  • Patent number: 6687640
    Abstract: A method and system for inferring airborne contaminant concentrations in rooms without contaminant sensors, based on data collected by contaminant sensors in other rooms of a building, using known airflow interconnectivity data. The method solves a least squares problem that minimizes the difference between measured and predicted contaminant sensor concentrations with respect to an unknown contaminant release time. Solutions are constrained to providing non-negative initial contaminant concentrations in all rooms. The method can be used to identify a near-optimal distribution of sensors within the building, when then number of available sensors is less than the total number of rooms. This is achieved by having a system-sensor matrix that is non-singular, and by selecting that distribution which yields the lowest condition number of all the distributions considered. The method can predict one or more contaminant initial release points from the collected data.

  • Publication number: 20040015316
    Abstract: A receiver/decoder (for example for digital television) normally receives and/or decodes transmitted data in a normal transmitted signal. In order to test an application running on the receiver/decoder, a special test signal could be generated, or a normal signal could be modified before supply to the receiver/decoder. However, this is costly and complex. To overcome these problems, the receiver/decoder simulates the reception of such transmitted data to produce simulated data; and the application to be tested processes such simulated data in addition to, or instead of, such transmitted data. Simulation may involve generating the simulated data in the receiver/decoder, or controlling the generation of the simulated data by a workstation and receiving the simulated data from the workstation. Data generation may employ a model of the transmitted signal, the model having various parameters which can be varied.

    Abstract: The invention discloses a system for improving performance of the RF amplification stage of communication receivers by accounting for the signal environment of the RF amplifier. The linearity, gain and power supply voltage of the RF amplification stage of the communication receiver is adjusted to produce an optimal signal into the succeeding narrow-band amplification stage(s). The adjustment of the RF stage includes mechanisms such as adjusting the RF amplifier power supply level using a DC to DC converter. It also includes allowing distortion in the RF amplification stage if the distortion in the RF amplification stage does not affect the target signal. For example, if there were a strong signal that fell within the same band as the target signal, amplification would be allowed to be so high that it distorted the undesired signals, but not the tined signals.

  • Patent number: 6542845
    Abstract: A method of concurrently performing a component test with returning test result data in a distributed environment is disclosed. In general, in order to assure compatibility of the various components in an enterprise computing system, a service test is created as part of a compatibility test suite and passed to a test application server having a test application program. The test application program makes an initial connection to the component being tested that, in response, creates a connection to a logging listener. The logging listener spawns an acceptor corresponding to the component being tested. Once spawned, the component returns test data to its corresponding acceptor concurrently with the execution of the test.

  • Patent number: 6542844
    Abstract: A method and apparatus for tracing hardware states using dynamically reconfigurable test circuits provides improved debug and troubleshooting capability for functional logic implemented within field programmable logic arrays (FPGAs). Special test logic configurations may be loaded to enhance the debugging of a system using FPGAs. Registers are used to capture snapshots of internal signals for access by a trace program and a test multiplexer is used to provide real-time output to test pins for use with external test equipment. By retrieving the hardware snapshot information with a trace program running on a system in which the FPGA is used, software and hardware debugging are coordinated, providing a sophisticated model of overall system behavior. Special test circuits are implemented within the test logic configurations to enable detection of various events and errors. Counters are used to capture count values when system processor execution reaches a hardware trace point or when events occur.

  • Patent number: 6516051
    Abstract: This invention relates to bulk testing of voice messaging applications by playing back an interaction from a recorded script. During development of a voice response system and application it is necessary to simulate a plurality of calls to the system so that the performance under strain can be monitored. Such a simulation can be performed by a bulk call generator which makes real telephone calls to the IVR through a private branch switch. However with bulk call testing some problems occur which rigorous functional and/or performance testing does not find. This is because real callers behave in unpredictable ways which were not expected or assumed by the creators of the functional and/or performance tests.
