Methods and systems for storing data securely in a secure data storage network are disclosed. The deployment mechanism includes a tubular cam having a retention mechanism that retains the fin simply and reliably in the stowed orientation. These stimulation trains are generated to target a specific neurological disorder, by arranging sets of features which reduce symptoms of that neurological disorder into a pattern which is effective at reducing those symptoms while maintaining or reducing power consumption versus regular stimulation signals. The front panel defines a screw hole. Bad data packets thus do not consume space in a central queue nor bandwidth in a crossbar switch.
