Abstract
A system for determining optimum wake time is disclosed whereby the system comprising includes a receiver for receiving electroencephalogram (EEG) data. The system further includes a processor configured to generate at least one frequency band based on the EEG data received, wherein the processor is further configured to determine an optimum wake time based on a relative low point on the at least one frequency band. The system also includes an indicator configured to provide notification of the optimum wake time.
Claims17
A system for determining optimum wake time, the system comprising:
- a receiver for receiving and storing electroencephalogram (EEG) data and a user-specified sleep period;
- a processor configured to:
- determine a dominant oscillation of power within a frequency band based on past EEG data received;
- generate a power profile within the frequency band based on current EEG data received;
- and
- determine the optimum wake time using the dominant oscillation of power to predict one of a relative low point and relative high point on the power profile proximate in time to and before the end of the user-specified sleep period;
- and
- an alarm including an indicator configured to provide a stimulus to wake the user at the determined optimum wake time.
A system for determining optimum wake time, the system comprising:
- a receiver for receiving and storing electroencephalogram (EEG) data and a user-specified sleep period;
- a processor configured to:
- determine a dominant oscillation of power within a frequency band based on past EEG data received;
- generate a delta power rhythm associated with sleep depth based on current EEG data received;
- and
- determine the optimum wake time;
- wherein the optimum wake time is determined based on using the dominant oscillation of power to predict a relative low point on the curve of the delta power as plotted against sleep cycle time;
- wherein the relative low point occurs before the end of the user-specified sleep period;
- and
- wherein the relative low point corresponds to the optimum wake time resulting in minimal sleep inertia;
- and
- an alarm including an indicator configured to provide a stimulus to wake the user at the determined optimum wake time.
A method for determining optimum wake time, the method comprising:
- receiving and storing electroencephalogram (EEG) data via a receiver;
- determining, using a processor, a dominant oscillation of power within a frequency band based on past EEG data received;
- generating, using the processor, a power profile within the frequency band based on current EEG data received;
- determining, using the processor, the optimum wake time;
- wherein determining the optimum wake time is based on using the dominant oscillation of power to predict one of a relative low point and a relative high point on the power profile proximate in time to and before the end of a user-specified sleep period;
- and
- wherein one of the relative low point and the relative high point corresponds to the optimum wake time resulting in minimal sleep inertia;
- and
- providing, using an alarm, a stimulus to wake the user at the determined optimum wake time.
