  • Patent number: 11444757
    Abstract: Secure, semi-classical authentication schemes are presented. An authentication token is generated by applying a pre-determined measurement to a plurality of random quantum states to obtain a sequence of classical measurement outcomes. The token is validated by receiving the classical measurement outcomes and verifying whether the sequence corresponds to a statistically plausible result for the pre-determined measurement of the plurality of quantum states.
    Type: Grant

  • Patent number: 10044053
    Abstract: A method for starting operation of a solid polymer fuel cell from a temperature below 0° C. is disclosed that prevents certain problems with ice formation as the fuel cell thaws. During startup, the method involves providing the volumetric oxidant flow at a rate less than two thirds of its maximum when the coolant temperature is near 0° C.

  • Publication number: 20120094200
    Abstract: A method for starting operation of a solid polymer fuel cell from a temperature below 0° C. is disclosed that prevents certain problems with ice formation as the fuel cell thaws. During startup, the method involves providing the oxidant flow at a rate less than half of its maximum when the coolant temperature is near 0° C.

  • Publication number: 20110253291
    Abstract: The invention provides a drywall finishing method. The method may include the steps of taping one or more drywall joints with drywall tape and allowing drying; applying a coat of joint compound composition covering substantially all of the drywall tape and allowing to dry; and applying a finishing coat of joint compound composition to substantially all of a drywall surface and allowing to dry. The invention further provides a joint compound composition suitable for use in the method of finishing drywall, wherein the joint compound composition comprises a composition compatible with conventional jointing compound material and exhibits improved properties of thickness, self leveling, elasticity, durability, photographing and/or mold resistance over that of conventional joint compound compositions.

  • Patent number: 7483142
    Abstract: A security system uses a source capable of producing an entangled state of a sensing mode and a reference mode. The sensing mode has a path that enters an area around an object being secured. A state measurement system in the security system can measure a combination of the sensing mode after traversal of the sensing path and the reference mode after traversal of a reference path.
