Abstract: Systems and methods are provided for computing a secret shared with a portable electronic device and service entity. The service entity has a public key G and a private key g. A message comprising the public key G is broadcast to the portable electronic device. A public key B of the portable electronic device is obtained from a manufacturing server and used together with the private key g to compute the shared secret. The portable electronic device receives the broadcast message and computes the shared secret as a function of the public key G and the portable electronic device's private key b. The shared secret can be used to establish a trusted relationship between the portable electronic device and the service entity, to activate a service on the portable electronic device, and to generate certificates.

Abstract: Systems, devices, methods, and programming products for enabling read/write operations between near field communication (NFC) devices at multiple levels of access authorization.

Abstract: A key injection service module for an asset management system is provided for a secure means of injecting keys into products. To provide this service, a controller is used to define one or more key types defining the format of the keys in a file. The controller is then used to define a product model, and then to bind each key type to the product models.

Abstract: A method of relaxing naturally curly hair that comprises: A) carrying out a hair treatment session that comprises the steps of: i) applying to the hair, an alkaline hair relaxer comprising an active hydroxide, ii) allowing the relaxer to remain on the hair for a total period of less than about 10 minutes; iii) removing the relaxer from the hair; and B) repeating the treatment session described in part (A) to attain a desired degree of hair relaxation, with the interval between individual treatment sessions ranging from about 3 to about 20 days.

Abstract: The present invention provides a ring-containing component polyol and process for making the same for use as a load-bearing capacity improvement agent in flexible polyurethane foam manufacture. The ring-containing component polyol eliminates and/or reduces the need for a copolymer polyol containing suspended solids in the manufacture of flexible foam products. This may reduce production costs, reactivity variations, filter plugging, color variations, foam shrinkage/tightness, foam irregularity, and foam malodor while maintaining an adequate load-bearing capacity. The present polyol blends can be non-opaque or transparent.

Abstract: Disclosed are methods and compositions for preparing polyurethane foams using emulsified polyol mixture comprising (a) a polyol formulation comprising a polyester polyol having an OH value of from about 150 to 350; and (b) a cell opening agent.

Abstract: The present invention relates to water heater (12) construction whereby thermal insulation material is foamed in the clearance space between the tank and shell of the water heater, wherein the foamed insulation material has lesser uniformity in cell structure and density and a lesser or smaller density in the upper portion of the volume of foam which is disposed over the top of the inner water tank than in the lower portion of the volume of foam insulation material disposed around the side of the inner water tank. The present invention provides gas and electric water heaters with improved energy efficiency, utilizing a liquid, foam-in-place composite foam insulation system. The present invention further provides an improved method for insulating the annular clearance space between an inner water tank and an outer enclosure of a gas or electric water heater.

Abstract: A mild wave and hair styling reducing agent-containing composition and method of bodifying, styling, or permanently waving or straightening human hair that provides a strong, long lasting curl, or long lasting straight hair formation, while minimizing hair damage. The composition includes two ionic compounds, one cationic and the other anionic, that complex in solution over a molar ratio of cationic compound to anionic compound in the range of about 1:1.2 to about 1.2:1, preferably in the range of about 1:1.1 to about 1.1:1, to provide synergy in waving efficiency, thereby providing a strongly reconfigured hair configuration (curled or straightened). At least one of the ionic compounds functions as a reducing agent for hair, capable of breaking the disulfide bonds in the hair so that the bonds later can be reformed via oxidation, when the hair is in the desired configuration.
