Abstract: A method and system for providing Triple Play services using GE-PON technology on a conventional network system, including coupling VLAN bridging to an optical line termination unit by dedicating a GE-PON logical link for each one of voice, data and video as inputs and outputs of the optical line termination unit, and coupling VLAN bridging to each optical network terminal by dedicating a GE-PON logical link for each one of voice, data and video as inputs and outputs of each optical network terminal, wherein a signal out of each optical network terminal is routed to a residential gateway that comprises a dedicated GE-PON logical link for each one of voice, data and video.

Abstract: A lifting foil for an aircraft, a hydrofoil or the like having a pair of courses or wings. Vortex losses due to spanwise fluid flow are substantially reduced by joining the tips of the courses with flow guides configured for jointly terminating the undesired flows. Termination is effected by providing the flow guides with crossections cambered for reducing the dynamic pressure of fluid flowing in a spanwise direction across flow guide surfaces.
