Abstract: A system and method for calibrating stereoscopic cameras in an aircraft utilizes a plurality of lasers aimed at a desired convergence point, such as at a point on a runway or other ground facility or projection surface. Each of the stereoscopic cameras are adjusted in terms of pitch, yaw, and roll to align the convergence point in each camera. Misalignments are iteratively corrected, as required. An alignment crosshair is applied, physically or electronically, and the convergence point aligned to the alignment crosshair.

Abstract: A system and method for computing and displaying a fuel optimal idle deceleration start point which minimizes the overall auto throttle movement keeping the throttle at idle detent throughout the maneuver thus minimizing the fuel burn and stress on engine. The need for speed brakes deployment is also reduced because the deceleration distance length is accordingly adjusted based on current parameters. The accurate solution takes into account the current condition such as aircraft weight, altitude and speed and environmental parameters such as wind and temperature. The computed deceleration start point is displayed on map/navigation and vertical display for enhanced flight crew awareness.

Abstract: A system for interactive heads-up display (HUD) and control of traffic targets is disclosed. In embodiments, the HUD receives and decodes traffic information from onboard surveillance systems to identify proximate aircraft within a threshold range and the relative positions of each aircraft. The HUD arranges the proximate aircraft into an ordered sequence based on distance from ownship or other priority criteria. When the HUD is active, interactive symbols are displayed at the relative positions of the proximate aircraft (e.g., or at the edges of the display for air traffic within range but outside the HUD field of view). A heads-up controller is operable by the pilot and allows the pilot to highlight each interactive symbol in sequence with a displayable cursor, selecting and designating the associated proximate aircraft for spacing or traffic applications without taking pilot focus off the HUD.

Abstract: A voice-activated system for interactive heads-up display (HUD) and control of traffic targets is disclosed. In embodiments, the HUD receives and decodes traffic information from onboard surveillance systems to identify proximate aircraft within a threshold range and the positions of each aircraft.

Voice commands allow the pilot to highlight, select, and designate traffic targets for visual separation or other traffic applications based on the locations of traffic targets or by verbally identifying specific traffic targets.

Abstract: A computationally efficient real-time photonic cyclic autocorrelation function (CAF) analysis device and method are disclosed. In embodiments, the CAF analyzer generates a photonic carrier which is converted into upper and lower comb signals (comprising a set of N tones) by upper and lower optical frequency comb generators (OFCG), the lower comb signal offset from the upper. An inbound radio frequency (RF) signal is received and modulates the upper and lower comb signals via amplitude modulation. An optical delay line (e.g., ring resonator) introduces a delay into the modulated lower comb signal. The upper and lower comb signals are demultiplexed into their modulated frequency component and sent to a bank of N coherent I/Q receivers, which generate a slice of the CAF for the received RF signal based on the selected delay.
