  • Publication number: 20250021325
    Abstract: An information handling system includes a memory and a processor. The memory stores a current basic input/output system (BIOS) firmware image. During a regular boot mode of the information handling, the processor creates a first set of tables associated with the current BIOS firmware image, stores the first tables to the memory, and receives a BIOS firmware update image. During a BIOS update boot mode of the information handling system, the processor creates a second plurality of tables associated with the BIOS firmware update image, and compares the first and second tables. In response to a difference being determined between the first and second tables, the processor aborts the BIOS update boot mode and generate an error log.

  • Patent number: 8232345
    Abstract: A solution with a salt-sensitive polymer binder for use in fibrous webs, where the binder contains a copolymer of carboxylic acid monomer units and ethylenically unsaturated monomer units. The binder solution is prepared by emulsion-polymerizing a copolymer and then neutralizing the copolymer with base to make it water soluble. The binders provide a higher wet strength in concentrated salt solutions than in deionized water, and are particularly suitable for strengthening nonwoven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.

  • Patent number: 8201163
    Abstract: In a Uniform Extensible Firmware Interface (UEFI) environment, a system management mode (SMM) driver and a non-SMM driver may be installed for the same hardware device. Until the SMM driver is available, the non-SMM driver is configured to conduct input/output (IO) transactions directly with the hardware device. The non-SMM driver can utilize native UEFI services to receive a notification that the SMM driver is available. Upon receiving such notification, (or if the SMM driver was already available before the non-SMM driver), the non-SMM driver is reconfigured to redirect all IO requests to the SMM driver, which then conducts the corresponding IO transactions directly with the hardware device. Redirecting all non-SMM IO requests for a hardware device to the SMM driver for the hardware device limits direct access to the hardware device to only one driver, the SMM driver, thereby facilitating the integrity or atomicity of IO transactions.

  • Patent number: 8193104
    Abstract: The present invention is directed to a cationic polymer emulsion binder that may be combined with a cationic active ingredient and used as a non-woven binder. This combination of cationic binder and cationic active ingredient may occur as a mixture of a cationic binder and at least one cationic active ingredient, which is then applied to loose fibers to form a non-woven; or the combination may occur after a non-woven is formed using a cationic binder, and said non-woven is then contacted with a cationic active ingredient. Non-woven wipes of the invention retain far less cationic active ingredients during use, resulting in less waste and less use of the active ingredients for the same effect as wipes made with anionic or non-ionic binders.

  • Patent number: 7582699
    Abstract: The present invention is directed to a fibrous substrate made of chemically bonded fibers, where the fibers are bound with a polymeric binder in an amount which is sufficient to bind the fibers together to form a self-sustaining web, and where the binder is characterized as having a wet tensile strength of greater than 4500 grams per inch (g/in) when measured at a 20 percent add-on on Whatman #4 CHR chromatography paper which is drum dried for 90 seconds at 210 to 215° F. and cured for 2 minutes at 300 to 325° F. Preferably the level of free formaldehyde in the fibrous substrate is less than 15 ppm. The emulsion binders of the invention may be used to bind fibers together in a substrate; may be used to bind pigment, colors or other substances to a substrate; may be used as a backing material; or may be used to finish or surface-treat a substrate.

  • Patent number: 7457945
    Abstract: 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.

  • Publication number: 20080214080
    Abstract: A salt-sensitive polymeric binder composition which includes a water soluble salt-sensitive polymer component, and a latex processing aid. The binder compositions of the invention exhibit good strength in salt solutions, yet are dispersible in the presence of water. The latex processing aid is effective to reduce the shear viscosity of the binder composition, enabling an aqueous solution of the binder to be sprayed onto an airlaid nonwoven web.

  • Patent number: 7249080
    Abstract: The present invention provides investment advice systems. One version of the present invention provides investment advice systems that allow a user to select one or more advisors from a list of investment advisors. According to this version of the invention, the end user can receive advice on a particular transaction either separately from each investment advisor or in consensus. The system offers advice in part on the user's portfolio, tax position and risk profile and in part on the advisors evaluation of current market conditions. Thus, when a user is considering making a transaction, the user can obtain advice that can take into portfolio information including a user's proposed transaction and/or user portfolio information. A user armed with the above-described customized advice can execute a specific transaction and have their portfolio updated to reflect execution of that (those) order(s).

  • Patent number: 6378068
    Abstract: A laptop computer system includes a protected mode microprocessor capable of operating in restricted and unrestricted modes, and an arrangement which in response to a predetermined condition saves information from the processor and then forcibly switches the processor to its unrestricted mode of operation. When running a multi-tasking operating system where an application program is being executed in a restricted mode, a suspend/resume operation can be carried out in which the system is substantially powered down and then powered back up, and will resume the interrupted application with the restricted mode back in effect. Further, set-up changes such as adjustment of the processor speed can be made without exiting the application program running in the restricted mode.

  • Patent number: 6282662
    Abstract: Method and apparatus for selectively overriding a prepackaged power management driver of a portable personal computer so that data transmitted to the CPIU of the computer by a device, such as a “real time” serial communicators device connected thereto, is not lost during the CPUs latency “wake up” period following a CPU power-down operation. An override system stored in memory comprises an override flag which may be set or cleared by a user or the computer. If the override flag is set, then the power management system is prevented from reducing power to the CPU so that the occurrence of a CPU latency period and thus potential for loss of data is avoided.
