Abstract: An electronic monitoring system is disclosed for detecting the open and closed conditions of containers or cabinets containing confidential or classified information. The electronic monitoring system includes a current sensor that detects the presence of a locking bar secured to the containers. A current sensor located on each cabinet operatively cooperates with the transmitter that transmits a signal to a central location, which provides an indicator of the secured or non-secured condition of the container.

Abstract: A method and apparatus for computer-assisted project analysis. Planned values for successive times for each of a plurality of parameters are stored in a database. Another database receives measured values of the parameters at the successive times. A statistical analysis including comparison, correlation and differentiation functions generate a set of output functions that then are displayed to assist in the analysis of the project.

Abstract: A system/method of establishing a two-way communication system between a testing/manufacturing site and a component vendor is disclosed. The system allows the test results related to a component failure to be immediately available to a vendor by allowing the vendor password protected access to a product database that contains information regarding the product being tested. The system automatically alerts the vendor associated with the defective component, and allows the vendor to download the vendor's failure analysis report to the product database as soon as it becomes available. Upon receipt of the vendor's failure analysis report, the appropriate testing/manufacturing personnel are notified.

Abstract: A system and method for a neural network is disclosed that is trained to recognize noise characteristics or other types of interference and to determine when an input waveform deviates from learned noise characteristics. A plurality of neural networks is preferably provided, which each receives a plurality of samples of intervals or windows of the input waveform. Each of the neural networks produces an output based on whether an anomaly is detected with respect to the noise, which the neural network is trained to detect. The plurality of outputs of the neural networks is preferably applied to a decision aid for deciding whether the input waveform contains a non-noise component. The decision aid may include a database, a computational section and a decision module. The system and method may provide a preliminary processing of the input waveform and is used to recognize the particular noise rather than a non-noise signal.

Abstract: A computerized system and method are provided that may be used to project a plurality of risk levels that may develop during the course of a large development project. A plurality of inputs are stored and converted for use to a metric that is used by an expert knowledge rule based system to determine a plurality of risk levels that develops relating to successful completion of a large development program with respect to elements such as cost, time of delivery, and quality. A plurality of outputs are provided in a form that can be used by a program manager to reduce the level of risk that may arise. In a preferred embodiment, the plurality of outputs are provided in a quantified manner that may relate to a probability of failure of one or more aspects of the development program. The rules are based on the knowledge and experience of experts and are predetermined so that risk levels are objectively quantified prior to beginning the project rather than subjectively determined during the course of the project.

Abstract: The present invention relates to an intelligent personal underwater monitng system which recognizes when a swimmer is in trouble and transmits a warning signal. The system comprises a device worn by the swimmer which senses water pressure and transmits a first signal when a predetermined depth is passed by the swimmer. The system further comprises a device for receiving the signals generated by the device worn by the swimmer and a neural network processor for processing the signals and generating an output signal representative of whether the swimmer is in trouble and an alarm signal generation device.

Abstract: A receiver and method are disclosed that improves signal detection in a mipath environment wherein the desired reflected acoustic pulse is degraded by multipath reflections and embedded in noise. The invention provides a receiver that repetitively processes the received signal. The receiver includes separate signal processors, such as parallel configured quadrature signal processors, wherein each processor operates over different, and preferably contiguous, time intervals. After each repetition, the processing time interval for each processor is changed. The outputs of the processors are combined, such as by summing, and applied to a detector, such as a threshold detector, for each processing repetition to determine if the transmitted pulse is detected. The receiver continues processing the received signal until a predetermined number of time intervals have been processed without detection of a pulse or until the reflected pulse is detected.

Abstract: A test kit for measuring vapor emission from a concrete floor or other planar surface prior to installing a flooring material includes a relatively rigid dome-shaped cover having an outer bottom rim for seating with the planar surface to be tested when the cover is placed on the surface over an uncovered container of moisture absorptive material such as calcium chloride. The test kit further includes a weight ring that is removably placed onto a shoulder portion of the cover located at the cover's outer bottom rim. Placement of the weight ring on the dome-shaped cover during tests acts to hold the outer bottom rim of the cover in seating contact with the test surface. The test kit is easy to use and provides for reusable components. It can also be used without leaving a residue on the test surface.

Abstract: A likelihood of detecting a reflected signal characterized by phase discontinuities and background noise is enhanced by utilizing neural networks to identify coherency intervals. The received signal is processed into a predetermined format such as a digital time series. Neural networks perform different tests over arbitrary testing intervals to determine the likelihood of a phase discontinuity occurring in any such interval. An integration time generator subsequently uses this information to define a series of contiguous coherency intervals over the duration of the received signal. These coherency intervals are then used for piece-wise processing of the received signal by parallel quadrature receivers. The outputs are combined and processed for detecting the presence of the reflected signal.
