Task-dependent scheduling of feedback gains in animal motorsystems: too much, too soon for FES control?

Summary form only given. The idea that certain parts of the mammalian nervous system, such as the cerebellum, might be specialized for setting transmission parameters elsewhere is discussed. Experiences with the control of electrical stimulation in paretic patients, experiences which have shown that transducer systems are still far too primitive to allow this level of sophistication, even in laboratory-bound devices, are described. At best controllers rely on fixed-parameter feedback from one or two sensors to cycle through a simple finite-state control sequence. Kinematic variables are essentially driven open-loop. The author's approach to functional electrical stimulation (FES) control is constrained by transducer technology, and evolves virtually without reference to the features of the animal control systems described     

All this and engineering too: a history of accreditation requirements

This article traces the history of US engineering accreditation with regard to non-technical curriculum requirements from the founding of the Engineers' Council for Professional Development (ECPD) in 1932 up to the adoption of Engineering Criteria 2000 (EC 2000) in 1999. The activities of the ECPD, which became the Accreditation Board for Engineering and Technology, ABET, in 1980, took place in the larger context of the development of engineering as a profession and steps that industrial and academic leaders took during the 20th century to increase the quality and uniformity of engineering education. The story is not a simple, straightforward tale of how a homogeneous pro-business cadre of engineering educators designed a system of education for purely pragmatic ends. Buried in the volumes of old journals and annual reports is evidence that engineering educators and leaders indulged in a serious amount of organized introspection over the years.

Patents: the inventor who claimed too much

How much right should an inventor have to control the future? That was the question decided by the United States Supreme Court in the famous 1853 case of Samuel Morse and his telegraph, and the answer the Court gave then is still the law today. This rule of law, now more than 140 years old, says that no matter how great an invention may be, there comes a point where a court will step in and say that the public's right supersedes the inventor's right. Fortunately for Morse, he was able to stop O'Reilly's infringement based on his narrower claims. Similarly, inventors seeking broad patent protection today include narrower claims in their patents to protect against the possibility that a court may find that they, too, have claimed too much     

Never too early to save for the future

One of the toughest parts of being a grad student is having a limited income. Paying for groceries can be a challenge, never mind finding the money to pay for even a limited education in finances. Grogan Advisory Services, which bills itself as an independent financial services firm, works with the IEEE to offer free advice to student members of the IEEE. A review of current assets and how those assets can be invested to possibly increase their return is among those free services. Larry Grogan, who is the company's head, said that a number of free services are available to all members of the IEEE. Those free services include a portfolio review and consultation and Webinars, which are Web-based seminars that focus on financial topics such as retirement. Individual financial plans can also address investment analysis, funding education, evaluating stock options, and charitable giving, among other topics.
