US 2021/0260403 A1 · SYSTEM AND METHOD FOR STIMULATING ALERTNESS IN A SUBJECT

Abstract

The present invention relates to a system for stimulating alertness in a subject within an environment exposed to an ambient light having a fluctuating ambient light illuminance The system comprises an optical generator with a light source configured to generate a stimulating light having a stimulating light irradiance; and a driver coupled to the light source for controlling the stimulating light irradiance; an ambient light sensor configured to monitor the ambient light illuminance in real-time; and a controller operatively coupled to the optical generator and to the ambient light sensor to control the stimulating light irradiance in response to the ambient light illuminance monitored by the ambient light sensor, the controlling comprising capping the stimulating light irradiance to a maximal irradiance value based on the monitored ambient light illuminance. The present invention also relates to a method for stimulating alertness in a subject.

A system for stimulating alertness in a subject within an interior exposed to an ambient light having a fluctuating ambient light illuminance, the interior being provided with an ambient light sensor configured to monitor the ambient light illuminance within said interior in real-time, the system comprising:

an optical generator comprising:
one or more light sources configured to collectively generate a stimulating light having a stimulating light irradiance;
and
a driver coupled to the one or more light sources for controlling the stimulating light irradiance;
and
a controller operatively coupled to the optical generator and operatively couplable to the ambient light sensor of the interior to control the stimulating light irradiance in response to the ambient light illuminance monitored by the ambient light sensor, said controlling comprising capping the stimulating light irradiance to a maximal irradiance value based on the monitored ambient light illuminance.
