Abstract: An electromagnetic weapon that includes semi-randomly arranged antenna elements and a central weapon computer. The antenna elements are coordinated to function as an active phased array capable of finding and executing a resonate mode of a target. The central weapon computer controls all the antenna elements, and is able to determine the location of all the antenna elements.

Abstract: A ball socket driver bit that includes a ball portion and a shank portion. The ball portion has a ball portion cross section; the ball portion cross section perpendicular to the bit axis is hexagonal. The shank portion has a cross section smaller than the ball portion, and ag first shank portion end and a second shank portion end. The first shank portion end is axially attached to the ball portion, the second shank portion end is adapted to axially enter a socket head screw. The ball portion is adapted to enter a socket such that when turning the socket the socket head screw can be turned when the socket axis is not axially aligned with the screw axis.

Abstract: A rectangular sheet of flexible and resilient material such as plastic with notches at the midpoint of its sides. The size of the sheet and notches allow the insert to be placed into and located by a cell of a chain link fence. Notches fit around the wire crossovers of the chain link fence and locate the insert at the mid-plane of the fence. The corners of the insert extend into adjoining cells. Adjoining inserts overlap to provide complete visual privacy. The tile-like nature of the inserts allows great flexibility in arrangements and colors to provide visual privacy, decoration, words, logos, or signage.

Abstract: A polyhedral-shaped inflatable structure having substantially continuous inner and outer flexible surfaces is inflatable with air or gas so that a radar reflector, comprising a plurality of conterminous corner reflectors, is thereby positioned within the inflatable structure to reflect radar waves. The corner reflectors are preferably made of metallized reflective plastic film attached to a plurality of support filaments. Support members attached to the support filaments are pivotally disposed adjacent to the inner flexible surface to position the radar reflector within the inflatable structure. Removable fasteners are disposed adjacent to the outer flexible surface and concentrically proximate to the support members to thereby fasten the radar reflector to the inflatable structure without puncturing the inner and outer flexible surfaces.

Abstract: Disclosed herein is a method of detecting relative vibration between an AUT and a probe during any type of near-field testing. The method also provides the means to measure and compensate for any data inaccuracies/errors created by relative vibration while requiring no additional hardware other than that normally utilized in conducting a near-field test. In contrast to the standard process of collecting data only at a series of discrete points, data is collected regularly as the probe moves with a constant velocity across its measurement plane or virtual surface. Due to the constant collection of data, each principle data point is accompanied by a series of leading and trailing secondary data points. While the principle data points are, as in a standard near-field test, transformed by a computer to determine the AUT's far-field pattern (or to identify malfunctioning antenna elements), analysis of the secondary data points reveals any relative vibration between the AUT and the probe.

Abstract: Abstract: The storage roof truss has a non-triangular central opening to provide greater storage space. Truss chords and webs are arranged to provide a central opening with a horizontal bottom and vertical lower sides. This allows more usable storage space. The central opening chords and webs are connected to the top chords in a triangular mesh pattern such that loads on the element junctures are carried in tension or compression. This allows similar structural efficiency as a conventional truss. Therefore roof storage trusses can be constructed with similar costs as conventional trusses. Also, storage roof trusses can have the same range of pitches as conventional trusses.

Abstract: A SCARA type robot with counterbalanced arms and tilting base. This apparatus enables accurate planar movement of a probe. Weak or flexible foundations or footings do not affect positioning accuracy of the probe. Positioning accuracy, relative to the movement plane, of a probe is unaffected by positions of the arms. At any angle of the probe movement plane the counterbalanced arms allow the same size drive motors, torque transmission devices, and drive electronics. These features make the invention very useful for on-site or portable near-field testing of antennas. A manipulator may be used in place of the probe. Most of the benefits will be retained if load variations on the manipulator are kept small.
