Anemometers", Proc. IEEE Micro Electro Mechanical Systems, (IEEE, 1997)
204-208.


Latest results of a complete microsystem including A/D conversion will be
published at IEDM

36.2 Single-Chip CMOS Anemometer,    F. Mayer, A. Hab=EBrli, H. Jacobs, G.
Ofner, O. Paul and H. Baltes, ETH Hoenggerberg, Zurich,
Switzerland


Products based one these technologies are being commercialized by a ETH
spin-off company. Quantities you requested are no problem to be delivered.
