  • Publication number: 20230031260
    Abstract: A vehicle computing system validates location data received from a Global Navigation Satellite System receiver with other sensor data. In one embodiment, the system calculates velocities with the location data and the other sensor data. The system generates a probabilistic model for velocity with a velocity calculated with location data and variance associated with the location data. The system determines a confidence score by applying the probabilistic model to one or more of the velocities calculated with other sensor data. In another embodiment, the system implements a machine learning model that considers features extracted from the sensor data. The system generates a feature vector for the location data and determines a confidence score for the location data by applying the machine learning model to the feature vector. Based on the confidence score, the system can validate the location data. The validated location data is useful for navigation and map updates.

  • Patent number: 6403179
    Abstract: A polygonal composite structure is formed using a filament winding process. The composite structure formed on a mandrel having a longitudinal axis, comprises an inner structural layer, an outer structural layer, and a plurality of corner pieces. The inner and outer structural layers are formed by winding a fibre reinforcement material, having a resin applied thereon, about a mandrel. The fibre reinforcement material is oriented at a winding angle relative to the longitudinal axis. Each of the plurality of corner pieces is located at each corner of the polygonal structure between the inner structural layer and the outer structural layer. Each of the plurality of corner pieces is oriented lengthwise along the length of the structure. The number of corner pieces is equivalent to the number of sides of the structure.
