Abstract: In order to configure a communication device connected to a wireless network including N communication channels, the communication device being adapted for communicating via one communication channel at a time, means of selection of a channel from amongst the N communication channels enables: selecting a communication channel with an unknown disturbance level, when the disturbance level of at least one communication channel is unknown; and otherwise selecting the least disturbed communication channel. Dynamic configuration means include means for reactivating the selection means in case of disturbances representing unsatisfactory transmission conditions on the selected communication channel according to a predetermined criterion. The dynamic configuration means are deactivated when the selection means have been reactivated N times.

Abstract: A docking device for a hard disk has a protective box housing an electronic unit including a printed circuit card and a fan arranged in or in the vicinity of an opening formed in a first wall of the protective box. The box also has a location for a hard disk. The fan is arranged in the vicinity of an edge of the printed circuit card so that the air stream driven by said fan sweeps over both main faces of the printed circuit card. The guide is designed to guide at least a portion of the air stream driven by the fan directly to the location for a hard disk.
