ALEXANDRIA, Va., April 15 -- United States Patent no. 12,601,680, issued on April 14, was assigned to Radiometer Medical ApS (Bronshoj, Denmark).

"Method of and a system for determining a parameter of a fluid" was invented by Thomas Kjaer (Bronshoj, Denmark).

According to the abstract* released by the U.S. Patent & Trademark Office: "A system (10) for determining a refractive index of a sample fluid or a concentration of a component in the sample fluid comprises a transparent sensing element (12) with a plurality of pores (122) for receiving a fluid. The pores reflect or scatter radiation emitted by a radiation emitter (14) of the system differently depending on the refractive index of the fluid. The system comprises one or more detectors...
