摘要： A mutual coupling neutralizer for neutralizing adverse mutual coupling between a pair of patch antennas for mobile communication system. The coupling neutralizer includes a first and second capacitor each having a first end and a second end, where the first ends are coupled to a respective patch antenna. The neutralizer further includes a high impedance transmission line connected to the second ends of the capacitors. The transmission line and capacitors are sized and configured to neutralize adverse mutual coupling between the pair of patch antennas over a predetermined frequency band. The neutralization of mutual coupling is achieved by extracting a signal present at one patch antenna and injecting the signal at the other patch antenna at a substantially equal amplitude and opposite in phase.

摘要： A dual band, stacked microstrip antenna produces circular polarization. A two-layer, 90° microstrip coupler is mounted to a hi-band patch and a lo-band patch and provides two inputs to the antenna to excite two orthogonal linearly polarized radiation patterns in quadrature. The coupler outputs are connected to the antenna by two conducting pins that connect directly to the groundplane of the lower patch. The coupler uses the hi-band patch as a groundplane and is transparent to the radiation from the antenna. An antenna input connector is connected to the coupler input by means of a coaxial line through the center of the antenna. The isolation port is terminated in a surface mounted 50-ohm resister to ground through a quarter wave length open transmission line.

摘要： A method and apparatus for in-flight refueling of unmanned aircraft includes a manned tanker aircraft having a refueling probe mounted thereon. The probe is extendable for increased visual reference. A drogue mounted on the distal end of a flexible refueling hose is trailed from the unmanned aircraft. The refueling hose is stored on a reel assembly mounted on the fuel tank of unmanned aircraft. The reel assembly is remotely actuated from the manned tanker to pay out the refueling hose. A homing system transmits signals from the manned aircraft guiding the drogue to the probe. Upon insertion of the probe into the drogue, automatic coupling occurs and the unmanned aircraft is refueled.

摘要： A mass data storage unit includes a plurality of first data storage modules for containing tape cassettes that form a mass information storage library, a data directory archive comprising a data storage medium for maintaining a directory of the information contained on each data storage module tape cassette, and data record/playback modules for receiving any selected tape cassette from any data storage module in the mass storage library, thus providing global access to the media. A plurality of interface computers are coupled to a plurality of host computers for receiving data and for generating request signals to access information stored on said tape cassette. A file directory is coupled to the interface computers and the data directory archive for receiving the request signals, locating in the data directory archive the address of the tape cassette containing the stored information and generating a data address location output signal for the tape cassette containing the stored information. A control computer is coupled to the file directory and the mass storage library for receiving the data address location output signal from the file directory and in response thereto generating a signal for causing the selected tape cassette in the data storage module containing the requested information to be loaded into a selected data record/playback unit. An input/output data channel couples the interface computer generating the access request signal to the selected data record/playback module for selectively reading the stored information from and writing data to the selected tape cassette.

摘要： A direct drive servo valve includes a valve housing (10) having a cylindrical bore (12) and a valve spool (28) mounted for movement in the bore for controlling fluid flow through said valve housing. The valve spool has a drive well (30) located in the spool transverse of its longitudinal axis. A motor secured to the valve housing includes a rotor (48) which is rotated in response to a drive signal applied to stator windings (46) of the motor. A shaft (50) attached to the rotor for rotation therewith includes a substantially spherical drive tip (76), the spherical tip positioned eccentrically to the longitudinal axis of the shaft and being close fitted into the drive well (30). In operation, as the shaft rotates through a given angular rotation, the spherical tip rotates in a circular path to provide linear displacement and rotational motion to the valve spool.
