Method for predicting alertness and bio-compatibility of work schedule of an individual
First Claim
1. A method of predicting the alertness of an individual, said method comprising the steps of receiving a plurality of initial alertness data of said individual, adjusting said initial alertness data based upon a plurality of predetermined alertness-modifying stimuli to which said individual is exposed, computing data representative of the predicted alertness level for said individual based upon said adjusting of said initial alertness data, and providing said predicted alertness level data in a processable format, said processable format selected from the group consisting of humanly-sensible and machine-readable formats.

Abstract
A method enables the prediction of the likely alertness level of an individual at a given point in time based upon the analysis of certain biological and other parameters associated with the individual subject including, circadian phase of the biological clock, accumulated acute or chronic sleep deprivation, shift commencement and termination time, time of last sleep, environmental light, etc. Among other advantages, the method facilitates the creation of bio-compatible schedules for shift workers by providing an accurate model of the likely alertness level of the individual on a specific schedule.

- 1. A method of predicting the alertness of an individual, said method comprising the steps of receiving a plurality of initial alertness data of said individual, adjusting said initial alertness data based upon a plurality of predetermined alertness-modifying stimuli to which said individual is exposed, computing data representative of the predicted alertness level for said individual based upon said adjusting of said initial alertness data, and providing said predicted alertness level data in a processable format, said processable format selected from the group consisting of humanly-sensible and machine-readable formats.
- 6. A method for determining the bio-compatibility of a given work schedule for an individual, said method comprising the steps of receiving a plurality of initial alertness data of said individual, adjusting said initial alertness data based upon a plurality of predetermined alertness-modifying stimuli to which said individual is exposed, computing modified alertness data for said individual based upon said adjustments to said initial alertness data, determining the bio-compatibility of said work schedule by comparing said modified alertness data during said proposed work schedule to a minimum acceptable alertness level, and supplying said determination in a processable format, said processable format selected from the group consisting of humanly-sensible and machine-readable formats.
- 11. The method for selecting a bio-compatible work schedule for an individual, said method comprising the steps of receiving initial alertness data of said individual, receiving at least one proposed schedule for said individual, adjusting said initial alertness data based upon a plurality of predetermined alertness-modifying stimuli to which said individual is exposed, computing modified alertness data for said individual based upon said adjusting of said initial alertness data, selecting said bio-compatible work schedule based on said modified alertness data, and supplying said selection determination in a processable format, said processable format selected from the group consisting of humanly-sensible and machine-readable formats.
