Abstract: Systems and methods for vehicle controllers for agricultural and industrial applications are described. For example, a method includes accessing a map data structure storing a map representing locations of physical objects in a geographic area; accessing current point cloud data captured using a distance sensor connected to a vehicle; detecting a crop row based on the current point cloud data; matching the detected crop row with a crop row represented in the map; determining an estimate of a current location of the vehicle based on a current position in relation to the detected crop row; and controlling one or more actuators to cause the vehicle to move from the current location of the vehicle to a target location.

Abstract: Systems and methods for agricultural lane following are described. For example, a method includes accessing range data captured using a distance sensor connected to a vehicle and/or image data captured using an image sensor connected to a vehicle; detecting a crop row based on the range data and/or the image data to obtain position data for the crop row; determining, based on the position data for the crop row, a yaw and a lateral position of the vehicle with respect to a lane bounded by the crop row; and based on the yaw and the lateral position, controlling the vehicle to move along a length of the lane bounded by the crop row.

Abstract: A current control that employs a magnetic amplifier and an active feedback circuit. The feedback circuit establishes the effective operating current of the amplifier at a fixed point. The magnetic amplifier includes a pair of oppositely wound gate windings, a bias winding and a control winding. The gate windings are driven by an oscillator driver that generates a gate winding current and a gate winding voltage. A reference voltage and the gate winding voltage are applied to a feedback amplifier and the feedback circuit. When the gate winding voltage becomes equal to the reference voltage, the feedback circuit is stable and the gate winding current is set to a desired zero current operating point.

Abstract: A regulating shut off valve for a high pressure gas bottle useful when the pressure within the bottle can be higher than the maximum safe working pressure of a pneumatic system connected thereto. The valve is sized to fit under a standard protective cap when installed on a gas bottle. The valve includes a poppet assembly with a needle that acts with a valve seat so that the poppet assembly can be screwed open to allow gas to pass from the bottle to the system or screwed closed against the seat. The valve seat, which is operatively connected to a spring loaded piston to which system pressure is applied, is responsive to the maximum safe working pressure of the system. When such pressure is present, the valve seat moves against the needle to regulate flow.
