Patent CA-2315872-A1 (CA)
Inventor: RISKIN YEFIM
IPC: H01T19/04
Filed: 1997-11-10
Abstract: A method of high efficiency generation of ions of desired polarity which includes the steps of positioning a first electrode (5) at a predetermined spacing from a second electrode (7) having a closed shape configuration, applying to both electrodes a direct voltage of the same polarity, at the same time as applying the direct voltage, applying high voltage pulses to the first electrode only, thereby to cause ion generation in the vicinity of the first electrode and to set up a rapidly moving ion stream from the first to the second electrode along an electrical field therebetween, wherein the duration of the pulses is shorter than the time taken for the ion stream to reach the second electrode, and wherein ions in the ion stream have the same polarity as the second electrode, thereby to be repelled and concentrated as they flow through the second electrode. The method may also include the generation of a stream of ions, with reduced ozone content, which includes the additional step of applying a negative pressure gradient to the ion stream, thereby to deflect ozone generated by the corona discharge to a direction different from that of the flow of ions.

Patent CA-2320230-A1 (CA)
Inventor: COSMAN ERIC R
IPC: A61B19/00
Filed: 1998-12-01
Abstract: A system for positioning and repositioning of a portion of a patient's body with respect to a treatment or imaging machine includes multiple cameras to view the body and the machine. Index markers, either light-emitting, passive, geometric shapes, or natural landmarks, are identified and located by the cameras in 3D space. In one embodiment, such reference or index markers are in a determinable relationship to analogous markers used during previous image scanning of the patient. Anatomical targets determined from image scanning can be located relative to reference positions associated with the treatment or diagnostic machine. Several forms of camera, index markers, methods and systems accommodate different clinical uses. X-ray imaging of the patient further refines anatomical target positioning relative to the treatment or diagnostic imaging reference point. Movements of the patient based on comparative analysis of imaging determined anatomical targets relativeto reference points on treatment or diagnostic apparatus are controlled by the system and process of the invention.

According to the invention, antigens are targeted to dendritic cells by apoptotic cells which may also be modified to express non-native antigens for presentation to the dendritic cells. The dendritic cells which are primed by the apoptotic cells are capable of processing and presenting the processed antigen and inducing cytotoxic T lymphocyte activity or may also be used in vaccine therapies.
Patent CA-2322071-A1 (CA)
Title: Improved trim operation based on enhanced face definition
Inventor: DREYFUS JEAN-PIERRE
IPC: G06T19/20
Filed: 2000-10-03
Abstract: A method, apparatus and system for use in CAD/CAM design in which two or more bodies may be combined to form an assembly. When the assembly is formed, the two bodies intersect so that the volume of the assembly consists of cells containing volume common to both bodies, cells containing volume originating solely from one of the bodies, and cells containing volume originating solely from the other body. Often it is desirable to remove a portion of the assembly consisting of a cell originating solely from one of the bodies. In an existing system this can be done by selecting a face of such a cell, provided however, that said face has not been created by dividing one of the faces of the original bodies. If a divided face is selected, additional user inputs are required before the removal is executed. According to the present invention, divided faces can be selected directly by the user, without the need for further processing. The preset invention makes use of topology logs to keep track of all faces in the assembly. This alleviates the necessity for extra user input when a divided face is selected.

Filed: 2000-12-04
Abstract: Packet processing logic includes a request queue for receiving lookup requests from a packet processor, where each request includes information elements from a received packet and indicates that a route lookup and a packet classification are to be performed based on the information elements. Both a route lookup engine (RLE) and a packet classification engine (PCE) have respective inputs coupled to the request queue for receiving selected information elements from the requests. Based on the information elements in each request, the RLE searches for forwarding information indicating how the packet corresponding to the request should be forwarded, and the PCE performs a classification process and generates classification information about the packet corresponding to the request. For each request, the forwarding information from the RLE and the classification information from the PCE are combined into a single result stored in a result queue. Each result is provided to the packet processor in a single communication transaction therewith.

Title: Method for removal of atm cells from an atm communications device
Inventor: THUDT RAIMAR
IPC: H04L12/54
Filed: 1999-02-26
Abstract: A number of algorithms have been used in prior art for dealing with overload situations in ATM transmission systems. The PPD and LPD algorithms are examples of known methods. When the PPD method is used, the dynamic load to which the ATM network is subjected is still too great since not all of the ATM cells can be rejected. Those ATM  cells which do not belong to a frame also pose a problem in the rejection process. The invention solves this problem by establishing rules which when applied, ensure that the PPD method is only used within very strict limits and that those ATM cells not belonging to a frame are not rejected.

Abstract: A multilayered microfluidic device having a substantially monolithic structu re is formed by sintering together a plurality of green-sheet layers. The substantially monolithic structure has an inlet port for receiving fluid, an  outlet port for releasing fluid, and an interconnection between the inlet po rt and the outlet port. The substantially monolithic structure may also include  a variety of components to enable useful interaction with the fluid, such as electrically conductive pathways, heaters, fluid sensors, fluid motion transducers, and optically transmissive portions.
