Abstract (en)
[origin: EP0736639A1] Moisture is driven from the wall (1) by the field radiated at preferably the most effective frequency of 141 kHz from a coil (L) driven by the VCO (6). A mains power unit (2) delivers also a low-frequency signal (S1) serving as a reference for the phase comparison (3) of the output (S4) from a 1410:1 frequency divider (4). A variant embodiment with better electromagnetic compatibility incorporates a pulse modulator applying a sequence of exponentially decaying pulses, and a switched frequency divider supplying an additional signal at 50 Hz.
