ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,704,628, issued on Aug. 11, was assigned to QLM Technology Ltd (Paignton, Great Britain).

"Accurate gas leak detection using tuneable diode lidar systems" was invented by Xiao Ai (Bristol, Great Britain), James Graham Titchener (Bristol, Great Britain) and Murray Keith Reed (Paignton, Great Britain).

According to the abstract* released by the U.S. Patent & Trademark Office: "When using spectroscopic diode lidar to detect a gas of interest such as methane (CH4), detecting high concentration pathlength (CPL) values of the gas of interest may not actually indicate a plume or leak. In areas such as a refinery, where ambient gas levels may be routinely high, absorption from ambient gas me...
