The DSPH Series of 12- to 16-bit, 25 VA, reference-powered digital-to-synchro converters require a (plusMinus)5V dc input power and have internal transformer-isolated outputs even at 60 Hz. The series will accept up to 16-bit natural binary input and convert it to 90V 3-wire synchro signal from 60 to 400 Hz with an accuracy of up to (plusMinus)2 minutes of arc. The output is short-circuit-proof and current-limited with transient protection and thermal cutoff. A kick circuit frees the torque receiver rotor to prevent hangups. The unit is packaged in a 5.09 x 7.4 x 2.60-inch bulkhead-mounting metal case.

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.
