Patent CA-2774597-A1 (CA)
Inventor: BYRNS PATRIC
IPC: B60S5/00
Filed: 2012-04-19
Abstract: L'invention vise à fournir un ensemble de groupes de composantes modulaires pour les véhicules, comme les véhicules de service électriques, et permettre une réparation rapide et directe sur place. Les composantes de véhicule sont disposées à l'intérieur des modules groupés, les modules étant reliés de manière amovible et fonctionnelle au véhicule et adaptés pour fournir facilement un diagnostic des pannes de composante. Les modules groupés sont conçus pour être échangés de manière indépendante en cas de panne d'une simple composante d'un groupe, sans nécessiter que la réparation soit faite sur place. Le retrait et le remplacement d'un module du groupe exigent des compétences minimales en mécanique et le module défaillant peut alors être envoyé à l'atelier pour réparation. Le système permet un entretien simplifié des véhicules lorsqu'il serait difficile de déplacer le véhicule entier vers un lieu d'entretien.

Title: Systems and methods for phase predictive impedance loss model calibration and compensation
Inventor: HECKEL DONALD W
IPC: A61B18/00
Filed: 2012-12-18
Abstract: The systems and methods of the present disclosure calibrate impedance loss model parameters associated with an electrosurgical system having no external cabling or having external cabling with a fixed or known reactance, and obtain accurate electrical measurements of a tissue site by compensating for impedance losses associated with the transmission line of an electrosurgical device using the calibrated impedance loss model parameters. A computer system stores voltage and current sensor data for a range of different test loads and calculates sensed impedance values for each test load. The computer system then predicts a phase value for each load using each respective load impedance value.  The computer system back calculates impedance loss model parameters including a source impedance parameter and a leakage impedance parameter based upon the voltage and current sensor data, the predicted phase values, and the impedance values of the test loads. During operation, the electrosurgical device senses a voltage and a current, predicts a phase value based upon the sensed voltage and current, and calculates metrics at the tissue site based upon the sensed voltage and current, the predicted phase value, the source impedance parameter, and the leakage impedance parameter.

IPC: H04W16/14
Filed: 2011-03-30
Abstract: Method, apparatus, and computer program product embodiments are disclosed for independent wireless resource sharing on a fair basis to enable selecting the most suitable coexistence between wireless networks. Example embodiments of the invention include a hierarchical resource request process that enables reallocation of radio resources in a coexistence band. When new resources are requested by a network, a search is made for free resources in the coexistence band. If this does not succeed, a check is made for any allocated but unused resources in the coexistence band that have been advertised by neighboring networks. If there are insufficient advertised resources, then the allocation of resources in neighboring networks is analyzed and compared with the requesting network's need for network resources. There are two graduated stages to the analysis. In an example light analysis stage, an analysis of the allocation of resources is limited to neighboring networks within the same network allocation group as the requesting network's. In a more extensive analysis stage, all of the neighboring networks are analyzed. In this manner, a more complete resource reallocation may be achieved.

Filed: 2013-03-27
Abstract: A method is provided for a streaming hierarchy traversal renderer with particular application for feature films and other demanding content creation using scenes of high complexity that cannot fit in memory. The renderer organizes scene geometry into a spatial hierarchy, generates directional queries to be traced in the spatial hierarchy, performs a streaming hierarchy traversal over the directional queries, and uses the results of the directional queries to shade or render the scene. The traversal performs a single pass over the directional queries for splitting into one child stream of directional queries for each child node at each scene node in the hierarchy. A prioritized traversal of the hierarchy may also be carried out using various cost-metrics for optimized parallelism. The rendering may also bounce the directional queries to provide multi-pass global illumination.

Abstract: A radio-frequency identification (RFID) reader having fast-adaptive echo cancellation for backscatter-modulated signals is described. The echo cancellation includes subtracting an RF-level cancel signal from the received signal, where the cancel signal is generated based upon an error measured in the receive signal after down-conversion to baseband and low-pass filtering.
