The invention relates to a system for limiting horizontal movements in a lift for humans or equipment in eg. In a particular embodiment, a mobile communication device wirelessly receives a plurality of media and stores the plurality of media in the mobile communication device. An anti-rotation gear is positioned inside the housing. In another aspect, the rate adaptation component removes a predefined codeword from the data stream and transforms another predefined codeword in the data stream into a second identification codeword in response to a determination that the first clock rate is greater than the second clock rate. According to the invention, the radiating element is located facing the surface of the earth plane so as to interact with the latter in order to improve its performance. The bar can be moved from a lower position to an upper position to form a barrier to keep children out of a tub.
