Abstract: A portable information handling system's integrated keyboard stows keys into a retracted position when the portable information handling system transitions from an open to a closed position, such as by rotating a lid to a closed position relative to a chassis having the keyboard. A cover plate disposed in the keyboard engages the keyboard keys to retract the keys into the information handling system when the lid of the information handling system rotates to a closed position and releases the keys to be biased out from the information handling systems when the lid rotates to an open position.

Abstract: LCD panel white balance adjustment provides a desired brightness with minimal impact on optical performance by maximizing Red, Green and Blue gains of the LCD panel for a predetermined color temperature and then adjusting brightness with backlight current. For example, Red, Green and Blue gain settings are set at substantially their maximum value to achieve a color temperature of 6500 degrees and then brightness for the LCD panel is adjusted to substantially 200 nits with the gains remaining at maximized values.

Abstract: A method, system and program are disclosed for accelerating data storage in a cache appliance that transparently monitors NFS and CIFS traffic between clients and NAS subsystems and caches files in a cache memory by using a perfect hashing memory index technique to rapidly detect predetermined patterns in received packet payloads and retrieve matching patterns from memory by generating a data structure pointer and index offset to directly address the pattern in the datagram memory, thereby accelerating evaluation of the packet with the matching pattern by the host processor.

Abstract: A system and method are disclosed for managing the service connectivity of a mobile device to a plurality of connectivity services. A mobile device comprising a service connectivity manager accesses a repository of service connectivity management information. The service connectivity manager uses a first subset of the service connectivity management information to determine the connectivity services supported by a mobile device. A second subset of the service connectivity management information is then used by the service connectivity manager to determine the connectivity services supported by a predetermined network. The service connectivity manager then manages the service connectivity between the mobile device and the connectivity services supported by the predetermined network.

Abstract: The invention organizes various pricing tables and price adjustment tables and various products and purchasing organizations based on “who” (i.e. which purchasing organization) is purchasing “what” (i.e. which product). The invention utilizes a denormalized table to relate the “who” to the “what” using denormalized numbers. The invention further organizes various purchasing organizations and products into hierarchical tables. These hierarchical tables are called organizational groups and product groups. Various price adjustments may be specified for each level of the organizational groups and product groups hierarchies. The price adjustments for a particular purchasing organization are determined by retrieving the price adjustments for that particular purchasing organization as well as the price adjustments for organizational groups above the particular purchasing organization in the organizational groups hierarchy.

Abstract: A system and method is provided for determining the location of an object. A first transceiver is associated with an object to be located. The first transceiver comprises a first transmitter and a first receiver operable to transmit and receive signals using a first transmission protocol and a second transmitter operable to transmit signals using a second transmission protocol. A first signal is transmitted using the first signal transmission protocol and is received by the first receiver. The second transmitter is then used to transmit a second signal using the second transmission protocol in response to receipt of the first signal and the second signal is then processed to determine the location of the object. In some embodiments, the first transmission protocol is in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard and the second transmission protocol is in accordance with a Ultra-Wide Band (UWB) standard.

The isolation element provides isolation that inhibits electromagnetic propagation between the two antennas.

Abstract: A tape library is provided with a fixed coupling mechanism so that the tape library includes discrete locations via which power and communication are provided to an accessor. The use of such a coupling mechanism in a vertical tape library allows for the use of gravity to ensure that the accessor can couple with the fixed coupling mechanism even when no power is present in the accessor.

Abstract: A system and method is disclosed that allows ActiveX functionality to be conditionally invoked by a non-ActiveX-enabled browser, such as those based on Mozilla technology, through the implementation of user-defined controls to mitigate system security vulnerability. ActiveX controls can be identified from within a Mozilla-based browser and the user can be presented with a choice of actions instead of ActiveX controls being automatically downloaded and activated by a browser extension such as E View. By referencing one or more user-definable lists containing domains, URLs, and ActiveX controls along with their respective attributes the method of the invention allows a user to specify the preferred behavior of a non-IE browser when attempting to render Web pages containing ActiveX controls.

Abstract: An information handling system projector tracks lamp usage to generate a lamp order form for order of a replacement lamp when lamp usage is a predetermined usage. The lamp order form is automatically generated and displayed to include lamp usage and projector identification information so that a user need not manually input that information into an order form. A network module of the projector supports queries for lamp usage from a lamp management module running on an information handling system. A projector processor interfaced with the network module reads the lamp usage and projector identification information from firmware of the projector and provides the lamp usage and projector identification information to the lamp management module for automatic generation of the lamp order form display.

Abstract: A method, system, apparatus and computer program product for determining an optimal file operational time in a data storage system for use with a tape media storing data in a serpentine pattern on tape media is provided. The operational time is optimized based on a “sequence on tape” algorithm, a “minimum reversal of direction on tape” algorithm, or a “minimum delay to next data” algorithm. A model is used to determine the predicted performance of each of the algorithms, and the algorithm that provides the minimum overall operational time is chosen and applied for carrying out an operational process on the tape media.

Abstract: A system and method is provided for providing a user-interface comprising a visual display of the physical location of a plurality of I/O ports on the housing of a portable information handling system.

Abstract: An integrated transmit circuit includes a voltage controlled oscillator (702) for generating an input frequency signal (e.g., VCO) that is provided to a divide by two quadrature generator circuit (706) which generates therefrom in-phase and quadrature clocking signals (I, IB, Q, QB) that are applied to control a plurality of transmission gates (711-718) configured in a matched switching topology (710) so as to selectively pass pulses from the input frequency signal, thereby generating interleaved LO pulses (Ø1, Ø1B, . . . Ø4, Ø4B). By applying the interleaved LO pulses to control the transmission gates (26, 28, 30, 32, 34, 36, 38, and 40) in the upmixer (720), the +I, ?I, +Q, ?Q input signals are interleaved over a plurality of phases of a carrier period to produce differential outputs (42, 44).

Abstract: A switching power converter tracks a time-varying input voltage during each cycle of the input voltage to provide power factor correction. The switching power converter includes a switch with a frequency and duty cycle modulated control signal. The switch controls the transfer of energy between the input and output of the switching power converter. The frequency of the control signal is greater than a frequency of the input signal. The control signal frequency is modulated during each cycle of the input voltage so that energy transferred from the switching power tracks the energy supplied to the switching power converter.

Abstract: External airflow rates from floor vents that provide chilled air to information handling systems are measured with a disposable tool to ensure compatibility of the information handling systems' external air cooling constraints with the cooling capacity of the floor vents. For instance, an information handling system manufacturer sends a disposable tool formed from a cardboard box to a user location. The tool has an open bottom to fit over a floor vent and a slat cut in a side surface to move in response to airflow that enters at the bottom. Pre-calibrated markings associated with expected airflow rates for information handling system cooling floor vents measure airflow rates by the degree of slat movement so that the user location and manufacturer may confer to confirm the compatibility of the user location cooling capacity with selected information handling systems.

Abstract: Monitoring of boot progress for a multiprocessor information handling system is performed with a test module running on a CPLD. RAM integrated in the CPLD stores boot progress information passed through an I/O buffer located between the processors and the firmware that boots the processors. Downloading of the boot progress from the RAM to an external device, such as through a serial port, provides a processor trace that is analysis and debugging of the firmware by recording processor operations through the boot progress.

Abstract: A system and method for recovering from logical path failures is set forth. More specifically, when a host detects a logical path failure, the host enters a path discovery mode of operation. If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. Additionally, the system and method facilitates recovery of the failed logical paths by using a plurality of logical path masks. A first mask is referred to as an intermediate failure logical path mask and a second mask is referred to as a permanent failure logical path mask.
