Abstract: Provided is a self-contained, closed-loop cooling system for an air compressor, and a method of controlling a temperature of the compressor. The air compressor provides compressed air to an associated system. The air compressor includes a passage for a flow of coolant therethrough. A pump pumps an input flow of coolant into the air compressor, and a heat exchanger cools an output flow of coolant from the air compressor. Fluid delivery lines connect the air compressor, the pump, and the heat exchanger in a closed loop configuration, such that the coolant is not subject to contact with atmospheric air or other systems. The cooling system is associated solely with the air compressor for cooling its parts.

Abstract: A method for detecting conditions of interest in a distributed system. First, a condition of interest is formulated as a Boolean statement and stored at a condition detection component of the distributed system. The condition detection component then selectively receives events related to the condition of interest from a data collection component. Finally, the received events are combined and evaluated against the Boolean statement to determine if the condition is met. In one embodiment, the condition also includes a WITHIN element which filters out events received outside of a pre-specified time period.

Abstract: A method, a system, an apparatus, and a computer program product are presented for monitoring or managing a network using an object-oriented enterprise model. A set of objects are generated for the object-oriented enterprise model. An object is defined using an object-oriented language, and an object represents a device, a system, a collection of devices and/or systems, an executable program component, or a collection of executable program components within the network. An enterprise model is also defined using the object-oriented language such that the enterprise model is a set of related objects. Policies are created using the object-oriented language in which a policy contains one or more conditions and associated actions within the network. The policies can then be executed to perform monitoring and/or management tasks within the network.

Abstract: Methods that compensate for phase errors caused by path length variations in a radar system, and that compensate for relative phase errors in upconvertor and downconverter references employed in the radar system. One method samples a signal reflected from a duplexer through a receiver during the time the radar pulse is transmitted. The signal reflected from the duplexer is compared to a radar echo pulse on a single pulse basis. The phase of the sampled signal is subtracted from the phase of the received radar echo pulse reflected to determine the phase error. In a second method, multiple samples are collected during the time each radar pulse is transmitted. Samples of the signal reflected from the duplexer and the radar echo pulse are compared on a pulse to pulse basis. The phase differences are averaged across the pulse duration. The averaged phase differences are integrated on a pulse to pulse basis to determine the phase error.

Abstract: A coherent radar receiver that has pulse-to-pulse coherence using an unlocked voltage controlled oscillator, such as a Gunn voltage controlled oscillator. The present invention is a W-band, for example, bistatic receiver that uses a scanning sum channel antenna to scan the target, a downconverter for downconverting received alternating sum and difference pulse echoes from the bistatic illuminator to provide video signals, and processing circuits for processing the downconverted the video signals to precisely locate the null position on the target. A Fourier transform circuit, magnitude detector and a peak detection and centroid circuit are used to generate a voltage frequency control output signal that is applied to the voltage controlled oscillator or local oscillator that controls its frequency. An angle estimation algorithm is used that processes the video signals to locate the null offset from the center of a scan pattern generated by the antenna.

Abstract: A method wherein the scan rate of an active emitter is simultaneously estimated by a tracking receiver and a radar system and are then compared to correlate tracks generated by the tracking receiver and the radar system. The output produced by the present method provides for data that is more accurately indicative of the locations and identifications of emitters tracked by the tracking receiver and the radar system. More specifically, the method comprises the following steps. An active emitter having a scanning antenna is simultaneously tracked using a tracking receiver and a radar system. The location of the emitter is estimated using the tracking receiver by processing measurements of the electromagnetic signals generated by the emitter. The scan rate of the emitter is estimated using the tracking receiver by detecting strobing of the main lobe of the signals generated the emitter. The scan rate of the emitter is estimated using the radar system.

Abstract: A system and method that provides for all-weather precision guidance of conventional air-to-surface weapons. The system and method employs a coherent monopulse radar disposed on a launch platform and a noncoherent passive (receive only) radar disposed on the weapon. The synthetic aperture radar generates a synthetic aperture radar monopulse map of an area around the target. The radar is used designate the location of the target, and transmit a sequence of alternating sum and simultaneous azimuth and elevation difference patterns centered on the target. The weapon includes a guidance system and seeker that is responsive to guidance commands transmitted by the synthetic aperture radar. The guidance system and seeker receives reflections of the alternating sum and combined azimuth and elevation difference pattern from the target, and the sum pulse is used by the weapon to acquire and track the azimuth and elevation difference pattern null on the target to fly an optimum trajectory to the target.

Abstract: This invention is directed to a device and method for measuring carrier mlity and density in thin-film semiconductor materials such as those used in thin-film circuitry, particularly in high-frequency microwave devices. The device includes a microwave system in combination with a variable magnetic field in which the material to be measured is positioned at an E-field maximum in a shorted section of waveguide, which shorted section is in the magnetic field. The magnetic-field dependence of the reflected power is then monitored. The carrier mobility is derived from the value of the magnetic field at the point at which the microwave power reflected from the material falls to one-half of the reflected microwave power when the magnetic field value is zero. The electron density may be determined from the change in amplitude of the signal between zero magnetic field and high fields by proper calibration.
