(1) Highest quality biosignal data base on www.biosignal.at
Register yourself and download highest quality biosignal data for verifying and testing your algorithms. The aim of the data base is to provide well documented data sets along with results published in peer reviewed journals to the scientific community. Users are very welcome to provide their own published data to the community.
see: http://www.biosignal.at

(2) g.MOBIlab - High-speed mobile biosignal amplifier under MATLAB and Simulink
The MATLAB/Simulink integration for g.MOBIlab enables now an integrated development environment for mobile biosignal acquisition systems. A TCPIP network connection enables remote control and online data transfer. So acquisition of biosignals and other signals under difficult conditions e.g. in a vacuum chamber or cold-chamber can be performed.

(3) g.tec's Data Acquisition, Real-Time, Signal Analysis and Stimulation Tools are now available for MATLAB 7 and SIMULINK 6
Benefit from the new features under MATLAB 7 and the total biosignal development environment from g.tec. Laboratory PC/notebook based biosignal research systems as well as mobile Pocket PC based system can for the first time beeing developed under a single environment.
For an overview see http://www.gtec.at/products/developerzone.htm

4) The Fifth Edition of the EEG primer "Electroencephalography, Basic Principles, Clinical Applications, and Related Fields" by E. Niedermayer and F. Lopes da Silva including 2 Chapter contributions from g.tec medical engineering is now available.
Drs. Niedermeyer's and Lopes da Silva's text is now in its thoroughly updated Fifth Edition available. An international group of experts provides comprehensive coverage of the neurophysiologic and technical aspects of EEG, evoked potentials, and magnetoencephalography, as well as the clinical applications of these studies in neonates, infants, children, adults, and older adults.This edition includes digital EEG and advances in areas such as neurocognition

(5) New Release of g.ECGtoolbox for g.BSanalyze is now available
The g.ECGtoolbox comprises new outstanding facilities to investigate also beat-to-beat signal changes in ECG including. A versatile beat editor allows extracting characteristic points in the ECG and classification of ECG beats into different classes of pathology.

(6) g.PAH system, Programmable Attenuator and Headbuffer for Auditory Steady-State Responses (ASSR)
The device is used to accurately attenuate a sound signal in steps of 1 dB. If the input signal is e.g. attenuated by 20 dB then the output signal amplitude is 1/10th of the input signal amplitude. Such an accurate control of damping is necessary in the field of e.g. objective audiometry. Depending on the stimulation signal ASSR at different frequencies can be identified in the frequency domain. Typically Multiple Auditory Steady-State Responses (MASTER) are evoked using 4 different carrier and 4 different modulating frequencies.
