  • Patent number: 7487056
    Abstract: Precision and reliability of localization estimates derived from conventional localization systems are improved through a system and method for post-processing of initial localization data, even in environments which may include noise, reflections, or other interference. Such localization systems include conventional sound source localization (SSL) systems based on microphone array inputs, radio source location systems based on directional antenna array inputs, etc. In general, this post-processing system and method applies statistical real-time clustering to initial localization estimates, and then uses this real-time clustering in a multi-stage process to generate new localization estimates having improved precision and reliability relative to the initial localization estimates.

  • Patent number: 7395175
    Abstract: A digital data recording apparatus, which can record the exact acquisition time of data, a sampling data identification method thereof, and a program for identifying sampling data, are provided. A CPU 11 reads out the program of a first conversion formula. The CPU 11 uses the first conversion formula to convert a time series of detection temperature data into a time series of actual oscillation frequencies f? of a reference clock signal. At a subsequent step, the CPU 11 calculates the respective normal sampling timings employing the current time as a reference time by dividing a time series of count values by each of the actual oscillation frequencies f? corresponding to the respective count values.

    Abstract: A method and system are provided for automated diagnosis for a system. In one embodiment, the method includes providing a fault tree representation of the system, the fault tree specifying propagations of errors generated in the system by problems to produce error reports. At least some of the propagations have timing information associated therewith. One or more error reports having timing information associated therewith are received and analysed using the fault tree representation to determine a suspect list of problems. The suspect list contains those problems that could have generated errors to produce the received error reports compatible with the propagations in the fault tree, and consistent with the timing information associated with the propagations and the received error reports.

  • Patent number: 7379836
    Abstract: The present invention is directed to a method of identifying test devices having excessive leakage current and also includes computer program products that enable the same. The method obtaining background test data using a test routine to measure the leakage current for a set of test devices as a function of a parameter associated with device speed for the device under test. From the test data, a leakage threshold function is defined that correlates leakage current with the parameter associated with device speed. The test routine and the leakage threshold function are then input into an automated testing apparatus configured to execute the test on production or other devices. Devices are tested to determine leakage current over a range of parameter values associated with device speed. The devices are then screened using the leakage threshold function to determine the status of the device.

  • Patent number: 7363182
    Abstract: Systems and methods for correcting measurements of fluid flow using device-specific information to compensate for differences between individual devices of the same design. In one embodiment, a method includes providing device-specific calibration data; sensing a fluid flow; computing a measured fluid flow based on the sensed fluid flow, and correcting the measured fluid flow based on the device-specific calibration data. More particularly, the fluid flow measurement is corrected using correction factors that compensate for the use of a gas that is different from the calibration gas (CF0 (1+aF+bF2+cF3)), for device variations in sensor sensitivity (1+??R), and for variations in the split flow of fluid through the flow meter (1???ADC(Sp/100)2). The sensor and split flow correction factors may be used independently of each other in some embodiments.

  • Patent number: 7349826
    Abstract: A plurality of causal ladder is assembled in advance from component system events taken from previous system failures. The ladders classify the various transitions the system goes through from one set of observed states to another in multiple stages representing issues of differing urgency, importance and need for remediation. These stages are used at runtime determine the criticality of any abnormal system activity and to accurately predict the component failure prior to the system crashing. Each ladder comprises a plurality of elevated stages representing criticality of the problem. At runtime, the causal ladder engine correlates real-time events received from the system to stages of one or more pre-constructed causal ladders and identifies a probable problem (and/or the faulty component) from the corresponding causal ladder. The causal ladder engine also determines the stage of the problem from event occurrences. At each stage, a different potential solution is identified for the problem.

  • Patent number: 7343258
    Abstract: The present invention relates to a method for accurately calibrating fusion temperature in optical fiber splicing. With assistance of direct arc-recentering technique, two optical fibers are spliced and then continuously heated with a post-fusion process. In the process, the fusion temperature is automatically determined in terms of effective fusion currents, which is done by real-time monitoring the fusion time dependence of cladding diameter reduction. In comparison with model calculations, variations of fusion temperature caused by changes of electrode condition and operating environment, e.g. altitude, temperature and humidity are derived. To recover the optimal fusion temperature in various fusion processes, the calibrating results are automatically invoked to compensate fusion currents.

  • Patent number: 7343264
    Abstract: This patent refers to an electronic equipment unit, which is intended to collects, process and transfer data from a certain area, which it monitors, to a telemetry system. In more detail, data are collected from various intrusion monitoring sensors (e.g. infra-red or microwave detectors), water level detectors, smoke detectors, electrical supply watchdogs etc. These sensor are external and use the logic circuits of the printed circuit board. The above mentioned data are suitably processed by the unit and the output is sent to a telemetry system via an external interface box. The advantages of this patent is the small size of the device and the low cost of the construction and operation of the device. It integrates on one printed circuit board (PCB) the processor and the logic circuits of a variety of sensors. Owing to its small size, the device can be easily installed inside sealed cellular telephony antenna shelters (outdoor shelters).
