Motor control in air conditioners with dual sensor less FOC and active PFC Improved energy efficiency and reduced system costs are the driving factors in modern motor control designs. Sophisticated motor control concepts with sensor less Field Oriented Control (FOC) and Power Factor Correction (PFC) help to fulfill these demands. The article shows how these concepts can be used in an air conditioner design for vehicles.

Innovation vs. gloom At the Frankfurt IAA it become apparent that the challenges are yet to be faced for large parts of the automotive industry. But at the same time, the way out of the situation is emerging.
Asymmetric encryption improves car key security Radio-controlled entry systems are ubiquitous in today's cars, but security remains an issue. Fraunhofer Scientists now for the first time have implemented an asymmetric encryption scheme in a car key. They claim that the hardware required is comparable in price and power requirements to conventional symmetric encryption keys.
