US10258808

1. A method of dynamically adjusting a circadian rhythm of an observer via a user device that includes control circuitry and an associated memory, the method comprising: (5) (3)

identifying one or more future events of the observer to precondition for, defined as identified future events;

determining a preconditioning schedule for at least one of the identified future events, including identifying a circadian shift needed to the circadian rhythm of the observer for the at least one identified future event,

determining a timeframe for preconditioning,

determining a per-day shift needed based upon the identified circadian shift needed and the determined timeframe, and

determining if the needed per-day shift exceeds a threshold,

upon a determination that the per-day shift exceeds the threshold, setting the preconditioning schedule responsive to the determination; and

operating the light source to emit light based upon the preconditioning schedule.

2. The method of claim 1 wherein identifying one or more future events includes determining a time zone within which the future event will occur. (0)

3. The method of claim 1 wherein identifying one or more future events includes: (0) (2)

4. The method of claim 1 further comprising: (0) (3)

5. The method of claim 1 wherein, upon a determination that the per-day shift exceeds the threshold, further performing: (1) (3)

7. The method of claim 1 further comprising: (1) (2)

monitoring a sleep cycle of the observer; and

implementing changes to the preconditioning schedule responsive to the sleep cycle of the observer.

8. The method of claim 7 wherein the step of monitoring a sleep cycle of the observer comprises: (1) (4)

determining if the observer is asleep;

recording signals from a sleep sensor;

identifying and recording an indication of low quality sleep from the signals received from the sleep sensor; and

determining changes to the preconditioning schedule responsive to the indication of the low quality sleep.

9. The method of claim 8 wherein the sleep sensor is at least one of an optical motion detector and an acceleration detector. (0)

10. A method of dynamically adjusting a circadian rhythm of an observer via a user device that includes a light source, control circuitry and an associated memory, the method comprising: (3) (3)

identifying a future event of the observer to precondition for, defined as an identified future event;

determining, using the control circuitry and associated memory of the user device, a preconditioning schedule responsive to the identified future event, by identifying a circadian shift needed, to the circadian rhythm of the observer, for the identified future event,

determining a magnitude of the identified circadian shift and a related magnitude of a per-day shift needed for the identified future event, and

determining if the magnitude of the per-day shift exceeds a threshold, and selecting the preconditioning schedule based thereon; and

operating the light source to emit light based upon the preconditioning schedule.

11. The method of claim 10 wherein identifying the future event includes determining a time zone within which the future event will occur. (0)

12. The method of claim 10 wherein identifying the future event includes: (0) (2)

13. The method of claim 10 wherein, upon a determination that the threshold exceeds the maximum allowed per-day shift, further performing: (1) (3)

15. A system for dynamically adjusting a circadian rhythm of an observer, the system comprising: (4) (3)

a user device comprising control circuitry and associated memory; and

a light source configured for communication with the control circuitry;

wherein the control circuitry is configured to identify one or more future events of the observer to precondition for, defined as identified future events,

determine a preconditioning schedule responsive to the identified future event, by identifying a circadian shift needed, to the circadian rhythm of the observer, for the identified future event,

determining a magnitude of the circadian shift and a related magnitude of a per-day shift needed for the identified future event, and

determining if the magnitude of the per-day shift exceeds a threshold, and selecting the preconditioning schedule based thereon, and

control the light source to emit light based upon the preconditioning schedule.

16. The system of claim 15 wherein the user device further comprises a communication device configured for communication with the control circuitry and configured to communicate across a network; and wherein the communication device is configured to access a calendar and identify future events associated with the observer via the network. (0)

17. The system of claim 15 wherein the control circuitry is further configured to: (0) (2)

18. The system of claim 15 wherein, upon a determination that the per-day shift exceeds the threshold, the control circuitry is further configured to: (0) (3)

19. The system of claim 15 further comprising a sleep sensor configured to, in combination with the control circuitry, monitor a sleep cycle of the observer; wherein the control circuitry is further configured to implement changes to the preconditioning schedule responsive to the sleep cycle of the observer.
