Abstract: A flight control computer for controlling an actuator responsive to a flight control command is described. The system includes a first, second, and third pair of processors. Three different processor types make up the three pairs of processors and the pairs of processors differ between all processor pairs. A method aspect of providing a robust flight control computer controlling actuator responsive to a flight control command includes arranging interconnected pairs of processors using different processor types such that the pairs of processors differ between all processor pairs. An identical flight control command is received at each processor pair. A processor pair is declared to be in failure and processing is transferred to another processor pair if the compared output of each processor pair after receiving the identical flight control command differs between the processors in the pair.

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 system for controlling a vehicle includes at least one vehicle network on board the vehicle, first and second controllers coupled to the at least one vehicle network and configured to communicate with each other via the at least one vehicle network, and first and second sensor sets coupled to the at least one vehicle network, and configured to communicate with any of the first and second controllers via the at least one vehicle network. Each of the first and second controllers is configured to, based on data output from any of the first and second sensor sets, control a movement of the vehicle independently of the other of the first and second controllers. The first sensor set is located at a first location on the vehicle, the second sensor set is located at a second location on the vehicle, and the second location is different from the first location.

Abstract: A standalone odometry device includes an accelerometer and/or gyroscope configured to be mounted on a wheel or axle of a vehicle. A controller in communication with the accelerometer and/or gyroscope is configured to receive data from the accelerometer and/or gyroscope. The controller processes the data to determine one or more of the speed, wheel rotation direction, accumulated distance travelled, stationary status, acceleration, deceleration, wheel diameter, and grade of surface on which the wheel is in contact.

Abstract: A system comprises a first sensor on a first end of a vehicle and an on-board controller coupled to the first sensor. The first sensor is configured to detect a radio frequency (RF) signature of a marker along a guideway. The first sensor is a radar detection device. The on-board controller is configured to determine a first position of the vehicle on the guideway or a first distance from the position of the vehicle to a stopping location along the guideway based on at least the RF signature received from the first sensor. The marker is a metasurface plate comprising a first diffused element, a first retroreflector element, a first absorbing element and a second diffused element between the first retroreflector element and the first absorbing element.

Abstract: There is provided a method and system for providing a recommendation for a given problem by using a set of supervised machine learning (ML) models online by performing dynamic model evaluation and selection. An optional knowledge capture phase may be used to train the set of ML models offline using passive and/or active learning. Upon detection of a suitable initialization condition, the set of ML models is provided for inference and a feature vector is obtained. A set of predictions associated with accuracy metrics is generated by the set of models based on the feature vector. The accuracy metric may be global or class-specific. A recommendation is provided based on at least one of the set of predictions. The recommendation may be provided by selecting a best model, or by performing a vote weighted by the accuracy metrics. The set of ML models is retrained after obtaining an actual prediction.

Abstract: A communication system for a guideway mounted vehicle includes a control system communication system configured to exchange information between the guideway mounted vehicle and an external control system. The communication system further includes a vehicle-to-vehicle communication system configured to exchange information between the guideway mounted vehicle and another vehicle along the guideway, wherein the vehicle-to-vehicle communication system is separate from the control system communication system, and the vehicle-to-vehicle communication system is configured to exchange information directly between the guideway mounted vehicle and the other vehicle. The communication system further includes a vital on-board controller (VOBC) configured to generate instructions for controlling the exchange of information between the guideway mounted vehicle and the control system through the control system communication system, and to generate instructions for controlling the exchange information between the guideway mounted vehicle and the other vehicle.
