A wearable device for transdermal product supply comprises a head, which houses two ultrasonic resonators in resonance, with an outer cavity. A first, more distal resonator emits towards the skin at a first frequency and a second, more proximal resonator surrounds the cavity and emits parallel to the skin at a second frequency. One frequency is high-frequency sonophoresis (HFS) and the other is low-frequency sonophoresis (LFS). The second resonator comprises a hole in order to enable the waves from the first resonator to pass through. The waves from the second resonator pass through the head, the hole and the cavity, bouncing off an opposite area of the head and interfering with the waves from the first resonator. The interference between the waves creates a stationary field which increases the permeability of the skin, enabling a device with a reduced size to be incorporated into a wearable.

A superconducting generator includes an armature configured to rotate about a shaft and a stationary field arranged concentrically and radially outward from the armature. The stationary field comprises a superconducting field winding and a vacuum chamber with an inner wall of nonmagnetic or paramagnetic material facing the armature, an opposing outer wall of ferromagnetic material, and several side walls connecting the inner wall to the opposite outer wall. The superconducting field winding is arranged within the vacuum chamber. A wind turbine and a method are also described. The wind turbine includes a rotor with several blades. The wind turbine also includes a shaft coupled to the rotor. Furthermore, the wind turbine includes the superconducting generator coupled to the rotor via the shaft.

The disclosure describes method and system for notifying a backend service of the presence of an e-scooter within a parking zone for e-scooters. The method comprising the steps of a) transmitting a communication signal by a stationary field appliance first transmitter of a stationary field appliance b) detecting the communication signal by a mobile field appliance receiver of a mobile field appliance, c) transmitting a response signal by a mobile field appliance transmitter of the mobile field appliance as a response to the mobile field appliance receiver detecting the communication signal, d) detecting the response signal by a stationary field appliance receiver of the stationary field appliance, e) determining, by the stationary field appliance, based on at least the detected response signal, whether the mobile field appliance is present within a distance L<100 meters of the stationary field appliance, and f) notifying the backend service, by the stationary field appliance, by means of the stationary field appliance second transmitter and the backend service receiver, whether the mobile field appliance is present within a distance L of the stationary field appliance.
