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

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.

Interferometric Microphone Calibrator And Comparison Calibrating A Microphone

NIST Inventors

Richard A. Allen and Randall P Wagner

A precision laser-based comparison calibration method for laboratory standard microphones that uses reference microphones calibrated by the pressure reciprocity method.

Monitoring Ultraviolet Radiation Bioremediation

NIST Inventors

Yaw S. Obeng

Advances in UV-antimicrobial metrology focused on underpinning the development of standards.

Rydberg Atom Mixer and Determining Phase of Modulated Carrier Radiation

NIST Inventors

Josh Gordon , Christopher L. Holloway and Matt Simons

Rydberg atoms have been shown to be very useful in performing absolute measurements of the magnitude of a radio frequency (RF) field using electromagnetically induced transparency (EIT). However, until this invention, there has been less success in using Rydberg atoms for the measurement of the

Electron Reflectometer and Process for Performing Shape Metrology

NIST Inventors

Wen-Li Wu

An electron reflectometer includes: a sample stage; a source that produces source electrons; a source collimator; and an electron detector that receives collimated reflected electrons.

Inertial Measurement Unit and Diagnostic System

NIST Inventors

Gregory W. Vogl

An inertial measurement unit determines performance degradation of a linear axis and includes: an accelerometer that, when disposed on a motion member of the linear axis including the motion member and a base member: measures acceleration of the motion member; and provides a displacement of the

Non-contact Measuring Tool for Precision Measurement

NIST Inventors

Josh Gordon

This invention introduces a non-contact measuring tool designed for precise measurement of objects without physically touching them. It uses advanced optical and sensor technologies to capture accurate data on an object's dimensions and surface characteristics. The tool enhances measurement
