Optical Time Distributor and Process for Optical Two-Way Time-Frequency Transfer

NIST Inventors
Laura Sinclair , Nathan R Newbury , William C. Swann and JD Deschenes
Patent Description The invention is a method to compare and synchronize "clocks" (i.e. local timescales) through optical links across free space, which include open air paths through the atmosphere to other terrestrial sites or to satellites, as well as satellite-to-satellite paths. The challenge is

Hub and Spoke System for Detecting and Locating Gas Leaks

NIST Inventors
Greg Rieker , Ian Coddington , Nathan R Newbury , Kuldeep Prasad and Anna Karion
Patent Description The current practice for detecting methane leaks is still in its infancy. There are several environmental regulations that have driven the development of Forward-looking Infrared (FLIR) cameras, thermographic cameras that senses infrared radiation, for detection of Volatile
