Communication link including a cable containing four pairs of wires, three transmitters to transmit uncompressed video data and audio data over three of the pairs of wires to three receivers, and two transceivers to form a bidirectional multi data type communication link over the fourth pair of wires. Embodiments of the system include a frame holder on which the eyewear is placed, a locking mechanism that secures the eyewear to the holder, and a key that enables a user to holder unlock and to remove the eyewear from the holder. The one or more computing devices determine a context for a topic of discussion associated with the communication session. The control system also works to perform a deemed D-position hydraulic transmission control to ensure the running of the vehicle even if the shift lever position sensor is failing. When a failure of unlatching operation is indicated, the apparatus reverses the rotational direction of the DC motor and thus, turning the latch keys in an opposite direction to re-latch the cassette pod door onto the cassette pod so that the pod can be securely removed from the loadport without danger of accidental opening of the door.
