Abstract: A variable mechanical automotive coolant pump includes a rotatable rotor shaft, an impeller wheel which is co-rotatably connected with the rotor shaft, a static guiding cylinder, a control sleeve, and at least one guiding device. The impeller wheel has a discharging radial outside. The control sleeve has a hollow-cylindrical control sleeve body having a radial outside. The control sleeve does not rotate and is guided axially slidable within the static guiding cylinder so as to regulate a flow rate of the variable mechanical automotive coolant pump by closing or opening the discharging radial outside of the impeller wheel. The at least one guiding device guides the radial outside of the control sleeve within the static guiding cylinder.

Abstract: A sump pump system enables automatic determination and utilization of frequencies for mechanical shakers for sump pumps. These techniques may be implemented to detect a fault (e.g., a stuck impeller) with a sump pump and to identify a desirable frequency at which a mechanical shaker for the sump pump should vibrate to correct the fault.

Abstract: A sump pump system may detect and utilize motion or acceleration of water in sump basins when implementing control of sump pumps. To detect the motion or acceleration, the sump pump system may utilize a sensor that is configured to detect motion or acceleration, such as an accelerometer or gyroscope. The sump pump system may identify a water level in a sump basin based on the detected motion or acceleration, which may be compared to a reading or expected signal from the sump pump system's “typical” sensor (e.g., float switch) that is used to detect one or more water levels. In this manner, the sump pump system may detect a malfunctioning level sensor that is used by the pump to detect high-water and low-water marks at which the sump pump activates and deactivates, respectively.

Abstract: A compact, modular dosing pump system that is capable of microdose and macrodose volume flow rates, reduces or eliminates the need for additional flow control components such as temperature and pressure sensors, and utilizes a wider operational flow range than existing systems while maintaining the level of accuracy and precision exhibited by conventional dosing pump systems is provided. The dosing pump utilizes a a control system to deliver a range of fluid volumes. The control system monitors the motor emf voltage, calculates the flow rate, and makes adjustments to the pump motor voltage to precisely maintain the desired flowrate.

Abstract: A turbofan includes a circular end plate, a ring-shaped shroud facing the end plate, and a plurality of blade members disposed between the end plate and the shroud. An annular portion of a space between the end plate and the shroud where the blade members are disposed is a pressure-increase flow path. The turbofan causes air to flow from an inner peripheral side to an outer peripheral side of the pressure-increase flow path. A cross-sectional area of the pressure-increase flow path increases gradually from an upstream end toward a downstream end of the pressure-increase flow path.

Abstract: Apparatus and methods are described including a left ventricular assist device. The left ventricular assist device includes an impeller configured to be placed inside a subject's left ventricle, and to pump blood from the subject's left ventricle to the subject's aorta, by rotating. A frame is disposed around the impeller. A tube traverses the subject's aortic valve, such that a proximal portion of the tube is disposed within the subject's aorta and a distal portion of the tube is disposed within the subject's left ventricle. The distal portion of the tube defines one or more blood inlet openings that are configured to allow blood to flow from the subject's left ventricle into the tube. A mesh is configured to prevent inner structures of the left ventricle from passing into the one or more blood inlet openings. Other applications are also described.

Abstract: The present disclosure relates to a system, an apparatus, and a method for managing health condition of at least one rotating system. The method includes receiving, by a processing unit, operational data associated with the rotating system in real-time, from one or more sensing units. The operational data includes parameter values corresponding to an operation of the rotating system. Further, a virtual replica of the rotating system is configured using the operational data. A behavior of the rotating system is simulated on a simulation instance of the rotating system based on the configured virtual replica. The simulation results are analyzed to determine an abnormality in the health condition of the rotating system. The abnormality corresponds to a health status of an internal component of the rotating system. Further, a notification indicating the abnormality is generated, on a Graphical User Interface.

Abstract: A method for operating a pump includes establishing a pump limit characteristics diagram by mapping a first system parameter (P1) as a function of a second system parameter (P2) to identify a permissible operating region of the pump; for each first system parameter value (P10), identifying a minimum allowable second system parameter value (P20); monitoring the first system parameter (P1) and identifying a minimum allowable second system parameter value (P20) corresponding to the monitored first system parameter value (P1m); monitoring the second system parameter (P2) and comparing the monitored second system parameter value (P2m) with the identified minimum allowable second system parameter value (P20); and regulating a control valve that controls fluid flow through a return line connecting the suction and discharge sides of the pump so that the monitored second system parameter value (P2m) does not fall below the minimum allowable second system parameter value (P20).
