ABOUT THE AUTHOR Robert L.Norton earned undergraduate degrees in both mechanical engineering and in- dustrial technology at Northeastern University and an MS in engineering design at Tufts University.He is a registered professional engineer in Massachusetts and New Hamp- shire.He has extensive industrial experience in engineering design and manufacturing and many years experience teaching mechanical engineering,engineering design,com- puter science,and related subjects at Northeastern University,Tufts University,and Worcester Polytechnic Institute.At Polaroid Corporation for ten years,he designed cam- eras,related mechanisms,and high-speed automated machinery.He spent three years at Jet Spray Cooler Inc.,Waltham,Mass.,designing food-handling machinery and prod- ucts.For five years he helped develop artificial-heart and noninvasive assisted-circula- tion (counterpulsation)devices at the Tufts New England Medical Center and Boston City Hospital.Since leaving industry to join academia,he has continued as an indepen- dent consultant on engineering projects ranging from disposable medical products to high-speed production machinery.He holds 13 U.S.patents. Norton has been on the faculty of Worcester Polytechnic Institute since 1981 and is currently professor of mechanical engineering and head of the design group in that de- partment.He teaches undergraduate and graduate courses in mechanical engineering with emphasis on design,kinematics,and dynamics of machinery.He is the author of numerous technical papers and journal articles covering kinematics,dynamics of machin- ery,carn design and manufacturing,computers in education,and engineering education and of the text Machine Design:An Integrated Approach.He is a Fellow of the Ameri- can Society of Mechanical Engineers and a member of the Society of Automotive Engi- neers.Rumors about the transplantation of a Pentium microprocessor into his brain are decidedly untrue (though he could use some additional RAM).As for the unobtainium* ring,well,that's another story.
