  • Publication number: 20150066431
    Abstract: Use of a failure model is disclosed which can be used to probabilistically evaluate possible failure modes in the event of failure of a complex component when no forensic analysis of the failed component is performed. When component failures do occur, contemporaneous sensor and operation data may be used to update and refine the failure model, whether a forensic analysis of the failed component is performed or not. Further, when no component failure is reported, the contemporaneous sensor and operation data may be used to predict component failures.

  • Patent number: 8710976
    Abstract: A system, computer-readable medium, and method for updating a decisioning algorithm are provided. In the method, operational parameter data from a first device is evaluated using a decisioning algorithm to determine if an alert should be sent. The alert indicates a possible performance issue associated with a component of the first device. The operational parameter data includes a value of an operating characteristic of the first device. When a determination is made to send the alert, an alert message including a first indicator indicating the possible performance issue of the component of the first device is created. The alert message is sent to a second device. The decisioning algorithm is updated based on a second indicator received from a third device. The second indicator indicates either that the alert was useful or that the alert was not useful.

  • Patent number: 6898460
    Abstract: A system and a method are provided for processing electromyogram (EMG) input signals from an abdominal surface to detect uterine contractions. The system comprises a sensor configured to detect a uterine EMG signal and generate an EMG input signal. The system further includes a signal processor coupled to the sensor and configured to generate an EMG prediction error signal. The signal processor performs signal-processing operations on the EMG input signal to generate the EMG prediction error signal, where the EMG prediction error signal corresponds to the magnitude of at least one contraction event and the periodicity of multiple contraction events.

  • Patent number: 6404379
    Abstract: A method and system for identifying the locations of plural targets lying within a main beam of a monopulse antenna including four ports for generating sum, elevation difference, azimuth difference and double difference signals. The method comprises the steps of forming a monopulse ratio matrix from the sum, elevation difference, azimuth difference and double difference signals; and determining eigenvalues of the monopulse ratio matrix. These eigenvalues are then used to determine the angular locations of the plural targets. Preferably, the eigenvalues are determined by performing an eigenvalue decomposition of the monopulse ratio matrix to generate eigenvalues, and the angles of the targets may be determined from the eigenvalues by the use of a look-up table.
