  • Patent number: 8344707
    Abstract: A power control system includes a current sense resistor located on an output side of a switching power converter. By locating the current sense resistor on the output side of the switching power converter, the current sense resistor conducts a sense current when a control switch of the switching power converter is nonconductive. Since a duty cycle of the control switch is larger for a low input voltage than for a higher input voltage, the current sense resistor conducts current for a shorter time duration for low input voltages than for higher input voltages. Thus, the root mean square (RMS) of a sense current in the current sense resistor and, thus, power dissipation by the current sense resistor, is lower during low input voltages than power dissipation in conventionally located current sense resistors. The RMS of the sense current is approximately constant across a full range of input voltages.

  • Patent number: 8340283
    Abstract: A client generates a session key and a delegation ticket containing information for a requested delegation operation. The client generates a first copy of the session key and encrypts it using a public key of a proxy. The client generates a second copy of the session key and encrypts it using a public key of a server. The client then puts the encrypted session keys and delegation ticket into a first message that is sent to the proxy. The proxy extracts and decrypts its copy of the session key from the first message. The proxy then encrypts a proof-of-delegation data item with the session key and places it and the delegation ticket along with the encrypted copy of the session key for the server into a second message, which is sent to the server. The server extracts and decrypts its copy of the session key from the second message and uses the session key to obtain the proof-of-delegation data. Authority is successfully delegated to the proxy only if the server can verify the proof-of-delegation data.

  • Patent number: 8335792
    Abstract: A method for enterprise application integration that uses “connectors” that can be instantiated via downloading (e.g., using Java® or other such technologies) to provide interfaces to respective disparate database systems. The databases systems may comprise any variety of now or heretofore known systems, e.g. SAP, Oracle, and so forth. The connectors can, for example, translate between a native language (or API) of the respective database systems and an internal language/protocol of the enterprise application integration system. To this end, the connectors can utilize a scripting language to access the respective database systems. Data retrieved from the database systems can be stored in a central data store in the form of RDF triplets, from which directed graphs can be generated for to generate presentations consolidated from the multiple database systems.

  • Patent number: 8332818
    Abstract: A computer-based automated testing framework tests a multimedia application (such as a Flash application running in a player module) that includes one or more Flash objects by executing test scripts in an external Java-based test module that uses proxy objects in the test module to represent the Flash objects in the player module. Correspondence between the proxy object and Flash objects is maintained by translating the first test script into a command, sending the command from the external test module to the player module, interpreting the command by accessing a lookup table at the player module, and then returning a value to the external test module in response to the command.

  • Patent number: 8330304
    Abstract: An information handling system component contained within an information handling system housing uses the information handling system housing as at least a portion of a safety enclosure for hazardous functions of the component. A lock out device disables the hazardous function if the information handling system housing is moved relative to the component. For example, an optical disc drive laser is disabled if a Hall effect sensor in the chassis of the optical disc drive no longer senses a magnet placed in a portion of the information handling system housing used to enclose the optical disc drive. Alternatively, the component couples to the information handling system housing to enclose the hazardous function within the interior of the information handling system housing so that the component is inaccessible from the exterior of the housing.

  • Patent number: 8332428
    Abstract: An arbitrary number of custom catalogs for an arbitrary number of customers can be published from a single database of seller catalog data. Custom browse hierarchies can be generated for each of the custom catalogs. The custom catalogs are subsets of the catalog database, and are generated in accordance with a set of rules that defines the scope of the content of the custom catalog. The rule sets define a series of sequential searches by which a subset of the product SKUs contained in the database are returned. A primary hierarchy is maintained that can have a scope coextensive with the primary database. Custom browse hierarchies can be pruned to render their scope approximately coextensive with each subset. The custom catalog subsets and the custom browse hierarchies are generated periodically through a virtual publication process.

  • Patent number: 8327177
    Abstract: A storage device, such as a hard disk drive or solid state drive, reduces energy consumption by entering a reduced power state after an inactivity time where the inactivity time is set based upon I/O commands received at the storage device. For example, where commands received at a storage device are characterized in a predetermined way in terms of read commands, such as a last received command as a read command or a ratio of read commands versus write commands, a first inactivity time is applied, while commands characterized in a predetermined way in terms of write commands have a second inactivity time applied. Using a greater inactivity time during read activities than during write activities provides improved performance with reduced power consumption.

  • Patent number: 8325195
    Abstract: Wireless communication of display information between an information handling system and display is supported by a direct connection between a graphics system of the information handling system and a transceiver of the information handling system. For example, the graphics system outputs pixel level display information through a cable directly to the transceiver. A converter on the transceiver converts the display information to network information, such as from a DisplayPort format to a PCI Express format, so the transceiver can send the display information through a wireless network, such as a personal area network, to the display. A display module located at the transceiver coordinates initiation of communication of display information from the graphics system to the display.

  • Patent number: 8327126
    Abstract: A processor has multiple cores with each core having an associated function to support processor operations. The functions performed by the cores are selectively altered to improve processor operations by balancing the resources applied for each function. For example, each core comprises a field programmable array that is selectively and dynamically programmed to perform a function, such as a floating point function or a fixed point function, based on the number of operations that use each function. As another example, a processor is built with a greater number of cores than can be simultaneously powered, each core associated with a function, so that cores having functions with lower utilization are selectively powered down.
