Method for transferring signal between wall and wing hinge-articulated around hinge axis at wall, involves supplying signal modulated secondary voltage to signal transfer coils arranged at wall or wing by inductive coupling

摘要

The method involves arranging the signal transfer coils (28,34) on the wall (W) or at the wing (F), for supplying the signal modulated carrier voltage. The signal transfer coils are arranged at the wall or at the wing by an inductive coupling, for supplying the signal modulated secondary voltage. The carrier voltage is amplitude-modulated by the signal frequency, and is phase-modulated by the signal. The carrier voltage is a sinusoidal alternating voltage with the carrier frequency of 20 kHz. An independent claim is included for device for transferring signal between wall and wing hinge-articulated around hinge axis at wall.
