Abstract: This disclosure is generally directed to systems and methods for determining a passage status of a train through a railroad crossing. In an example method, a railroad crossing status detector system provided in a vehicle may determine that a train is approaching the railroad crossing. The determination is made by evaluating a first detection signal received from a first train detection apparatus located on one side of the railroad crossing. The railroad crossing status detector system may then evaluate a second detection signal received from a second train detection apparatus located on the other side of the railroad crossing and determine that the train has traveled past the railroad crossing. The system may also evaluate one or both detection signals to determine whether the train is currently located at the railroad crossing or is backing up after traveling at least partway across the railroad crossing.

Abstract: Upon determining a confidence score for challenge biometric data for a user of an object is less than a first confidence threshold, a confirmation confidence score for the challenge biometric data is determined based on a remote confidence score for the challenge biometric data received from a remote computer. Upon determining that the confirmation confidence score is greater than a second confidence threshold, a user status of the user is determined based on an authenticator. The user status is one of authorized or not authorized. The second confidence threshold is less than the first confidence threshold. Upon determining that the confirmation confidence score is less than or equal to the second confidence threshold, the user status is determined based on supplemental biometric data. Object components are controller based on the user status.

Abstract: Upon determining a mobile object is approaching an ice layer above a body of water, a thermal image of the ice layer is obtained. The thermal image and ambient temperature data are input to a neural network that outputs a plurality of regions of the ice layer and respective estimated thicknesses for the regions. A classification for each region is determined based on its estimated thickness and the mobile object. The classification is one of preferred or nonpreferred. The classifications for the regions are output.

Abstract: At a first timestep, one or more first objects can be determined in a first fusion image based on determining one or more first radar clusters in first radar data and determining one or more first two-dimensional bounding boxes in first camera data. First detected objects and first undetected objects can be determined by inputting the first objects and the first radar clusters into a data association algorithm, which determines first probabilities and adds the first radar clusters and the first objects to one or more of first detected objects or first undetected objects by determining a cost function. The first detected objects and the first undetected objects can be input to a first Poisson multi-Bernoulli mixture (PMBM) filter to determine second detected objects, second undetected objects and second probabilities. The second detected objects and the second undetected objects can be reduced based on the second probabilities determined by the first PMBM filter and the second detected objects can be output.
