Medical electronics

Article Abstract:

Advances in medical electronics in 1992 are highlighted by the new implantable defibrillators for people at risk of developing life-threatening heart rhythms. The implants deliver electric shocks to restore an abnormally beating heart to normal beating and are comprised of a pulse generator and electronic circuitry with insulated flexible wires that connect the pulse generator to the heart. The present devices are about the size of a bar of soap and also incorporate a pacemaker; future versions are expected to be much smaller. Use of opthamalic lasers to correct vision by reshaping the eye was in the final research stages in 1992. Excimer sculpting is considered an improvement over radial keratotomy because only ten to 15 percent of the corneal thickness is pared away with this newer method. The US Federal Food and Drug Administration delays in approving new medical products for the $35 billion-per-year industry.

The keys to innovation: research, education, and entrepreneurship

Article Abstract:

The keys to innovation may be said to be research, education, and entrepreneurship, factors that form a natural combination. At Hope College (Holland, MI) getting students and faculty into collaborative research is a major goal. Projects in the chemistry department involving understanding the nature of energetic molecules, reactivity, and excitation and using new technology, lasers and spreadsheets, are discussed. Students learn the principles of quantum mechanics. The Internet is used to encourage learning using interactive documents, which let students experience and interact with ideas. DiscusWare is a company formed by students and a faculty member to market/distribute software developed to share ideas and discuss coursework electronically. WebMO, a Web product for computational chemistry has been developed.

Laser speeds digitising of finest details

Article Abstract:

A research project by the UK universities of Nottingham Trent, Salford and Surrey is developing a 3D laser scanning system for production environments. The new visual inspection system is accurate to 2.5 microns and is able to examine 650,000 points a second. The Automatic Solder Paste Monitoring, Inspection and Control (ASPMIC) system is 40 times swifter than conventional techniques and its technology has implications for other CAD input digitising and 3D scanning processes.
