Abstract: An apparatus for installing, at the front end of an instrument panel, an aircraft instrument having a rectangular chassis. The installation occurs by advancing a screw through a corner adaptor, into the instrument. The adaptors are attached to the periphery of a rectangular hole in the instrument panel, after the instrument has been inserted therethrough, so as to create an octagonal hole as is typically found in instrument panels. The corner adaptors are made up of a first plate and a second plate having a spacer region which is slightly narrower than the thickness of the instrument panel. When a screw is inserted through the first plate and the second plate, they are held together and adhere to the instrument panel which is inserted therein.

Abstract: There is disclosed a system and technique for providing an audio verification of Global Positioning System (GPS) receiver signal acquisition. In a GPS receiver, the correlated output of the GPS signal is generally represented as a data modified CW signal with a Doppler component caused by the movement of a GPS satellite with respect to the receiver. Due to the Doppler component, this signal output provides a signature which is indicative of the particular satellite from which the signal is being received. The signal output is mixed with a local oscillator to produce a beat frequency in the audio band which may be filtered and coupled to an audio amplifier to produce an audio tone. The presence of the audio tone indicates the acquisition of a selected satellite signal and its audio frequency is indicative of the particular satellite signal being received.

Abstract: A Compact Reduced Parasitic Resonant Frequency Pulsed Power Source at Microwave Frequencies is disclosed which uses a series of stacked IMPATT diodes with thick metallic heat sinks interposed between each of the IMPATT diodes with the effective heat sink of each heat sink being roughly equivalent to the diode radius in length. The effective heat sink length is matched through the disclosed analysis to the effective heat sink of the base heat sink which is located at the bottom of the stack of IMPATT diodes. The diodes are operated in a pulsed fashion and the effective heat sink length is matched to the effective heat sink of the base heat sink that the temperature of the stacked IMPATT diodes track together in time.

Abstract: A method and apparatus for manufacture and repair of thermally durable surface mounted device printed wiring assemblies which includes a printed wiring assembly having surface mounted devices thereon, which are attached to said wiring assembly by a quenched or rapidly soldified soldier joint. A method for manufacture and repair of such printed wiring assemblies is to heat the TWAs with SMDs thereon, above the solder melting temperature, and then expose the solder to a fluid below the solder melting temperature which is capable of absorbing heat rapidly from the solder. The intermediate solder joint is thereby rapidly solidified to achieve the advantages of the investive method.
