Publication number: 20240138764Abstract: A device is for measuring a body parameter for a subject. The device comprises a sensor for measuring the body parameter, a housing element for positioning the sensor on a body part of the subject and an actuator system within the housing element for applying a pressure to the body part. The actuator system comprises two states, a first state based on the actuator system applying a first pressure to a first area of the body part and a second state based on the actuator system applying a second pressure to a second area of the body part. The device also comprises a controller configured to apply the first and second states at different times.Type: ApplicationFiled: March 2, 2022Publication date: May 2, 2024Inventors: EDUARD GERARD MARIE PELSSERS, HANS WILLEM VAN KESTEREN, JENS MUEHLSTEFF, RALPH WILHELM CHRISTIANUS GEMMA ROSA WIJSHOFF, ANTHONIUS PETRUS GERARDUS EMANUELS JANSSEN

Publication number: 20240141886Abstract: A technique for monitoring valve and pump efficiencies for positive displacement pumps. The techniques include utilizing a data acquisition system to attain intake and discharge pressure data in combination with real-time encoder position data. Thus, when combined, output from a pump may be monitored in real-time. As a result, pump life may be extended beyond an anticipated changeout schedule. By the same token, premature pump inefficiencies may also be detected for taking a pump offline in advance of expected life. In either circumstance, multi-pump operations may be substantially enhanced with cost and time savings realized.Type: ApplicationFiled: February 24, 2022Publication date: May 2, 2024Inventors: David Gerard Gerber, Jr., Muharrem Ali Tunc, Kevin L. Case, Caroline Shipley, Han Yu, Jagan Thaduri, Seoyeon Hong
