  • Publication number: 20030091989
    Abstract: This invention relates to methods for rapid nucleic acid purification from sources heavily contaminated with high particulate material, such as cellular debris, and solids, including suspended solids. In particular, this invention provides methods for rapid, quantifiable recovery and purification of nucleic acids from a variety of sources heavily contaminated with solids, such as small organisms, tissue samples, samples of blood found on soil, or samples of washing from foods, which are frequently difficult sources for nucleic acid isolation due to their propensity to clog filters and columns. A device and kit are also provided.

  • Publication number: 20020193696
    Abstract: A system and method classify cardiac complexes based on cardiac information derived from two or more cardiac signals. Two or more cardiac signals containing cardiac complexes are monitored. A cardiac complex in the two or more cardiac signals is isolated in an analysis window. The morphology of the cardiac complex in each of the two or more cardiac signals is then compared to the morphology of a template cardiac complex representing a predetermined cardiac condition. Based on this comparison, the cardiac complex is classified as either belonging or not belonging to the predetermined cardiac condition.

  • Publication number: 20020090623
    Abstract: The present invention provide methods for utilizing spent leukodepletion filter devices as a source of material for the isolation and analysis of genomic DNA (gDNA), including polymorphism, genotyping, and pharmacogenomic studies. Cellular retentate with the filter contains leukocytes, which are lysed to release the nuclei. The nuclei are lysed or ruptured to release genomic DNA, which is then isolated and used for subsequent analysis.

  • Publication number: 20020091333
    Abstract: The present invention provides a system and a method for discriminating supraventricular tachyarrhythmias from ventricular arrhythmias during a tachycardia episode. First cardiac signals and second cardiac signals are sampled for cardiac complexes. A first feature on the first cardiac signal and a second feature on the second cardiac signal are utilized to determine an average time difference for a plurality of normal sinus rhythm complexes. A time difference between the first feature and the second feature is then determined for each cardiac complex of a tachycardiac rhythm. The cardiac complex is characterized as a ventricular tachycardia complex if the time difference exceeds the average time difference by a predetermined amount. Otherwise, it is classified as VT if its morphology after alignment is different from that during normal sinus rhythm.

  • Publication number: 20020085643
    Abstract: Previous MIMO systems have used spatially diverse antenna elements in order not to reduce the number of orthogonal channels that can be realised. The present invention recognises that this leads to large antenna sizes, as compared to multiple beam antenna systems which use closely spaced antenna elements. In order to provide a compact antenna unit, while still allowing a MIMO system to be exploited, the present invention recognizes that polarization diversity only can be used in a MIMO system without the need for spatially diverse antenna elements. Closely spaced antenna elements are used and this enables a compact MIMO antenna unit to be provided. In addition, such MIMO systems with polarization diversity but no spatial diversity can advantageously be used in line of sight situations and also combined with multi-beam antenna systems to further increase capacity.

  • Publication number: 20020054833
    Abstract: According to the present invention, there is provided a multiwell device including a multiwell plate having at least one well, wherein each well has an open end portion and a sealing mechanism disposed over each well. The sealing mechanism prevents the loss of contents from each well after the sealing mechanism receives and is penetrated by a material transfer device during a material transfer procedure. Additionally, the present invention provides for a sealing mechanism for being disposed over a plurality of wells of a multiwell plate. The sealing mechanism prevents loss of content from the wells during a material transfer procedure. The present invention also provides for a method of transferring material from the wells of the multiwell device including the steps of puncturing the sealing matrix with the material transfer device and preventing cross-contamination of the content with other wells.

  • Publication number: 20020050280
    Abstract: The paintbrush-cleaning device includes a housing with an open top, a bottom drain and a means to hold paintbrushes into the housing's central space, which has paintbrush-cleaning liquid therein. A pair of rotatable radial brushes brackets the paintbrushes in the central space and are powered by an electric motor connected to the housing. A number of spaced upwardly directed jet nozzles are disposed in the central space for directing streams of cleaning liquid under pressure upwards towards the paintbrushes. An impeller pump may be connected to a manifold in the central space, from which manifold the jet nozzles extend. Two radial brushes may be used, with the members disposed opposite each other adjacent the sides of the top opening.

  • Publication number: 20010039157
    Abstract: An allergen-barrier fabric includes a tightly-constructed fabric substrate, woven from 0 to 45% continuous synthetic filament yarns and 55 to 100% natural or synthetic spun yarns. The fabric substrate is finished to produce a fabric with a mean pore size of 4 to 10 microns, an air permeability of 0.5-25 cfm, a mean fabric flexibility of 0.5 to 6.5 grams (bending resistance), and a moisture vapor permeability in excess of 800 g/m2/24 hours. This fabric provides a barrier to mite-induced allergen particles. Various additional finishes can be included on the fabric. For example, an antimicrobial finish may be provided on the fabric to extend fabric wearlife by providing protection against mold and mildew. As another alternative, a fluorochemical finish can be provided to extend fabric wearlife by providing protection against fluid stains.
