A method, computer system, and computer program product for restricting access to digital content data. The method includes providing a flow of gas to a patient’s airway at a pressure, obtaining information from the range of 0 to 25 Hz of the frequency domain of the flow, and adjusting the pressure based on the information. Each electrode is respectively configured to provide an electrical stimulus. Other embodiments are described and claimed. The translator translates messages sent from the first communication system into a format compatible with the second communication system and vice versa. The first connector port of the first connector has an insulating mating tongue with a plurality of contacts thereon and an insulating protecting frame arranged side by side with the mating tongue along a longitudinal direction of the first connector and spaced away from the mating tongue.
