Abstract: The present technology is directed to training and using a machine learning model to predict a likelihood of a counterfactual safety critical event in autonomous vehicle (AV) driving in a projected scenario occurring after a human takes over control of an AV. An AV management system can identify driving data collected from periods around an occurrence of a human take over event where a human takes over control of an AV. The AV management system can project a scenario that would have resulted if the human did not take over control of the AV based on the driving data and output a counterfactual safety score for the projected scenario. The counterfactual safety score can indicate a probability of a counterfactual collision between the AV and the at least one object in the projected scenario.

Abstract: This invention proposes a single-vector-based finite control set model predictive control for two parallel power converters, which adopts a centralized control structure to achieve accurate control of overall performance. It establishes predictive models for line currents and three phase-circulating currents and constructs a novel cost function that uses these currents as performance indices to implement the predictive control algorithm based on the proposed predictive models. The invention proposes dynamic weighting coefficients and adjustment principles to improve system control performance. A finite set output signal matrix containing important characteristic information of all alternative vectors is constructed to avoid redundant calculations in each control horizon, reducing computation time during practical implementation.

Abstract: A cold snare includes a spring tube, a drive wire, and a loop. The cable passes through the spring tube, and can perform reciprocating motion in a direction of a longitudinal axis of the spring tube. The loop is fixedly connected to a distal end of the drive wire. Therefore, when the drive wire performs reciprocating motion in the direction of the longitudinal axis of the spring tube, the loop synchronously performs reciprocating motion in the direction of the longitudinal axis of the spring tube along with the drive wire to achieve the purpose of controlling the loop to enter and exit the spring tube by the drive wire. By using a spring tube as an outer tube, the strength of the spring tube is higher than that of a plastic outer tube of an existing cold snare, which is helpful for the loop to cut when grabbing large polyps.
