Abstract: A method of generating differentially-corrected smoothed pseudorange data in a differential global positioning system (DGPS) includes generating, at a base station, non-mode specific pseudorange and carrier phase correction data. The non-mode specific pseudorange and carrier phase correction data is then provided to a remote receiver. At the remote receiver, one of a plurality of specific smoothing modes of operation is selected for use in generating differentially-corrected smoothed pseudorange and carrier phase data. The differentially-corrected smoothed pseudorange and carrier phase data is then generated by the remote receiver using the selected one of the plurality of specific smoothing modes of operation, and as a function of the non-mode specific pseudorange and carrier phase correction data received from the base station.

Abstract: The present invention is an improved antenna system. In an embodiment of the invention, the antenna system of the present invention may be a dielectric resonator antenna which may include a dielectric cap that may surround a plurality of feed probes. The antenna system may be suitable for coupling to a projectile whereby the dielectric cap forms a front end, or nose, of the projectile. The plurality of feed probes may produce orthogonal vector components of a field to provide circular polarization. Additionally, feed probes may be optimally spaced within the dielectric cap to ensure the phase center of the antenna system may be co-located with a platform axis of rotation whereby no carrier phase rollup compensation may be required.

Abstract: A head up display system for a vehicle includes an image source and an optical combiner which reflects the projected image from the image source toward an observer for observation. The optical combiner is positioned so that the observer, in a line of sight, sees both a visual exterior view of an outside scene through the combiner and the projected image in the combiner. In disclosed embodiments, the optical combiner comprises wedge lenses.

Abstract: A method of sealing an Organic Light-Emitting Diode (OLED) assembly is disclosed. A dry film adhesive is applied to a capping layer. An OLED assembly is placed in a cavity of a fixture. The capping layer is positioned in the cavity of the fixture such that a first edge of the capping layer contacts the OLED assembly and a second edge of the capping layer is separate from the OLED assembly. Atmospheric pressure is reduced between the capping layer and the OLED assembly. The second edge of the capping layer is dropped such that the second edge of the capping layer is adjacent the OLED assembly.

Abstract: A method of reducing luminance decay of emissive elements in a matrix addressed emissive display device includes generating control data corresponding to a static image to be displayed on a matrix of individually addressable emissive display elements. Drive signals are generated as a function of the control data, and are provided to the matrix to thereby energize the corresponding emissive display elements of the matrix in order to display the static image on the matrix. The control data are altered substantially continuously in order to substantially continuously move the static image on the matrix.

Abstract: A head-up display (HUD) is disclosed. The HUD is provided on board an aircraft. The HUD comprises a projector and a combiner. The combiner enables viewing of the world outside of the combiner and also allows viewing of information provided from the projector. A computer is coupled to the projector and provides airport runway and taxiway symbols conformally mapped onto the combiner. Also provided on the combiner is a mapping of hold lines onto the combiner.

Abstract: An elevator variable feel unit for aircraft pilot control. The variable feel unit has a single cam and a roller unit. The cam attaches by a spline to the input shaft and input crank of the feel unit. The input crank, connected to the control column torque tube, turns the shaft and the cam. A cam follower arm assembly has a roller that causes a cam follower arm to pivot as the cam is pivoted due to movement of the control column. Two base feel centering springs between the cam follower arm and a fixed point to keep the roller on the cam, and provide the base feel force and a centering function. In a base feel position, the preload on the base feel spring keeps the variable feel unit in a detent position. The variable feel spring has a minimum preload and does not add to the feel at low airspeed. When the control column is moved, the movement causes an increase in the extension of the base feel springs, thus increasing the feel forces at the column.

Abstract: A method of detecting a windshear hazard on aircraft is disclosed. The method includes determining a first wind velocity of the aircraft at the location of the aircraft using a wind velocity detector. The method also includes determining a second wind velocity at a distance ahead of the aircraft using a forward-looking wind velocity detection system onboard the aircraft. Further, the method comprises determining the wind velocity gradient over the distance and determining whether windshear hazard exists for the aircraft.

Abstract: A designated function or “golden” slot for implementing and managing re-configurable SDR modules is provided. In an embodiment, the slot includes at least one radio frequency (RF) front end for providing an interface with at least one antenna. In addition, the slot may include at least one slot modem coupled to the RF front end for implementing at least one designated function and at least one input/output (I/O) module coupled to the slot modem. The designated function or “golden” slot is capable of implementing and managing the at least one designated function in a re-configurable module during standard and emergency operations.
