Patent number: 6448921Abstract: An electronic warfare radio receiver of the monobit type wherein the signal processing circuitry, including a bandpass filter array, analog to digital converter circuit and Fourier transformation circuit, are located in a plurality of parallel-disposed but isolated receiver channels. The parallel disposed receiver channels limit interference between received signals and enable the customary processing of two simultaneous input signals of differing signal strength in each receiver channel; this increases the number of simultaneous input signals processable by a factor equaling the number of receiver channels used. Single chip embodiment of the receiver is disclosed thereby tending to compensate for the added complexity of the channelized processing. Signals falling in digital filter overlap regions are addressed by the invention.Type: GrantFiled: July 30, 2001Date of Patent: September 10, 2002Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: James B.

Patent number: 6446904Abstract: An aircraft weapons bay high frequency acoustic suppression apparatus is disclosed. The apparatus includes an extendable spoiler retractably received within an aircraft weapons bay. An injector unit is received within the spoiler for injecting high frequency pulses of pressurized gas into the airstream. The injector unit includes a resonance tube in outlet fluid communication with an nozzle. The pulsating output of the resonance tube perturbs the flow of pressurized gas in the nozzle, effectively breaking it up into discrete slugs or pulses which then exit the nozzle and enter the airstream. The high frequency perturbation of the airflow across the weapons bay, created by the aircraft weapons bay high frequency acoustic suppression apparatus of the present invention effectively suppresses undesirable acoustic resonance within the open weapons bay.Type: GrantFiled: October 5, 2001Date of Patent: September 10, 2002Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Michael J. Stanek

Patent number: 6443239Abstract: A pneumatic rotary tool including a housing and an output shaft projecting from the housing for transmitting torque to an object. An air motor drives rotation of the output shaft in the forward and reverse directions. Air passages extend from an air inlet to the motor for delivering pressurized air to the motor. A spring biases the lower portion of a valve within the air passage in a closed position, to restrict the flow of air through the air passage. The upper portion of the valve comprises a stem. When an operator squeezes a trigger on the pneumatic rotary tool, a deflector connected to the trigger deflects the stem to a first angularly deflected position, the valve thereby allows a relatively low rate of air flow to the motor for low-speed operation thereof. As the operator continues to squeeze the trigger, the stem is deflected to a second angularly deflected position, allowing a relatively high rate of air flow to the motor for high-speed operation thereof.Type: GrantFiled: February 29, 2000Date of Patent: September 3, 2002Assignee: S.P. Air Kabusiki KaishaInventor: Osamu Izumisawa

Patent number: 6445152Abstract: Method of controlling a motorized door by offloading the burden to a separate motion control processor. The method includes generating, in a central processor for the door, one or more signals indicative of a predetermined door speed profile for a stroke of the door. The predetermined door speed profile provides an ideal velocity versus an elapsed time since a beginning of the stroke. The signals are communicated to a motion control processor and the motion control processor also receives door position signals from a position encoder. The motion control processor generates signals indicative of the velocity of the door based on the door position signals and it generates error signals based on discrepancies between the velocity of the door and the ideal velocity. It generates motor control signals based on the error signals and the motor control signals are communicated to the motor of the door.Type: GrantFiled: November 24, 1999Date of Patent: September 3, 2002Assignee: Westinghouse Air Brake Co.Inventor: Philip J.
