Abstract: A valve actuator includes a motor, an AC power source, a DC braking system, and a control system. The control system is configured to control the AC power source to apply an AC voltage to the motor to drive a valve toward a closed position. The control system is configured to disconnect the AC voltage from the motor before the valve reaches the closed position. The control system is configured to control the DC braking system to apply a DC voltage to the motor to stop motion of the valve.

Abstract: Systems and methods for maintaining autonomous vehicle operator awareness are provided. A method can include determining, by a computing system, an awareness challenge for an operator of a vehicle. The awareness challenge can be based on object data. The awareness challenge can have one or more criteria. The criteria can include a challenge response interval, a response time, and an action for satisfying the awareness challenge. The method can include initiating, by the computing system, a timer measuring elapsed time from a start time of the challenge response interval. The method can include communicating to the operator, by the computing system, a soft notification indicative of the awareness challenge during the challenge response interval. The method can include determining, by the computing system, whether the operator provides a user input after the response time interval and whether the user input corresponds to the action for satisfying the awareness challenge.

Abstract: An automated computer-implemented method for generating commands for controlling a computer numerically controlled milling machine to fabricate a machined object from a workpiece, the machined object being configured to facilitate subsequent finishing into a finished object, the method including defining a surface of the finished object, defining an offset surface defining an inner limiting surface of the machined object, defining a scallop surface defining an outer limiting surface of the machined object and calculating a tool path for the milling machine which produces multiple step-up cuts in the workpiece resulting in the machined object, wherein surfaces of the machined object all lie between the inner limiting surface and the outer limiting surface and the number of step-up cuts in the workpiece and the areas cut in each of the step-up cuts are selected to generally minimize the amount of workpiece material that is removed from the workpiece.

Abstract: Systems, methods, tangible non-transitory computer-readable media, and devices associated with the operation of a vehicle are provided. For example a vehicle computing system can receive occupancy data that includes information associated with occupancy of a vehicle that includes seats. One or more states of the vehicle can be determined. The states of the vehicle can include a disposition of any object that is within the vehicle. Further, a configuration of the seats in the vehicle can be determined based on the occupancy data and the states of the vehicle. The configuration can include a disposition of the seats inside the vehicle. Furthermore, at least one of the seats can be adjusted based on the configuration that was determined.

Abstract: A firearm with ambidextrous bolt catch has a frame, a bolt catch connected to the frame and movable between a retracted position and a restraint position, the bolt catch having exposed interface surfaces on a first side of the frame and configured to enable user contact to motivate the bolt catch to the retracted position and the restraint position, a secondary bolt catch interface assembly operable to motivate the bolt catch to the retracted position and to the restraint position, the secondary bolt catch interface assembly including an actuator having an actuation surface on a second side of the frame, and the actuator operable to move the bolt catch from the restraint position to the retracted position in response to a first actuation effort, and to move the bolt catch from the retracted position to the restraint position in response to a different second actuation effort.

Abstract: Systems and methods for automatically adjusting the interior cabin of an autonomous vehicle are provided. In one example embodiment, an autonomous vehicle can include a main body including a floor and a ceiling that at least partially define an interior cabin of the autonomous vehicle. The autonomous vehicle can include a partition wall that is movable within the interior cabin of the autonomous vehicle. The partition wall can extend between the floor to the ceiling of the main body. The autonomous vehicle can include a computing system configured to receive data indicative of one or more service assignments associated with the autonomous vehicle and to adjust a position of the partition wall within the interior cabin based at least in part on the one or more service assignments.

Abstract: A munition has an explosive charge with direction explosive characteristics, such as a nonuniform detonation velocities. The explosive charge may have multiple portions of explosives with nonuniform characteristics, and/or may have portions with graded nonuniform characteristics. The explosive charge may be used to propel a material from the munition in a desired manner. For example the material may be fragments that are part of a fragmentation munition. Alternatively the material may be a layer of a material, such as a metal, that produces an explosively formed penetrator or shaped charge. The explosive charge may be configured to control the spread and/or direction of the material to be propelled from the munition.
