Demystifying Optical Ethernet Networks

The TDM-to-packet network transformation has been underway in transport/ telecommunications networks for some years now, fueled primarily by two trends: (a) the advent of triple-play (voice, video, data) for enterprise and residential customers and, lately, the explosion in video and mobile data services, and (b) the evolution in both packet- and transport-network equipment.

Spectrometer Helps NASA Detect Water in Excavated Moon Matter

QE65000 Spectrometer
Ocean Optics
Dunedin, FL

An Ocean Optics QE65000 spectrometer has contributed measurements to the Lunar Crater Observation and Sensing Satellite (LCROSS) mission, helping NASA scientists to officially confirm the presence of water on the Moon. The spectrometer, dubbed ALICE, was custom re-engineered by Aurora Design & Technology to withstand the extreme temperature, radiation, shock, and vibration of space.

Connector Improves Reliability, Cuts Cost on Engine Production Line

HARTING North America was recently asked to solve some of the problems associated with power distribution and motion control on a vehicle manufacturer’s long conveyor and engine block production line. The line’s system integrator needed to reduce installation costs to be competitive with other potential suppliers, and the end customer was looking for higher reliability and ease of maintenance.

NASA Drops Chopper to Test New Technology

How do you make a helicopter safer to fly? You crash one. NASA aeronautics researchers at Langley Research Center in Hampton, VA, recently dropped a small helicopter from a height of 35 feet to see whether an expandable honeycomb cushion called a deployable energy absorber could lessen the destructive force of a crash. On impact, the helicopter’s skid landing gear bent outward, but the cushion attached to its belly kept the rotorcraft’s bottom from touching the ground. Researchers must analyze the test results before they can say for sure whether the deployable energy absorber worked as designed.
