Title: Presentation system for individual personal computers in a personal computer network
Inventor: KJORSVIK REIDAR
IPC: G06F17/30
Filed: 1996-09-02
Abstract: The network presentation system includes a database on a network server, the database being administered and controlled by an administration software module. The administration module creates individual images from text and/or visual material and then organizes a series of such images into a presentation which is stored in the database. The presentation is displayed on the screens of the individual PCs in the network by the action of a messenger software module present in each PC, following passage of a selected amount of time during which the PC is on but is not used. The messenger module maintains control over the presentation of the images in the particular presentation sequence following interruptions of actual use by the PC. A PC user has the capability of returning the PC to its conventional use, but also has the capability of controlling the presentation to an extent, or even changing to an entirely different presentation among the several which may be available to that specific user.

Title: Oxygen mixing in a blower-based ventilator
Inventor: SROCK JAMES D
IPC: A61M16/12
Filed: 1997-08-21
Abstract: This invention is an oxygen mixing arrangement for, or in a pressure support ventilator in which a modular oxygen-providing assembly is selectively inserted into a greater respiration apparatus (200). Mixing accuracy and controllability is maintained by using gas supplies that have a wide range of pressures. Further, oxygen leakage is minimized by connecting the modular oxygen-providing assembly at a point of the respiration circuit of the greater respiration apparatus (200) that is downstream from a valving arrangement normally used for venting patient exhaust flow and for controlling system pressure by venting excess gas flow to the ambient atmosphere.

Patent CA-2244349-A1 (CA)
Inventor: PELLETIER JOELLE NINA
IPC: G01N33/58
Filed: 1998-07-30
Abstract: We describe a strategy for designing and implementing protein-fragment complementation assays (PCAs) to detect biomolecular interactions in vivo and in vitro. A Protein Complementation Assay/Universal Reporter System (PCA/URS) for detecting and screening for agonists and antagonists of a membrane receptor is also described. The design, implementation and broad applications of this strategy are illustrated with a large number of enzymes with particular detail provided for the example of murine dihydrofolate reductase (DHFR). Fusion peptides consisting of N- and C-terminal fragments of murine DHFR fused to GCN4 leucine zipper sequences were coexpressed in Escherichia coli grown in minimal medium, where the endogenous DHFR  activity was inhibited with trimethoprim. Coexpression of the complementary fusion products restored colony formation. Survival only occurred when both DHFR fragments were present and contained leucine-zipper forming sequences, demonstrating that reconstitution of enzyme activity requires assistance of leucine zipper formation. DHFR fragment-interface point mutants of increasing severity (Ile to Val, Ala and Gly) resulted in a sequential increase in E. coli doubling times illustrating the successful DHFR fragment reassembly rather than non-specific interactions between fragments.  This assay could be used to study equilibrium and kinetic aspects of molecular interactions including protein-protein, protein-DNA, protein-RNA, protein-carbohydrate and protein-small molecule interactions, for screening cDNA libraries for binding of a target protein with unknown proteins or libraries of small organic molecules for biological activity. The selection and design criteria applied here is developed for numerous examples of clonal selection, colorometric, fluorometric and other assays based on enzymes whose products can be measured. The development of such assay systems is shown to be simple, and provides for a diverse set of protein fragment complementation applications.
Patent CA-2244521-A1 (CA)
Inventor: WHEELER THOMAS J
IPC: F04B49/12
Filed: 1998-07-29
Abstract: An inflator mechanism has a valve adapted to secure with the device to be inflated. A compressor is fluidly coupled with the valve mechanism. The compressor mechanism generates fluid to inflate the device. The compressor mechanism includes a motor to drive a piston, a piston, a piston cylinder, an outlet coupled between the piston cylinder and the valve, and a housing. A biasing spring is positioned in the housing to exert a force on the cylinder. The biasing force maintains the cylinder in a first position when the fluid in the cylinder is at a low pressure. The cylinder moves in the housing against the force of the biasing spring to a second position when the fluid in the cylinder is at a high pressure. A displacement control valve is associated with the cylinder to control the fluid displacement of the compressor. Thus, at low pressure, fluid displacement is high and as pressure in the cylinder increases, the fluid displacement is reduced. A power source is coupled to drive the motor of the compressor.
