Apparatus and method for monitoring the condition of a night vision device user with non-visible light |
摘要 |
A system for monitoring the condition of an optical device user with non-visible light includes a non-visible light source that is positioned to direct a beam of non-visible light onto an eye of the optical device user. A non-visible light sensor is positioned to receive non-visible light that is reflected off of the eye and is configured to generate a signal corresponding to either a level or an intensity of the received non-visible light. A processor is connected to the light sensor, and is configured to determine a condition of the eye including whether the eye is either not moving, closed without blinking or open without blinking for more than a pre-determined amount of time based upon signals received from the light sensor. Also disclosed herein is a method for monitoring the condition of an optical device user with non-visible light. |

1. A system for monitoring the condition of an optical device user with non-visible light, comprising:
a non-visible light source that is positioned to direct a beam of non-visible light onto an eye of the optical device user; a non-visible light sensor that is positioned to receive non-visible light that is reflected off of the eye and is configured to generate a signal corresponding to either a level or an intensity of the received non-visible light; and a processor that is connected to the light sensor, and is configured to determine a condition of the eye including whether the eye is either not moving, closed without blinking or open without blinking for more than a pre-determined amount of time based upon signals received from the light sensor. |
