WERN INTER AB
WERN INTER AB started 1963 in Sweden as the HVAC consulting engineering company,
Wern Inter VVS AB. It was founded by Carl R. Wern, a Registered Professional Mechanical Engineer in the state of Michigan, USA. Carl´s brother George joined in 1964 the company.

P-Phone Control AB
The company (PPC) was founded 1992 by Carl together with his brother George in a joint
venture agreement with their brother Lars who is a registered European Patent Attorney.
The Wern brothers proximity sensor was first used in lighting installations for touch control and
thereafter in art museums as invisible shields preventing exhibited objects from being touched.
Today called PeriProx, the technology has been shown applicable for providing enhanced security
in 2000 to a Saab car and in 2009 to a Scania truck. Its usefulness for precise proximity sensing was shown in 2010 by Ericsson´s Connected Tree at Barcelona, Hannover and LasVegas international fairs followed by a permanent exhibition at Ericsson Studio in Kista and by a PeriProx patent in 2012 on a monitoring system for prevention against natural as well as man-made disasters.
