The invention is based on the idea that in an intelligent network the order of execution of service programs at one point during the call, such as the detection point, is defined, and the service programs are contacted in this order until instructions are received to leave the point or release the call. An ontology, which is in communication with each of the plurality of models, provides uniform definitions for the concepts and relationships between concepts used in the plurality of models. A path selector is provided to select one of a first path and a second path between the subscriber line and the feeder. The cover may comprise a cylinder having an axially running aperture, andor a beveled edge that shaves a layer of the outer surface from one of the plurality of pins as it is fitted over the pin. A manually adjustable screw adjusts the position of the motor along the slide to permit manual alignment of the headlight beam. An imaging apparatus comprises an imaging unit that includes an imaging chip and a mounting substrate that has the imaging chip mounted thereon and includes a first metal layer for outputting a signal generated by the imaging chip to the outside.
