Changes in wavelength of this light caused by water vapor or oxygen absorption should help conservators monitor the gaseous environment inside the encasements, said Andrew Freedman, who helped develop the system for Aerodyne.

Prototypes for both the aerodyne and the ground-effect craft RFB X-113 ( 1970 ) then RFB X-114 ( 1977 ) were built, but no further development was undertaken.

With this system, developed by Aerodyne Research Inc . of Billerica, Mass ., light from an argon discharge lamp goes into the enclosure, reflects off the mirrors and is measured coming out.

In the 1980s, Aerodyne corporation attempted to sell an updated version of the DASH, designated the " CH-84 Pegasus ", with an Allison 250-C20F turboshaft engine and updated electronics.

The Aerodyne Jazz Bass is usually equipped with a split single-coil'p-bass'pickup at the mid position and a single-coil pickup from a Jazz Bass at the bridge position.
26.
Aerodyne Research Inc ., of Billerica, Mass ., has taken a more radical course, proposing a spheroid craft to be powered by several microturbofan jet engines firing downward from its rounded, circular bottom.
27.
A pure rocket is not usually regarded as an aerodyne, because it does not depend on the air for its lift ( and can even fly into space ); however, many aerodynamic lift vehicles have been powered or assisted by rocket motors.
28.
This version of the Aerodyne Jazz is similar to the other Japan non-export models, except that it has two ( DiMarzio-designed, but manufactured in Japan ) J-style pickups instead of a stock P / J pickup configuration.
29.
That could preclude the use of a nanotube sensor in many applications, said Charles E . Kolb, president of Aerodyne Research, of Billerica, Mass ., an instrument company that makes sensors that can detect nitrogen dioxide and ammonia in the atmosphere.
30.
Instead of using a solid state sensor, like a nanotube, to detect gases, Aerodyne's sensors use spectroscopic techniques, measuring the infrared absorption of the gases, to map the distribution of pollutants from a distance _ making measurements from an airplane or a mobile van, for example.
