Embodiment Construction

[0016] As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. As used herein, the statement that two or more parts or components are "coupled" shall mean that the parts are joined together, directly or indirectly (i.e., through one or more intermediate parts or components) or run together whenever linking occurs. As used herein, "directly coupled" means that two elements are in direct contact with each other. As used herein, "fixedly coupled" or "fixed" means that two components are coupled so as to move as one while maintaining a constant orientation relative to each other. As used herein, the word "unitary" means that a component is created as a single piece or unit. That is, a component that includes pieces that are created separately and then coupled together as a unit is not a "unitary" component or body. As employed herein, the statement that two or more parts or components "engage" one another sh...

Abstract

Systems and methods to predict circadian phase of a subject use one or more sensors to track light exposure of the subject over a period and determine the current circadian phase. A prediction for future light exposure is used to predict a future circadian phase.

Description

technical field [0001] The present disclosure relates to systems and methods for predicting a circadian phase of a subject, and in particular to predicting future circadian phases using predictions of future exposures. Background technique [0002] The impact of radiation on a subject can be known to affect circadian rhythms and / or address poor light disorders. Typically, these treatments involve, for example, flashing light directly into the patient's eyes while the patient is awake, to relieve or treat low-light disorders, including, but not limited to, seasonal affective disorder (SAD); circadian rhythm sleep disorders; and shift work associated with, for example, jet lag. Disruption of circadian rhythm associated with work and / or other occupational conditions that can cause disruption of circadian rhythm. [0003] Various models can be used to calculate and / or estimate a subject's circadian phase. Typically, calculations and / or estimates are made based on exposure and / ...
