Patent CA-2424041-A1 (CA)
Title: Hydroform structural reinforcement system
Inventor: BRENNECKE ERIC
IPC: B62D29/00
Filed: 2001-09-26
Abstract: A structural reinforcement system (10) for use with hydroform tubes (18) and other closed forms having a purality of members (12) designed to be secured to a closed form, such as an hydroform tube (18) used in automotive applications.  A bonding material (14), such as an epoxy-based reinforcing foam, is disposed on at least a portion of the outer surface of each of the plurality of members. Once the system is attached to the closed form, the foam expands and cures during an automobile assembly operation, bonding the reinforcement system to the hydroform tube and the members. As a result, the reinforcement system provides enhanced load distribution over the vehicle frame without adding excessive weight and further serves to reduce noise and vibrational characteristics of the automotive vehicle.

Title: Parallel off-hook detection for both line-available and phone pick-up detection
Inventor: KRAMER RICHARD ALAN
IPC: H04M1/738
Filed: 1994-03-25
Abstract: A secondary communications device, such as a modem, a facsimile machine, an automatic meter reader or an answering machine, shares a telephone line with a subscriber's telephone and must grant the telephone primary access to the line. The present invention prevents the secondary device from seizing the line when the telephone is already off-hook and will terminate a line seizure by the secondary device if the subscriber picks up the telephone handset during use of the line by the secondary device. An average interval for charging a capacitor to a threshold voltage in response to an on-hook voltage appearing across the telephone line is determined. When the secondary communications device is ready to use the line, circuitry measures an interval for charging the capacitor in response to the current voltage appearing across the telephone line. The secondary communication device seizes the line only if the measured interval does not exceed the average interval by more than a predetermined amount. After seizure by the secondary communication device, a steady-state condition is brought about between the secondary device, the line steady-state impedance, and the central office voltage source. If the line impedance drops from the steady-state value, the circuitry assumes that the subscriber has taken the telephone off-hook and terminates the line seizure by the secondary device.

Title: Dermabrasion device
Inventor: BERNAZ GABRIEL
IPC: A61B17/54
Filed: 2001-12-24
Abstract: Skin dermabrasion device by gently contacting the skin with an abrasive, comprising a handleable housing (10) and driving means for the abrasive. This device is intended in particular for cosmetic treatments of the epidermis called microepidermabrasion. The device comprises a curved abrasive surface (30) held by a support (32) mounted in or on the housing (10, 18) for an oscillatory motion allowing the oscillation of the curved abrasive surface (30) about its axis. A support surface (40) surrounds the abrasive surface (30) on at least two opposing sides leaving a gap to allow the oscillating motion. The device is arranged in such a way as to allow, by the application of the support surface (44) against the skin (50) and around the region of the skin to be treated, the gentle contact of this region of skin with the oscillating abrasive surface. Thus a microabrasion of the epidermis through the oscillation of the curved abrasive surface (30) lightly applied against the skin is achieved, thanks to the support surface (40) that prevents any injury or penetration beyond the epidermis.

Title: Assay for identifying inhibitors of the rna dependent rna polymerase (ns5b) of hcv
Inventor: MCKERCHER GINETTE
IPC: C12N9/10
Filed: 2002-03-06
Abstract: The present invention provides a novel method for the identification of inhibitors of HCV NS5B polymerase that uses an HCV NS5B RNA-dependent RNA  polymerase having a higher Km than the full length native NS5B polymerase to ensure identification of inhibitors of HCV polymerase primer-template binding, including moderately inhibitory compounds. The method includes providing a decreased-affinity HCV NS5B polymerase, an appropriate primer-template, and a plurality of appropriate ribonucleotide triphosphates, incubating the HCV NS5B  polymerase with the primer-template in the presence and absence of a potential inhibitor, measuring the presence of any polymerase products formed in the presence and absence of the potential inhibitor; and comparing the amount of the polymerase products formed in the presence and absence of the potential inhibitor; wherein a decrease in the amount of the polymerase products formed in the presence of the potential inhibitor compared to the amount of polymerase products formed in the absence of the potential inhibitor is indicative of a potential primer-template binding inhibitor of HCV NS5B RNA  dependent RNA polymerase.

Title: Instrumentation for a downhole deployment valve
Inventor: HOSIE DAVID G
IPC: E21B47/12
Filed: 2003-11-05
Abstract: The present generally relates to apparatus and methods for instrumentation associated with a downhole deployment valve or a separate instrumentation sub. In one aspect, a DDV in a casing string is closed in order to isolate an upper section of a wellbore from a lower section. Thereafter, a pressure differential above and below the closed valve is measured by downhole instrumentation to facilitate the opening of the valve. In another aspect, the instrumentation in the DDV includes sensors placed above and below a flapper portion of the valve. The pressure differential is communicated to the surface of the well for use in determining what amount of pressurization is needed in the upper portion to safely and effectively open the valve. Additionally, instrumentation associated with the DDV can include pressure, temperature, and proximity sensors to facilitate the use of not only the DDV but also telemetry tools.

Title: Standardizing and calibrating a spectrometric instrument
Inventor: GANZ ALAN M
IPC: G01N21/25
Filed: 1993-01-15
Abstract: A spectrometric instrument which exhibits an intrinsic profile for a sharp spectral line produces profile data for narrow spectral lines. The spectral lines are effected with a high finesse etalon of gold coated polymer. A transformation filter is computed for transforming the profile data to a gaussian profile. A wavelength calibration is combined with the filter to effect a correction matrix which is applied to sample data to generate calibrated standardized data. Iteratively a correction matrix is applied to calibration data to generate standardized calibration data which is utilized for the wavelength calibration. Calibration is effected with an optical standard, an interference etalon and a fringe formula. Etalon effective thickness is first estimated and then precisely determined so that fringe peaks calibrate wavelength.
