Publication number: 20240091422Abstract: A renal therapy system is disclosed. In an example, the renal therapy system includes a home renal therapy machine that stores, to a log file, dates of when renal therapies were performed and a type of each renal therapy that was performed. The system also includes a server that receives the log file from the home renal therapy machine. The server compares the dates and types of performed renal therapies stored in the log file to a device program that specifies dates for performing renal therapies and the types of renal therapies to be performed. The server displays a flag in a user interface of a clinician computer when there is a deviation from the comparison.Type: ApplicationFiled: November 20, 2023Publication date: March 21, 2024Inventors: Neil Tiwari, Joshua James Miller, Marc Steven Minkus, Matthew R.

Publication number: 20220105611Abstract: A power tool and method of determining torque is provided. The method of determining torque uses the energy output by the drive mechanism and the angle of rotation of the output shaft to estimate torque.

Patent number: 6196332Abstract: A rotational energy storage device or spring which includes a roller-cam assembly having a shaft, a ring rotatably disposed about the shaft, and at least one roller disposed between shaft and ring. The roller is configured such that, upon rotating the ring relative to the shaft, the roller interferes with the ring and the shaft to convert and effect storage of mechanical energy created by the relative rotation of the ring and the shaft. Preferably a plurality of spaced rollers are positioned between ring and shaft. A cam geometry which is symmetrical or asymmetrical is provided on the shaft, the ring, the roller, and combinations thereof. A rotational energy storage device having a back-up ring with alternating thin and thick cross-sectional areas is further provided which is indexed to provide regions of low and high stiffness regions against each roller.Type: GrantFiled: December 3, 1998Date of Patent: March 6, 2001Assignee: Ingersoll-Rand CompanyInventors: Gregory P.
