Variably transmittive, electronically-controlled eyewear
First Claim
Patent Images
1. A system for selectively obscuring a user'"'"'s vision, the system comprising:
- a head position detection element for detecting a position of the user'"'"'s head;
eyewear having variably transmittive lenses; and
a controller configured to receive user head position information from the head position detection element comprising information regarding an up and down position of the user'"'"'s head relative to a predetermined point in space in front of the user and further configured to control the transmittivity of the lenses based on the user head position information by varying an electrical signal applied to the lenses, wherein the controller is configured to reduce the transmittivity to darken the lenses and thereby obscure the user'"'"'s vision when the user'"'"'s up and down head position is above the predetermined point in space, and wherein the controller is configured to increase the transmittivity to lighten the lenses and thereby not obscure the user'"'"'s vision when the user'"'"'s up and down head position is below the predetermined point in space.

Abstract
A system and method for flight training and evaluation of pilots comprises electronically activated vision restriction glasses that detect the pilot'"'"'s head position and automatically darken and restrict the pilot'"'"'s ability to see through the front and side windscreens when the pilot-in-training attempts to see out the windscreen. Thus, the pilot-in-training sees only within the aircraft cockpit, forcing him or her to fly by instruments in the most restricted operational mode.

7. A system for selectively obscuring a user'"'"'s vision, the system comprising:
-
a head position detection element for detecting a position of the user'"'"'s head; eyewear having variably transmittive lenses; and a controller configured to receive user head position information from the head position detection element comprising information regarding a left and right position of the user'"'"'s head relative to a predetermined point in space in front of the user and further configured to control the transmittivity of the lenses based on the user head position information by varying an electrical signal applied to the lenses, wherein the controller is configured to reduce the transmittivity to darken the lenses and thereby obscure the user'"'"'s vision when the user'"'"'s left and right head position is more than a predetermined distance from the predetermined point in space. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system for selectively obscuring a user'"'"'s vision, the system comprising:
-
a head position detection element for detecting a position of the users head, wherein the head position detection element comprises three near-infrared light emitting diodes, wherein one light emitting diode is mounted in front of the user to detect an up and down position of the user'"'"'s head and one light emitting diode is mounted on each side of the user to detect a left and right position of the user'"'"'s head and further comprises an associated collimated detector mounted on the user'"'"'s head; eyewear having variably transmittive lenses; and a controller configured to receive user head position information from the head position detection element comprising information regarding an up and down position of the user'"'"'s head relative to a predetermined point in space in front of the user and further configured to control the transmittivity of the lenses based on the user head position information by varying an electrical signal applied to the lenses. - View Dependent Claims (14, 15, 16, 17)

18. A system for selectively obscuring a user'"'"'s vision, the system comprising:
-
a head position detection element for detecting a position of the user'"'"'s head; eyewear having variably transmittive lenses; and a controller configured to receive user head position information from the head position detection element comprising information regarding an up and down position of the user'"'"'s head relative to a predetermined point in space in front of the user and further configured to control the transmittivity of the lenses based on user head position information by varying an electrical signal applied to the lenses, wherein the system is further configured to receive aircraft altitude information and wherein the system is configured to increase the transmittivity to lighten the lenses and thereby not obscure the user'"'"'s vision when the aircraft altitude information indicates that the aircraft is below a predetermined altitude. - View Dependent Claims (19, 20, 21)
