The invention is directed to techniques for managing data distribution in a network. The first component is retained proximate to the second component by a locking mechanism. The apparatus also includes a motor module attached to an end of the base assembly. , or R3, R4, R5, R6 and R7 may form a ring which may be substituted, which is formed by the adjacent two of them with carbon atoms to which the respective substituents are bonded,m and n each independently represent 0 or 1. There is further step of winding the windable product in layers substantially parallel to the lower conical surface up to the top conical surface, and the winding layers end respectively in a cylindrical surface connecting the circumference of the two flange discs. A mobile electronic device is provided, comprising a radio transmitter circuit, an antenna connected to said radio transmitter circuit, and a controller adapted for transmitting a radio transmission using said radio transmitter circuit, detecting a change in transmission conditions, and adjusting the power radiated by said antenna in response to a detected change.
