Abstract: A valve body defines a work passage, a high-pressure channel fluidly connected to the work passage, a tank passage, and a cavity disposed between the high-pressure channel and the tank passage. The cavity fluidly connects the high-pressure channel and the tank passage. The cavity is defined at least in part by a first portion within which a relief valve threadedly engages, a second portion disposed adjacent to the high-pressure channel, and an annulus interposed between the first portion and the second portion. The annulus fluidly connects to the tank passage. A surface area of the relief valve exposed to the annulus is greater than a cross-sectional area of the high-pressure channel.

Abstract: An apparatus and method for providing a secure payment transaction on a mobile device are provided. The method includes determining, using a computer processor of the mobile device, whether a requested operation is a security sensitive operation, and when the requested operation is determined to be a security sensitive operation, executing the requested operation in a secure environment of the mobile device.

Abstract: A method and apparatus for data security incorporating device state. The method includes encrypting sensitive data written to an electronic device while the electronic device is in a locked state using a public key of an asymmetric master key pair. The method also includes, in response to detecting that the electronic device enters an unlocked state, converting asymmetric encryption of the sensitive data into symmetric encryption of the sensitive data using a symmetric master key. Encrypting of the sensitive data may include encrypting the sensitive data using a data encryption key (DEK) and encrypting the DEK using the public key. Converting of the asymmetric encryption of the sensitive data into the symmetric encryption may include decrypting the encrypted DEK using a private key of the asymmetric master key pair and re-encrypting the DEK using the symmetric master key without decrypting and re-encrypting the sensitive data.

Abstract: An apparatus and method for operating a relational database (DB) are provided. The method includes determining a sensitivity classification for a column of a table in the DB, performing encryption, using a data encryption key (DEK), of sensitive data when writing the sensitive data to the column determined to be sensitive, performing decryption, using the DEK, of the encrypted sensitive data when reading the sensitive data from the column determined to be sensitive, and performing writing to the column and reading from the column of unencrypted non-sensitive data when the column is determined to be non-sensitive.

Abstract: Disclosed herein are storm panels and methods for manufacturing the same. In one embodiment, the storm panel comprises a polymeric sheet having an arced geometry. The polymeric sheet comprises, a polymeric substrate layer, a polymeric top layer comprising an ultraviolet light stabilizer, a polymeric bottom layer comprising an ultraviolet light stabilizer. The storm panel has a uniform thickness, exhibits less than or equal to about 4.0 % haze, and exhibits a yellowness index shift that is less than or equal to about 9.0 after 1,500 simulated hours of aging.

Abstract: A plastic squeeze container for dispensing a fluid carrying a turret member rotatably mounted to the container for movement to a plurality of different rotational positions with the turret member carrying an outlet through which fluid may be dispensed generally along an outlet axis and with rotation of the turret member the outlet axis varying as to the angles it assumes relative to a vertical axis of the container.

Abstract: A spring mechanism comprising an elongate cantilevered spring member extending along a longitudinal coupled at a first end to a first member and with a distal, second end of the spring member engaging a second member such that the spring member biases the first and second members relative to each other. The spring member has an unbiased condition and being resiliently deflectable generally normal to its longitudinal to assume deflected conditions from which the spring member inherently attempts to return to its unbiased condition. The longitudinal of the spring member preferably remains disposed in a flat plane in deflecting of the spring member between the unbiased condition and the deflected conditions. The spring member preferably has, in cross-section normal to its longitudinal, a shape including two legs disposed to lie in planes parallel the flat plane and joined by a bight normal to the flat plane.
