Abstract: Systems and methods are provided for splicing airframe components. One embodiment is a method for assembling an airframe of an aircraft. The method includes forming a first skin of a first circumferential section of fuselage, the first skin including a distal portion comprising a lip and a shoulder, aligning a second skin of a second circumferential section of fuselage with the shoulder such that the lip overlaps the second skin, and affixing the first skin and the second skin together via a circumferential splice.

Abstract: A downhole tool comprises a plurality of blades that extend outward from a tool body. Each blade has an under-gauge surface with a blade diameter that is less than a gauge diameter of a drill bit to be used with the downhole tool. A waterway is defined between a pair of adjacent blades and has a waterway base that is recessed from the blade diameter. One or more waterway inserts are disposed within the waterway and extend from the waterway base. Each of the one or more waterway inserts does not extend to the blade diameter. No component of the downhole tool is positioned outside the blade diameter.

Abstract: A method and apparatus is provided for allowing an individual to preview how a tattoo will look on their body before they have the design tattooed. By digitally storing images of the individual's body and then overlaying this image with a tattoo design, the individual can modify the tattoo design until they are happy with how it looks.

Abstract: An injection-locked variable-frequency high-power microwave frequency generator includes an injection source, a circulator, and an oscillator. The circulator includes an injection port to the injection source, an oscillator port to the oscillator, and a transmission port. The circulator directs the injection signal from the injection source into the oscillator and directs the oscillator output out the transmission port. The oscillator includes an IMPATT diode and a microstrip matching circuit. The matching circuit provides the sufficient conditions for broadband (9.1-9.5 GHz) oscillation of the diode. To this end, the matching circuit provides three resonators having three different but closely coupled resonant frequencies. The matching circuit also serves as a transformer, providing impedance matching to the circulator. A high-power output can be chirped or otherwise controlled by electronic control of the injection frequency.

Abstract: A video switch having at least two inputs from separate frame buffers and being controlled by a select control signal as to which buffer signal will control the electron guns in the cathode ray tube. The determination of which frame buffer signal is applied on a pixel-by-pixel basis is determined by priority bits from priority buffers. In case of a tie in priority, a tie bit is provided.

Abstract: A GaAs/AlGaAs heterojunction IMPATT diode is described. The AlGaAs n-type avalanche layer is graded so that a 0.30 eV bandgap discontinuity of the pn heterojunction is provided without any bandgap discontinuity at the avalanche/drift layer interface. Minority carriers in the p-type GaAs layer are concentrated at the junction due to the discontinuity which occurs primarily in the conduction band thereby concentrating the zero bias electric field and thus minimizing the voltage drop across the avalanche layer. Furthermore, the zero bias depletion width is increased due to the increased field, which lowers the device capacitance.
