Sleep is not just a passive process, but rather a highly dynamic process that is terminated by waking up. Throughout the night a specific number of sleep stages that are repeatedly changing in various periods of time take place. These specific time intervals and specific sleep stages are very important for the wake up event. It is far more difficult to wake up during the deep NREM (2–4) stage of sleep because the rest of the body is still sleeping. On the other hand if we wake up during the mild (REM, NREM1) sleep stage it is a much more pleasant experience for us and for our bodies. This problem led the authors to undertake this study and develop a Windows Mobile-based device application called wakeNsmile. The wakeNsmile application records and monitors the sleep stages for specific amounts of time before a desired alarm time set by users. It uses a built-in microphone and determines the optimal time to wake the user up. Hence, if the user sets an alarm in wakeNsmile to 7:00 and wakeNsmile detects that a more appropriate time to wake up (REM stage) is at 6:50, the alarm will start at 6:50. The current availability and low price of mobile devices is yet another reason to use and develop such an application that will hopefully help someone to wakeNsmile in the morning. So far, the wakeNsmile application has been tested on four individuals introduced in the final section.

The project deal with system development for data management and scheduling of personal sources in home care agencies. Development is buckthorn from analyses, over proposal, implementation and resulting testing application, thereby try cast over whole problems software engineering. System consists of the three main parts -PC application, mobile application and database server. All these parts are built on technology Microsoft .NET solution namely on performances .NET Framework 3.5 and MS SQL server 2008 express edition for PC application, .NET Compact Framework 3.5 and MS SQL server 3.5 Compact Edition whereon be created database server for mobile application. System works offline, whereas synchronization mobile arrangement with data in database is made only in agency by the help of technology USB, Bluetooth or WiFi. Software layer synchronization administration data is based on technologies ADO .NET and Linq. System will further develop and will base for advancement biomedical science research framework.
