Li-ion Cell Calorimeter
Lithium-ion batteries are an integral part of energy storage systems used in NASA's Exploration program, as well as many modern terrestrial industries. NASA Johnson wanted a better way to measure total and fractional heat response of specific types of Li-ion cells when driven into a thermal runaway condition.

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...

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...
