  • Publication number: 20090304985
    Abstract: A sectional floor mat system of floor mats and edging sections or pieces that are removably engaged with the floor mats. The floor mat system includes at least one mat and sufficient edging to border at least one of the side edges of the at least one mat. In many embodiments, there is sufficient edging to border all side edges of the at least one mat, when multiple mats, if present, and connected together. The edging pieces of the invention, and other variations thereof, when combined with mats, provide a floor covering system that is easy for the user to set-up, disassemble as needed, and inhibit tripping on the edges of mats.

  • Publication number: 20090081798
    Abstract: The invention relates generally to a new functional protein S assay and kit that is based on the ability of endogenous protein S to prolong clotting time. In the assay procedure, a test plasma sample is diluted with protein S deficient plasma, followed by the addition of purified or recombinant tissue factor (pTF or rTF), purified natural or synthetic phospholipid (pPL or sPL) and activated protein C (APC) or protein C activator (PCA). The clotting time is then measured and compared to a standard curve or a normal control.

  • Publication number: 20070146946
    Abstract: A leakage current detection interrupter with fire protection means, comprising: (i) a leakage current protection circuit, (ii) an electrical cord with metallic fire shields, and (iii) a fire protection circuit, wherein, in operation, the leakage current protection circuit and the fire protection circuit detect a fault condition including a leakage current, a ground fault and a fire hazard, and disconnect the source of electricity from the at least one user accessible load when leakage current, ground fault or fire hazard is detected. The electrical cord with metallic fire shields, the fire protection circuit, and the indicator circuit can be combined with any ground fault circuit interrupter, arc fault circuit interrupter, immerse detection circuit interrupter, appliance leakage current interrupter and electronic leakage current interrupter.
