Abstract: A protective enclosure for electronic devices (110) includes a tube (112) formed from conductive polyvinyl chloride and comprising a bottom wall (116), side walls (122, 124) and a top wall (126). The top wall (126) includes a gap (128) to permit observation of electronic devices supported on the central portion (120) of the bottom wall (116). A transparent window (114) formed from transparent polyvinyl chloride is positioned on the outer surface of the top wall (126) and extends across the gap (128).

Abstract: An articulated highway delineator post assembly which includes an elongated, vertically extending indicator support post telescopingly engaged with a resilient slotted tubular sleeve. The support post is connected to the sleeve by a pivot pin assembly allowing pivotal movement of the support post about a horizontal axis to project a portion of the support post through the slot in the sleeve. The slot in the resilient sleeve is dimensioned in relation to the dimension of the support post to continuously resiliently urge the support post toward a vertical position when it has been inclined from the vertical at an acute angle upon pivotation and extension through a portion of the slot. The assembly further includes a ground post extended into the earth and projected at its upper end into one end of the tubular sleeve for supporting the sleeve and the support post above, and in substantially vertical alignment with, the ground post.
