On Wednesday afternoon, April 29, 19 student teams from the Mechanical and Industrial Engineering (MIE) Department and College of Nursing will demonstrate their brilliant, useful, and humanitarian inventions. Their fascinating innovations include a new and improved walker for a patient suffering from debilitating rheumatoid arthritis, a more efficient and economic device for farmers to remove seeds from squash, an ergonomically correct apparatus for pulling beer kegs off storage racks in a warehouse, and a dynamometer to help rehabbing patients assess the proper positioning of their damaged knees.
