A network component is provided that includes a processor configured, upon the network component receiving an IMS emergency call from a user equipment 110, to detect in the emergency call an indicator requesting the network component to restrict presentation of private information related to the UE 110. A first stage performs a first block permutation and a second stage performs bit order permutation to effectuate a second group permutation. In some embodiments, determined sleep quality metric values are associated with a current therapy parameter set. The deployment process is accomplished without rotating the entire mechanism around a central axis.
