Abstract: Technologies for guiding an agricultural vehicle through crop rows using a camera and signal processing to locate the crop row or centers of the crop row. The signal processing uses a filter to filter data from images captured by the camera and locates the row or the centers based on the filtered data. The filter is generated based on a signal processing transform and an initial image of the crop row captured by the camera. The filter is applied to subsequent images of the crop row captured by the camera. In some embodiments, the camera includes one lens. For example, monocular computer vision is used in some embodiments. Also, in some embodiments, a central processing unit generates the filter based on the transform and the initial image of the crop row and applies the generated filter to the subsequent images of the row.

Abstract: This disclosure includes safety valves, vehicles and fueling stations having the same, and related methods. Some safety valves have a valve body defining a fluidic network including an inlet and an outlet, a piston disposed within and movable relative to the valve body between a first position in which the inlet is in fluid communication with the outlet and a second position in which fluid communication between the inlet and the outlet is prevented, and a heat-defeatable barrier that prevents movement of the piston to the second position. In some safety valves, the piston is biased toward the second position. In some safety valves, the piston includes a channel disposed between first and second ends of the piston, and when the piston is in the first position, the inlet is in fluid communication with the outlet via the channel.

A method of applying an herbicide to an agricultural field includes measuring a total vegetation density in the agricultural field and spraying a variable amount of an herbicide through at least one nozzle onto the agricultural field. The amount of herbicide is based on the measured total vegetation density, without regard to distinction between crop and weed.

Abstract: A gas cup for a damper assembly comprises a body including an upper surface, a lower surface, an exterior surface and an interior surface. The body defines an aperture extending through the upper surface and the lower surface. A decoupler is located in the aperture and secured to the body. A bridging member is located between the decoupler and the body and coupled to the decoupler and the body. The decoupler and the bridging member is made from materials having different elasticity to allow the decoupler to move in the aperture in response to a volumetric change in the damper assembly and to provide variable tuning of the damper assembly. A damper assembly including the gas cup is also disclosed herein.

Abstract: An agricultural applicator machine has a frame and at least one horizontally extending boom assembly. The boom assembly pivots to a folded position in which it is secured in a boom-cradle mechanism. The boom-cradle mechanism includes a crossmember and a boom rest at an outer end of the crossmember, the boom rest having a rigid inboard boom stop, a rigid outboard boom stop, and a saddle portion. The inboard boom stop extends from the saddle portion in an out-of-phase configuration relative the outboard boom stop. The boom-cradle mechanism has a locking assembly having an actuator assembly configured to rotate the crossmember, and thus the cradle boom rest. The actuator assembly connects to the crossmember through a linkage assembly. The actuator assembly causes the crossmember to rotate causing the boom rest to move between an open position and a locked position.
