Mobile Usability: How Nokia Changed the Face of the Mobile P

When it comes to delivering product design innovations to mobile device users, Nokia is the yardstick by which all others are judged. Now the process and working methods that have enabled Nokia to revolutionize usability are fully explained for the first time in this beautiful, four-color book.

Written with insight by two veterans of Nokia's design triumphs (co-author Christian Lindholm was featured in the August 2002 issue of Business 2.0 magazine)this one-of-a-kind reference vividly delivers:

* The complete design process, from concept creation to product testing
* The future of small interfaces
* Usability engineering in practice in the mobile environment
* The elements of a Nokia User Interface
* First person accounts of the product development cycle

The design of Switching Power Supplies has become one of the most crucial aspects of power electronics, particularly in the explosive market for portable devices. Unfortunately, this seemingly simple mechanism is actually one of the most complex and under-estimated processes in Power Electronics. Switching power conversion involves several engineering disciplines: Semiconductor Physics, Thermal Management, Control Loop theory, Magnetics etc, and all these come into play eventually, in ways hard for non-experts to grasp.

This book grows out of decades of the authors experience designing commercial power supplies. Although his formal education was in physics, he learned the hard way what it took to succeed in designing power supplies for companies like Siemens and National Semiconductor. His passion for power supplies and his empathy for the practicing or aspiring power conversion engineer is evident on every page.

* The most comprehensive study available of the theoretical and practical aspects of controlling and measuring Electromagnetic Interference in switching power supplies, including input filter instability considerations.
* Step-by-step and iterative approach for calculating high-frequency losses in forward converter transformers, including Proximity losses based on Dowell's equations.
* Thorough, yet uniquely simple design flow-chart for building DC-DC converters and their magnetic components under typical wide-input supply conditions
* Step-by-step, solved examples for stabilizing control loops of all three major topologies, using either transconductance or conventional operational amplifiers, and either current-mode or voltage-mode control.
* CD-ROM includes Visualizations based on Mathcad and Mathcad calculations, including Mathcad files, Excel spreadsheets, Powerpoint Seminars, and PDFs all for power supply design
