Abstract: A diffuser provides a conductive path to ground for potentially damaging dielectric energy carried on the protective shield conductor of a telemetry cable, and acts to protect the cable's signal-carrying conductors, as well as connected devices, from potentially damaging dielectric buildup. The diffuser includes a circuit with one or more suppression elements. The suppression element(s) is normally in a high impedance state. When transient voltages and/or currents are present (e.g. as a result of lightning), and dielectric energy is carried on the shield conductor, the suppression element(s) rapidly switches to a low impedance state, and a dissipating or diffusing path is created to divert the incoming energy to ground. When the transient is gone, the circuit returns to the idle, high impedance state. The circuit may further include a protective element connected in series with the suppression element.

Abstract: An enclosure mounting bracket kit for attaching an enclosure with an exterior flange to a post is described. The mounting bracket includes an elongated horizontal rigid bar having first and second elongated studs protruding from the front side surface for penetrating the mounting holes of the flange; at least one through-hole in each of the first and second studs transverse to a long axis of the stud so that when each of the first and second studs penetrates a mounting hole the through-hole penetrates the flange; first and second releasable pins for positioning in each through-hole and gripping each of the first and second studs respectively; a block attached to the rear side surface of the bar between the first and second studs, the block having a surface generally conforming to the outside surface of the post; an adjustable strap attached to the rear surface for encompassing the post; and a ratchet tensioning device pivotally attached to the rear surface for tightening the strap around the post.
