Patent CA-2296209-C (CA)
Inventor: PAYER DANIEL G
IPC: H04L25/06
Filed: 2000-01-17
Granted: 2003-04-01
Abstract: A method and apparatus for dynamically generating multiple level decision thresholds of an M-ary demodulated signal for decoding the signal. The threshold values are obtained by obtaining the maximum and minimum peak values of the demodulated M-ary signal, averaging these peak values and subsequently processing these averaged values to establish the threshold for the particular M-ary signal. Infinite impulse response filters may be advantageously used in the averaging process and these filters may be preloaded with maximum and minimum peak values such that decision threshold levels may be generated immediately after receiving the M-ary demodulated signal.

Abstract: A method and apparatus is disclosed for enhanced laser-induced plasma spectroscopic analysis of unknown heterogeneous materials. The apparatus has high power pulsed lasers with their beams focused on the material, typically two collinear lasers providing two pulses in the ultraviolet and in the near infrared spectral area. The first laser pulse vaporizes a small volume at the surface of the material and produces a plasma which is subsequently enhanced by the second laser pulse. The optical emission of the plasma is analyzed with a collinear optical spectrometer. The pulsed spectrum is detected by a gated photodiode array detector or by an array of photomultipliers each individually positioned to detect a line emission representative of a given element present in the material. The combination of the two laser pulses, appropriately synchronized, provides a plasma emission that is significantly stronger than a single laser pulse of the combined energy of the two pulses.

Abstract: A control system is provided for a tracked vehicle drive/steering system having an engine driven hydraulic steering pump which drives a hydraulic steering motor.  The steering pump is responsive to steering control signals representing a status of an operator manipulated steering wheel. The steering motor provides an input to a differential track drive mechanism which responds to manipulation of the steering wheel and drives left and right tracks to turn the vehicle. The control system includes a control unit which receives signals from an engine speed sensor, a steering motor rotation speed and direction sensor, and the steering control signals. The control unit calculates a motor speed threshold value as a function of sensed engine speed and steering control signals, and generates a fault signal as a function of a relationship between the steering motor speed signal and a motor speed threshold value. The control unit generates an overspeed fault signal when the steering motor speed signal is greater than the motor speed threshold value or less than a negative motor speed threshold value, and generates a data conflict fault signal when the steering motor speed signal is less than a negative minimum motor speed threshold value or greater than a minimum motor speed threshold value. The control unit, when the vehicle is not being commanded to turn by the steering control signals, generates a minimum threshold value, and generates an overspeed fault signal when the motor speed signal is greater than the minimum threshold value or is less than a negative minimum threshold value.

Abstract: Center filler plates for mounting on draft sills of railway car underframes are disclosed. The center filler plates have four pockets surrounding a hub. The pockets are shallower than in the prior art, and the walls defining the pockets meet in radii having larger radii of curvature than in the prior art. The shallower pockets and larger radii of curvature facilitate removal of the casting from the molding sand in the cope and drag sections of the mold. The formation of burned-in sand is limited in the present invention, and any burned-in sand that does form is also more easily removed from the center filler plates of the present invention. The base portion of the center filler plates is not as high as in the prior art. The ribs of the center filler plate and the walls of the hub are thicker than in the prior art to provide the needed strength to the center filler plates. In one embodiment, the ribs taper toward the hub, and the hub is shorter than the surrounding web; a tool may be inserted through the kingpin hole, expanded to bear against the tapered surfaces of the ribs; a machine may be used to lift the center filler plate and move it into position on the draft sill. The tool may then be contracted and removed, and the center filler plate may be secured to the draft sill through welding or other techniques.

Abstract: MRA data is acquired from a large region of interest by translating the patient to successive stations at which successive portions of the three- dimensional MRA data set are acquired. Patient movement is chosen to track a  bolus of contrast agent as it passes through the region of interest and a 3D  acquisition is performed at a succession of stations. The order and shape in  which k-space is sampled differs from station-to-station to achieve maximum image contrast.

Abstract: La présente invention permet d'améliorer l'efficacité du codage vidéo des scènes de mouvement rapide en invalidant de façon adaptative un paramètre qui indique si les données de texture et de mouvement sont codées pour un macrobloc. Le paramètre COD (non codé) est invalidé lorsque le nombre de macroblocs dans lesquels pratiquement toutes les données de texture et de mouvement sont nulles est inférieur à un certain seuil. Ceci permet de réduire le nombre de bits nécessaire pour coder une image vidéo entre trames dans une séquence vidéo à mouvement rapide et présentant de nombreuses modifications d'une trame à l'autre. On utilise également le codage de chrominance de bloc pour déterminer la manière d'effectuer le codage entropique du codage de luminance de bloc. Dans les blocs entre trames, si les blocs de chrominance sont codés, il est probable que les blocs de luminance seront codés également. C'est pourquoi on utilise le codage de chrominance de bloc pour choisir la table de codage entropique appropriée au codage de luminance de bloc.

Title: Formed safety bottom for a candle can
Inventor: PETERSON RICHARD L
IPC: F23D3/16
Filed: 2000-12-29
Granted: 2008-02-05
Abstract: This invention is directed to a candle can of the type normally filled with an ignitable fuel. The candle can includes an upstanding continuous sidewall that is integrally coupled to a stamp formed candle can bottom structure at an outer periphery of the candle can bottom structure. The integral coupling of the sidewall to the bottom structure establishes a can support ring to engage a support surface. The stamp formed can bottom structure is so formed as to provide within the can an internally upwardly directed dome upon which a candlewick carrying element may be securely located within a dish shaped indentation in an apex region of the dome. In a preferred embodiment of the invention the intersection of the sidewall and the upwardly directed dome of the can bottom structure establishes an annular internal volume of fuel separated by the dome from a candlewick flame near the end of both the candlewick life and the supply of fuel. This just described arrangement of an annular internal volume of fuel which surrounds the dome minimizes flash-over while also creating the annular ring supporting surface for the candle can base which reduces heat transfer from the candle fuel and flame to the support surface.

Abstract: A floating rig or structure for drilling in the floor of an ocean using a rotatable tubular includes a seal housing having a rotatable seal connected above a marine riser fixed to the floor of the ocean. The seal rotating with the rotating tubular allows the riser and seal housing to maintain a predetermined pressure in the system that is desirable in underbalanced drilling, gas-liquid mud systems and pressurized mud handling systems. A flexible conduit or hose is used to compensate for the relative movement of the seal housing and the floating structure since the floating structure moves independent of the seal housing. A method for use of the system is also disclosed.
