As of 2009, HSR has terminated all activities.
Its life was short but active and the site has many references in the literature and on the internet.
Therefore, the below links will be kept alive for a few years.



The 'MCH Slaapcentrum', a large centre for sleep and wake disorders in The Netherlands.

The European Data Format, a standard format for Sleep and EEG recordings, with the EDF(+) viewer Polyman.

The Siesta Group, a PSG scoring solution for diagnostic sleep centers.

And finally, the silicone-rubber respiration sensor,  the EEG-microcontinuity analyzer, the EDFtoWAV converter, more medical electronics / software developments, and Bobs CV.
