Patent number: 11759185Abstract: A method for collecting and analyzing urine at the time it is released uses a urine collecting tube joined with a canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection with the urine tube.Type: GrantFiled: January 27, 2022Date of Patent: September 19, 2023Assignee: Ur24Technology, Inc.Inventor: Landon Duval

Patent number: 11733139Abstract: Sag propensity of a fluid can be determined by applying an oscillatory strain at an amplitude in excess of a linear region and below a yield strain of the drilling fluid. This may include use of medium amplitude oscillatory shear (MAOS), from which an elastic modulus of the fluid is determined. The elastic modulus may be determined over time, from which a time to reach maximum elastic modulus can be determined. The time to reach maximum elastic modulus is then converted or correlated to a drilling fluid sag propensity for the drilling fluid either in absolute terms or in relation to base or comparison fluids. Such an evaluation can be performed using a torsional resonance device in which the oscillatory strain is controllable so as to be maintained relatively constant during the measurement.Type: GrantFiled: May 25, 2022Date of Patent: August 22, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Andrew Clarke
