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.
Its present name Wern Inter AB was registered 1984.
The company has been engaged in,
Mechanical HVAC Engineering design, Control and Inspections for
- Apartment, Hotel, Shopping, Office and Recreational buildings etc
- Swedish Embassy buildings in Europe, Africa, Asia and North America
Slide rule and calculator design
- Slide rule design awarded with gold medal to the Wern brothers
- Slide rule calculator design and production for various clients
Patents
- Touch control for lighting installations patented in 1972
- Patent licence for picture telephony on an ordinary subscriber line, sold 1976 to Ericsson.
Wern Inter AB HVAC Engineering service was closed down year 2000.
P-Phone Control AB (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.

CRW ANGLE TRISECTION.
Historic.
Angle trisection within geometric construction is known as a 2000 year unsolved problem.
Pierre Wantzel proved 1837 that there is no general mathematical solution to solve the
problem with given rules, i.e. using only a straightedge ruler and and a compass which no be used to create a new tool.
Undersigned can now show that above unsolved problem in more than 2000 years has now
been solved by drawing melthod with given rules and by mathematically equation solved exactly.
