  • Publication number: 20240091422
    Abstract: 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.

  • Patent number: 5998944
    Abstract: An apparatus and method for controlling a lifting magnet (12) of a materials handling machine (10) to eliminate arcing between contacts (70-80) within the magnet controller (26) as is well as is large voltage spikes. The controller (26) selectively excites the shunt field windings (66,68) of a direct current generator (22). The magnitude and direction of the current passing through the shunt field windings (66,68) is varied by the magnet controller (26) to control the magnitude and polarity of the voltage at the generator output (23). The armature (60) of the generator (22) is rotatably driven by a hydraulic motor at an essentially constant speed to minimize voltage variations at the output (23) of the generator (22). At least the drop cycle is controlled through use of a current transducer (200) that senses current flowing to the lifting magnet so that the electronic controller is able to control the flow of current to the lifting magnet based upon the sensed current in the magnet circuit.

  • Patent number: 5977730
    Abstract: A hydraulic circuit (124) is defined in a manifold (130) which may be aluminum, steel, or any other suitable material. The circuit (124) regulates the flow of hydraulic fluid to the hydraulic motor (120) and thus ensures that the motor rotates at an essentially constant speed, independent of the speed of the hydraulic pump (122) supplying the circuit. The circuit includes a pressure compensated flow control valve assembly (140) with an adjustable flow control valve (142) that regulates the flow of hydraulic fluid to the motor (120). The assembly (140) also includes a balanced piston-type pressure compensator (144) that ensures a select pressure differential across the flow control valve (142) such that the flow through the valve (142) remains at least essentially constant. This constant flow through the pressure compensated flow control valve assembly (140) ensures an essentially constant rotational speed of the motor (120).

The magnet controller (26) includes a programmable logic controller (40) which selectively opens and closes the contactors (70-80) within the controller (26).

  • Patent number: H1910
    Abstract: A wheeled carrier adaptable for use with material handling equipment comprises a main body and first and second frames adjustably connected to the main body portion. Wheel assemblies are connected to the frames. The width of the carrier is adjustable so the carrier can be easily transported yet provide sufficient stability when used in material handling applications.
