Prepared patent application covering improved methods of maintaining vehicle formations in autonomous “follow me” applications. For some applications, maintaining a specified formation may be most important, while in other applications, following at a safe speed and distance may be most important. Described methods use positioning and route planning techniques to provide specified formations while ensuring safe operation.

Prepared patent application covering improved plant detection techniques that can be used to reduce the amount of herbicide needed to eradicate weeds in a field. Applying herbicide only to plants rather than plants and bare ground can significantly reduce costs. Described methods adjust intensity of emitted light beams to optimize plant detection sensitivity. (US 10,656,133)

Prepared patent application covering improved techniques for estimating yield of crops that are placed in windrows during harvesting. Yield estimation during harvesting can be helpful in preparing yield maps that can be used to identify trends across a plot. The described methods estimate volumes based on profiles of the windrows and use positioning techniques to provide the mapping. (US 2020/0141784)

Prepared patent application covering improved techniques for autopilot steering compensation. Autopilot guided farm vehicles improve operation efficiency. Described methods use sensors to identify various conditions and provide real-time adjustments. (US 9,788,659)
