High intensity light source blocking system and method
First Claim
1. A laser light blocking system for a vehicle operated by at least one crew member within a crew member cockpit, the system including:
- an eye-position detection system that outputs a crew member eye-position relative to the crew member cockpit;
a transparent dynamic-darkening display covering at least one window in the crew member cockpit;
a scene imager system configured to detect a presence of a laser light from a laser device and an emanation direction of the laser light relative to the crew member cockpit, the scene imager system comprising a plurality of one of photo-detectors and spectral intensity detectors on a portion of the vehicle exterior to the crew member cockpit and within the interior of the crew member cockpit;
a computing device connected to the eye-position detection system, the transparent dynamic-darkening display and the scene imager system, the computing device controlling the darkening of at least a portion of the dynamic-darkening display upon the occurrence of;
the laser light having an intensity value equal to or greater than a predetermined threshold; and
the crew member eye-position being subject to at least one of at least a direct portion of the laser light, or a substantial reflection of at least a portion of the laser light reflected from a surface within the crew member cockpit, a laser light direction calculated relative to the crew member cockpit based on a difference in received light intensity signals in at least two of the plurality of one of photo-detectors and spectral intensity detectors based upon low-level scattering in one ofthe air surrounding aircraft crew member cockpit, andthe crew member cockpit.

Abstract
A high intensity light source blocking system for a vehicle operated by a crew member within a cockpit includes an crew member position or eye-position detection system, a transparent dynamic-darkening display covering a window in the crew member cockpit, and a scene imager configured to detect a presence of a high intensity light source and an emanation direction relative to the crew member cockpit. A computing device is connected to the position or eye-position detection system, the transparent dynamic-darkening display and the scene imager, and controls the darkening of a portion of the dynamic-darkening display upon the occurrence of either the high intensity light source having an intensity value equal to or greater than a predetermined threshold, or the crew member position or eye-position being subject to either a direct portion of the high intensity light source or a substantial reflection thereof off a surface within the crew member cockpit.

15. A method that dynamically darkens an active window canopy of a crew member cockpit of an aircraft, the method comprising:
-
detecting a laser light from a laser device impinging on an active window canopy of a crew member cockpit; darkening the entire active window canopy based on detecting the laser light and determining whether the laser light is above an intensity threshold; configuring a plurality of one of photo-detectors and spectral intensity detectors on a portion of the aircraft exterior to the crew member cockpit and within the interior of the crew member cockpit; calculating a laser light direction relative to the crew member cockpit based on a difference in received light intensity signals in at least two of the plurality of one of photo-detectors and spectral intensity detectors based upon low-level scattering in one of the air surrounding aircraft crew member cockpit, and the crew member cockpit; and making the active window canopy transparent while darkening only a portion of the active window canopy at a first location on the active window canopy based upon determining the direction of the laser light and determining a relative position of at least one crew member in the crew member cockpit. - View Dependent Claims (16, 17, 18, 19, 20, 21)
