Patent number: 7652626Abstract: A direction-finding co-linear antenna is provided by collinearly aligning an exposed reference antenna with a primary antenna that is surrounded by a dielectric sleeve with a predetermined thickness and the reference and primary antennas are separated by a ground plane. The direction-finding co-linear antenna provides a simple, light-weight and inexpensive arrangement with fewer antennas and reduced antenna spacing that avoids unwanted detection because of a smaller electronic footprint that consists of the area of a single antenna plus a few inches of dielectric material in the sleeves rather than four widely spaced antennas positioned in an array. The direction-finding co-linear antenna apparatus also requires less electronic processing because the antenna only needs to address the RF from two antennas rather than from four or five antennas in a conventional array arrangement.Type: GrantFiled: December 5, 2007Date of Patent: January 26, 2010Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Ernest Potenziani, II, Michael T. Cummings

Patent number: 5438308Abstract: A yokeless magnetic circuit composed of a permanent magnet shell having a lenoidal-cavity within which a working field is generated. The permanent magnet shell has a conical permanent end magnet adjacent each of its ends to insure that the surface at each of its ends is equipotential between the radial periphery of the permanent magnet shell and the axial centerpoint of the solenoidal cavity. The height of the conical end magnets directly depends of the magnetization and thickness of the permanent magnet shell and whether the internal field is uniform, gradient or variable.Type: GrantFiled: November 8, 1994Date of Patent: August 1, 1995Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Herbert A.

Patent number: 4592889Abstract: A method and apparatus for pressing magnetic powder in a toroidal-shape we in a radial magnetic field. A magnetic flux is produced and carried by a die rod through the axial center of toroidally-shaped magnetic powder.
