LCD TVs get dimmer to lower backlight costs

December 3, 2012 1:59 pm | by Jimmy Kim, NPD DisplaySearch | Articles | Comments

Historically, TVs have had brightness higher than 400 nits, as they are often placed in the center of a large, bright, room and viewed from large distances and viewing angles. In some cases, however it is placed in sunlight, close to a window. On the other hand, display brightness of less than 300 nits is typically sufficient for an IT device....

A blow to wind energy

September 4, 2012 10:13 am | by M. Simon | Blogs | Comments

My local paper says that the wind energy business is likely to slow down in 2013. They explain that it will be bad for a local manufacturer that makes parts for the turbines and who also makes machines to make the parts. When you make 10 ton hubs for the turbines it is best to make them as close to the installation site as possible. Otherwise the shipping costs can ruin your profits.

Power considerations in advanced embedded systems

August 8, 2012 11:16 am | by Alix Paultre, Globtek, www.globtek.com | Blogs | Comments

The migration of smart subsystems into products at every level of operation represents a true fusion of the electronic and mechanical, representing the next, and possibly the culmination of, the industrial revolution. However, the integration of sense, motion, and logic into all portions of a system also brings with it new (or old in new clothing) challenges in power management.
