Industrial internet increases requirements for antennas

Wireless devices are becoming more common due to industrial internet. This means an increasing number of devices with an antenna. The antennas are usually covered and hidden inside the devices. Industrial internet devices are also heading for a direction where they become smaller, cheaper and less power consuming all the time. Often they are also battery-operated. All this causes headache for a person responsible for wireless (radio) link performance and operation.

Toroidion super car: a challenge for power electronics

Toroidion electric car’s release in Monaco 2015 attracted huge international attention. Its promised power of 1 megawatt, or over 1 300 hp, ferocious acceleration and operational range of 500 km left the experts' jaws open. The father of the car idea, Pasi Pennanen, has made a long career in design tasks with cars like the Formulas, Jaguar, Aston Martin and Honda. Pennanen needed experienced experts for every component to design the technology of the car.

Embedded AC drive

Alternating current (AC) motors have over a century of history. During the last decades, they have dominated the market for motor drives used in industrial and consumer applications. But in the case of variable speed drives, there were some areas where DC motors were the only option for quite long, especially when torque control or a high dynamic control was required. This is now changing as the availability of compact and effective hardware solutions lets vector control expand to cost-sensitive areas like home appliances and consumer electronics.
