Human life is divided into day periods as a main periods which consist of a day and night phase. Most of humans need to sleep a eight hours in a minimum to have their body and all the body function ready in day phase of a day. The second very important thing (instead of 8 hour sleep) is a phase of sleep in which a human is wake up. Waking up of a human in deep sleep phase lead to a very “unhappy” morning and not so nice spend of day. We are trying to develop algorithms to detect mild sleep stages which are the most suitable to human wake up. Actually we use microphone input to record and process sound near the monitored user. All the knowledge is implemented to mobile phone (windows mobile based device) as an intelligent alarm application. Whole application is designed as multithread Real-Time application based on. NET Compact Framework platform in C# language. Filtration and detection algorithms used special Math library Math. NET to process a recorded sound signal. This paper consists of several chapters which describes design, implementation and testing phases of this mobile application development. Actual testing results shows that our developed application detect correctly more than 70% of mild sleep stages of all tested persons.

Patient monitor modules have various inputs for vital function measurement. We can practice many of these measurements with some students in the laboratory of biomedical engineering. However, invasive blood pressure (IBP) measurement demonstration is impossible. This paper is dealing with design and realization of a programmable invasive blood pressure simulator. This device is able to generate programmable behavior of voltage signal with correspond to blood pressure curve. The user communication interface of the device allows choosing the type of generated signal by LCD and 4 push buttons. The wide spectrums of generated signals, which correspond to physiological or pathological blood pressure curves, are stored in a user programmable memory. The output connectors of the device can be directly connected to a patient monitor IBP module input. Invasive blood pressure measurement simulation for educational purposes and calibrating the patients monitors are the general usages of the developed device.

In many desktop applications, an audio signal is captured from the microphone. Unfortunately, most applications lack quality visual indication of arousal microphone volume, which would clearly provide to users (surveillance) information on current values and, if so achieved within a short past. The usability of applications could be in using it as an acoustic monitoring or as a visual area, or volume level for the detection of a communication program. Usability is, of course, also in programs for recording and monitoring audio. The component is designed in .NET Framework.

This project consists in developing applications for mobile phones that allows users to query using the touch screen to check the status of remote devices. Current status of the remote visualization device is arranged on the display, thereby increasing user comfort when operating the remote device (currently designed for GSM communicator GD-06 Allegro), instead of the traditional communication via SMS. Applications for mobile devices is designed for. NET Compact Framework and is designed for Windows Mobile. This application is created in Visual Studio 2008 from Microsoft.

The project is to create an application that converts the audio signal from your computer microphone to record format MP3. Application is designed to record and preserve the audio recordings to a file in a format of lossy compression of audio file compression based on MPEG algorithm (Motion Picture Experts Group). While maintaining a relatively high quality it can reduce the size of audio files in CD quality at about one tenth, for speech, however, it gives much worse results. The advantage of this application is the ability to set frequency range (the sampling) and set the width of the stream, which indicates the number of bits, by which a second of record is registred with. The application is written in C # using Microsoft Visual Studio 2008.

This project is carring out of design and development of software which is able to determine the ideal method of passing cars sweep so that the car is capable of a corner as quickly as possible without compromising safety to crew, or there is a deterioration in passenger comfort, or damage to tangible property transported. Thus a virtual model of a situation such as a desktop application programming in Microsoft Visual Studio 2008 was created. Thanks to the user who made aplication used as an example of automated driving. At the same time it can become the basis for further work on this topic.

This paper deals with the battery life of mobile devices and PDAs at various load levels of the battery. For such testing of PDA battery life, there are many programs in ensuring the current battery status. Our developed appplications can determine the battery at defined time intervals and display its status on the device display in numeric format XX%, where the measured value is stored in an external file in XLS format. Addressing problem is designed to store the measured data of the appplication in tabular form, for better evaluation performance and the subsequent effect on the battery. Testing is focused on the impact of various device appplications, that means from low-end appplications to very demanding appplications with Wi-Fi, Bluetooth, GPS, for the battery status.

The aim of this work is to create application for mobile devices such as PDAs running under Windows Mobile. With this application, and PDA it will be able to process the analog data measured by the A / D converter and display it in graphs. Use of the converter has four analog inputs. These are converted into digital form and transmitted via the communication interface Ethernet to WiFi router. Application running on a PDA uses WiFi connection to download measured data and to processes them. The advantage of this solution is particularly small size and mobility of the PDA. This eliminates the need to transfer the measuring device. This makes a possibility of usage wide especially in the manufacturing industry in the halls where it should be measured in several places at the same time, and the values compared between each other.
