Concentrating the computational power of a multimedia desktop or laptop computer into a central processing unit only slightly larger than a hand-held organizer, wearable PCs are finding plenty of users in the commercial world.

On assembly lines they are welcome in tight and busy quarters where even a laptop computer has no surface on which to perch. Others in industry are being used to help repair factory equipment, inspect airplanes and track repairs, or keep tabs on inspection equipment that must be brought on site and then removed. Physicians are using them to access patients' charts and e-mail messages. And anyone who has tried unfolding a laptop in an airplane's cramped cabin might prefer this small PC, too.

The ability to conveniently charge an EV away from home is a top concern for many EV owners. A 2022 survey of EV owners by Forbes indicates that 62 percent of respondents are so anxious about their EV range that travel plans have been affected. While “range anxiety” may be overblown, the need for an extensive and reliable external charging infrastructure is not.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Rohde & Schwarz

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
