Publication number: 20240035992Abstract: A magnetic resonance device for monitoring growth of tissue in one or more bioreactors. The device can include a first magnet and a second magnet that can form a uniform magnetic field of desired strength around at least one sample of effluent from at least one bioreactor. At the command of a controller, an RF signal can illuminate the at least one magnetized sample, and sensors can detect at least one echo signal from the at least one magnetized sample. The controller can characterize the at least one sample based on the at least one echo signal. A resonator can shape the at least one echo signal.Type: ApplicationFiled: October 12, 2023Publication date: February 1, 2024Inventors: David Blumberg, JR., Michael C. Tilley, Derek G. Kane, David C. Nivens

Publication number: 20230355951Abstract: A pump for treating a patient is disclosed that includes a spring-biased plunger biased toward actuation against a tube; a cam shaft configured to actuate the spring-based plunger; a lever actuatable between a closed position and an open position; a shaft coupled to the lever, the shaft having a central axis centrally along the length of the shaft, the shaft coupled to the lever to rotate around the central axis in accordance with actuation of the lever; and a lift cam pivotally coupled to the shaft, wherein the lift cam pivots around a lift cam axis, the lift cam axis of the lift cam is parallel to the central axis of the shaft, and the lift cam engages with the spring-based plunger to lift the spring-biased plunger off of the cam shaft as the shaft rotates in accordance with actuating the lever to the open position.Type: ApplicationFiled: July 21, 2023Publication date: November 9, 2023Inventors: Michael J. Baier, David Blumberg, JR., Hugh J. Boddington, Thomas A. Friedrich, Paul G. Girouard, Larry B. Gray, David C. Nivens
