The Nanopump, an insulin-delivery pump, uses MEMS (Micro-Electro-Mechanical System) technology to allow a tiny pump to be mounted on a disposable skin patch. Insulin pump therapy, officially called Continuous Subcutaneous Insulin Infusion, provides continuous insulin infusion. That’s considered an attractive alternative to individual insulin injections that must be administered several times a day. The MEMS device from Debiotech S.A. of Lausanne, Switzerland, which can be worn as a patch on the skin, uses chips produced by STMicroelectronics. The pump, which will ship next year, is about one quarter the size of pager-sized currently available insulin pumps.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
