Ulrich was honored at the 2014 IEEE International Frequency Control
Symposium May 19-22 in Taiwan:
<http://www.arrl.org/arrlletter?issue=2014-05-29>
the award recognizes "...leadership in the frequency control
community..." the main award was "for the development of PC software
now allowing nonlinear noise analysis of RF circuit ".
Take also a look to this paper, from spark generators to modern VCOs:
