Inventor: YANG OLIVER
IPC: H04L12/56
Filed: 2003-09-23
Abstract: An adaptive predictive playout scheme, based on a Least Mean Square (LMS) prediction algorithm, for packet voice applications. The packets are received and stored in a buffer for playout at a constant draining rate P0, where P0 is determined by the codec used. The latency of the packets in the buffer is controlled by discarding the oldest packet in the buffer when the predicted time interval for receipt of the next incoming packet is less than a draining threshold.

Filed: 2002-05-24
Abstract: The entire area of transmission range of information such as shape vector da ta and event information is divided into a plurality of hierarchies of division s and division definition is performed so that data amounts in respective divisions are almost identical. A transmission sides creates and transmits shape vector data, event information, shape vector index data including the division definition and reference data indicating correspondence between divisions, and a list of shape vectors indicating shape vector data containe d in the divisions. A reception side calculates a division necessary for processing based on the shape vector index data and the list of the shape vectors, extracts shape vector data contained in the division, and performs shape matching of the extracted shape vector data, thereby specifying a segment on the digital map and a position in the segment to which the event information corresponds. Thus, when transmitting and displaying shape information such as roads expressing map information and related information to the shape information such as snarl-up and an accident, it is possible to efficiently extract and display information of a necessary range.

Abstract: A passive touch system includes a touch surface and at least one source of backlight illumination projecting backlighting across the touch surface. At least two image sensors are associated with the touch surface and acquire images of the touch surface from different locations. A digital signal processor is associated with each image sensor. The digital signal processors select pixel subsets of images acquired by the image sensors and process pixel data acquired by the selected pixel subsets to generate pointer characteristic data when a pointer exists in the acquired images. A master digital signal processor in communication with the digital signal processors triangulates the pointer characteristic data to determine the location of the pointer relative to the touch surface.

Inventor: WU MIANXUE
IPC: B24D18/00
Filed: 1998-09-25
Abstract: A method of obtaining superabrasive grinding performance from tools employing less expensive, non-superabrasive conventional abrasive grain involves operating the conventional abrasive tool at ultra high tangential contact speed, (that is at least about 125 m/s). Such ultra high operating speeds can be achieved with segmented abrasive grinding wheels having segments formed from vitreous or resin bonded particles of aluminum oxide, silicon oxide, iron oxide, molybdenum oxide, vanadium oxide; tungsten carbide, silicon carbide and the like. The abrasive segments can be cemented to the core of the tool with an adhesive such as epoxy cement. Abrasive segments can be made to a significantly greater depth than traditional superabrasive-bearing segments, and consequently, should provide long life as well as high performance Additionally, conventional abrasive segments are easier to true and dress and to make into intricate profiles for grinding complex shaped work pieces.

Abstract: L'invention concerne un procédé de détermination de la granulométrie (PSD) d'agents de pontage dans des fluides, en particulier de fluides aqueux utilisés dans la récupération d'hydrocarbures, tels que des boues de forage, des fluides de complétion, et similaires. On a mis en évidence que la granulométrie peut être déterminée de façon sélective pour le carbonate de calcium sous forme d'agent de pontage par son auto-fluorescence. Ledit procédé est reproductible sans être affecté par la présence d'autres particules telles que des solides de forage qui font obstacle aux procédés classiques, par exemple, des techniques de diffusion de la lumière. La lumière utilisée pour rendre fluorescent l'agent de pontage peut être filtrée à une fréquence particulière si d'autres composants présents deviennent fluorescents. La cytométrie de flux est une autre technique s'utilisant pour mettre en oeuvre l'objet de l'invention.

Patent CA-2472325-A1 (CA)
Inventor: MOLLER JENS KLOPPENBORG
IPC: C12M1/12
Filed: 2002-12-03
Abstract: A process for ultrafiltration using a spiral wound membrane filter is disclosed where the pressure in the space between the filter element and the pressure vessel is higher than or equal to the pressure inside the filter element. Using these conditions the static force created by the pressure provides a high friction between different sheets in the spiral wound filter element, which efficient prevents unwinding or telescoping of the filter element. Using this configuration it is possible to perform the ultrafiltration using a higher differential pressure across the filter eleme nt than would otherwise have been possible which leads to a higher efficiency a nd a low energy consumption. Further an anti telescoping device (ATD) and a spiral wound filter element, which are particular suited for the disclosed process, are described.
