  • Patent number: 8045472
    Abstract: In one embodiment, a receiver on a credit-based flow-controlled interface is configured to free one or more data credits early when a data payload is received that incurs fewer unused data credits within a buffer memory that is allocated at a coarser granularity than the data credits. In another embodiment, header credits and data credits are dynamically adjusted based on actual packet data payload sizes.

  • Publication number: 20110256863
    Abstract: Generating a radio frequency test signal for a mobile wireless communication device from a set of scanned radio frequency data that represents a plurality of radio frequency channels over a sequence of time intervals. A segment of the set of scanned radio frequency data over a time interval is classified into one of several radio frequency environments. A subset of the segment of scanned radio frequency data is selected based on the classified radio frequency environment. A segment of the radio frequency test signal is generated using the selected subset of scanned radio frequency data. The steps of classifying, selecting and generating are repeated for each time interval in the sequence of time intervals. Classifying the segment of scanned radio frequency data into a radio frequency environment includes comparing a set of statistics extracted from the segment of scanned radio frequency data to pre-defined classification ranges.

  • Publication number: 20110255700
    Abstract: Among other things, techniques and systems are disclosed for detecting musical structures, such as downbeats. In one aspect, a method performed by a data processing device includes receiving an input audio signal. The method includes detecting a meter in the received audio signal. Detecting the meter includes generating an envelope of the received audio signal; generating an autocorrelation phase matrix having a two-dimensional array based on the generated envelope to identify a dominant periodicity in the received audio signal; and filtering both dimensions of the generated autocorrelation phase matrix to enhance peaks in the two-dimensional array. The meter represents a time signature of the input audio signal having multiple beats. Additionally, the method includes identifying a downbeat as a first beat in the detected meter.

  • Publication number: 20110258254
    Abstract: The present invention provides a method and apparatus for integrating applets running on a client with the application logic for applications running on a server. The mechanism of the present invention provides two significant advantages over the prior art: the synchronization of state, and the recognition of user actions in the browser including the invocation of the appropriate application logic in the server. Instead of using the FORM element available in HTML, individual active applets are available and may be created that obtain user input (e.g. a checkbox, textbox, button, etc.). A hidden applet called the Applet Group Controller is created which handles communication between the applets on the browser and the application logic on the server. The Applet Group Controller maintains an association with each applet that maintains the keys and values of any parameters and variables for the applet.

  • Publication number: 20110255687
    Abstract: An asymmetric (dual key) data obfuscation process, based on the well known ElGamal cryptosystem algorithm, and which uses multiplicative cyclic groups to transform (obfuscate) digital data for security purposes. In the present system the data need not be a member of the cyclic group, unlike in the ElGamal cryptosystem algorithm. Also, any one of several additional mathematical data transformations are further applied to the transformed data, thereby enhancing security of the transformed data.

  • Publication number: 20110256779
    Abstract: A plug assembly having a core structural member and methods for manufacturing such plug assemblies are provided. A plug assembly can include a core structural member defining an elongated component having a bore therethrough. Several conductors can be inserted through the bore to be coupled to conductive regions used to transfer data and/or power. The conductive regions can include a ring or band that is provided axially over the structural member such that an external surface of the band can transfer signals. Each conductive region can include an arm extending from an internal surface of the band along the axis of the structural member. The arm may extend to a tip of the structural member so that a connector passing through the bore of the structural member can be connected to the arm (e.g., soldered to a tip of the arm). The structural member can include slots for receiving each arm.

    Abstract: According to one aspect, a multifunctional computing device having a wireless communications processor (e.g., cellular processor) and an application processor (e.g., general-purpose processor such as a CPU) share a storage device that is associated with or attached to the application processor. An example of such a multifunctional computing device may be a Smartphone device having a cellular phone and handheld computer functionalities. There is no specific storage device directly associated with or attached to the wireless communications processor (hereinafter simply referred to as a wireless processor). Instead, the wireless processor communicates with the application processor via a high speed communications link, such as a USB link, to access code and data stored in the storage device (e.g., flash memory device) associated with the application processor.

  • Publication number: 20110258604
    Abstract: A tool for analyzing software is enhanced to provide multiple views of a stack trace, with each view having a different level of detail. Different views may be lightly simplified, moderately simplified, or heavily simplified. The display of a complete stack trace includes entries for all stack frames in the stack trace. The display of a simplified stack trace includes entries for fewer than all stack frames in the stack trace, thereby “hiding” or “collapsing” entries for some of the stack frames, relative to the complete stack trace display. After a user specifies a level of complexity with which to show a stack trace, the enhanced analysis tool GUI updates the stack trace display according to the specified level. A complexity level is associated with a set of heuristics that is used to create a view of a stack trace at that complexity level.
