Briefs : Test & Measurement
Ionization-Based Multidirectional Flow Sensor

One significant area of research in fuel cell technology includes systems in which a fuel cell is combined with another power generation device (a turbine, for example) to create a hybrid system that combines the advantages of the two standalone systems, resulting in a high fuel-to-electricity...

Briefs : Test & Measurement
Real-Time Ion Mobility Sensor System

A real-time ion mobility sensor developed to detect contaminants and explosives is reliable, sensitive, robust, and inexpensive. The technology improves sensitivity and reduces false alarms for threat agents, and can identify chemicals with a sensitivity of five parts per billion.

Briefs : Test & Measurement
Optimetric Measurements Over Coherent Free-Space Optical Communication

High-precision ranging (optimetric) instruments are highly desired for both space navigation and communications as well as gravitational-based science missions. Traditionally, these measurements are made with instruments solely dedicated to ranging (i.e. Doppler shift of a...

Briefs : Test & Measurement
Gated Chopper Integrator (GCI)

Microvolt-level signals require gains of at least a thousand. Offsets and noise in the amplifier chain will be amplified by the same amount, which can saturate the amplifier or swamp the signal so it is not resolvable. Other methods use chopping and/or autozero techniques to lower the offset and noise. The key...
