Photoacoustic Soot Measurement System for Cleaner Engines

NIST Inventors

Amy Mensch , Ryan Falkenstein-Smith and Thomas Cleary

This invention introduces a photoacoustic measurement system that detects soot deposition in engines. It works by irradiating soot deposits with pulsed electromagnetic radiation, causing rapid expansion that generates an acoustic pressure wave. The system then senses the pressure wave using an

Smart System for Organizing and Verifying Engineering Certificates

This invention introduces a system and method for managing engineering certificates. It streamlines the process of handling, verifying, and storing certificates digitally. The system ensures secure access and efficient retrieval of engineering credentials. It reduces paperwork and enhances

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

A Super Accurate Temperature Sensor That Works Without Electricity

NIST Inventors

Nikolai Klimov , Tobias Herman and Zeeshan Ahmed

This invention introduces a photonic thermometer that uses optical fibers to measure temperature. The thermometer is designed with a sheath and module assembly to enhance accuracy and durability. It leverages photonic technology to provide precise temperature readings without relying on traditional

Next-Gen Laser Radar (LIDAR) for High-Accuracy Applications

NIST Inventors

Ian Coddington and William C. Swann

This invention is a new kind of laser radar (LIDAR) that uses two special lasers called femtosecond fiber lasers. One laser sends out a signal, and the other helps detect the signal that bounces back from a target. It combines two types of measurements—time-of-flight and interferometry—to measure
