    摘要: A system and method is disclosed for providing a firmware update to a device of a computer system in which a firmware update application and a firmware image are provided to a computer system. Verification steps are performed to insure that both the firmware update application and the user are authorized to perform the firmware update process. If the verification steps indicate that both the firmware update application and the user are authorized, the computer system is reset. During the boot process, the presence of the firmware update is recognized and the firmware update application is initiated, resulting in an update of the firmware of the device.

    摘要: An improved subsea manifold system that is capable of being used in an early production system for producing hydrocarbons from a plurality of wells from a common riser system. The subsea manifold is able to control the fluid from a multiple of subsea wet-tree wells while at the same time giving the operator the option to isolate production from a single subsea well for production evaluation. The subsea manifold also includes a pigging loop which enables efficient pigging of the flowline(s) of the early production system.

    摘要: An ambient light sensor testing module running on an information handling system verifies that an ambient light sensor managing brightness of an information handling system display is active and responding correctly. The testing module sets the display at first and second manually-selectable brightness levels and compares the brightness set from the first and second manually-selectable brightness levels when the ambient light sensor is engaged to set display brightness. An excessive difference between the brightness set by the ambient light sensor from the first and second manually-selectable brightness levels indicates a faulty ambient light sensor.

    摘要: A marine riser system for transferring fluid between a well on the seafloor and a vessel floating on the surface of the sea. The riser system has a turret buoy capable of connecting to a floating vessel; two or more hybrid risers, each of the hybrid risers having a vertical riser, a riser buoy attached to the upper portion of the vertical riser and a flexible jumper connecting the riser buoy to the turret buoy, and wherein the hybrid risers are secured to the seafloor. A flowline may connect a lower portion of each of the vertical risers to a subsea manifold, which interconnects the flowline and a subsea well. The subsea manifold is capable of controlling the flow to or from a subsea well. The hybrid risers are positioned about the turret buoy so that the turret buoy is horizontally balanced while disconnected from a vessel. In another embodiment, the marine riser system is capable of directing a fluid from the floating vessel to a subsea export flowline. In another embodiment, the present invention discloses a method of producing hydrocarbons from a subsea well, utilizing the marine riser system.

    摘要: An information handling system which supports Pre-Boot Authentication (PBA) and which provides the ability for each authorized user of the system to have a unique ID and key at the BIOS level. In these systems, a user only needs knowledge of the traditional BIOS password only at the time the user is enrolled in the PBA feature. Later changes to the password do not have the effect of denying access to enrolled users.

    摘要: In a method and system for authenticating a smart battery for charging, the smart battery receives an encrypted random string. The smart battery is operable to provide power to a device. The encrypted random string is generated by a controller of the device by generating a random string and encrypting the random string with an encryption key. The smart battery decrypts the encrypted random string with the encryption key to recover the random string and transfer the random string to the device. The device verifies that the random string is unchanged to authenticate the smart battery for the charging. If the random string has been modified then the smart battery is disabled from the charging.
