Abstract: A method and system for monitoring a fleet-angle of a cable. An embodiment may monitor the fleet-angle of a cable being spooled or unspooled in multiple radial directions and without use of a mechanical monitoring apparatus. The method and system may employ a fleet angle sensor device having a bell-shaped aperture across which propagate one or more collimated light beams that may be used to detect excessive fleet-angle of the cable. The light beams may be generated by a fleet-angle sensor disposed in the fleet angle sensor device proximate to the aperture. Various light-beam patterns within the aperture may provide different advantages when determining deviations of the cable from the aperture center axis.

Abstract: Semiconductor sensor chips are assembled with semiconductor communication chips to form sensor nodes which are wired together and placed in a tube preform which is sealed to form a tube containing an array of sensor nodes. The tube, resembling a wire in appearance, can then be assembled with power conductors to form a power delivery cable to allow monitoring of conditions within the cable at a plurality of spaced locations along the length of the cable so that the cable can be operated near or at its actual current carrying capacity which may be altered by ambient conditions and allowing management of risk of failure of the cable.

The tube, resembling a wire in appearance, can then be assembled with power conductors to form a power delivery cable to allow monitoring of conditions within the cable at a plurality of spaced locations along the length of the cable. By monitoring conditions at spaced locations within the cable during use, the cable can be operated near or at its actual current carrying capacity which may be altered by ambient conditions such as the shape of the cable, strain applied thereto, damage, or whether the cable is partially wound on a spool or reel that prevents dissipation of heat due to ohmic losses in the cable; thus allowing management of risk of failure of the cable without a requirement for additional, generally unused current carrying capacity in the design of the cable.
