Patent CA-2311059-A1 (CA)
Inventor: PIERSON MARK W
IPC: C12Q1/06
Filed: 1998-10-27
Abstract: Method and assay devices for the detection of the presence or amount of biological material, analyte(s), or microorganism(s) in a sample. The method includes the steps of liquefying the sample (if necessary) and distributing the liquefied sample over the surface of the assay device. The device may comprise an incubation plate, a dip stick device, or other devices. The devices have at least one reagent provided within the devices. Some devices have a generally flat horizontal surface which is divided into a plurality of recessed wells. Others have one or more surfaces with reagent island(s) immobilized thereon.  Each well or reagent island is adapted to hold an aliquot of liquid. The wells or reagent islands are sized and shaped, and formed of a suitable material, to hold the aliquot within the well or reagent island by surface tension. Any excess liquid from the liquefied sample is drained from the surface of the device. The method then involves incubating the assay device until the presence or amount of the biological material, analyze, or microorganism is determined.

Title: Method and system for predicting transactions
Inventor: FREEMAN CLIVE
IPC: G06F17/30
Filed: 2000-06-13
Abstract: The invention provides a system for predicting a transaction a customer may wish to make. In, for example, an Internet banking system, when the customer clicks to bring up an "inter-account transfer" panel, the system may recognise that usually, with a given balance in their savings and cheque accounts, and at this time of the month, at this point in the financial year, the customer will want to transfer a given amount to their cheque account. So, as well as providing a window enabling the customer to manually enter the details for an inter-account transfer, the system also provides a personalised window containing the system's anticipated transaction so that with a single-click the customer can complete the transaction.

Abstract: A switchgear assembly in which a number of cells housing electrical switching apparatus such as circuit breakers are vertically stacked in a forward compartment has combined arc shield/wire trays between cells for terminating secondary wiring for easy access through front doors on the switchgear assembly and for protecting the secondary wiring from circuit breaker arc gases. The arc gases are deflected by an upwardly and rearwardly inclined panel forming the back wall of the wire tray. A vertical wall forward of the inclined panel mounts a lower horizontal row of terminal blocks forward of an upper row. A wireway has a vertical section in a forward corner of the cabinet beside the vertically stacked cells which communicates with the wire trays, and a horizontal section extending rearward under the top wall of the cabinet. An inclined gutter provides a transition between the top of the vertical section and the forward end of the horizontal section. External wiring enters the wireway either through a bottom access opening aligned with the vertical section or a top access opening in the horizontal section. A depending lip on the rear of the arc shield diverts the arc gases laterally into a vertical chamber behind the vertical section of the wireway for expansion and cooling.

IPC: A61K51/08

Abstract: The labeling of biologically important molecules via a bifunctional chelator can result in the formation of isomers or multiple species, which can have significant impact on the biological properties of the radiopharmaceutical.  For receptor-based radiopharmaceuticals, the target uptake is largely dependent on the receptor binding affinity of the targeting molecule and the blood clearance of the labeled molecule, which is determined by the physical properties of both the targeting molecule and the metal chelate. Hence, the presence of isomers for the metal chelate can have significant impact on the radiopharmaceutical. Therefore, in the development of a radiopharmaceutical or metallodrug, it is necessary to separate the isomers and evaluate the biological activities of each individual isomer. It would therefore be desirable to develop chelators that predominately form only a single stereoisomeric species upon coordination to a metal center. Disclosed herein are chelators that form a mixture enriched for a single stereoisomeric species upon coordination to a metal center.

IPC: H01L21/20
Filed: 1999-04-09
Abstract: A SiGe monocrystalline etch-stop material system on a monocrystalline silico n substrate. The etch-stop material system can vary in exact composition, but is a doped or undoped Si1-xGex alloy with x generally between 0.2 and 0.5. The etch-stop of the invention includes the use of a graded-composition buffer between the silicon substrate and the uniform SiGe etch-stop mateial. Nominally, the buffer has a linearly-changing composition with respect to thickness, from pure silicon at the substrate/buffer interface to a composition of germanium, and dopant if also present, at the buffer/etch-sto p interface which can still be etched at an appreciable rate. Here, there is a  strategic jump in germanium and concentration from the buffer side of the interface to the etch-stop material, such that the etch-stop layer is considerably more resistant to the etchant. The etch-stop is used for micromachining by aqueous anisotropic etchants of silicon such as potassium hydroxide, sodium hydroxide, litium hydroxide, ethylenediamine/pyrocatechol/pyrazine (EDP), TMAH, and hydrazine.
