ALEXANDRIA, Va., Nov. 3 -- United States Patent no. 12,782,181, issued on Nov. 3, was assigned to REMONI A/S (Skanderborg, Denmark).

"Ultrasonic flow sensor and thermal energy sensor with non-invasive identification of no-flow and improved accuracy" was invented by Bo Eskerod Madsen (Ostbirk, Denmark).

According to the abstract* released by the U.S. Patent & Trademark Office: "An ultrasonic flow sensor is configured to determine the time-of-flight of ultrasonic waves and calculate a change in the speed of sound on the basis of the time-of-flight, to calculate the expected change in speed of sound as a function of the detected temperature of the fluid, to determine if the expected change in speed of sound corresponds to the change in the s...
