A membrane probing assembly includes a support element having an incompressible forward support tiltably coupled to a rearward base and a membrane assembly, formed of polyimide layers, with its central region interconnected to the support by an elastomeric layer. The universal transmitter is then operable to transmit the \u201clearned\u201d modulation pattern and transmission frequency to actuate a remote control receiver operable with the template transmitter. The spring plate is mounted on the bottom wall of the shell and has a main portion and a number of elastic arms extending outward from the two opposite sides of the main portion. All users’ session environment is updated by sending information on whether a specific user’s behavior is predictable or unpredictable and by retrieving the appropriate user behavior from the normal or exceptions sections in the local cache memory.
