A particular failed connection attempt initiated by a particular source asset in a network is identified and subsequent failed connection attempts initiated by the particular source asset in the network during a time period are tracked. The locking mechanism includes an articulated member attached between the cabin unit and the horizontal platform, the articulated member including an upper support arm and a lower support arm coupled at a joint and a cylinder attached between the horizontal support and the articulated member. The invention also includes novel cation exchange membranes with or without woven support membranes and their methods of formation. The analyzed areas are displayed on an image-display device according to a predetermined criterion. The driver module generates a first drive signal proportional to the dynamic power control signal when a bit in said digital amplitude signal is a logic one and the driver module generates a second drive signal proportional to the second differential signal when a bit in said digital amplitude signal is a logic zero.
