Non-Destructive Concrete Quality Testing System

NIST Inventors
Huaiyu Heather Chen-Mayer
This invention uses prompt gamma neutron activation analysis (PGAA) to analyze materials, especially concrete, without damaging them. It fires neutrons at the sample, which then emits gamma rays. By measuring those rays, the material's makeup can be identified, including cement, sand, aggregates
The photo shows the entire ENTR_v2 measurement setup that was recently deployed for field testing to Nellis Air Force Base. ENTR_v2 along with electronics and a laptop for controlling the system are depicted. A commercial red colored torque screwdriver is shown as an example of a tool which can be calibrated by ENTR.

Electronic Torque Realization Apparatus

NIST Inventors
Stephan Schlamminger and Leon Chao
ENTR (Electronic NIST Torque Realizer) is a table-top-sized device designed for generating and measuring torques.
A hypothetical concept rendering of the self-calibrating optomechanical photonic thermometer chip resting on a laboratory workbench.

Self-Calibrating Micro-Thermometer Combining Light and Mechanical Motion

NIST Inventors
Daniel Barker , Nikolai Klimov and Thomas Purdy
This invention is a tiny, high-tech thermometer system built on a single microchip. It uniquely combines two different types of light-based sensors: a photonic thermometer and an optomechanical thermometer. The photonic thermometer is used to take quick and highly precise temperature readings
