Abstract: A refueling system and method for use with a refueling tanker aircraft. The system and method involves the use of a camera system to provide imaging information concerning a receiver aircraft to the processor. The processor uses the imaging information to derive closure rate and distance information for the receiver aircraft as it approaches a refueling envelope prior to contact with a refueling boom. The processor also makes use of information from a look-up table to generate commands that are tailored to the specific type of aircraft being refueled. The commands are applied to a pilot's director lights display that generates visual commands or signals (e.g., “UP”, “DOWN”, “LEFT”, “RIGHT”) that assist the pilot of the receiver aircraft in guiding his/her aircraft toward and into the refueling envelope at a desired closure rate.

Abstract: Methods and apparatus for digitally enhancing images are disclosed. In one embodiment, a method includes performing a wavelet transformation process on an acquired image to provide a low pass spatial frequency. A dynamic range and a mixing value are then determined from the low pass spatial frequency, and the mixing value is applied to provide a transformed output image. The transformed output image is then reformatted to provide a mixed output image, and the mixed output image is subtracted from the acquired image to provide an enhanced image. In an alternate embodiment, a method includes analyzing an acquired image to provide a high sensitive low light image and a low sensitive high light image, and then summing the high sensitive low light image and the low sensitive high light image to create an enhanced image.

Abstract: A vision system and method for use on a refueling tanker to assist a boom operator in performing an airborne refueling operation on a receiver aircraft. The system includes a digital camera system, a sensor subsystem and a processing system that receives information from the sensor system and the camera system. The processing system includes video processing capability and a graphics generator that generates a two dimensional graphics symbology set that is displayed on a display terminal along with a real time image of the boom and the receiver aircraft. The graphics symbology set includes a plurality of graphic symbols that indicate the position of the refueling boom and the position of the receiver aircraft relative to a desired contact zone within which physical contact between the boom tip and a refueling receptacle on the receiver aircraft can be made. The graphics symbology set also makes use of various colors to indicate warning conditions to the boom operator.

Abstract: An apparatus and method is disclosed for increasing the light output of a stereoscopic three-dimensional display system by reducing the light losses typically present when using a conventional beam-combining half-mirror, i.e. a beam splitting device (BSD). The separate outputs of two LCD monitors are optically superimposed, one for the left eye and one for the right eye of a user, in order to produce a brighter stereoscopic three-dimensional display. By selecting angles of linear polarization for the rear and the side LCD monitors or other display devices, embodiments of the invention can achieve as much as 60/60 efficiency for the display pair, according to the Fresnel laws of reflection regarding polarization. This intensity increase can provide a viewer a significantly brighter picture and allow the installation environment of the stereoscopic display to maintain higher ambient lighting conditions.

Abstract: An in-flight refueling system, boom, and method are provided for extending the range of motion of an in-flight refueling boom carried by a first aircraft so as to facilitate an in-flight refueling operation between the first and the second aircraft. More specifically, in some embodiments the present invention provides a rotating device, operably engaged with at least one airfoil, and configured to substantially surround and rotate about the in-flight refueling boom such that the rotating device and the at least one airfoil operably engaged therewith, may be actuated so as to extend the range of motion of the in-flight refueling boom.

Abstract: An apparatus and method for detecting and correcting for physical misalignments of a pair of digital cameras creating a composite, three dimensional (3D) image of a target. The method involves using the distances from each of a pair of digital cameras to a target and determining correction offset values for one or the other of the images produced in the digital cameras to achieve pixel-to-pixel coincidence of the two images. The correction offset values are calculated and performed in real time and eliminate the need to physically remove a common platform on which the cameras are mounted from a mobile platform or other support structure, and to transport same to a laboratory environment for the needed calibration. Advantageously, the correction values are generated electronically and applied in real time as any misalignment between the cameras is sensed.

Abstract: An in-flight refueling system and method are provided to extend and retract an in-flight refueling device between a stowed position and an extended position relative to a tanker aircraft. The system and method of the present invention provide an induction device configured to extend and retract the in-flight refueling device such that the in-flight refueling system requires less maintenance and may be packaged in a compact, low-profile arrangement so that the in-flight refueling system may be carried by a variety of tanker aircraft in a variety of different configurations.

Abstract: A tanker aircraft refueling boom utilizes an upper boom tube that connects to an aircraft fuselage, a lower boom tube that connects to the upper refueling tube, and a removable flexible tube with a nozzle that is connected to the lower boom tube. The flexible tube is bendable to accommodate movement of the tanker aircraft relative to the receiver aircraft during refueling. The flexible tube is expandable to absorb shock loads due to the conservation of momentum of the fuel when the fuel is shut off during delivery. The expandable flexible tube eliminates shock loads in other areas of the refueling boom. A ruddevator is attached to the refueling boom to permit aerial control of the upper, lower and flexible tubes prior to and during refueling. The flexible tube is independently removable from the refueling boom to facilitate convenient and cost-effective maintenance.

Abstract: Apparatus and methods for covertly determining the rate of motion between a pixel-based imaging device and a target being viewed by the pixel-based imaging device. The method involves using the pixel-based imaging device to acquire a first and a second digital image of the target. The second digital image is acquired a time interval after the first digital image. The time interval and pixel counts for the pixel set within the first and the second digital image representing a particular portion of the target are then used to determine a rate of relative motion between the pixel-based imaging device and the target. Advantageously, the rate of relative motion is determined covertly such that the locations of the pixel-based imaging device and the target are not disclosed or broadcast to third parties.

Abstract: An in-flight refueling system, sensor system and method are provided for detecting and damping changes in the disposition of an elongate hose extending from a tanker aircraft during an in-flight refueling operation. The various embodiments provide a compact, lightweight, and low-profile sensor device that may be fitted to the elongate hose so as to detect oscillations in the elongate hose and transmit a signal to a hose retracting device carried by the tanker aircraft such that the hose retracting device retracts the elongate hose in response to the signal so as to counteract the occurrence of oscillations within the elongate hose. Thus, these embodiments may minimize the effect of oscillations in the elongate hose by selectively retracting the elongate hose in response to oscillations detected therein as it extends from the tanker aircraft during an in-flight refueling operation.
