摘要:
A blood pump (20) includes a stator assembly comprising a motor stator (52), a fluid inlet (24), and a fluid outlet (26). A rotor assembly includes a motor rotor (54) and an impeller (40) rotatable about an axis (44) to move fluid from the inlet (24) to the outlet (26). An outflow sheath (300) directs the flow along the outside of the pump (20).

摘要:
A blood pump (26) includes a stator assembly including a fluid inlet (24) and a fluid outlet (26). A rotor assembly (120) includes an impeller (40) rotatable about an axis (44) to move fluid from the inlet (24) to the outlet (26). A motor (50) imparts rotation of the impeller (40) about the axis (44). The motor (50) includes a motor stator (52) fixed to the stator assembly (122), a motor rotor (54) fixed to the rotor assembly (120), and a radial motor gap (34) between the stator (52) and the rotor (54). The pump (20) is configured to direct a mixed blood flow from the fluid inlet (24) to the fluid outlet (26) and a wash flow through the motor gap (34).

A blood pump (26) includes a stator assembly (122) that includes a motor stator, a fluid inlet (24), and a fluid outlet (26). A rotor assembly (120) includes a motor rotor (54) and an impeller (40) rotatable about an axis (44) to move fluid from the inlet (24) to the outlet (26). A permanent magnet radial bearing (100) supports the rotor assembly for rotation about the axis (44). The radial bearing (100) includes a permanent magnet radial bearing stator (106) fixed to the stator assembly (122) and a permanent magnet radial bearing rotor (108) fixed to the rotor assembly (120). The radial bearing (100) is configured such that the radial bearing stator magnets (106) and the radial bearing rotor magnets (108) are axially offset from each other when the pump is at rest.

A silencer is described for damping the outflow noise of compressed air from compressed air appliances, in particular compressed air appliances of vehicles, with an inlet port, with at least one outlet port and with a pot-like housing which is arranged between these ports and which has a pot casing and a pot bottom, a sound-absorbing material in the form of a cartridge of a filter knit, serving for noise damping, being arranged in the inner space of the pot-like housing, characterized in that a layer of fibrous material is arranged between the cartridge and the pot casing.
摘要:
A circuit chip has an apparatus for an electrically conductive connection of a terminal thereof to an external reference potential. The apparatus has a parallel connection of a bonding wire and a semiconductor area formed in a substrate of the circuit chip. The semiconductor area is doped higher than the substrate of the circuit chip.

A circuit for providing a base operating voltage for a bipolar transistor includes a UBE multiplier providing, in response to a working-point control current, a working voltage fed to a circuit for reducing the working voltage in order to generate a base operating voltage smaller than a base-emitter voltage drop of a bipolar power transistor. With this, the bipolar power transistor may be maintained in the class C operation in a flexible and robust manner, so that an amplifier with high efficiency is obtained.
摘要:
A method is described that involves locking a capacity demand profile of a resource for the use of a transaction. The method also involves obtaining a portion of the locked capacity demand profile. The portion describes the capacity demand profile over a time interval in which a locked out transaction desired to implement a change to the capacity demand profile prior to the locking. The method involves implementing the change to the portion to form a changed portion. The method also involves, after the implementing, implementing a second change to the changed portion. The second change is desired by the transaction.
摘要:
A circuit configuration for digitally setting analog parameters includes at least two analog multiplying devices each having a differential amplifier stage. The differential amplifier stages have differential inputs connected in parallel with one another and driven by an analog bipolar input signal. The differential amplifier stages have outputs coupled to one another cumulatively. The differential amplifier stages receive supply currents which are to be switched on and off individually as a function of a corresponding digital control signal and are graded using binary code.
