Abstract
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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
88 words
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.
Claim 2
Independent Claim
88 words
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.
Claim 3
Dependent Claim
50 words
The method of claim 1 wherein said receiving said plurality of initial alertness data of said individual comprises receiving a plurality of data selected from the group consisting of age, home time zone, morning/evening tendency, sleep/wake diary data, currently acclimatized shift/sleep schedule, shift/duty times, and rules for probable sleep-wake pattern.
Claim 4
Dependent Claim
51 words
The method of claim 1 wherein said adjusting said initial alertness data based upon a plurality of predetermined alertness-modifying stimuli to which said individual is exposed comprises adjusting alertness-modifying stimuli selected from the group consisting of nap, caffeine ingestion, alcohol ingestion, sleep deprivation, sleep restriction, photostimulation, sleep phase, and bright light.
Claim 5
Dependent Claim
25 words
The method of claim 1 wherein said providing said predicted alertness level data in a humanly-sensible format consists of providing said data as printed output.
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein said providing said predicted alertness level data in a machine-readable format consists of providing said data as electronic impulses.
Claim 7
Independent Claim
110 words
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.
Claim 8
Independent Claim
110 words
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.
Claim 9
Dependent Claim
50 words
The method of claim 6 wherein said receiving said plurality of initial alertness data of said individual comprises receiving a plurality of data selected from the group consisting of age, home time zone, morning/evening tendency, sleep/wake diary data, currently acclimatized shift/sleep schedule, shift/duty times, and rules for probable sleep-wake pattern.
Claim 10
Dependent Claim
51 words
The method of claim 6 wherein said adjusting said initial alertness data based upon a plurality of predetermined alertness-modifying stimuli to which said individual is exposed comprises adjusting alertness-modifying stimuli selected from the group consisting of nap, caffeine ingestion, alcohol ingestion, sleep deprivation, sleep restriction, photostimulation, sleep phase, and bright light.
Claim 11
Dependent Claim
22 words
The method of claim 6 wherein said supplying said determination in a humanly-sensible format consists of supplying said determination as printed output.
Claim 12
Dependent Claim
22 words
The method of claim 6 wherein said supplying said determination in a machine-readable format consists of supplying said determination as electronic impulses.
Claim 13
Independent Claim
101 words
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.
Claim 14
Independent Claim
101 words
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.
Claim 15
Dependent Claim
50 words
The method of claim 11 wherein said receiving said plurality of initial alertness data of said individual comprises receiving a plurality of data selected from the group consisting of age, home time zone, morning/evening tendency, sleep/wake diary data, currently acclimatized shift/sleep schedule, shift/duty times, and rules for probable sleep-wake pattern.
Claim 16
Dependent Claim
51 words
The method of claim 11 wherein said adjusting said initial alertness data based upon a plurality of predetermined alertness-modifying stimuli to which said individual is exposed comprises adjusting alertness-modifying stimuli selected from the group consisting of nap, caffeine ingestion, alcohol ingestion, sleep deprivation, sleep restriction, photostimulation, sleep phase, and bright light.
