  • Publication number: 20120057716
    Abstract: A quiet zone generation technique for acoustic/audio signals is proposed for mitigation of selected noise or interferences over limited areas in free space by injecting the very acoustic noise, interference, or audio feedback signals via iterative processing, generating quiet zones dynamically. This creates undesired noise-free quiet zones. Optimization loops operating iteratively to electronically process cancellation signals consist of three interconnected functional blocks: (1) an acoustic injection array, consisting of pick-up arrays to obtain the interference signals, beam forming networks for element weighting and/or re-positioning, and array elements for noise injections, (2) a diagnostic network with strategically located probes, and (3) an optimization processor with cost minimization algorithms to calculate element weights for updating.

  • Publication number: 20120036409
    Abstract: A sequence of symbol operations (a “schedule representation”) within a data storage device, wherein the operations are those used to process encoding or decoding operations of a forward error correction code (an “FEC code”) upon an arbitrary block of data of a given size (where size can be measured in numbers of symbols). The method is such that the schedule representation can be used to direct the processing of these operations upon a block of data in a way that is computationally efficient. Preferably, the same method can be applied to represent schedules derived from multiple different algorithms for the encoding or decoding of a code or for multiple different codes.

  • Publication number: 20110197740
    Abstract: An advanced channel storage and retrieving system is achieved that is capable of simultaneously transporting multiple-stream data concurrently, with encryptions and error detection and limited correction capability using wavefront (WF) multiplexing (muxing) at the pre-processing and WF demultiplexing (de-muxing) in the post-processing. The WF muxing and demuxing processing can be applied for multiple signal streams with similar contents and format such as cable TV delivery systems or multiple signal streams with very distinct contents and format such as Karaoke multimedia systems. The stored or transported data are preprocessed by a WF muxing processor and are in the formats of multiple sub-channels. Signals in each sub-channel are results of unique linear combination of all the input signals streams. Conversely, an input signal stream is replicated and appears on all the sub-channels.

  • Patent number: 7912893
    Abstract: A system, method, and computer program product is provided for publishing transcoded media content in response to publishing service requests from end users. A user request for media content is processed intelligently, either by directing the processing of the request to one of a set of transcoding servers so as to effectively balance the load among the servers, or by directing the processing of the request to an appropriate alternative means for satisfying the request. Transcoding tasks can be prioritized. In order to facilitate server selection, the current load on any particular transcoding server can be monitored in conjunction with a determination of the load to be created by a transcoding task. Transcoding can be performed on-demand or in a batch mode. Alternatively, a request can be satisfied by distributing media content that has already been transcoded and is resident in cache memory in anticipation of such requests.

  • Patent number: 7895129
    Abstract: An integrated shipping scheme enables seller users of a third-party payment service to facilitate shipping transactions in connection with payment transactions for items sold by the sellers. Shipping information is automatically gathered and/or entered by the seller via a computer interface hosted by the third-party payment service and sent “behind the scenes” to a selected shipping vendor. The shipping vendor processes the shipping information, and returns shipment data, including data to generate a shipping label. A web page containing the shipping label is then generated and served to a client operated by the seller and displayed on a browser screen, enabling the shipping label to be printed out by the seller. At the same time, electronic payment transfer operations are performed to effectively transfer payment from the seller directly to the shipping vendor via the third-party payment service in a manner that is transparent to both the seller and the shipping vendor.

  • Patent number: 7742411
    Abstract: A technique for managing traffic within a network processor integrated circuit (IC) involves establishing multiple queue groups, associating a different hardware counter with each queue group, and then using the hardware counters to support rate shaping and scheduling of all of the queues in the queue groups. For example, 512 queue groups of thirty-two queues each queue group are established for a total of 16,384 (16 k) different queues and a different hardware counter is associated with each queue group for a total of 512 hardware counters. The group-specific hardware counters are used to implement hardware-based rate shaping and scheduling of all 16 k queues in a resource efficient manner that supports high throughput, e.g., on the order of 40 Gbps.
