Method for contactless transmission of electrical energy and/or electric signal between wall and wing of door of e.g. house, involves producing interference signal during unloading or non detection of preset part of expected control signals

摘要

The method involves providing coils (19, 20) fastened to a wall and a wing, respectively. The coils are found in inductive active connection. One of the coils (19) is loaded with a control signal, and a signal induced in the other coil (20) is detected in a preset time interval. The latter coil is loaded with a response control signal, and another signal induced in the former coil is detected in the time interval by primary and secondary electronics (38, 39). An interference signal is produced during unloading or non detection of a preset part of expected control signals. An independent claim is also included for a device for contactless transmission of electrical energy and/or electric signals between a wall and a wing fastened to the wall. The primary and secondary electronics include a housing made of heat conductive plastic.
