Demonstration of signal collected on a single detector of coincident detection of particles in two regions. Recovery of the components of the signal from each particle is demonstrated through signal demodulation.

Multiplexed Amplitude Modulation Photometer And Performing Multiplexed Amplitude Modulation Photometry

NIST Inventors

Anthony J. Kearsley , Gregory A Cooksey and Paul Patrone

The invention - a multiplexed amplitude modulation fluorometry, is a method of signal generation, acquisition, and analysis that can simultaneously detect and distinguish fluorophores contained on or in many distinct samples separated in space and/or wavelength.

Schematics of photonic AC-DC converter. Color represents surface temperature of the device upon applying DC voltage to the electrode.

Smart Energy Converter for Efficient Power Use

NIST Inventors

Nikolai Klimov , Stefan Cular and Joseph Hagmann

This invention introduces a photonic-based AC-DC equivalence converter that operates using temperature-controlled photonic chips. It leverages isothermal regions to regulate voltage and improve energy efficiency. The technology enables precise energy conversion with minimal loss. By utilizing

Smart Fire Hose Flow Monitoring System

NIST Inventors

Gregory W. Vogl and Wai Cheong Tam

This invention introduces a wireless sensor network to measure water flow rate in fire hoses, enhancing firefighting efficiency. It uses piezoelectric accelerometers attached externally to detect vibrations caused by flowing water. These signals are wirelessly transmitted to a base station, where

A Smarter Way to Separate and Analyze Substances

NIST Inventors

Wyatt N. Vreeland

This invention introduces a method and device for affinity gradient focusing, which directs analytes in a solution containing a pseudo-stationary phase within a channel, such as a capillary or microchannel. It establishes a steady-state spatial gradient in the retention factor of the pseudo
