Abstract: A solar light assembly is configured for illuminating a corrugated sign. The assembly comprises a solar panel, a battery, and a printed circuit board electrically connected to the battery and to the solar panel. An LED light is disposed on the printed circuit board, which is curved to direct the light onto a printed surface of the sign. A sign attachment component attaches the assembly to the corrugated sign. The sign attachment component may be one or more spears configured to be inserted into flutes of the corrugated sign.

Abstract: Flying electric generator aircraft that include groupings of four rotors mounted to booms extending fore and aft of a fuselage structure wherein the rotors are placed so that when the aircraft is facing the wind, each rotor has a direct path to an undisturbed flow of air, regardless of pitch angle and during all flight maneuvers of the aircraft. The rotors are placed in counter-rotating pairs with the booms preferably angled so that the rotors in the front of the aircraft are spaced at a distance from one another that is different than a spacing of the rotors at the rear of the aircraft.

Abstract: An improved power supply and platform for a military radio has been developed. The apparatus includes a base that is adapted and arranged for supporting a HARRIS 117 radio and a power amplifier adapted to amplify radio frequency output of the radio. The connectors include an electrical connector for the radio and a connector for the amplifier. A power supply is housed within the assembly. A power supply for the connector to the amplifier is also housed within the assembly. Also included is a wiring harness for a SINCGARS LS/671 device and a LED indicator to identify which radio is in operation for multiple radio configurations.

Abstract: A directional alignment and alignment monitoring sensor system that is designed to be mounted to a directional or omni-directional antenna wherein the system includes a sensor having one or more phototransistors that are associated with one or more baffle members and wherein each baffle member defines a restrictive light passageway toward a phototransistor such the by measuring the time that a phototransistor is illuminated, a correct orientation of the antenna may be accurately determined.

Abstract: An anti-collision light for large, commercial aircraft is disclosed. The light is a self-contained unit capable of easy replacement of any anti-collision light currently in use in any large aircraft using an adapter plate and adapter cable directly connected to 115 VAC 400 cycles from the aircraft. The light includes a plurality of round circuit boards with an annular ring of high intensity, surface mounted LEDs, with a disk having an edge configured as an offset half parabolic reflector made up of a plurality of conical facets. Angles of the conical facets are selected such that light from the LEDs is focused into a plurality of discrete planes from each facet, these planes concentrating the light into planar regions of discrete light intensity as required by the FAA. The disks with reflector edges also serve as heat sinks to dissipate heat developed by the LEDs.

Abstract: A tool and method for aligning directional antennas quickly and accurately in azimuth, tilt and roll. The tool includes a housing, mounting brackets for securing the tool to an antenna, a data storage device including predetermined alignment information, a GPS system for measuring azimuth, and inclinometers for measuring tilt and roll. The tool also includes displays for displaying the measured values of the azimuth, tilt, and roll relative to the predetermined parameters. As a result, a user can easily align an antennas based on the azimuth, tilt, and roll information measured and displayed by the tool.

Abstract: A passive capture joint with three degrees of freedom is presented wherein two structural elements are joined together solely by moving the two elements into position, and which when joined together have rotation in all three axes. The inventive apparatus is comprised of two halves: 1) a joint ball mounted on a stem as in a common trailer hitch, and; 2) a socket. The socket consists of a base having an exterior wall and forming an interior chamber, the chamber having a top end and a bottom end, and an interior wall. The chamber is open at the top end, and forms a spherical cup at the bottom end. The socket base's interior chamber is sized to accept the joint ball. The base also forms at least one bore at an acute angle away from the interior chamber's open end. The bores have a first opening in the interior wall of the chamber, and a second opening in the exterior wall of the base.
