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.
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 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.
摘要:
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.

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.

Provided in one embodiment is a method of detecting a pulsing signal, comprising: detecting the pulsing signal using a first sensor device acquiring data at a first time interval; and detecting the pulsing signal using a second sensor device acquiring data at a second time interval; wherein the second time interval overlaps a portion of the first time interval.
摘要:
An enhanced vision system for an aircraft is disclosed. The invention includes a display apparatus having a display element positioned between the pilot and a scene. The display element permits the pilot to view the scene therethrough. A first sensor is mounted adjacent to the display element. The first sensor is configured to detect light having a first radiation spectrum emanating from a first portion of the scene. A second sensor is mounted upon the aircraft away from the display element. The second sensor is configured to detect light having a second radiation spectrum emanating from a second portion of the scene. The display element is configured to visually represent the detected light with the first radiation spectrum precisely conformal with the scene as viewed by the pilot. The display element is configured to visually represent the detected light with the second radiation spectrum substantially conformal with the scene as viewed by the pilot.
摘要:
A present novel and non-trivial system, device, and method for reducing image generating latency of an image presented on a display unit are disclosed. An image processing unit (“IPU”) may receive the image data set; receive (1) first navigation data of a first time from which second navigation data of the second time is determined or (2) second navigation data of a second time; receive third navigation data of the second time; compare the second navigation data with the third navigation data; and select a subset of the image data set in response to the comparison. Differences arising from the comparison, if any, may be used in determining the location and/or rotation of a cropping frame that selects the subset and forms a cropped image which is then provided to a display system, whereby the image represented in the subset is presented to the viewer.
