Abstract: A method of determining a position of a train (localization) includes initializing a train position with no a priori position information (e.g., at power up), i.e., cold localization, and determining a train position within a known coarse region, i.e., warm localization. On-board sensors are used to detect landmark objects in a localization region of the guideway, based on distinct features of the landmark objects. Detectors detect object features and the object features are fused. Landmark objects are tracked over time in a unified local reference frame such that a sliding window of landmark objects is maintained as a local map. Object features of landmark objects in the local map are compared to a reference map in order to uniquely identify a corresponding constellation of landmark objects in the reference map.

Abstract: A method of detecting a way-side object includes receiving data frames from sensors mounted on a vehicle. Position data corresponding to the position of the vehicle is received. Object-of-interest data is retrieved from a database. The sensor data frames and the object-of-interest data are processed to determine a region-of-interest in the sensor data frame. A portion of the sensor data frames corresponding to the region of interest is processed using machine-learned object detection to identify a first object-of-interest. The portion of the sensor data frames corresponding to the region of interest is processed using computer vision methods to detect features of the expected object-of-interest and identifying the detected object-of-interest as explained when the features of the expected object-of-interest are detected. Explained object-of-interest data corresponding to the explained detected object-of-interest is output to a navigation system of the vehicle.

Abstract: A method of semantic object detection in an image dataset includes extracting semantic links relevant to the image dataset. Objects are detected in the image dataset and confidence scores are assigned to the detected objects. The semantic object detection compares the detected objects with the semantic links and augments the confidence scores based on the semantic links between the detected objects.

Abstract: A rinse ring system for use on a toilet. The rinse ring is a dual channel rinse ring, which allows the toilet to be flushed with either potable water from a fresh water system or with grey water from a grey water source. Other flush fluids are possible for use. The dual channel rinse ring provides separation between entry points for potable water rinse and the grey water rinse, preventing the possibility of contamination of the potable water source with grey water.
