The present invention pertains to a cable comprising: \u2014at least one conductor coated by an insulation coating layer, \u2014a first protective layer surrounding said insulation coating layer, said first protective layer at least comprising, but preferably being made of a tetrafluoroethylene copolymer comprising from 0. ; and an arithmetic control circuit that performs operation to the optical characteristics of a pair of the eyeglass lenses based on an output of the CCD. The approach applies semantic analysis to identify and score entity relationships between the entity information classified in the cluster classifications, and based on the scored entity relationships, cluster relationships between the cluster classifications are identified. A fastener extends through the flashing aperture.
