Systems and methods are described for a system with circuit fault protection comprising a battery (106), an interrupting contactor (202A, 202B) electrically connected with the battery (106), and a controller (206). The interrupting contactor (202A, 202B) may be configured to electrically connect the battery (106) to an end of a load (102) in a closed state and to electrically isolate the battery (106) from the end of a load (102) in an open state. The controller (206) may, while the interrupting contactor (202A, 202B) is in a closed state, detect a fault in a circuit that includes the battery (106) and the interrupting contactor (202A, 202B). The controller (206) may further toggle the interrupting contactor (202A, 202B) to open in response to detecting the fault.

Aspects of the present application correspond to utilization of a combined set of inputs from simulation systems to generate or train machine learned algorithms for utilization in vehicles with vision system-only based processing. Aspects of the present application correspond to utilization of a set of inputs from sensors or sensing systems and simulation systems to create updated training sets for use in machine learning algorithms. The combined set of inputs includes a first set of data corresponding to vision system from a plurality of cameras configured in a vehicle. The combined set of inputs further includes a second set of data corresponding to simulated content systems that generate additional training set data including visual images and data labels to supplement the vision system data.

Fluid formulations, including low traction fluid, low viscosity motor fluid and high pressure viscosity coefficient fluid formulations, that may be used in vehicle drive trains are described herein. The fluid formulations include a base oil and an additive. The fluid formulations can increase efficiency, reduce friction, and extend drive cycles associated with vehicle drive units.

Aspects of the present application correspond to utilization of a set of inputs from vision systems to generate simulations or predicted paths of travel for dynamic objects detected from the vision systems. Illustratively, a service can process the set of inputs (e.g., the associated ground truth label data) collected from one or more vision systems (or additional services) to identify predicted paths of travel for any dynamic objects detected from the captured vision system information. Typically, a plurality of predicted paths of travels can be generated such that more than one path of travel may be considered to meet or exceed a minimal threshold. The resulting predicted paths of travel can be further associated with confidence values that characterize the likelihood that any one predicted path of travel for a detected dynamic object will occur. The generated and processed paths can be provided or used as inputs for additional systems, such as navigation systems/services, semi-automated or automated driving systems/services and the like.

An electromechanical actuation arrangement for a non-mass-balanced primary flight control surface establishes and retains a torsional preload between distributed actuator outputs to eliminate surface freeplay and increase mechanical impedance. Preload is retained mechanically via an interconnect shaft and/or electronically by closed-loop synchronization that maintains a commanded differential torque. An independent flutter-suppression device provides damping and/or locking upon oscillation detection or disconnection. The architecture supports multiple embodiments, including fewer motors than transmissions and a transmission without its own motor, and enables reduction or elimination of hydraulic systems for primary flight controls while meeting aeroelastic requirements under normal and single-fault conditions.

A computer-implemented method of determining an unstenosed model of a region of bifurcation in a mammalian vascular tree, comprising: receiving image data of said region of bifurcation; determining a vascular model representation of said region of bifurcation; generating an interpolated vascular representation passing between two branches of said bifurcation based on said vascular model representation; and comparing said interpolated vascular representation with said vascular model representation to obtain an estimate of stenosis through said region of bifurcation.
