Patent CA-2258898-A1 (CA)
Title: Microchip drug delivery devices
Inventor: GOPFERICH ACHIM M
IPC: A61K9/52
Filed: 1997-07-02
Abstract: Microchips are provided, which control both the rate and time of release of multiple chemical substances and which allow for the release of a wide variety of molecules in either a continuous or pulsatile manner. In all of the preferred embodiments, a material that is impermeable to the drugs or other molecules to be delivered and the surrounding fluids is used as the substrate. Reservoirs are etched into the substrate using either chemical (wet) etching or ion beam (dry) etching techniques well-known in the field of microfabrication. Hundreds to thousands of reservoirs can be fabricated on a single microchip using these techniques. A release system, which includes the molecules to be delivered, is inserted into the reservoirs by injection, inkjet printing or spin coating methods. Exemplary release systems include polymers and polymeric matrices, non-polymeric matrices, and other excipients or diluents. The physical properties of the release system control the rate of release of the molecules. The reservoirs can contain multiple drugs or other molecules in variable dosages. The filled reservoirs can be capped with materials that either degrade, dissolve, or allow the molecules to diffuse passively out of the reservoir over time or materials that, upon application of an electric potential, oxidize to form soluble compounds or ions that dissolve into the surrounding fluids. Release from an active device can be controlled by a preprogrammed microprocessor, remote control, or by biosensors.

Inventor: WALLER PETER
IPC: G09B9/32
Filed: 1999-06-16
Abstract: A simulator system in which a visual display assembly is arranged to present an image to be viewed on a display surface and a viewing station is positioned in front of the display surface such that a person looking from a predetermined eyepoint defined within the viewing station can see the display surface through a viewing window defined by the viewing station. The viewing station is displaceable relative to the visual display assembly between first and second positions to adjust the position of the display surface relative to the viewing window when viewed from the eyepoint. Dining displacement of the viewing station between the two positions, the viewing station is rotated about the eyepoint. The actuator is arranged such that the rate of rotation of the viewing station increases with distance from the first and second positions to a maximum when the viewing station is in an intermediate position.

Patent CA-2280083-A1 (CA)
Title: Gas filter separator/coalescer and multi-stage vessel
Inventor: VON PHUL STEPHEN A
IPC: B01D50/00
Filed: 1998-02-02
Abstract: The present invention relates to an apparatus for separating liquids and solids from a gas stream and simultaneously coalescing liquids from the gas stream.  The apparatus includes a closed vessel having a longitudinally extending length, an initially open interior, an input port at an extent and an output port at an opposite extent thereof. There is a partition located within the vessel interior that divides the vessel interior into a first stage and a second stage. There is at least one opening in the partition. A separator/coalescer filter element is disposed within the vessel to sealingly extend from within the first stage through the opening into the second stage. There is a chevron-type seal or an O-ring seal between the filter element and the opening. The input port, vessel interior, separator/coalescer filter element and output port together define a flow passage within the apparatus, whereby the gas stream flows into the first stage through the input port and through the filter element hollow core, thereby filtering solids out of the gas stream, separating liquids from the gas stream, and pre-coalescing liquids in the gas stream. The gas stream then flows along the hollow core past the partition and back through the filter element into the second stage, thereby coalescing liquids out of the gas stream, the gas stream then exiting the second stage through the outlet port.

Inventor: KOSCHITZKY HENRY
IPC: E04D1/26
Filed: 1999-09-28
Abstract: A method of making multiple laminated shingles from a single sheet of roofing material. When four shingles are to be made, the sheet is cut into five strips, namely first and second double shims, first and second single tooth strips, and a double tooth strip. Each double shim is then laminated below the tooth portion of a single tooth strip and the tooth portion at one side of a double tooth strip, to produce a single lamination strip. The lamination strip is then slit lengthwise and crosscut by a single conventional shingle cutter to produce four lanes of shingles across the width of the lamination strip. The process can produce other numbers of shingle lanes. In all cases, the various strips needed are, after being cut, re-assembled into a single lamination strip so that they can be slit and crosscut by a single standard shingle cutter.

Title: A method and a system for determination of particles in a liquid sample
Inventor: ARNVIDARSON BOERKUR
IPC: G01N15/02
Filed: 1998-05-05
Abstract: The present invention relates to a method for the assessment of quantity and quality parameters of biological particles in a liquid analyte material. The method comprises applying a volume of a liquid sample to an exposing domain from which exposing domain electromagnetic signals from the sample in the domain can pass to the exterior, and exposing, onto an array of active detection elements such as CCD-elements, a spatial representation of electromagnetic signals having passed from the domain, the representation being detectable as an intensity by individual active detection elements, under conditions permitting processing of the intensities detected by the array of detection elements during the exposure in such a manner that representations of electromagnetic signals from the biological particles are identified as distinct from representations of electromagnetic signals from background signals. The size of the volume of the liquid sample is sufficiently large to permit the assessment of the quantity and quality parameters to fullfil a predetermined requirement to the statistical quality of the assessment based on substantially one exposure.
