Patent CA-2346141-A1 (CA)
Title: Single sensor concealed conductor locator
Inventor: MILLER LAWRENCE F
IPC: G01B7/00
Filed: 2000-08-02
Abstract: A single-sensor measurement system for detection and location of an AC signa l emanating from a concealed energized electric conductor. A calibration routi ne of a measurement process carried out by the instrument first determines the background signal level of the AC signal at an initial position of the instrument. A second AC signal level is measured at a second location. The second signal level is compared with the background signal level. A signal indicating the presence of the energized electric conductor is generated by the instrument when the comparison result is greater than or equal to a predetermined value. The instrument initially positioned directly over a concealed energized electric conductor is automatically re-calibrated when a  decrease in the AC signal level of a predetermined amount is detected. The electric field sensor is directly printed on the inside bottom panel of the instrument case and over the raised portions formed on the inside bottom panel. Electrical contact is made between the electric field sensor and the associated circuitry on a PCB in the case when the instrument is assembled.< /SDOAB>
Patent CA-2346416-A1 (CA)
Inventor: DENNEN MICHAEL W
IPC: H01L29/78
Filed: 1999-11-04
Abstract: An offset drain Fermi-threshold field effect transistor (Fermi-FET) includes spaced apart source and drain regions in an integrated circuit substrate, and a Fermi-FET channel in the integrated circuit substrate, between the spaced apart source and drain regions. A gate insulating layer is on the integrated circuit substrate between the spaced apart source and drain regions, and a gate electrode is on the gate insulating layer. The gate electrode is closer to the source region than to the drain region. Stated differently, the drain region is spaced farther away from the gate electrode than the source region.  The offset drain Fermi-FET can introduce a drift region between the drain region and the Fermi-FET channel that can provide the high voltage and/or high frequency Fermi-FETs, while retaining the Fermi-FET advantages in the channel.

Title: Viral detection method using viral encoded enzymes and chemiluminescent substrates
Inventor: SHIMASAKI CRAIG D
IPC: G01N33/58
Filed: 2000-04-12
Abstract: A chemiluminescent system for detecting the presence of influenza virus in a biological fluid sample is provided. An influenza diagnostic kit is provided which includes (1) a sampling device for obtaining the biological fluid from a subject, (2) a chemiluminescent substrate material which, in the presence of influenza virus in the biological sample, will generate a chemiluminescent product that will produce detectable light, and (3) a means for detecting any generated light. A liquid sample containing the biological fluid, and preferably a diluent, are contacted with an absorbent material containing the chemiluminescent substrate material. The substrate responds to neuraminidase activity intrinsic to influenza A and influenza B virus particles, such that when the substrate is in contact with influenza virus, the substrate is cleaved to yield a chemiluminescent product that then decomposes to produce light which can then be detected. The chemiluminescent substrate materials include enzymatically triggerable 1,2-dioxetane derivatives of 4-alkoxy-N-acetylneuraminic acid and 4,7-dialkoxy-N-acetylneuraminic acid. The system is sufficiently simple that it can reliably be used by a layperson in a nonmedical setting. The biological fluid generally originates from the oral cavity, the pharyngeal cavity, or the nasopharyngeal cavity.

Patent CA-2371964-A1 (CA)
Inventor: LAYNE RICHARD
IPC: A61F2/07
Filed: 2000-02-02
Abstract: Partially encapsulated stents are made using gaps cut into ePTFE covering material. Ring stents are placed over an inner ePTFE tube (e.g., supported o n a mandrel) and are covered by a "lacey" graft sleeve, which is constructed b y cutting apertures into an ePTFE tube so that a series of circumferential and  longitudinal strips is created. This "lacey" sleeve is then laminated to the  inner ePTFE tube to capture the stents. By selecting the size and position o f the apertures in the ePTFE covering, it is possible to leave critical parts of the stent unencapsulated to facilitate flexibility and expansion. Alternatively, the gaps can consist of slits cut into the ePTFE covering material. These slits can be cut in any direction including longitudinally, radially, or diagonally. In addition, the slits can be spaced at varying intervals around the covering material to maximize flexibility and expandability. Although a single stent can be used, these approaches lend themselves to use of a plurality of individual ring stents spaced apart alon g the inner ePTFE tube.

Title: Sealant-containing tire
Inventor: YAMAGIWA TOSHIO
IPC: B60C1/00
Filed: 2000-04-18
Abstract: In a sealant-containing tire, an outer liner is fastened to an inner surface of a tread of a tire body, and a sealant chamber that is filled with sealant is defined between a central part of an inner liner and an inner surface of an outer liner by fastening left and right ends of an inner liner to an inner surface of a side wall of a tire body. The tire body comprises a mixture of butyl rubber and natural rubber, or a mixture of butyl rubber and acrylonitrile butadiene rubber, the outer liner comprises natural rubber, and the inner liner comprises butyl rubber. The sealant chamber can therefore be reliably formed without the outer liner and the inner liner becoming fastened together during vulcanization molding without employing an anti-sticking agent or an anti-sticking sheet.
Patent CA-2373523-A1 (CA)
Title: Intelligent splitter, system, and methods of use
Inventor: MOKRYN MAREK
IPC: G06F13/40
Filed: 2000-06-28
Abstract: An intelligent I/O stream splitter is disclosed that may intercept and alter an I/O stream received by the splitter from a communications link. For example, in the case of mirroring, the intelligent splitter may intercept write commands and associated data from a mainframe that target a specific storage location on a specific control unit. The splitter may then transmit the intercepted I/O stream to the targeted control unit and storage location over one link and in parallel transmit on another link an altered version of the intercepted I/O stream to another control unit, which is responsible for holding a mirrored version of the data. The altered version could have the same data as that on the one link but have new frame headers injected at appropriate points in the I/O stream. Moreover, the intelligent splitter may improve the functionality of extended functions such as mirroring as well.

Patent CA-2384214-A1 (CA)
Title: Oil well tubing injection system
Inventor: GIPSON TOMMIE C
IPC: E21B19/22
Filed: 2002-04-29
Abstract: The injector of the invention provides a means and method for injecting either coiled tubing or conventional stalked tubing into and from a well by developing axial forces in the tubing. The curvature of the coiled tubing is simultaneously selectably alters on the opposite side of the injector from the wellhead. To develop traction on the tubing, the injector relies upon an array of opposed pairs of annularly grooved driven rollers which are urged into contact with the tubing. The pairs of rollers are mounted in an alternating pattern 90° apart so that the tubing is well supported and urged into roundness. Integral with the injector, but deactivated when the injector is used with stalked tubing, is a selectably operable tubing straightener which serves to straighten the tubing before entry into the well and also to recurve the tubing being withdrawn from the well to control its arcuate path between the injector and the tubing storage reel. Additionally, the injector unit has an integral slip unit for gripping the tubing in cases when it is desirable to support the tubing axially without operating the tractive portion of the injector.
