Patent CA-2154444-A1 (CA)
Title: Chemical functionalization of surfaces
Inventor: KEANA JOHN F W
IPC: G01N33/543
Filed: 1994-01-21
Abstract: Methods for covalently modifying surfaces of various substrates are disclosed, along with various substrates having surfaces modified by such methods. Candidate surfaces include various polymeric, siliceous, metallic, allotropic forms of carbon, and semiconductor surfaces. The surfaces are exposed to a reagent, having molecules each comprising a nitrenogenic group and a functionalizing group, in the presence of energized charged particles such as electrons and ions, photons, or heat, which transform the nitrenogenic reagent to a nitrene intermediate. The nitrene covalently reacts with any of various chemical groups present on the substrate surface, thereby effecting nitrene addition of the functionalazing groups to the substrate surface. The functionalazing groups can then participate in downstream chemistry whereby any of a large variety of functional groups, including biological molecules, can be covalently bonded to the surface, thereby dramatically altering the chemical behavior of the surface. Such functionalization of the surface can be done in a single reactive step or in multiple reactive steps.

Title: Bus transceiver with binary data transmission mode and ternary control transmission mode
Inventor: OPRESCU FLORIN
IPC: H04L5/14
Filed: 1994-03-11
Abstract: The present invention provides a bus transceiver incorporating a high speed, binary transfer mode for the half-duplex transfer of data signals with a ternary control transfer mode having a full duplex dominant logic transmis-sion scheme for the full duplex trans-fert of control signals. In one em-bodiment of the present invention, the above-noted transfer modes are imple-mented in a bus architecture which in-cludes at least a first communications node coupled to a second communi-cations node via a twisted pair, serial bus. Each node comprises first trans-ceiver and second transceivers having a differential driver for driving on the bus signal states comprising first and second signal states having equal cur-rent amplitudes opposite in sign and a third signal state having approximately a zero current amplitude, a high speed binary receiver for receiving high speed data signals during data transfer phases and a ternary receiver for receiving control signals during control transfer phases. The ternary receiver comprises two binary receivers for detecting resultant current amplitudes created on the bus during simultaneous driving of control signals by the nodes during the control trans-fer phases and logic means for combining the resultant current amplitudes on the bus with the signal states driven by the local transceiver to output reconstructed control signals representing the control signals driven on the bus by the corresponding transceiver. Furthermore, both transceivers further include a preemptive signaling receiver for the detection of preemptive control messages which act to terminate the data transfer phases upon receipt of the message so that higher priority control transfers may take place.

Patent CA-2162560-A1 (CA)
Title: Windowing system with independent windows for arbitrary resolution for display on multiple devices of arbitrary resolution
Inventor: HOLLAND SHANNON
IPC: G06F3/048
Filed: 1994-05-05
Abstract: A resolution independent windowing system comprises a method for performing windowing operations directly in device space for a graphics system which specifies all drawings in coordinate space. The re-sizing effects of rendering an object in different places on the coordinate grid are absorbed in the window borders, allowing the window contents to be moved without re-drawing them. The window can be moved without re-drawing it even when the resolution of the device the window is displaced in differs from the source resolution of the rendering system. Furthermore, window contents are drawn relative to the coordinate of the top left of the window to provide each window with its own device grid independent of the window position on the device. The present invention includes: a method for displaying a window independent of the resolution of the display device; a method for rendering multiple, overlapping windows of independently arbitrary resolutions, and a method for scrolling a finite coordinate grid independent of resolution of the display device. These methods can be used alone or in combination to greatly enhance the graphic images displayed on a display device.

Patent CA-2172972-A1 (CA)
Inventor: COOLEY DAVID M
IPC: H04B1/16
Filed: 1994-07-21
Abstract: A power-conserving time division multiple access (TDMA) radiotelephone system is disclosed in which a cluster of subscriber stations, remote from a base station, employs a common pool of frequency-agile modems each of which digitally synthesizes, on a time slot-by-time slot basis, the different channel-identifying intermediate needed to support communications between several of the subscriber stations and the base station. Power conservation is facilitated inter alia by controlling the assignment of modems to calls, maintaining unassigned modems in a powered-down state and by controlling the number of calls using the same time slot. Delay in assigning a powered-down modem to a call is eliminated by making available to all modems the highest quality synchronization information obtained by any of the active modems.

Patent CA-2179238-A1 (CA)
Inventor: GIAMMARUTI ROBERT JOSEPH
IPC: F28D15/02
Filed: 1996-06-17
Abstract: A method and apparatus for separately supporting and sealing a heat pipe within a heat exchanger.  For support, the heat pipe with fins thereon passes through a support grid which consists of a series of rings secured or interconnected together.  The fins of the heat pipe rest upon these rings of the support grid thereby supporting this region of the heat pipe.  To seal these heat pipes in order to prevent any gas escape from the heat exchanger, a tubesheet with openings therein is placed over the ends of the heat pipe.   These openings are oversized thus a considerable gap exists between the tubesheet and the heat pipe.          This gap is covered or sealed by use of a cover disk which tightly fits around the heat pipe and spans across this gap before it is removably secured to the tubesheet.   By this fashion, once the cover disk is removed from the tubesheet, it is a relatively easy task to then remove the tubesheet and the heat pipe from the heat exchanger for maintenance or repair purposes.

Patent CA-2183733-A1 (CA)
Inventor: HEIN GARY L
IPC: A61B17/20
Filed: 1995-02-21
Abstract: This invention is a plastic skin testing and vaccinating needle (5) characterized by an end bifurcated into two sharp points (6) spaced sufficiently close so that in use the points (6) will penetrate and form a small hole in the skin when the needle (5) is simultaneously rotated and pressed against the skin.  The spacing also causes liquid to adhere to and between the points (6) when the end is dipped in skin testing or vaccinating liquid.  The cross section of the needle shaft in sufficiently large that the needle (5) can be readily rotated between a user's thumb and index finger.  Rotation is facilitated by altering or roughening the surface of the shaft so as to reduce slippage during rotation.  Preferably, the needle (5) is formed in a mold produced by electro-discharge machining so as to have an etched or matte surface which enhances the adherence of liquid to the bifurcated end.
