Use of Mobile Phones as Intelligent Sensors for Sound Input Analysis and Sleep State Detection

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

Stress Testing of Web Services Interface

Abstract. The aim of this paper is a stress testing of the developed UAS for home care agencies. The developed testing application is possible to use on any others UAS with web service interface. The whole system, including applications developed for the stress testing is based on Microsoft technology .NET. By the help of our test application, the hardware solution for the server was selected on the base of selected home care agency needs

User Adaptivity of Biotelemetric System for ECG Measurement and Visualization

International audienceUsers want a simple, intuitive and graphically attractive interface. On the other hand, it is necessary to change dynamically the user's experience as they use what best viewing area of the device. The biomedical data are not all the latest knowledge in the area. Our work focuses on exploring the possibilities and the revelation of any deficiencies in the currently used procedures and technologies. The main area of interest of our biotelemetric system is to provide solution which can be used in different areas of health care and which will be available through PDAs, web browsers or desktop clients. In paper we deals with a problem of visualization of measured ECG signal on mobile devices in Real Time as well as with a solution how to solve a problem of unsuccessful data processing on desktop or server
