Lured by low pump prices, U.S. motorists care less about fuel efficiency
2015-12-04 22:33:44| Auto Dealers - Topix.net
The average fuel economy of new cars sold in the U.S. in November dropped by 0.1 mile per gallon, continuing a trend that began in August of last year when pump prices began to fall, according to new data by the University of Michigan Transportation Research Institute. New cars sold in November got an average of 25 miles per gallon , down 0.8 from the peak reached in August of 2014, but still up from 4.9 mpg since October of 2007, when the university began tracking sales.

Fused Dual Clad Fiber Couplers deliver high efficiency.
2015-12-03 14:31:08| Industrial Newsroom - All News for Today
Typical 2X2 Fused Dual Clad Fiber (FDCF) couplers have Dual-Clad (DC) fiber in 2 opposite leads and multimode (MM) fiber in other 2 arms. DC input fiber can be optionally replaced with matching single-mode (SM) fiber, and MM output fiber can be terminated to form 2x1 FDCF coupler. Manufacturing process offers broad wavelength range and 100% transmission for SM fiber input. Applications include OCT and super resolution imaging, fiber sensors, spectroscopy, and confocal/fluorescence microscopy.
