This is the test bed for the RayVan Articial Cochlea in a single FPGA.

The circuits of the complete Minilab fit on four 4in x 6in hand-wired PCBs;
The final product will be much smaller.

Front panel of the RayVan Minilab prototype.

Also a potential product is the Artifial Cochlea PCB alone, ready to be
embedded in a customer's application. The firmware of the Artificial Cochlea
is contained in the Xilinx Spartan FPGA in the middle of the board.

The Data Acquision System emulates a tape-recorder. It makes it possible to record
EEG, EKG, Sonograms etc. without interruption for one whole minute. These one-minute
recordings can be uploaded and downloaded from a PC. Some pre-processing of the
data is also possible in the time domain. A typical use is for accumulating a
library of heart, brain, muscles, etc. sounds and waveforms so that experimentation
can be done in the lab as if the patients were all present at the same time. The
battery charge lasts for days in normal operation. Battery operation insures that
the instrument is portable and that patient(s) are protected from electrocution.
