Patent number: 5488479Abstract: The present invention is directed to a device and method for analysis of peanut pods in a machine vision system. A method of classification of the pods is based on a maturity class system wherein various colors of the pod determine its maturity and therefore its approximate harvest time. The machine vision system permits quick scanning of the entire surface area of the peanut pod to be scanned and an analysis of its maturity can then be based on the overall view of the pod. The device and process utilize the views of the peanut pod, as determined by the camera imaging system so as to compare the images with maturity classes relating to color of the pod and, therefore, a determination of ripeness and of harvestability of the peanut crop.Type: GrantFiled: December 17, 1992Date of Patent: January 30, 1996Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Earl J.

Patent number: 5331847Abstract: The present invention is drawn to soil erodibility testing utilizing: an outer backwater tank, which during testing is filled with water; an inner liner positioned at least partially within the outer backwater tank for minimizing return turbulence and providing a mount for either a feed tube or pin profiler means, and; a feed tube having a nozzle thereon, which is positioned within the interior of the inner liner. Water is forced through the feed tube and nozzle, into contact with soil to be tested, so that at least a portion of the soil is removed by erosion. The volume of soil removed by erosion is determined based on the differences between an initial soil profile and an eroded soil profile, which may be measured with a pin profiler means.Type: GrantFiled: April 16, 1993Date of Patent: July 26, 1994Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Gregory J.
