  • System and method for adjusting information handling system over current protection with a common power cable
    Patent number: 8065539
    Abstract: An AC-to-DC adapter provides power to information handling systems at different power levels based on the power rating of the information handling system. An adapter manager sets a first lower level at an over current protection circuit unless the information handling system sends identification information that indicates the information handling system is rated to accept a second higher power level, such as by sending a low signal pulse through a serial communication line. While the identification information is present and external power is applied to the adapter, the adapter manager sets a second higher level at an over current protection circuit to allow output of a second higher power level.

  • System and method for electrical communication through a non-conductive information handling system chassis surface
    Patent number: 8064220
    Abstract: Electrical communication between an information handling system chassis having a non-conductive surface and processing components within the chassis is established through the non-conductive surface with conductive elements extending from a conductive pad. A protruding element extending from a conductive pad engages the conductive elements through the non-conductive surface when the protruding element is coupled to a cavity formed in the chassis. Alternatively, the protruding element extends from the chassis to couple to a cavity in the conductive pad. Processing components have electrical communication with the chassis through the conductive pad.

  • System and method for powering an information handling system in multiple power states
    Patent number: 8063619
    Abstract: Power is supplied to an information handling system chipset with a single voltage regulator having dual phases. A first phase of the voltage regulator provides power to a low power state power rail in an independent mode to support a low power state, such as a suspend or hibernate state. A second phase of the voltage regulator provides power to a run power state power rail in combination with the first phase by activation of a switch, such as a MOSFET load switch, that connects the low power state power rail and the run power state power rail. Voltage sensed from both power rails is applied to control voltage output so that the run power state power rail is maintained within more precise constraints than the low power state power rail.

    Patent number: 8060788
    Abstract: The present invention relates to signal handling in a host operating system process executing code portions of a single- or multi-threaded application and of the embedded guest operating system. When a signal is sent from the host operating system to the operating system process, the signal handler of the guest operating system will be invoked in a deterministic time, independent of the operating system process executing code portions of the application or of the guest operating system or executing system calls of the host operating system in a masked or non-masked operation.

  • System and method for dynamic loop compensation for voltage mode control
    Patent number: 8055916
    Abstract: A voltage regulator provides power to an information handling system component under management by a controller, such as a Buck circuit managed by a PID controller according to PID coefficient settings. An update module interfaced with the voltage regulator monitors operating conditions of the voltage regulator to update the coefficients used by the controller. For example, changes in the load applied to the voltage regulator and an inductance associated with the voltage regulator are used to periodically compute updated PID coefficients, which are then used by the controller to control the voltage regulator.

  • Subscriber identity module unlocking service portal
    Patent number: 8050705
    Abstract: An improved method and system for removing operating restrictions associated with a predetermined subscriber identity module (SIM) from a wireless device. A user is allowed to securely log onto a Web site that contains support information on subscription plans, billing, termination, penalties, and device-to-SIM unlocking. After satisfying any outstanding contract terms and payment of termination or device unlock fees, the user initiates a device-to-SIM unlock procedure. A client application on the wireless device securely transfers subscription, system, and SIM information to a device-to-SIM unlock system which uses the information to generate appropriate unlock codes. The unlock codes are then securely transferred to the client application, which processes them to remove operating restrictions associated with the predetermined SIM from the device and allow it to thereafter implement a plurality of SIMs.

  • System and method for automated population splitting to assist task management through analytics
    Patent number: 8051030
    Abstract: Task management supported by analytics has enhanced effectiveness through automated population splitting for generating models that predict task associated outcomes. Subpopulations are automatically analyzed for adequate sample size and selectively recombined based on characteristics of the subpopulations, such as to combine homogeneous subpopulations or to optimize a subpopulation characteristic. As an example, outbound calling campaign models are generated for time periods by splitting a sample population into time period subpopulations and combining subpopulation time periods having inadequate sample size so that combined subpopulations have a minimized total time period or greater similarity relative to other subpopulations.

  • Video optimized LCD response time compensation
    Patent number: 8049741
    Abstract: An improved system and method for selectively applying LCD Response Time Compensation (LRTC) to areas of an LCD panel containing video motion. Motion vectors contained within macroblocks in a compressed video stream are utilized to qualify whether individual pixels in a video frame are a candidate for LRTC. In various embodiments of the invention, computationally expensive LRTC can be selectively applied, pixel-by-pixel, which can result in portable information system power savings by reducing the number of computational cycles and the amount of graphics controller power overhead.

  • Low profile, folded antenna assembly for handheld communication devices
    Patent number: 8044863
    Abstract: An antenna assembly is formed on a rectangular polyhedron support that has two sections projecting away from opposite sides of an electrically non-conductive substrate. An electrically conductive stripe wraps around the support and comprises a plurality of segments on different surfaces of the support. A conductive patch is located on two surfaces of the support to provide impedance matching between the antenna and a radio frequency circuit. By placing sections of the antenna assembly on both sides of the substrate and wrapping the conductive stripe around those sections, the space required to accommodate the antenna assembly within a housing of a communication device is reduced, as compared to some prior antenna designs.

  • Test systems for media drives of data storage systems
    Patent number: 8046187
    Abstract: A test system is described for testing a media drive, such as a tape drive. The test system includes a host emulator, a storage library emulator, and a control system. The host emulator communicates with a first interface of the media drive and mimics a host system to the media drive. The storage library emulator communicates with a second interface of the media drive and mimics a storage library system to the media drive. When in operation, one of the host emulator and the storage library emulator transmits a test message to the media drive responsive to an instruction from the control system. Responsive to the test message, one of the emulators receives a test response from the media drive and transmits the test response to the control system. The control system processes the test message and the test response to evaluate the performance of the media drive.

  • System and method for managing storage device capacity use
    Patent number: 8046597
    Abstract: Information handling system storage devices are managed to reduce power consumption by consolidating stored information to less than all of plural storage devices and powering down the storage devices that are no longer storing information. If a predetermined buffer of unused capacity is detected at the storage devices, then a powered down storage device is powered up to store additional information. The storage devices are consolidated to maintain desired performance parameters, such as by monitoring I/O performance for information stored on active storage devices.
