Abstract: For each of a plurality of spray nozzles of an autonomous agricultural vehicle, a set of instructions provided by the autonomous agricultural vehicle to the spray nozzle is accessed. Each instruction in the set is generated by analyzing a respective image of a portion of a geographic area captured by the autonomous agricultural vehicle. A spray performance of at least one spray nozzle from among the plurality of spray nozzles is identified as an outlier by analyzing the sets of instructions respectively provided to the plurality of spray nozzles. An action with respect to the at least one spray nozzle identified as the outlier is performed. The action may be to place the vehicle in fallback state in which a targeted spray may be switched to broadcast spray.

Abstract: An agricultural material application machine includes a material reservoir that holds a material to be applied to a field, an orifice defining an opening through which material is to pass to be applied to the field, an optical sensor that captures an image of a portion of the field, and a n image processor that processes the image and identifies a target in the image. The agricultural material application machine further includes a confidence level generator that generates a confidence level based on confidence data and a controller that generates a control signal to control the agricultural material application machine based on the confidence level.

Abstract: A camera is mounted on the front of a sprayer. Targets are identified from images generated by the camera. The location of the target is identified relative to a nozzle on the sprayer. A control signal is generated to control the timing and duration of actuation of the nozzle.

Abstract: A plurality of different visual markers are deployed on a field. The markers include a target marker identifying a portion of the field that has a target of material to be applied to the field and a non-target marker identifying a portion of the field that does not have a target. An on-machine target identification system sense targets as an agricultural machine travels over the visual markers to identify targets in the field. An image processing adjustment controller correlates identified targets with the visual markers to determine an accuracy of the target identification system. An action signal is generated based upon the identified accuracy of the target identification system.

Abstract: An agricultural applicator, that applies material to an agricultural field, includes an on-board, real-time image sensor that senses targets for the material to be applied. A controller controls applicators, such as nozzles or other applicators, to apply the material to the sensed targets.

Abstract: A MEMS device and a method for making a MEMS device are described. The MEMS device includes a support member, an optical device, and a flexible member. In one aspect, the flexible member is formed separately from the support member and the optical device. In one aspect, the flexible member is dimensioned to enable flex in one direction while maintaining stiffness in two orthogonal directions. In one fabrication embodiment, the MEMS device is formed by etching an opening into the structural layer to create a structural support member and an optical device. The structural support member and optical device are mounted on a support substrate with a sacrificial layer. A flexible member is conformally deposited over the structural support member and the optical device and then etched. The sacrificial layer is partially etched away to leave the structural support member anchored to the support substrate.
