The issue of high-speed optimal-positioning for piezo-based systems is studied in this paper. The positioning bandwidth of piezo-based systems is limited by the lowest structural vibrational frequency of the system, because structural vibrations cause significant positioning errors (Pohl, 1986).

Automating Assembly of Varex’s Shield Can – The manufacturing process of Varex’s X-Ray Tube Shield Can is currently done manually. Manual assembly takes up a large portion of the technician’s day, for this reason, Varex has sponsored us to automate the process in order to allow the technician to tend to more important matters throughout the day.
Sliding Contact: Linear Motion Sliding contact linear bearing systems are comprised of a moving structure, often referred to as the carriage or slide, and the bearing elements and the surfaces on which they slide are called the rails, ways, or guides. It is more complex to make the inner surface of the carriage match the outer surface
