  • Patent number: 11504030
    Abstract: A method and system for heterogeneous event detection. Sensor data is obtained and divided into discrete data windows. Each data window is defined by and corresponds to a time period of the sensor data. A time-frequency representation over the time period is calculated for each data window. A filter mask is calculated based on the data window corresponding to the time-frequency representation. The filter mask is applied for reverting the time-frequency representation to a time representation, resulting in filtered data. Features, such as extrema or other inflection points, are identified in the filtered data. The features define events, and transforming the time-frequency representation back into the time domain emphasizes differences between more and less prominent frequencies, facilitating identification of heterogeneous events. The method and system may be applied to body movements of people or animals, automaton movement, audio signals, light intensity, or any suitable time-dependent variable.

  • Patent number: 11257509
    Abstract: Techniques for EMD-based signal de-noising are disclosed that use statistical characteristics of IMFs to identify information-carrying IMFs for the purposes of partially reconstructing the identified relevant IMFs into a de-noised signal. The present disclosure has identified that the statistical characteristics of IMFs with noise tend to follow a generalized Gaussian distribution (GGD) versus only a Gaussian or Laplace distribution. Accordingly, a framework for relevant IMF selection is disclosed that includes, in part, performing a null hypothesis test against a distribution of each IMF derived from the use of a generalized probability density function (PDF). IMFs that contribute more noise than signal may thus be identified through the null hypothesis test. Conversely, the aspects and embodiments disclosed herein enable the determination of which IMFs have a contribution of more signal than noise.

    Abstract: System, methods, and other embodiments described herein relate to improving calibration of an onboard sensor of a vehicle. In one embodiment, a method includes, in response to acquiring sensor data from a surrounding environment of the vehicle using the onboard sensor, analyzing the sensor data to determine calibration parameters for the onboard sensor. The method includes identifying a suitability parameter that characterizes how well the surrounding environment provides for determining the calibration parameters. The method includes generating annotations within a map that specify at least the suitability parameter for a location associated with the sensor data. In further aspects, the method includes identifying, from the map, a calibration route for the vehicle that is a deviation from a current route in response to determining that the calibration state of the onboard sensor does not satisfy the calibration threshold.
