A method includes obtaining a set of pressure measurements at an electronic pump and storing the set of pressure measurements in a memory storage, where each measurement time of the set of pressure measurements is within a measurement duration. The method includes determining and sending a measure of central tendency to a second computing device via a first wireless signal. The method also includes determining a subset of pressure measurements based on the set of pressure measurements. The method includes transferring the first subset of pressure measurements to a data collection device via a second wireless signal, wherein an operating frequency of the second wireless signal is greater than one gigahertz and deleting the first subset of measurements from the memory storage.

A method and controller for controlling electrical activation of elements in a system. A method includes identifying (710) a first element (102) of a system (100) by a control system (600), among a plurality of elements (102, 110, 122) of the system (100), that is to be powered. The method includes determining (712) connected elements (110, 122) of the system (100) by the control system (600). The connected elements (110, 122) are connected to deliver power to the first element (102) directly or indirectly, based on an adjacency matrix (400), and the adjacency matrix (400) identifies connections between each of plurality of elements of the system (100). The method includes identifying (714) at least one of the connected elements (110, 122) to activate by the control system (600), based on the adjacency matrix (400), a health table (500), and the connected elements (110, 122), to deliver power to the first element (102). The method includes activating (716) the at least one of the connected elements (110, 122) by the control system (600), thereby delivering power to the first element (102).

A variable geometry turbocharger according to an embodiment includes a rotational shaft; a turbine wheel disposed on one end side of the rotational shaft; a compressor wheel disposed on another end side of the rotational shaft; a bearing housing for housing a bearing part for rotatably supporting the rotational shaft; a variable nozzle structure for controlling a flow rate of an exhaust gas flowing into the turbine wheel, the variable nozzle structure including a nozzle plate and nozzle mount that define an exhaust gas flow passage for allowing the exhaust gas to flow into the turbine wheel, a nozzle vane disposed rotatably about a support shaft in the exhaust gas flow passage, and a drive part for rotating the nozzle vane, the drive part being disposed in an internal space defined between the bearing housing and the nozzle mount; and a cooling gas passage for extracting compressed gas compressed by the compressor wheel and introducing the compressed gas into the internal space.

A method serves for operating an electronically controlled pump assembly (1), with which setting parameters of the pump (2) can be adjusted in an electronic control (6), for adaptation to the hydraulic demands of the location installation situation (4, 5). Operating data is registered during the operation of the pump assembly (1). After a predefined time and on the basis of the registered operating data, it is examined as to whether the pump assembly (1) has been set vis-à-vis the factory settings. If this is not the case a signal (11) is issued in order to point out the necessary setting.

A pump assembly is disclosed comprising, a pump including a pump housing having a fluid inlet. At least one fluid outlet extends from the pump housing. An impeller driven by a motor is mounted in the pump housing arranged to move a fluid from the fluid inlet to the at least one fluid outlet. A valve rotatably mounted between the impeller and the at least one fluid outlet selectively controls the flow of fluid through the at least one fluid outlet.

The present disclosure relates to a motor for an extracorporeal blood pump, an extracorporeal blood pump, and an extracorporeal blood pump system. The motor for an extracorporeal blood pump comprises: a housing; an actuator located in the housing and used for driving an impeller in a pump head of the extracorporeal blood pump; at least one sensor located in the housing; and a motor driving-control assembly located in the housing and used to control operation of the motor. Integrating the motor driving-control assembly into the housing of the motor can significantly reduce the dependence of the motor on the control host of the extracorporeal blood pump, the risk of communication failure between the motor and the control host, and the risk of malfunction of the motor driving-control assembly, thereby greatly improving the safety and reliability of the extracorporeal blood pump.
