Title: Method and arrangement for nondestructive classification
Inventor: PERSTORPER MIKAEL
IPC: G01M7/02
Filed: 1997-06-17
Abstract: Method and device for nondestructive determination of rigidity, strength and/or structural properties of preferably oblong and/or plate-shaped objects (11), alternatively determination of the geometrical dimensions of the object, through impact excitation and registration of resonance frequencies of natural modes of the object. According to the invention resonance frequency from at least one of the natural modes of the object is used, which resonance frequency is achieved by bringing the object (11) in vibration by means of a stroking body (24, 31, 38), and substantially controlling the initiation of the motion of the stroking body (24, 31, 38) and subsequent physical impact in time and space by motion of the object (11).

Patent CA-2263244-A1 (CA)
Inventor: ZHANG QIN
IPC: H04L27/36
Filed: 1999-03-01
Abstract: The quadrature amplitude modulator of the present invention allows from 6 to 8 independent compressed channels to occupy a 6 MHz bandwidth while reducing processing power by 33 percent for 8 levels of modulation offered by 64-QAM and by 25 percent for 16 levels of modulation offered by 256-QAM. The QAM modulator is implemented with a reduction in the total number of binary parallel multipliers and the use of LUTs (look-up tables) storing precomputed filter weighting coefficients thereby increasing operational throughput. The reduction in multipliers is achieved by using post filtering carrier combination which similarly reduces the number of MAC (multiply and accumulate) operations performed during filtering. The invention can be implemented as an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).

Title: Method for the determination of analyte concentration in a lateral flow sandwich immunoassay exhibiting high-dose hook effect
Inventor: KUO HAI-HANG
IPC: G01N33/543
Filed: 1999-04-16
Abstract: Disclosed is a method for determining the concentration of an analyte in a fluid test medium by use of an immunochro-matographic test strip through which the test fluid can flow by capillarity. The test strip has at least two capture bands and optionally one or more collection bands which capture labeled anti-analyte antibody to provide a detectable signal.      The signals from the label is quantitatively detected in each of the bands to provide a pattern of signals which is unique to the concentration of analyte in the test fluid. The pattern of signals are mathematically combined to create a monotonous dose-response curve to thereby factor out the high analyte hook effect which can be present in this type of assay.

Patent CA-2271010-A1 (CA)
Inventor: REYNOLDS GARY MACK
IPC: A61F13/49
Filed: 1997-11-25
Abstract: The invention relates to methods of fabricating an absorbent article. In one method of the invention, combination containment flaps (98) and leg cuffs (100) are formed on a common substrate. A plurality of elastomeric elements (54) are included in the combination article to assist in forming containment flaps (98). Discrete leg cuff pieces are applied to the substrate at longitudinally spaced locations. In some embodiments, a cutting device slits the substrate substantially along a center line extending the length of the substrate, forming two continuous substrate portions. A glue gun (133) applies adhesive to the substrate portion. The substrate portions are folded lengthwise, using the adhesive to form integral containment flaps and leg cuffs in a composite substrate. The composite substrate is secured to an absorbent article web sausage in forming absorbent articles. In another embodiment, the substrate is a first substrate which supports elastomeric elements (54) used in forming leg cuffs (100) and containment flaps (98). The first substrate is secured to a second substrate, thus forming a base structure, with the elastomeric elements (54) between the first and second substrates. A bodyside liner and an absorbent core are added on one side of the base structure, and an outer cover is added on the second side, to form a web sausage. In both embodiments the web sausage is cut transversely at spaced locations along the length of the web sausage, to form absorbent articles.

Abstract: Antigen inducers producing vaccine precursors having high selectivity and specificity, vaccines, antibodies including idiotypic antibodies, neutralizing antibodies, and antitoxins. These inducers, which typically have the fundamental molecular structure represented by the general formula (3-a), induce the non-functional properties of complex high molecular-weight substances forming living organisms and nonliving matters into fundamental structural substances close to the expression of the functions as far as possible by regulating quantum thermodynamically and stoichiometrically expressed functions and morphogenesis of molecules to thereby produce vaccine precursors having high selectivity and specificity, vaccines, antibodies including idiotypic antibodies, neutralizing antibodies and antitoxins. Moreover, use is made of these substances in producing antibacterial agents, antiviral agents, neutralizing antibodies, antitoxins, anticancer agents, antiprotozoal agents against Plasmodium, Spirochaeta, etc., molecular discriminators, histocompatibility enhancers, immune response promoters or immune response regulators serving as labels for antibodies, tissues and organs, and complement chain reaction promoters.
Patent CA-2280974-A1 (CA)
Title: Pre-cast concrete decking for load supporting structures
Inventor: MUFTI AFTAB A
IPC: E01D19/12
Filed: 1998-02-26
Abstract: Pre-cast concrete panels (1) for use as deck components in a load supporting structure are constructed of non-metallic fibre reinforced concrete. Integral, transverse tension members (2) are located externally adjacent the lower support surfaces (lb) of the panels and connected to the panels at their outer ends (4). The tension members (2) carry compression forces applied to the panels by supporting an arching action, thereby avoiding the need to provide steel reinforcement across the entire interior of the concrete. This, in turn, reduces the risks of panel failure due to the corrosion of reinforcement steel located within the body of the concrete panel.
Patent CA-2281405-A1 (CA)
Inventor: JOLLIFFE CHARLES
IPC: H01J49/40
Filed: 1999-09-02
Abstract: A mass spectrometer system in which an ion beam from a collision cell, mass analyzer or other ion transmission device is directed into an ion guide formed by a set of spaced part conductive rings, for transmission into a TOF analyzer. The ion guide tapers in height from its entrance to its exit, so that the ion beam is reconfigured into a flat thin sheet of charge having a reduced height and increased width as compared with the original ion beam. The decrease in height reduces spacial dispersion of the ions, increasing the resolution of the TOF, while the increase in width decreases space charge effects, and increases detector dynamic range. Fragmentation of the ions can also be performed in the ion guide, removing the need for a separate collision cell.
