Patent CA-2467050-A1 (CA)
Inventor: BIBETTE JEROME
IPC: C12Q1/68
Filed: 2002-11-20
Abstract: The invention concerns a method for detecting and/or quantifying at least an analyte in a liquid medium, characterized in that it consists in using magnetic colloidal particles functionalized at the surface with at least a ligand specific of the analyte to be detected and/or assayed and in that it comprises: contacting said particles with said medium to be analyzed; applying a magnetic field to said medium, at an intensity sufficient to cause said magnetic particles to be structured in the form of chains; maintaining said magnetic field for a sufficient time interval to enable coupling or combination of the analyte concerned with at least two specific ligands present respectively on two neighbouring particles of a chain; cancelling the magnetic field, and determining the presence and/or absence of said analyte and, as the case may be, its concentration via the presence and/or the absence of said permanent chains of magnetic particles.

Title: Surgical stapling instrument incorporating an e-beam firing mechanism
Inventor: SHELTON FREDERICK E IV
IPC: A61B17/072
Filed: 2004-05-20
Abstract: A surgical severing and stapling instrument clamps, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel clot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing.

Title: Electromagnetic surveying for hydrocarbon reservoirs
Inventor: MACGREGOR LUCY M
IPC: G01V3/12
Filed: 2002-11-28
Abstract: An electromagnetic survey method for surveying an area previously identified as potentially containing a subsea hydrocarbon reservoir, comprising obtaining first and second survey data sets with an electromagnetic source aligned end-on and broadside relative to the same or different receivers. The invention also relates to planning a survey using this method, and to analysis of survey data taken in combination allow the galvanic contribution to the signals collected at the receiver to be contrasted with the inductive effects, and the effects of signal attenuation, which are highly dependent on local properties of the rock formation, overlying water and air at the survey area. This is very important to the success of using electromagnetic surveying for identifying hydrocarbon reserves and distinguishing them from other classes of structure.

Abstract: A tine for mounting on a rotatable shaft of soil aeration and cultivation equipment, comprising: mounting means at an attachment end of the tine; a tip at a ground- engaging end of the tine opposite the attachment end; leading and trailing convert curvilinear edges disposed opposite each other and converging toward the attachment end and the tip; and bevelled sections on each of the leading and trailing convex curvilinear edges. The unique shape of the tine has been found to create a wider range of soil disturbance than is the case with conventional straight-edge tines, requires less material to manufacture, and penetrates the ground surface more easily than conventional straightedge tines due to the convex leading edge.

Abstract: A handheld client framework system provides a server proxy client (509) that services client requests for network accessible information and determines the server that is most appropriate to supply the requested information and sends information request packets to that server across the Internet and/or intranet. Server responses to information requests are received by the server proxy client. The server proxy client separates the response information into the appropriate data components. Data components are sent to the appropriate client. Presentation and logic components are temporarily stored in a one-behind cache on the client (501). A client will continue to use the presentation and logic components already installed or in the one-behind cache to service the current user request. Any updates sent by the server proxy client (509) and stored in the one-behind cache are retrieved by the client upon subsequent use by the user.

Title: Safety cartridge for retrievable medical filter
Inventor: MULDER RUDOLF T
IPC: A61F2/06
Filed: 2005-09-29
Abstract: The present invention relates to a safety cartridge for a medical filter which can be inserted through a percutaneous access point, via a catheter or introducer, and placed in a blood vessel or other body passage. Filters may have features which are not longitudinally symmetrical, such as anchors or barbs which angle toward one end, or a retrieval hook at only one end. Depending on the physician's selection of the access point, the filter may be introduced to a desired site for treatment from opposing directions. However, it is desirable to introduce the filter with the desired alignment (inserting the desired end in first) regardless of where the selected access point is, and accordingly regardless of which direction of approach to the desired site. As a result, it is desirable to provide a safety cartridge. Cartridges hold filters in an initial compressed shape during storage and insertion into the patient. A safety cartridge may have labels and/or indicators corresponding to which approach direction is selected, showing which end of the cartridge, and so which end of the filter inside the cartridge, to insert first into a catheter or introducer. A safety cartridge may have uniquely shaped first and second ends, which match insertion port(s) on a catheter or introducer which correspond to the selected approach direction. Accordingly, the safety cartridge assists proper orientation of the filter during delivery and treatment.

Title: Bidirectional communication between control element and electrical devices
Inventor: SLATER JAMES S
IPC: G08B29/12
Filed: 2001-04-06
Abstract: A software driven monitoring system includes a common control element coupled to a plurality of monitoring devices. The devices can indicate to the control element that a predetermined condition has been detected. Where the control element transmits a status inquiry command to the devices, those devices exhibiting the status provide the same indication to the control element as is indicative of the predetermined condition. One indication is a shunt or a short circuit of a medium between the common control element and the devices. An existing system can be upgraded by installing the control element, or upgrading an existing control program. Alternately, the devices can be installed in a system wherein the control element does not issue the status inquiry command. In those installations, the monitoring devices never issue a status reply as the required command is never received.
