A subcutaneously implantable distraction device comprises a first arm, having a first skeletal connector for attachment to a first skeletal component at a first location. The method involves discovering the active channel changing sequence used by the network, synchronizing communications of a new node with the remainder of the nodes in the network and scanning communications channels to detect merging clusters of nodes. In one generalized non-limiting embodiment the antennas are fabricated on FR-4 epoxy boards. A second station, representing the user, forwards the request and user identity information to a third station. In the video magnifier, in synchronization with irradiation of the photographed part of the object by the pointer, an illuminance of the illumination lamp is rendered lower than an illuminance of the pointer.
