Abstract: A trailer door system that comprises at least one trailer door assembly operably engaged with the trailer; and at least one driving assembly operably engaged with the trailer and the at least one trailer door assembly. The at least one driving assembly further comprises an expansion assembly operably engaged with the at least one trailer door assembly. The at least one driving assembly further comprises a rotary actuator operably engaged with the expansion assembly, wherein the rotary actuator is configured to transition the expansion assembly between a collapsed position and an expanded position for pivoting the at least one trailer door assembly between a closed position and an opened position about an axis parallel to a vertical axis defined by the trailer. A trailer monitoring system may be included with the trailer door system for automating the state of the trailer during a towing operation.

Abstract: Methods, systems, and computer program products are provided for recovering from false positives of malware detection. Malware signatures that are defective may be causing false positives during software scanning for malware. Such defective malware signatures may be detected (e.g., by user feedback, etc.) and revoked. Computers that are using the malware signatures to detect malware may be notified of the revoked signatures, and may be enabled to re-scan content identified as containing malware using malware signatures that do not include the revoked malware signatures. As such, if the content is determined during the re-scan to not be infected, the content may be re-enabled for usage on the computer (e.g., may be restored from quarantine storage).

Abstract: An antifogging shield prevents fogging and condensation during surgery at a junction of surgical devices. The antifogging shield includes an antifogging shield body forming an interior chamber for accommodating a surgical tool therein and an insulation material disposed within the interior chamber to minimize temperature change.

Abstract: A drilling fluid and method of using same. The drilling fluid comprises water as a continuous phase, an amount of calcium chloride, and a quantity of a polyacrylamide copolymer. The amount of calcium chloride and the quantity of polyacrylamide copolymer in the drilling fluid are sufficient to produce a rate of penetration approaching that achieved using a synthetic oil-based drilling fluid while preventing substantial screen blinding. In a preferred embodiment, the continuous phase also comprises a second amount of a monovalent salt effective to increase gas hydrate suppression and decrease density when compared to a fluid consisting essentially of only a divalent salt in the absence of the monovalent salt.

Abstract: New compositions have been discovered which are useful as slurry concentrates to carry solid particles along in a fluid. A non-limiting example would be to carry proppants in a concentrate to a completion fluid being pumped downhole in a hydrocarbon recovery operation. The composition employs both a trivalent salt, such as aluminum chlorohydrate, as a viscosifying agent, and a surfactant. Surprisingly, it has been discovered that a synergistic effect is present between the aluminum chlorohydrate and the surfactant in that less of each component is required when both are used together to suspend the same amount of solids, than if one or the other is used separately. The viscoelasticity of the concentrate may be easily broken by dilution; other mechanisms are also anticipated.
