Smart Pillow
A pillow is provided which is configured with sensors in communication with a controller having a computing component and software running in electronic memory. Using input data streams from the sensors to the controller, the software running on the computing component can ascertain a current sleep level of a user as being in a REM cycle or non REM cycle, The controller is configured to override a user set alarm time on an alarm, with a new activation time should it be determined the user will be in a REM cycle at the user chosen time for the alarm.
1 . A pillow apparatus comprising:
a motion sensor positioned within said pillow, said motion sensor generating an electronic motion signal from sensed motion on said pillow;
a sound sensor positioned within said pillow, said sound sensor generating an electronic sound signal from respiration sounds of a user of said pillow;
a controller having a computing component and electronic memory;
said controller connected to receive said electronic sound signal and said electronic motion signal;
software running in said electronic memory of said computing component, said software configured in a first calculation, ascertaining a motion value based on said motion signal received during a duration of time, and a respiration value based on said electronic sound signal received concurrently during said duration of time; and
said software in a second calculation, determining a sleep level value of said user, correlating to REM sleep, using a combination of said motion value and said respiration value, whereby during an entire sleep cycle of said user, said sleep level value is employable to determine periods of REM sleep and periods of non-REM sleep.
2 . The pillow apparatus of claim 1 , additionally comprising:
said software in a third calculation, estimating a start time and duration of a subsequent period of REM sleep of said user subsequent to an end of said duration of time, based on said sleep level value of said user and an elapsed time since an end of a previously determined period of REM sleep of said user.
3 . The pillow apparatus of claim 2 , additionally comprising:
said controller is in operative communication with an alarm, said alarm having a timed activation to wake said user, at a user determined time;
said alarm configured for an override of said timed activation by an activation signal communicated from said controller; and
said controller configured to communicate a said activation signal earlier than said user determined time, to activate said alarm to wake said user, if said user determined time falls within said duration of a subsequent period of REM sleep.
4 . The pillow apparatus of claim 1 wherein said sleep level value is determined by the sum of said motion value and said respiration value.
5 . The pillow apparatus of claim 2 wherein said sleep level value is determined by the sum of said motion value and said respiration value.
6 . The pillow apparatus of claim 3 wherein said sleep level value is determined by the sum of said motion value and said respiration value.
7 . The pillow apparatus of claim 1 wherein said first calculation also includes ascertaining a temperature value based on a temperature signal received from a temperature sensor engaged with said pillow during a duration of time and said software in said second calculation, determining a sleep level value of said user, correlating to REM sleep, includes using a combination of said motion value and said respiration value and said temperature value.
8 . The pillow apparatus of claim 3 wherein said first calculation also includes ascertaining a temperature value based on a temperature signal received from a temperature sensor engaged with said pillow during a duration of time and said software in said second calculation, determining a sleep level value of said user, correlating to REM sleep, includes using a combination of said motion value and said respiration value and said temperature value.
9 . The pillow apparatus of claim 8 wherein said sleep level value is determined by a sum of said motion value and said respiration value and said temperature value.
10 . The pillow apparatus of claim 3 wherein said sleep level value in said second calculation is determined by an algorithm using one or a combination of calculations from a group including, a sum the ascertained respiration values and motion values, weighted values of each of said respiration values and said motion values, in determining a final sum or product equaling said sleep level value.
