Abstract: A vehicle may include a movable roof, a sensor supported by the roof, and an actuator for selectively raising and lowering the roof.

Abstract: A vehicle control system may include a vehicle having a propulsion unit and a steering unit, a forward-facing camera carried by the vehicle, a processor, and a non-transitory computer-readable medium comprising operator position identification instructions. The operator position identification instructions direct the processor to identify relative positioning of a remote operator on the ground proximate the vehicle based upon signals from the forward-facing camera; and control the propulsion unit and the steering unit of the vehicle to follow the operator based upon the relative on the ground proximate the vehicle.

Abstract: A vehicle is operable in a first mode in which vehicle actions are controlled in response to inputs received by an input device carried by the vehicle from an operator while being boarded on the vehicle and in a second mode in which vehicle actions are controlled in response to inputs received from the operator while the operator is proximate the vehicle, but no longer boarded on the vehicle. The vehicle carries a sensor configured to output a sensed input, as sensed by the sensor, from the operator proximate the vehicle, but not boarded on the vehicle. The sensed input is recognized and associated with a vehicle action and control signals are output to the vehicle based on the sensed input to cause the vehicle to carry out the vehicle action.

Abstract: An externally adjustable pressure regulator includes a body having a shoulder, a longitudinal axis and a high pressure inlet. The body has an opening along a side. A bonnet has a regulated pressure outlet and is engaged with the body. A piston is positioned in part in the body and the bonnet. The piston has a shoulder, a longitudinal bore and a transverse bore at about the end thereof in flow communication with the longitudinal bore. A spring is disposed on the piston. A wedging element is positioned in the opening in the body side and is in contact with the spring. An adjusting ring engages the wedging element to move it into the spring to increase compression of the spring and off of the spring to decrease compression. Increasing compression of the spring increases a spring force of the spring on the piston and decreasing compression of the spring decreases the spring force on the piston.

Abstract: A plant locating system may include a vehicle supporting a Global Positioning System (GPS) antenna and a monocular camera. The system may further include a plant locating unit comprising a processing unit and a non-transitory computer-readable medium containing instructions to direct the processing unit to: acquire a sample image of a plant of interest captured at a time with the monocular camera at an unknown distance from the plant of interest (POI); determine a geographic location estimate of the GPS antenna at the time; identify a selected portion of the sample image comprising the POI; determine a distance between the POI and the monocular camera based upon the selected portion; and determine a geographic location estimate of the POI based on the geographic location estimate of the GPS antenna at the time and the determined distance between the monocular camera and the POI.

Abstract: A computer implemented vehicle control method may include obtaining a sensed input from an operator remote from a vehicle, recognizing and associating the sensed input with a vehicle action and outputting control signals to the vehicle to cause the vehicle to carry out the vehicle action.

Abstract: A pressure release valve, having three or more cavities is described. The pressure release valve comprises a valve body with at least three valve cavities for fluid. The first valve cavity contains high-pressure fluid and the second cavity contains low-pressure fluid. The first, second, and third cavities are separate and apart from one another. The pressure release valve further includes a movable valve body shaft with a valve hammer and an elastic spring body. The pressure release valve further includes a channel and a valve port, wherein when pressure is applied to the movable valve body shaft, the movable valve body shaft is actuated to press against the valve hammer forcing the valve hammer to move opening the port allowing fluid to flow from the first cavity, to the second cavity and the third cavity.

Abstract: A technique includes clustering projects that include a new project and previous projects based on relationships between users and the previous projects to identify a project cluster containing the new project. The technique includes clustering the users based on relationships between the users and permissions that were assigned to the users to access resources for previous projects. The technique further includes assigning permissions for the users assigned to the new project to access resources associated with the new project based at least in part on the clustering of users and the clustering of projects.
