Circulation, 1998 Probably no move by the federal government in recent years has generated more alarm than the so-called PATH audits in teaching hospitals. Late last year, more than 40 named teaching hospitals, institutions, and organizations filed suit to halt the audits, calling them retroactive enforcement and a threat to the future of medical education. On April 27,

Active Sticks: a New Dimension in Controller Design [PDF]
, 1984 A smart stick controller was built which actively produces a force to interact with the subject's hand and to aid in tracking. When the human tracks in this situation, the man-machine system can be viewed as the combination of two closed loop feedback ...
