Abstract: Low profile object detection can be performed on mowers or other vehicles that may be autonomous. An autonomy controller can be employed on a mower to receive and process sensor data for a detection area to determine whether an object may be present in a region of interest within the detection area. When the autonomy controller determines that an object may be present, it can cause the ground speed of the mower to be slowed and can commence buffering region of interest sensor data over a period of time. The autonomy controller can process the buffered region of interest sensor data to determine whether an object is present in the region of interest, and if so, can alter the path of the mower appropriately.

Abstract: A method and apparatus for producing product packages comprises operating first and second feedback control loops where product package weight is averaged and used to determine one of two possible adjustments to change the product fill rate and the volume of the product. The feedback loops operate in one of a plurality of index levels. The first feedback loop seeks to improve performance by making adjustments to the fill rate and volume of the product, while incrementally moving to more stable index levels requiring tighter tolerances and package weight averages based on more product packages. The second feedback loop seeks to preserve stability by making its own adjustments to the fill rate and volume of the product if large product package weight fluctuations are sensed. The second feedback loop can move operation to less stable index levels having wider tolerances and package weight averages based on fewer product packages.
