Abstract: Apparatuses and methods for hanging a plurality of sensors from an overhead strand holding one or more communication cables are described herein. In an example embodiment, a monitoring device includes a first housing portion including a bottom surface and a plurality of side surfaces, wherein at least one of the bottom surface and the plurality of side surfaces includes at least one aperture configured to receive a sensor, a second housing portion configured to attach to the first housing portion, thereby providing an inner space between the first and second housing portions, an attachment device enabling the attached first and second housing portions to hang from an overhead strand, and a connector configured to receive power from a communication line tap to power at least one component within the inner space while the attachment device hangs the housing from the overhead strand.

Abstract: Electrical contact with the target electrode of the tube in a tube/coil assembly is made by disposing a wire tangentially to a radial periphery about the longitudinal axis of the tube to create an interference fit between the wire and the electrode.

Abstract: An image pickup tube is rigidly centered and mounted to a coil assembly by an adjustable split-ring clamp of hard plastic material mounted to the coil assembly. The split-ring clamp when adjusted for mounting compresses about the periphery of the faceplate or anti-halation disk extension of the tube to thereby provide a rigid mounting between the coil assembly and the tube. The rear portion of the coil assembly includes a yoke with a tapered inner surface. A split-ring wedge is forced between the tube and the rear portion of the yoke to rigidly support and center the rear portion of the tube.
