Abstract: Provided is a modified configuration that permits operation of instrumentation onboard platforms that may experience severe environmental conditions. The instrumentation permits autonomous acquisition of performance data. Acquired data may be recorded for later playback as well as provided to the platform's operator in real time in multiple formats, such as warning lights, digital displays, video, or audio. An application would be for sensor systems used on an automobile to record performance data, providing a warning when routine maintenance is due or a catastrophic failure is imminent. A specific application uses a flight-certified missile launcher pod on an F/A-18 aircraft, as incorporated in the aircraft's wingtip and modified to hold instrumentation conforming, at least in part, to the launcher pod's internal dimensions.

Abstract: Processing GPS signals received at moving targets and at a fixed location near instrumentation associated with timing and recording an event allows the determination of instantaneous target position to be made without a requirement for additional active tracking. An example is the recording and display of a test event involving a missile intercepting a target. The missile, target, and an instrumentation site all receive GPS signals. The signals are time tagged and the data contained thereon verified by a source and forwarded from each platform to a ground station. The data is correlated with other test data to provide a real time record and display of the missile intercepting the target. Both Time Space Position Information (TSPI) and Miss Distance Indication (MDI) are derived to a very high degree of accuracy using double difference error correction techniques. Both absolute and relative position information can be derived.

Abstract: A magnetic roll rate sensor for measuring the roll rate or roll position of a missile. A pair of magnetic sensor elements mounted within the missile provide analog electrical signals representative of a change in the earth's magnetic field due to the presence of a ferromagnetic element within the field. The analog signals, representative of roll rate sensor data, are converted to a digital format, formatted into a PCM data stream and transmitted to a ground station. The ground station receives the PCM data stream, extracts the roll rate sensor data and processes the data using a personal computer to determine a roll rate for the missile.

The microstrip antenna system is designed for use on small diameter airborne projectiles which have a diameter of about 2.75 inches. A pair of band stop filters are integrated into the antenna system to isolate the transmitted telemetry signal from the received GPS signal.

Abstract: A signal processing circuit is disclosed for providing fuze-on-jam capability in a target detecting device, while in the presence of continuous wave or continuous wave noise jammer signals. A target detection system will protect the target detecting device from noise jammers and continuous wave radars or continuous wave jammers by providing a circuit which samples the negative or positive bias produced by the noise modulated CW signal and produces either positive or negative polarity as seen by the antenna. If negative pulses are produced, they will actuate the target detecting gate and guard circuit and after the missile has passed the critical angle of the antenna the phase change will then produce firing in the normal manner. The sampled output is fed into the target detecting mixing circuit and no interference with normal operations of the target detecting device occurs while a fuze-on-jam or CW capability is provided.

Abstract: A method of removing contaminated sediment material from a contaminated area on the ocean floor using a reactor vessel wherein seawater is from within the interior of the reactor vessel so that the vessel penetrates the ocean floor. A pressurized fluid is introduced into the reactor vessel to create a slurry vortex of the contaminated sediment material and then a remediation fluid injected into the slurry vortex of the contaminated sediment material using a sufficient amount of the remediation fluid to remediate the contaminated sediment material and provide a noncontaminated sediment material. Pressurized seawater is injected into the interior of the reactor vessel to create a positive pressure within the reactor vessel to lift the reactor vessel above the ocean floor allowing for a transfer of the reactor vessel to another area of sediment contamination on the ocean floor.

Abstract: A swiveling hose coupling comprising first and second nipples and a cylindrical shell. The cylindrical shell includes a swivel shell, and first and second retaining rings. The swivel shell is set between the first and second retaining rings. The first and second nipples are in proximity with one another within the cylindrical shell, but are separated by antifriction bearings. The first and second nipple rotate independent of one another to prevent inhibition of liquid flow in a hose coupled to the swiveling hose coupling. The first and second nipples are set in the cylindrical shell, using journal bearing grooves on the first and second nipple, in which the journal bearing grooves abut the first and second retaining rings. Reference points for the application of a hose coupling clamp are provided by an indexing ring on each of the nipples.

Abstract: An annular after reactor is aligned axially with the direction of exhaust flow from the exhaust port of a jet engine under static test. Located near the front end of the reactor is a first set of gas injectors. A second set of gas injectors are located downstream from the first set of gas injectors within the reactor. The first set of gas injectors inject natural gas into the jet engine exhaust, while the second set of gas injectors inject ammonia into the jet engine exhaust. The natural gas when ignited raises the temperature of the jet engine exhaust which incinerates the particulate matter in the exhaust. Ammonia injected into the exhaust stream functions as a reductant to eliminate up to 90% of the NOX compounds in the exhaust stream. The reactor includes a jet engine exhaust buster assembly for substantially reducing noise generated by a jet's engine's exhaust.

Abstract: An adaptive cross polarization electronic countermeasures system comprising identical transmit and receive antennas. The transmit antenna is rotated 180 degrees with respect to the receive antenna. The transmit and receive antennas are mounted facing the same direction allowing for reception of an incoming RF signal from a monopulse radar and transmission of the signal back to the monopulse once ECM jamming is applied. The incoming RF signal is separated into vertical and horizontal components by coupling to vertical and horizontal feeds within the receive antenna. Each component is then amplified sequentially through the system and transmitted back to the monopulse radar. At the transmit antenna, the vertical component is transmitted out of the horizontal feed of the transmit antenna 180 degrees out of phase with respect to the feed. The horizontal component is transmitted out of the vertical feed of the transmit antenna with no phase shift.
