摘要:
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.

An apparatus monitors position for an aircraft. The aircraft includes a display, a position system, a vision system and a database comprising terrain data associated with an environment at a location of the aircraft. The apparatus includes a monitoring processor configured to perform character recognition or structure recognition on the image data to identify a structure or a character in the image data, correlate a position of the structure or character in the environment using a position from the position system and the terrain data, and cause the display to provide a confirmation in response to the position of the structure or character in the terrain data matches the position of the structure or character in the image data.

A present novel and non-trivial system, apparatus, and method is disclosed for presenting a flight director-dependent highway in the sky (“HITS”) pathway on an aircraft display unit. A processor receives flight plan data and flight director data, generates HITS data set representative of a flight director-dependent HITS pathway using flight plan data and flight director data, and provides the HITS data set to a display system for presentation of the flight director-dependent HITS pathway on a tactical display unit. Flight plan data provided to the processor may comprise of data sourced by a navigation system or HITS pathway data generated independently of flight director data. When presented on a tactical display unit, the flight director-dependent HITS pathway may be depicted with the flight director, where the proximal end of the HITS pathway aligns with the flight director.

Present novel and non-trivial systems and methods for positioning a heading-based image within a track-based image and for generating steering commands for a forward-looking image capture device of an enhanced vision system (“EVS”). The positioning system is comprised of a source of navigation data, a source of first image data representative of a track-based image, a source of second image data representative of a heading-based image, and an avionics system processor (“ASP”) configured to receive the navigation data, the first image data, and the second image data, determine image positioning data, and merge the first image data with the second image data as a function of the image positioning data. The steering commands generating system is comprised of a source of navigation data, the ASP configured to generate steering command data commensurate to a wind correction angle, and the EVS configured to receive the steering data.

The present examples provide circuits, systems, processes, and the like for providing precision course guidance, typically for improved positive course guidance below published minimum descent altitude or decision altitude, including just in time calculations of obstacle free flight paths. The calculated flight path may be presented in the context of a synthetic scene of the environment surrounding the aircraft. To provide precision course guidance, exemplary avionics systems, processes and the like, as described below may be utilized.

The present invention is a flight deck system for promoting accurate navigation of an aircraft. The system includes a memory configured for storing position information for the aircraft. The system further includes a processor which is configured for being communicatively coupled with the memory, the processor also being configured for receiving the aircraft position information stored in the memory. The system also includes a display which is configured for being communicatively coupled with the processor. The display is further configured for displaying a scaled indicator, the scaled indicator having been output to the display by the processor, the scaled indicator being based upon the received aircraft position information. The scaled indicator includes: a current position indicator for indicating an estimated current position of the aircraft, a desired position indicator for indicating a desired navigational position for the aircraft, and an allowable Flight Technical Error (FTE) indicator for indicating allowable Flight Technical Error (FTE) for the aircraft. Further, the current position indicator, the desired position indicator, and the FTE indicator are suitable for use by a pilot of the aircraft in maintaining the aircraft within established navigational boundaries.

An avionics display is disclosed. A synthetic rendering of terrain is created using stored terrain data. A horizon line is overlaid upon the synthetic rendering of terrain. The horizon line represents zero degrees pitch attitude in a direction of travel of an aircraft in which the avionics display is installed. The horizon line is configured to move in response to attitude-changing movement of the aircraft. An attitude cue is overlaid upon the synthetic rendering of terrain and depicted on first and second sides of the horizon line such that the synthetic rendering of terrain remains substantially visible. The attitude cue has a first appearance on the first side of the horizon line and a second appearance on the second side of the horizon line. The first appearance is visually contrasted from the second appearance.

An information magnification system for providing enhanced display information for a display system for a vehicle. The display system is of a type that includes a first display and a second display. The information magnification system includes a user interface for providing the capability for a user to select a magnification zone of interest on the first display of the vehicle. An information magnification electronics subsystem is associated with the user interface and with the first and second displays to enable the selected magnification zone to be presented on the second display appearing to be behind the physical surface of the second display at a selected distance, thus providing the capability for the user to maintain a far field of focus.
