20090073654, Mar 19, 2009

Filed:

Sep 14, 2007

Appl. No.:

11/898668

Inventors:

James M. Beam - Montgomery AL, US
Bernard A. Kuster - Longmont CO, US
Jeffrey Allen Wilson - Wetumpka AL, US

International Classification:

H05K 7/20

US Classification:

361696, 16510434

Abstract:

A temperature-stable portable device includes equipment enclosed in a portable case that seals the equipment from its surroundings, and a heat exchanger distinct from the case and attached to the exterior of the case by removable fasteners. The heat exchanger extends across at least most of a major surface of the case and is positioned to receive heat from the major surface by conduction. A sheet of material having good thermal conductivity is interposed between, and in contact with, the heat exchanger and the major surface of the case. The heat exchanger defines a chamber that is open to the atmosphere and has parallel flow passages and an arrangement for moving a heat exchange fluid through the chamber and out to the atmosphere in order to remove heat from the heat exchanger by convection.

Abstract:

A dipole antenna structure that includes a sheet of metal that forms elements of a dipole antenna. The sheet of metal includes a first arm, and a second arm connected to the first arm, and formed substantially co-planar with, and non-parallel to, the first arm. The sheet of metal further includes at least one impedance matching element connected to the first arm and the second arm, where the at least one impedance matching element is formed in the sheet of metal at an angle relative to a plane that coincides with the substantially co-planar first and second arms.
