Abstract: In one exemplary embodiment, a method comprises transmitting an optical signal via the optical line, measuring a relative change in spectral intensity of the optical signal near a clock frequency (or half of that frequency) while varying a polarization of the optical signal between a first state of polarization and a second state of polarization, and using the relative change in spectral intensity of the optical signal to determine and correct the DGD of the optical line. Another method comprises splitting an optical signal traveling through the optical line into a first and second portions having a first and second principal states of polarization of the optical line, converting the first and second portions into a first and second electrical signals, delaying the second electrical signal to create a delayed electrical signal that compensates for a DGD of the optical line, and combining the delayed electrical signal with the first electrical signal to produce a fixed output electrical signal.

Abstract: A self-propelled drill for drilling a bore or cleaning a pipe in straight and/or curved paths. The drill includes a piston having a working head which slides within a housing. A rotary piston driving mechanism featuring an endless groove converts longitudinal motion of the piston to a combined longitudinal and rotary movement of the working head. A housing gripping device fixes the drill to the wall of the bore to allow drilling while a working head gripping device fixes the working head to the walls of the bore to allow the drill to be periodically pulled forward.

Abstract: A driving mechanism transforms continuous longitudinal reciprocation of a piston in a chamber into unidirectional rotation. The mechanism utilizes a closed wave-shaped groove defined in either the cylinder or the chamber and adapted to receive guiding members projecting from the other of the piston and the chamber. When the piston is forced to move longitudinally in either direction, the groove slides over the guiding members to force rotation. The apices of the wave-shaped groove are either contoured or provided with a gating structure to assure that the guide members do not backtrack but instead move in one direction through the groove.
