Title: Appareil et procede de reduction de la diffusion de rayons x et correction de tomographie par ordinateur a faisceau en eventail et tomographie par ordinateur volumique a faisceau conique
Inventor: NING RUOLA
IPC: A61B6/02
Filed: 2003-02-21
Abstract: Dans la tomographie par ordinateur volumique à faisceau conique ou dans les techniques d'imagerie similaires, les effets des diffusions de rayons X sont réduits au moyen d'un filtre à compensation de faisceaux (un filtre noeud papillon), une technique à intervalle d'air, ainsi qu'une grille antidiffusion et sont corrigés au moyen d'un réseau à arrêt de faisceaux combiné à une opération d'interpolation ou de convolution. Des images sont prises avec le réseau à arrêt de faisceau, et un grand nombre d'images sont prises sans le réseau à arrêt de faisceaux. Les images prises avec le réseau à arrêt de faisceaux sont interpolées dans l'espace afin de dévier les informations diffusées, lesquelles sont ensuite interpolées de manière angulaire afin de fournir le plus grand nombre d'images diffusées possible puisque certaines images sont prises sans le réseau à arrêt de faisceaux. Les interpolations sont effectuées par interpolation de fonction spline cubique ou n'importe quelle technique d'interpolation ou opération de filtrage passe-bas (opération de convolution au moyen d'un noyau sélectionné). Chaque image diffusée est enlevée d'une des images correspondantes prises sans le réseau à arrêt de faisceaux afin de fournir une séquence d'images corrigées réparties.

Inventor: SEMPLINER ARTHUR T
IPC: F16B2/18
Filed: 2005-01-18
Abstract: A mechanism for secure engagement of slideable elements in dovetail or similar tracks. The mechanism comprises a pair of plate-like clamping elements adapted to be received within a slide track. The plates are disposed in non-engaging face-to-face relation having a spacer element positioned therebetween adjacent lower edges of the plates. The lower edges project outwardly in relation to the spacer at an angle to engage interior sidewalls of a slide track. A  lever element is adapted to converge the upper portions of the plates in a direction towards the spacer and thereby force the lower edges securely against the slide track. The spacer element can be rotatably mounted and can have a non-circular cross section to facilitate installation and removal of the mechanism.

Abstract: L'invention concerne des procédés et un dispositif de détection d'ischémie myocardique, qui comprennent une détection et l'analyse de changements de la vitesse de conduction électrique dans le coeur en vue de surveiller des changements de l'état du muscle cardiaque et d'indiquer une ischémie possible. La vitesse de conduction ralentit considérablement lorsque l'apport d'oxygène vers le coeur est réduit. L'analyse de la vitesse de conduction électrique peut servir à confirmer un phénomène d'ischémie myocardique de manière plus fiable. On peut surveiller les changements de la vitesse de conduction sur la base du temps de conduction entre des électrodes placées dans les ventricules gauche et droit du coeur. Les électrodes peuvent être endocardiques ou épicardiques. De manière générale, les techniques peuvent comprendre l'application d'une forme d'onde de stimulation sur une électrode, et la détection d'une dépolarisation cardiaque locale sur l'autre électrode afin d'évaluer le temps de conduction.

Patent CA-2504114-A1 (CA)
Inventor: LABALA GUSTAVO FRANCISCO
IPC: F01D19/00
Filed: 2005-04-08
Abstract: A turbine essentially comprises a mechanical generating system including a combustion chamber (2) providing useful mechanical work on a high-speed shaft (8), a speed step-down system (18-20) for receiving rotational energy from the high-speed shaft and an output system including a low-speed shaft (17) receiving rotational energy from the speed step-down system for delivering mechanical from the turbine to a load. Auxiliary systems are kept to a minimum for lubrication, control, operation and start-up functions, thereby making the turbine particularly attractive for light aircraft. The combustion chamber is designed with deflectors (46) generating vortices in a secondary gas flow into the combustion chamber, thereby confining the flame front from penetrating into the cold region (3) of the chamber under variable operating conditions, simplifying cooling of the chamber walls. The high-speed shaft is cantilever mounted on a pair of bearings (9A-9B) in the cold region and is provided with a longitudinal duct and an array of fine orifices (27) in the wall of the shaft which direct pressurized oil in the duct in the form of jets which impinge on the bearings with little relative speed, thereby increasing wetting of the bearing components. Oil is supplied to the duct by means of a positive-displacement pump (23) directly driven by the shaft. The output pressure of the pump provides a signal which is indicative of turbine speed and hence used to control the turbine start-up sequence. The turbine further includes devices for de-coupling vibrations between the three systems thereof, including a loosely mounted spline (16) coupling the high-speed shaft to the step-down system and disk dampening means (41) coupling the step-down system to the low-speed output shaft.

Title: Clothes dryer sensor compensation system and method
Inventor: BEAULAC SEBASTIEN
IPC: D06F34/04
Filed: 2005-05-19
Abstract: A clothes drying appliance has a moisture sensor and a signal acceleration processor coupled to receive and monitor a moisture signal from the moisture sensor. The processor determines signal gradients in the moisture signal and detects either minimums or maximums in the moisture signal when a sign change occurs between two successive signal gradients. The processor uses the detected local minimum or maximum information and the gradient preceding the detected local minimum or maximum to extrapolate a predicted moisture signal value for the clothing articles. The generation of the predicted moisture signal compensates for sensor response time.
