Besides industry funded research and independent strategic projects in research areas with special scientific challenges and high future application potential the third and most comprehensive way of technology transfer is the founding of spin-off companies; since 2008 three spin-offs were emerging from PES: Celeroton (2008, ultra-high speed drives), Enertronics (2010, high bandwidth wireless measurement technology), and Gecko Simulations (2012, multi-disciplinary modeling and simulation).
