The novel braking resistor consists of a power electronic circuit, with which the braking energy can be fed back to a three-phase system. The recovery of braking energy can thus save energy, reduce costs and relieve the burden on the environment.

The novel rotary piston pump operates with permanent magnets, which are arranged at the vertices of a piston rotor. In the pump housing coils are arranged, which generate a rotating magnetic field with which the piston rotor is driven. As a result, a seal-free drive is realized, which dispenses with.....

The dualmode-radio uses two free space modes for the transmission of signals at the same frequency. The transmitter signal provides not only the useful signal but also an orthogonal signal for demodulation. This eleminates the need for the local oscillator in the reciever, which means significant sa.....

In order to improve the insulation properties of the E-RFS, signals applied to the input of the RFS are attenuated and inverted by the electronic network and then added again at the output of the RFS so that the output signal of the E-RFS is significantly smaller overall than the signal transmitted .....
