A device structure and system for connecting optical waveguides to optical transmit and receive components is described. In a disclosed embodiment of the invention, a collision avoidance system includes a position-sensing device that is operable to determine a position of the aircraft, and a communications system operable to support two-way communications between the aircraft and other similarly configured aircraft. The method includes, for each verification check, requesting data about the player from one or more data source providers. The control unit control the actuation of the relay. The dynamic document templates execute in a separate namespace from the application and preserve the state of data in the application. In addition, the catheter may be embodied as a basket catheter including a plurality of splines.
