Abstract

An apparatus and method for predicting cognitive performance of an individual based on factors including sleep history and the time of day. The method facilitates the creation of predicted cognitive performance curves that allow an individual to set his/her sleep times to produce higher levels of cognitive performance. The method also facilitates the reconstruction of past cognitive performance levels based on sleep history.

Claims

1. An apparatus for predicting cognitive performance comprising:

an input connection,

a data analyzer connected to said input connection to select a calculation function responsive to the received data,

a calculator connected to said data analyzer to calculate a cognitive performance capacity using the calculation function,

a first memory including modulation data, and

a modulator connected to said first memory and said calculator to modulate the cognitive performance capacity with the modulation data to generate a predicted cognitive performance.

2. The apparatus of claim 1, further comprising a display connected to said modulator.

3. The apparatus of claim 1, further comprising a communication port connected to said modulator, said communication port relays the predicted cognitive performance to an external device.

4. The apparatus of claim 1, further comprising a second memory connected to said calculator and said modulator, said second memory stores the cognitive performance capacity produced by said calculator.

5. The apparatus of claim 4, wherein said first memory and said second memory are integrally formed as one memory.

6. The apparatus of claim 4, wherein said second memory is a first-in-first-out memory.

7. The apparatus of claim 1, wherein the modulation data represents time of day variations over a 24-hour period.

8. The apparatus of claim 1, wherein said data analyzer includes a sleep scoring system.

9. The apparatus of claim 1, wherein said input connection is a telemetric receiver.

10. The apparatus of claim 1, wherein said input connection is a keyboard.

11. The apparatus of claim 1, further comprising a first-in-first-out memory connected to said modulator, said first-in-first-out memory stores the predicted cognitive performance.

12. The apparatus of claim 1, further comprising a second memory connected to said modulator.

13. The apparatus of claim 12, wherein said first memory and said second memory are integrally formed as one memory.

14. The apparatus of claim 1, wherein said modulator matches the data in said second memory to the modulation data based on time sequencing.

15. The apparatus of claim 1, wherein said input connection includes a telemetric receiver.

16. The apparatus of claim 1, wherein said input connection includes a keyboard.

17. The apparatus of claim 1, wherein the modulation data represents a curve having a period of 24 hours such that the curve includes a first sinusoidal curve having a 24-hour period and a second sinusoidal curve having a 12-hour period.
