Abstract: This invention relates to electrical connector terminal arrays, having interference canceling characteristics that meet or exceed the performance requirements of Category 5 components. The arrays are suited for producing connectors of the type for mounting to a printed circuit board. The connectors comprise a dielectric housing into which are mounted four pairs of electrical conductors. The conductors are arranged essentially in parallel fashion where the respective one ends thereof are spaced apart a first uniform distance, and the other respective ends thereof are spaced apart a second uniform distance greater than the first uniform distance. The conductors are further characterized by being arranged in a non-contact overlapping arrangement with the respective conductors of each outer pair in a single overlap of each other. The respective conductors of the center pair cross each other and then each crosses the adjacent conductor twice.

Abstract: A system for automatically measuring a clearance envelope about a path of travel in a specific embodiment includes a laser and a rotating reflector mounted on a moving vehicle for radially scanning the region around the path of travel in a direction generally perpendicular to the path of travel. A television camera is mounted on the vehicle and is responsive to light from the laser that has been reflected by objects located within the viewing field of the camera. The television camera is radially scanned and provides analog video signals representative of the radial distances between the reflector and the scanned objects. An analog video tape recorder is utilized to record on video tape the distance representative video signals together with binary codes or identification numbers identifying the camera radial scanning information.
