摘要： A fluid pump for generating a fluid stream (55) is provided. The fluid pump includes a first actuator (20) with a first vibration element, a second actuator (30) with a second vibration element, and a power source that is connected to the first actuator and second actuator to supply energy to the first actuator and second actuator. The fluid pump further includes a controller that is connected to the power source and controls the power source to vary the energy supplied to the first actuator and second actuator. The first actuator (20) and the second actuator (30) are arranged opposite to each other so that a first movement direction of the first vibration element is inclined with respect to a second movement direction of the second vibration element. The controller controls the power source so that the first vibration element moves towards the second actuator and the second vibration element moves towards the first actuator in a synchronous manner and thereby cyclically soaks in a fluid from the surroundings and ejects the fluid in a directed manner.

摘要： A magnetic field propulsion unit (1) comprises a first magnetic field generating device (10) configured to generate a magnetic field; a second magnetic field generating device (220) configured to generate a magnetic field; an energy supply unit (30) configured to provide the first magnetic field generating device (10) and the second magnetic field generating device (220) with electrical energy; and a control unit (40) configured to control the energy supply unit in accordance with a predefined switching scheme. The second magnetic field generating device (220) is a rod-like antenna that lies in a plane in which also the first magnetic field generating device (10) lies. The control unit (40) is configured to: supply the second magnetic field generating device (220) with electrical energy so that a second magnetic field surrounding the second magnetic field generating device is generated; supply the first magnetic field generating device (10) with electrical energy so that a first magnetic field surrounding the first magnetic field generating device (10) is generated; wherein the first magnetic field generating device (10) is supplied with electrical energy a predetermined period of time after the second magnetic field generating device (220) is supplied with electrical energy.
