Steady State Visually Evoked Potentials have been known for several decades and they appear in the primary visual cortex of brain as a result of light stimulation of the sense of sight. In this article a simple method for electroencephalographic data acquisition is presented. The system is based on the DSM-51 unit connected to goggles with blinking diodes and Mindset-1000 EEG amplifier with 16 channels. We present self-developed hardware and method of effective synchronization for the light stimulation and brain activity recording.

Despite the quick development of medicine and associated medical technology, there are still many patients with very severe neurological deficits who need far more sophisticated solutions, such as brain computer interfaces (BCIs). Our research aims at becoming familiar with BCI technology and the assessment of the possibilities of selected subjects in the area of P300-based BCI. An indirect aim is a discussion on the procedures of patient preparation for BCI installation, possible threats and limitations. Our research presents one of the possible efforts towards better documentation of investigating neural correlates of brain processing.

This paper focuses on finding the most efficinet way of performing local and remote computations with web appliacation based on ActionScript language. Tests involve comparsion of several scenarions which uses pure ActionScript, ActionScript with Alchemy project and ActionScript connecting with C application over AMF protocol and with FileReference class.

The computer program controlling MALDI system and a time of flight mass spectrometer is described. This program allowsto reduce a number of necessary activities for operation of the spectrometer as well as to raise an operational safety of this equipment. Additionally an advantage of the computer control is possibility of quick and automatic changing of any measurements parameters in order to reach the best mass resolution of the spectrometer.
