridation au sein des tableaux.

Inventor: MACBETH BRUCE F
IPC: G05F5/00
Filed: 2001-02-06
Abstract: A phase control switch with an RFI suppression inductor includes a first winding on the inductor in series with a triac. A first capacitor is in parallel across the series combination of the first winding and triac. The switch further includes a second winding on the inductor with a second capacitor connected in parallel across the second winding. When the second capacitor and second winding resonate, a Q rise in flux occurs in the inductor core, intercepting the flux in the first winding to produce a greater voltage drop across the first winding and a corresponding decrease in the rate of current rise in the triac. Fewer turns are needed in the first winding for proper RFI suppression, resulting in a smaller device.

Abstract: In an optical waveguide Y junction, comprising an input waveguide path, a split portion having one end smoothly connected to an end of said input waveguide path, and a pair of bifurcated ends, and a pair of output waveguide paths each paving an end smoothly connected to a corresponding one of said bifurcated ends of said split portion, the split portion defines a modified asymmetric Y-shaped waveguide path which is defined by modifying an original symmetric Y-shaped waveguide path having a substantially constant width by removing an asymmetric wedge-shaped section from a side of the split portion interposed between the output waveguide paths. Thus, simply by changing the inner profile of the split portion, a desired uneven split ratio can be achieved without providing a spread out split portion or requiring any abrupt change in the shape of the waveguide path. This contributes to the reduction in the loss of the signal light. Also, a desired split ratio can be readily achieved by suitably changing the dimensions of the wedge-shaped section. In particular, by selecting a wedge-shaped inner profile, the design and fabrication of the junction can be simplified.

Title: Brickless stove
Inventor: PERRAULT CHARLES
IPC: F24B5/02
Filed: 2000-10-24
Abstract: A wood burning stove in the shape of a barrel having both primary and secondary air inlets for supporting clean combustion. Primary air is fed int o the stove from above the door. Secondary air is fed into a heating duct whic h extends along the bottom of the stove to be preheated. The heating duct empties the preheated air into a plenum formed in the end of the stove remot e from the door. Air admitted to the plenum is additionally heated by exposure  to a series of heat transfer fins within the plenum. The shape of the plenum  is such that the velocity of air in the central portion of the plenum is the  slowest, allowing for efficient heat transfer from the plenum walls and fins  to the air passing through. A baffle mounted in the stove above the fire shields the fire from the exhaust outlet. Secondary air is admitted into the  interior of the stove from the plenum from a first set of ports near the top  of the plenum. Additional ports located in the baffle and spaced some distan ce from the plenum feed tertuiary air into the stove at some distance from the plenum. The entire interior surface of the stove is coated with a suitable glass material.
