摘要:
A method of increasing positional awareness of a pilot of an aircraft during a landing approach of the aircraft. First data from a navigational aid is received. The first data is analyzed to determine a first position of the aircraft at a predetermined time. Second data is received. The second data is independent of the first data. The second data is analyzed to determine a second position of the aircraft at the predetermined time. The first position of the aircraft and the second position of the aircraft are compared, and the pilot is alerted to a difference between the first position of the aircraft and the second position of the aircraft. The second data may be displayed in a form that is convenient for the pilot to view during landing.

A system for controlling an image displayed on a display unit of an aircraft is shown and described. The system includes an enhanced vision system that detects elements of an approach lighting system for display on the display unit. The system also includes a synthetic vision system that uses a database of navigation information and a determined aircraft location to generate synthetic display elements representing the approach lighting system. Display electronics of the system cause the detected elements from the enhanced vision system to be simultaneously displayed on the display unit within a same scene as the generated synthetic display elements from the synthetic vision system. Advantageously, the simultaneous display allows a pilot viewing the display unit to check for whether information provided by the enhanced vision system matches information provided by the synthetic vision system.

A method for monitoring inactive pixels in a scene imaging system may include determining a location of at least one inactive pixel in a focal plane array. The method may include sensing an environment image based upon a surrounding environment of an aircraft. The method may include generating an image associated with the environment image. The method may include evaluating a location for one or more inactive pixels in the generated image in comparison to a location for the at least one inactive pixel in the focal plane array. The method may include determining whether a fault exists in image generation or image display based upon the evaluation.

An apparatus provides a virtual display in an environment for various applications including avionic, naval, military, remote control, medical and other applications. The apparatus can be a near eye display, such as, a head up display (HUD) or head worn display (e.g., helmet mounted display (HMD), glasses-based, goggle-based, visor-based, etc.). The near eye display can include a combiner for providing one or more of: an image for a failed display, an image between two or more head down displays, or an image to direct attention to warnings or locations in the field-of-view of the combiner.

A head worn display system (e.g., helmet mounted (HMD) display system, and an eye wear mounted display system,) can include a combiner, a head position sensor and a computer. The computer provides symbology in response to first sensor input values associated with the head position. The symbology can be conformal with a real world scene. A monitoring system includes a redundant head position sensor for providing second sensor input values associated with head position. The computer monitors for positional accuracy of the symbology by comparing symbology calculated using the first and second input sensor values or by using an inverse function to compare sensor values.

An apparatus provides a virtual display in an environment for various applications including avionic, naval, military, remote control, medical and other applications. The apparatus can be a head up display (HUD) or head worn display (e.g., helmet mounted display (HMD) and can include image sources disposed at a respective image source position, and a combiner detached from the image sources. The combiner is movable to a respective combiner position for receiving light from a respective image source of the image sources. The combiner provides an image from the respective image source to a user.

A scene imaging system (SIS) integrity monitor for monitoring the required operation of an imaging sensor of an SIS. The SIS is of a type including: i) an imaging sensor, ii) an imaging system processor, and iii) an imaging system display. The SIS integrity monitor includes a signal emitter assembly for receiving emitter drive signals from an imaging system processor and directing a monitoring image into the active field of view of an imaging sensor for sensed image generation. The generated image is provided to the imaging system processor for analysis. The imaging system processor evaluates the location and modulation state of the generated image to determine if faults exist in the image generation or image display paths.

A method or system can be used with an aircraft or other vehicle. The system can include or the method can use a waveguide disposed above and below a top surface of a glare shield. The waveguide can be part of a head up display (HUD). The waveguide can be disposed to cover at least part of the head down display to provide an integrated display.

The speed dependent variable display system for a computer-implemented moving-map vehicle display system includes a data conversion module for converting a vehicle speed input signal to a distance range value; and, an application module for utilizing the distance range value, vehicle position information, vehicle direction of movement information, and input geographical information to provide scaled output geographical information. The scaled output geographical information is utilized to provide a situational awareness display which is optimized in accordance with the vehicle's position, direction of movement and speed. A display apparatus receives the scaled output geographical information to provide an optimized situational awareness display for a moving-map vehicle display system.
摘要:
The embodiments disclosed herein present novel and non-trivial system, module, and method for creating a variable FOV image presented on a HUD combiner unit. A processor receives navigation system data and data associated with eye position. A variable FOV image data set representative of navigation symbology is generated, where the image data set is determined by applying the navigation system and eye position data to an adaptive FOV function, where the function correlates eye position to an FOV image. The image data set is presented to a HUD system where an image represented in the image data set is displayed on a combiner unit, whereby the image FOV correlates to eye position. Furthermore, the processor may receive terrain data and generate a variable FOV image data set inclusive of data representative of a three-dimensional perspective scene outside an aircraft.
