Title: A method for determining the degree of cure in forages
Inventor: KELLY RICHARD
IPC: G01R33/50
Filed: 2019-04-18
Abstract: A method for determining the degree of cure in forages using a nuclear magnetic resonance (NMR) technique. An NMR instrument is used to determine the amount of bound moisture (typically called stem moisture) and free moisture (typically called dew moisture) the degree of which can be used to determine how cured the forage is. This method represents an improvement on the traditional ways of determining how cured a forage is. The traditional ways have been by twisting a bunch of forage in ones hands or using a mechanical method (Hammer of fingernail) to determine if there is too much stem moisture in the stem nodes. The method can be applied using a portable instrument or building the instrument into a forage harvesting machine such as a hay baler.

Abstract: Provided is a method and apparatus for combining perceived depths to construct a floor plan using cameras, such as depth cameras. The camera(s) perceive depths from the camera(s) to objects within a first field of view. The camera(s) is rotated to observe a second field of view partly overlapping the first field of view. The camera(s) perceives depths from the camera(s) to objects within the second field of view. The depths from the first and second fields of view are compared to find the area of overlap between the two fields of view. The depths from the two fields of view are then merged at the area of overlap to create a segment of a floor plan. The method is repeated wherein depths are perceived within consecutively overlapping fields of view and are combined to construct a floor plan of the environment as the camera is rotated.
