Patent CA-2236907-C (CA)
Inventor: SHAFFER SHMUEL
IPC: H04N19/00

Granted: 2001-09-11
Abstract: A method and system in which lip synchronization is restricted to a single system in a multiple system communication of video data and audio data. In the preferred embodiment, the receiving system synchronizes video and audio signals for presentation. The originating system forms and processes video and audio signals separately. For many systems, the processing involves dissimilar delays. Consequently, when the information is transmitted through a network to the receiving system, the video and audio data is nonsynchronous. The originating system provides delay information that is indicative of the dissimilarity of video and audio processing time at the originating system.  The delay information is utilized at the receiving system to determine an adaptive compensation delay for introduction at the appropriate video or audio processing path. By providing a single compensation delay for multi-system communications, the total delay is potentially reduced.

Abstract: Un dispositif amélioré de raccord d'un arbre d'entraînement, comprenant un nouveau boulon de cisaillement pour raccorder deux extrémités ou brides du dispositif de raccord de l'arbre d'entraînement de façon à ce que les parties séparées du dispositif de raccord de l'arbre d'entraînement soient raccordées solidement l'une à l'autre tout en pouvant se désunir l'une de l'autre et tourner indépendamment l'une par rapport à l'autre en cas d'une surcharge sur l'arbre d'entraînement ou le dispositif de raccord de l'arbre d'entraînement. Le boulon de cisaillement est à deux extrémités (c.-à-d., fileté aux deux extrémités) et comporte un épaulement à chaque extrémité. Les filets à chaque extrémité permettent aux deux brides du dispositif de raccord de l'arbre d'entraînement d'être tractées ensemble à une distance prédéterminée, qui, conjointement avec un point de cisaillement, est établie par la distance entre les épaulements opposés des deux côtés du boulon de cisaillement. De plus, les brides du dispositif de raccord de l'arbre d'entraînement sont conçues pour recevoir les boulons de cisaillement à l'intérieur d'ouvertures encochées. Les boulons de cisaillement sont conçus de façon à comporter une section plate qui s'ajuste dans les encoches du dispositif de raccord de l'arbre d'entraînement, de façon à ce que l'ajustement du boulon de cisaillement dans le dispositif de raccord de l'arbre d'entraînement ainsi réalisé empêche le boulon de cisaillement de tourner à l'intérieur de l'encoche du dispositif de raccord de l'arbre d'entraînement. En empêchant les boulons de cisaillement de tourner, cet ajustement permet d'installer et de retirer facilement les écrous filetés sur les boulons de cisaillement.

Abstract: On détermine les paramètres d'écoulement d'un fluide dans un ensemble distributeur de fluide en surveillant les réponses en pression et en traitant lesdites réponses en même temps que les informations concernant l'écoulement du fluide. Dans l'un des aspects, un processeur commande la pompe de façon qu'elle pompe certaines quantités de flux en fonction d'un code pseudo-aléatoire. Des parties du signal de pression détecté obtenu sont ensuite décodées en fonction du code pseudo-aléatoire. Une estimation de la pression d'équilibre est générée à partir des valeurs de pression décodées, tandis qu'une somme des échantillons de pression est générée à partir des signaux de pression non décodés. La résistance à l'écoulement du fluide dans le système est déterminée à partir de la pression d'équilibre estimée et de la somme des pressions. Pour des débits faibles, un processeur commande la pompe de façon qu'elle pompe le fluide réparti en une série de bolus fluidiques, chaque bolus étant délivré au début d'une tranche de temps distincte. La pression d'équilibre est mesurée à la fin de chaque tranche de temps, et une somme des échantillons de pression est générée à partir des signaux de pression. Pour des débits forts, la pompe est commandée de façon à faire varier le débit, et la modification de la pression est divisée par la modification de l'écoulement, ce qui permet de calculer directement la résistance. Un dispositif d'affichage de la résistance affiche en continu la résistance du système. Le codage et le décodage pseudo-aléatoires peuvent être utilisés pour éliminer par filtration la diaphonie de la réponse en pression due aux multiples segments de perfusion aboutissant à un même tuyau.

Abstract: Enhanced inserts are formed having a cylindrical grip and a protrusion extending from the grip. An ultra hard material layer is bonded on top of the protrusion. The inserts are mounted on a rock bit and contact the earth formations off center. The ultra hard material layer is thickest at a critical zone which encompasses a major portion of the region of contact between the insert and the earth formation. Transition layers may also be formed between the ultra hard material layer and the protrusion so as to reduce the residual stresses formed on the interface between the ultra hard material and the protrusion.

Abstract: The compressor contains at least one piston which, together with a cylinder insert, bounds a ring gap which is open over the common longitudinal section and permits a leakage flow of the compressed medium. The piston rod co-operates with a piston and a support part via support surfaces which permit relative movements of the support part with respect to the piston which extend transversely to the longitudinal axis. The piston has a metallic basic body and a sleeve member made of a plastic material on which the running surface of the piston is formed. The cylinder is manufactured of a material whose coefficient of thermal expansion corresponds at least approximately to a resultant coefficient of thermal expansion of the materials of the basic body and of the sleeve member. The compressor in accordance with the invention is particularly suitable for the oil-free compression of a gas.

Title: Virtual address access to tiled surfaces
Inventor: SWANSON ROGER W
IPC: G09G5/393
Filed: 1998-06-18
Granted: 2007-09-04
Abstract: A data accessing system (160) provides access data to video display stored i n one or more frame buffers (45) via a virtual frame buffer implemented as phantom port (201). The virtual frame buffer facilitates remapping between pixel coordinate space and memory address space for both tiled and linear addressing schemes. Generation of virtual linear and virtual tiled addresses is obtained through one or more of shifting, replacing, and concatenating operations. These operations can be implemented to perform very fast in comparison to the multiplication, addition, division, and modulo operations used in convential display processors, video controllers and central processing units (80). In some embodiments the virtual addresses are convert ed to addresses in a frame buffer for accessing the frame buffer. Alternate embodiments use a frame buffer adapted to respond directly to generated virtual addresses. The present invention can thus generate addresses for accessing data in a frame buffer and efficiently use data storage capacity i n the frame buffer.
