Patent CA-2318881-A1 (CA)
Inventor: GARYANTES TINA
IPC: C40B40/06
Filed: 1999-02-03
Abstract: Microtiter-like plates containing virtual wells formed by an arrangement of relatively hydrophilic domains within relatively hydrophobic fields are provided. Assay mixtures are confined to the hydrophilic domains of the virtual wells by the edges of the hydrophobic fields. The use of virtual wells allows one to perform homogeneous and capture and wash high throughput screening assays with assay mixtures having volumes on the order of about 100 nl to 10µl. Virtual wells also provide a means of easily moving fluids, which is particularly useful for simultaneous additions needed for kinetic studies and flash detection and washing. Methods for controlling evaporation during the dispensing of reagents as well as during incubation of high throughput screening utilizing microtiter-like plates containing virtual wells are also provided. The present invention also provides an inexpensive, disposable device for transferring small volumes of an entire array of compounds from a first microtiter-like plate to a second microtiter-like plate, preserving the spatial arrangement of the compounds. Methods of manufacturing and using the device are also provided.

Title: Guide member for a liquid jet to be deflected
Inventor: BACHMANN CHRISTIAN
IPC: B01D3/16
Filed: 2001-02-27
Abstract: The guide member (1) for a liquid jet (30) to be deflected allows a liquid (3) after flowing out of a container (2) to be deflected onto a target (5; 7) which is located below the container. The deflecting takes place by means of a shaped material plate (10; 10a, 10b) which is arranged ahead of an outlet opening (20) of the container and which reshapes and further conducts the jet (30) in such a manner that the liquid is conveyed to the target at a lower end (17) of the shaped material plate. At the location ahead of the outlet opening (20), where the liquid jet (30) is incident onto the shaped material plate (10), a first and a second piece of surface (11 and 12 respectively) of the material plate form a mouth region (13) in which the first piece of surface (11) deflects the liquid (3) transversely with respect to the vertical, whereas the second piece of surface (12) is provided as a catcher for squirts. The first piece of surface merges into a channel (14) in which the liquid is guided downwards. In this the wall of the second piece of surface divides the channel off from the mouth region. In modified form the guide member can also be assembled from a plurality of shaped material plates.

Title: Method and apparatus for acquiring satellite positioning system signals
Inventor: KRASNER NORMAN F
IPC: G01S1/00
Filed: 1999-07-15
Abstract: A method and an appara-tus which acquire satellite posi-tioning system (SPS) signals in an SPS receiver. Information on time of day, approximate re-ceiver location, and satellite po-sitions are used to reduce the time to search and acquire sig-nals from one or more SPS  satellites. In an example of a method of the invention, a first pseudorange to a first SPS  satel-lite is determined, and an ap-proximate location of the SPS  receiver is determined. An es-timated pseudorange for a sec-ond pseudorange to a second SPS satellite is determined from the approximate location and a satellite position of the second SPS satellite. The SPS receiver then searches for SPS signals from the second SPS satellite in a range determined by the esti-mated pseudorange. Typically, this method reduces the search time to initially acquire SPS signals from the second SPS satellite, and the estimated pseudorange is not based on a previously determined pseudorange for said second SPS satellite. In a particular example of the invention, the approximate location is determined from a cell based information source which correlates an identification of each of various wireless cell sites with an approximate location for objects within a cell of a wireless cell based communication system, such as a cellular (or cell based) telephone system. In other examples of the invention, relatively precise time of day information may be used with information indicating satellite positions and information indicating the approximate location to determine an estimated pseudorange for a first SPS satellite to be acquired.

Title: Capacitance-coupled high dielectric constant embedded capacitors
Inventor: TORMEY ELLEN S
IPC: H05K3/46
Filed: 1999-10-01
Abstract: High dielectric constant capacitors are made from a dielectric ink (30, 32, 34) of lead-magnesium-niobate and lead oxide powders with a suitable organic vehicle which can be used to coat one or more glass-based green tapes. Buried capacitors are made by coating an overlying and an underlying green tape with a conductor (36, 38, 40, 42) such as silver. Capacitors can also be made by adjusting the organic vehicle and forming a green tape from the dielectric powders. These dielectric green tapes each can be coated with a conductive layer and stacked, the conductive layers connected in parallel. The resultant multilayer capacitors have a very high dielectric constant, while eliminating the need for very large area capacitors, as compared to single layer capacitors.
