A method for assessing and responding to a level of awareness of a flight crew member onboard an aircraft is provided. A plurality of electrical cables is bundled together and positioned within the lumen of the flexible member. By doing so, the mechanism exposes only the shared L2 address to the network, and shields the actual L2 addresses of the hosts from the network. In an alternative embodiment, the inner assembly rotates within the stationary assembly. A power supply part converts an external power supply voltage to an internal power supply voltage and supplies the internal power supply voltage to the sense amplifier part.
