  • Patent number: 8139635
    Abstract: A computer-based method for encoding and decoding quantized sequences in Wyner-Ziv coding of video, bi-partite graph is used in an iterative process. The method takes as input to an encoder a sequence of quantized data from a finite alphabet, the sequence comprising a video frame. Another sequence of data, decoded from the prior video frame, is input to a decoder. A statistical model describing the statistical relationship between the quantized input sequence to the encoder and the input sequence to the decoder is input to both the encoder and the decoder. A minimum field size is estimated from the statistical model at the encoder and the decoder separately.

  • Patent number: 8134724
    Abstract: Disclosed is a system and method for optimizing submission of output jobs to a network of output devices, using an output job manager to assign jobs to devices. The assignments are done automatically, based on policies associated with users, output devices, organizations responsible for the output devices, and the system as a whole. User output preferences are expressed as one or more user policies. System and organizational constraints associated with users and output devices and the managing of groups of output devices are also expressed as policies. An optimizing scheduler calculates tradeoffs between user preferences, and factors in constraints to optimize submission of jobs to output devices, and to optimize use and wait times on the output devices.

  • Patent number: 8131938
    Abstract: In a computer system with a memory hierarchy, when a high-level cache supplies a data copy to a low-level cache, the shared copy can be either volatile or non-volatile. When the data copy is later replaced from the low-level cache, if the data copy is non-volatile, it needs to be written back to the high-level cache; otherwise it can be simply flushed from the low-level cache. The high-level cache can employ a volatile-prediction mechanism that adaptively determines whether a volatile copy or a non-volatile copy should be supplied when the high-level cache needs to send data to the low-level cache. An exemplary volatile-prediction mechanism suggests use of a non-volatile copy if the cache line has been accessed consecutively by the low-level cache. Further, the low-level cache can employ a volatile-promotion mechanism that adaptively changes a data copy from volatile to non-volatile according to some promotion policy, or changes a data copy from non-volatile to volatile according to some demotion policy.

  • Patent number: 8126762
    Abstract: A stabilization methodology and system component in Business Activity Monitoring and Management systems. This enables firms to use Business Activity Management (BAM) systems to manage business activity by only responding to monitored data when the overall business performance can be improved. This enables firms to identify appropriate tradeoffs between potentially conflicting objectives while meeting business objectives. Information from BAM systems are analyzed based on models of the business process and different information filter criteria are assessed for their impact on business performance indicators. Based on this, a filter criterion is chosen which is executed by an information filter. The outputs from the information filter are used as the basis for deciding the inputs for business process execution.

  • Patent number: 8121877
    Abstract: A policy-driven approach to Business Performance Management (BPM) evolution is to capture the mechanism of BPM solution evolutions. These policies are executed by the runtime infrastructure which transforms and interprets evolution policies and allows fine granularity controls on solution evolution. At transformation time, the relationship among the event processing progress and the runtime state is derived based on the observation model. Such relationship information allows verification of freshness of migrating data and parallelization of runtime state validation and event processing. Consistent and efficient evolution of BPM solutions transit while event processing is operational.

  • Patent number: 8115275
    Abstract: An antifuse having a link including a region of unsilicided semiconductor material may be programmed at reduced voltage and current and with reduced generation of heat by electromigration of metal or silicide from a cathode into the region of unsilicided semiconductor material to form an alloy having reduced bulk resistance. The cathode and anode are preferably shaped to control regions from which and to which material is electrically migrated. After programming, additional electromigration of material can return the antifuse to a high resistance state. The process by which the antifuse is fabricated is completely compatible with fabrication of field effect transistors and the antifuse may be advantageously formed on isolation structures.

  • Patent number: 8111755
    Abstract: A method and system for low-complexity Slepian-Wolf rate estimator in a hybrid Wyner-Ziv video encoder determines the minimum Slepian-Wolf code rate required to allow correct decoding. The Slepian-Wolf estimator does not assume ideality of source and side-information statistics and does not require the presence of a feedback channel from the decoder to the encoder in order to determine the correct Slepian-Wolf coding rate. Instead, it adapts to the statistical properties of the video steam. The Slepian-Wolf estimator provides very efficient compression performance while avoiding Slepian-Wolf decoding failures.

  • Patent number: 8090223
    Abstract: Systematic use of infrared imaging characterizes marks made on items and identifies the particular marking tool with better accuracy than use of visual imaging. Infrared imaging performed in total darkness eliminates shadows, glint, and other lighting variations and artifacts associated with visible imaging. Although normally used to obtain temperature measurements, details in IR imagery result from emissivity variations as well as thermal variations. Disturbing an item's surface texture creates an emissivity difference producing local changes in the infrared image. Identification is most accurate when IR images of unknown marks are compared to IR images of marks made by known tools. However, infrared analysis offers improvements even when only visual reference images are available.

  • Patent number: 8041571
    Abstract: A method and apparatus detect and localize electric faults in electrical power grids and circuit. High impedance faults are detected by analyzing data from remote sensor units deployed over the network using the algorithms of speech and speaker analysis software. This is accomplished by converting the voltage and/or current waveform readouts from the sensors into a digital form which is then transmitted to a computer located either near the sensors or at an operations center. The digitized data is converted by a dedicated software or software/hardware interface to a format accepted by a reliable and stable software solution, such as speech or speaker recognition software. The speech or speaker recognition software must be “trained” to recognize various signal patterns that either indicate or not the occurrence of a fault. The readout of the speech or speaker recognition software, if indicating a fault, is transmitted to a central processor and displayed to provide information on the most likely type of fault.

  • Patent number: 8024156
    Abstract: Computation of variance or variance of the autocorrelation over a moving window of various sizes of a signal containing noise and possibly a small digital signal provides a sensitive, frequency independent indication of the likelihood of the presence of a small pulse, chirp or even spread spectrum digital signal possibly obscured by noise or larger signals in the signal to much lower signal-to-noise ratios than previously possible. Large signals in the signal which may also obscure any small signal are removed to a different signal path from the noise and small signals by subtraction after compression and reconstruction of the large signal. The compression noise thus added to the signal may also increase sensitivity of the variance of the autocorrelation to small signals obscured by the large signals. Controlling storage in response to the computed variance or variance of the autocorrelation allows substantial avoidance or limitation of storage of signals which contain only noise.

  • Patent number: 8008724
    Abstract: In producing complementary sets of metal-oxide-semiconductor (CMOS) field effect transistors, including nMOS and pMOS transistors), carrier mobility is enhanced or otherwise regulated through the use of layering various stressed films over either the nMOS or pMOS transistor (or both), depending on the properties of the layer and isolating stressed layers from each other and other structures with an additional layer in a selected location. Thus both types of transistors on a single chip or substrate can achieve an enhanced carrier mobility, thereby improving the performance of CMOS devices and integrated circuits.
