A method and apparatus is provided for a multiple light-source illuminating device, the design and construction of which is derived from the lighting requirements of a specific lighting application. The resulting illuminating device (16) provides illumination according to the principles of lighting practice for the optimal performance of visual tasks. Coupling with sensors (21) and logical control (20) allows illumination intensity and spectrum to be varied according to changing user needs. The illuminating device includes multiple discrete light emitting components of different spatial intensity distribution and color spectrum mounted in specific orientations such that the application oriented combined lighting effect is created. The control is provided via a differentiated power supply (19) capable of affecting the current, voltage and duty cycle determining the relative contribution of each light source effecting a different spatial intensity distribution and color spectrum.

An unmanned air vehicle designed for reconnaissance, surveillance, data acquisition, and general research. The vehicle is a monoplane that is comprised of several pieces that can easily be assembled using a minimal amount of tools. The aircraft consists of a forward and aft fuselage section, two identical horizontal stabilizers, and four identical wing sections. The aircraft can fly with all four wing sections, or with just two wing sections (the short wing configuration). This makes the aircraft usable for missions requiring short takeoff and landing and high endurance (long wing), or missions requiring higher speed and range (short wing). No other UAV (or other aircraft) has this unique feature. Another novel aspect of the present invention is the wing control can be specially designed to increase the effectiveness of the wing control surface while minimizing the effect the control surface has on the overall aerodynamics of the wing, namely drag.

A fast line maintenance repair process for damaged composite structures includes the application of a pre-cured patch that uses a quick curing paste adhesive to bond the patch to the structure. The adhesive is cured at relatively low elevated temperatures provided by a chemical heat pack. The low temperature cure eliminates the need to dry out the part and permits the application of the repair in a hazardous environment. In a typical commercial airline application, airline maintenance personnel can install the repair at the flight gate. The repair is intended to restore the structure to a desired load capability in approximately one hour. The repair can be removed if need be with less overall damage than would occur upon removal of typical mechanically fastened repairs. All or some of the repair materials and tools can be provided in a portable kit.

The present invention's composite-to-metal attachment methodology—bolt-free and adhesive-free—features the implementation of an intermediary structure containing metallic fibrous material. The intermediary structure couples a first adherend (which contains nonmetallic fibrous material) with a second adherend (which contains metallic nonfibrous material). The intermediary structure's fibrous attribute is availed of for effecting its co-cure attachment to the first adherend. The intermediary structure's metallic attribute is availed of for effecting its weld attachment to the second adherend. According to typical inventive practice, respective panels of the first adherend and the intermediary structure are arranged and connected so as to describe a stepped configuration at the interface between the first adherend and the intermediary structure. The first adherend and a first portion of the intermediary structure are co-impregnated with a uniform resinous system and are co-cured. A second portion of the intermediary structure is welded with respect to the second adherend.

Firearms where the bolt catch, magazine, or both, can be released from either side using the same or a substantially similar motion using contact features that look, feel, or operate similarly on both sides, that are located within the firearm rather than externally, that can be used more easily or reliably, or a combination thereof. In some embodiments, a bolt catch engagement feature is similarly ambidextrous. In many embodiments, a user action on one side of the firearm is substantially similar to, but in the opposite direction from, a user action on the other side that performs the same function.
