  • Patent number: 9659216
    Abstract: A method, computer program, and system for real-time signal analysis providing characterization of temporally-evolving densities and distributions of signal features of arbitrary-type signals in a moving time window by tracking output of order statistic filters (also known as percentile, quantile, or rank-order filters). Given a raw input signal of arbitrary type, origin, or scale, the present invention enables automated quantification and detection of changes in the distribution of any set of quantifiable features of that signal as they occur in time. Furthermore, the present invention's ability to rapidly and accurately detect changes in certain features of an input signal can also enable prediction in cases where the detected changes associated with an increased likelihood of future signal changes.

  • Patent number: 8694273
    Abstract: The present invention constitutes a method, processes, and apparatus for measurement and analysis of variables of different type and origin. In particular, the invention presents a method and apparatus for real-time signal conditioning and analysis in the presense of impulsive, or sparse interferences. The present invention overcomes limitations of the prior art by providing a novel method for identifying and discriminating between, in real time, the conditions of the signal with and without impulsive disturbances. This method can be implemented without substantial changes in the signal processing chain of a communication or data acquisition system. The present invention also overcomes the shortcomings of the prior art through the introduction of the novel SPART filters, which can replace the corresponding analog linear filters in the signal chain of a device.
