56579675, Aug 19, 1997

Filed:

Aug 10, 1995

Appl. No.:

8/513577

Inventors:

Thomas D. Patrick - Sun City AZ

International Classification:

E04H 1716

US Classification:

256 19

Abstract:

A fence system having treated wooden posts set in concrete at spaced-apart locations. Galvanized metal stringers extend between the posts and engage the post at a mounting surface. The mounting surface defines a plurality of vertically-elongate slots through which fasteners extend. Pickets are secured to the stringers and are vertically oriented. The stringers are secured by fasteners such as screws. Preferably the stringers are formed from HDPE and expansion and contraction of the pickets is accommodated by the slots in the mounting faces of the stringers. The pickets are formed by grinding waste plastic and adding UV inhibitors and color if desired. The ground plastic material is extruded under heat and pressure and the desired surface treatment applied to simulate the appearance of natural wood fencing. The surface-treated extrusion is cut to the desired length to form individual pickets.

Abstract:

A forward looking infrared (FLIR) energy imaging device has been found to include components which are required by the receiver portion of a long-wavelength rangefinder. For example, the FLIR collecting lens system which focuses energy from a scene onto a sensitive, cooled detector array duplicates the function which must be performed by the laser rangefinder receiver. Thus an integrated laser/FLIR rangefinder comprises a laser transmitter for illuminating a target, and an IR energy optic channel having a FLIR for receiving IR energy and producing a visible image representative thereof, said FLIR including an afocal lens system for collecting and focusing energy from the target and energy from the laser return having a wavelength compatible with the band pass of the IR optics and detector onto a cooled sensitive detector. In one embodiment the cooled detector is one of the center detectors of the FLIR detector array, in another embodiment the laser return energy collected by the FLIR afocal lens is reflected by a reflecting chopper, inserted in the FLIR optical path during the dead time generated for scan interlace, to a detector other than one of the center detectors in the array and unused by the thermal imager, or in still another embodiment the laser return detecting detector is a detector other than the cooled detector's of the FLIR detector array and includes a separate cooler. The laser return detector is connected to a laser preamplifier for producing a laser return signal for the laser rangefinder electronics.
