Integration of an edge extraction cellular automaton
A compact optical coprocessor dedicated to the edge extraction on binary images is presented. Four cellular automata using optical interconnections implementing an OR logical function and optical photothyristors acting as inverting and noninverting optical gates are proposed. This machine could reasonably process 1024 X 1024 images with present technologies.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.

The study put forward and designed a mechanical harvest scheme for Rhizoma corydalis according to planting mode in Hanzhong of Shaanxi Province.The machine used fixed groove type digging shovel,single mandatory shaking screen and "Z" screen separation.Its motive power used agricultural small tractors.The machine harvester weight 80 kg and harvest width to one meter.It can completely realize excavation,separation and screening in one procedure.Its structure is simple,easy to use,saving energy and high recovery ratio.The machine have widely application prospect.
