Adaptive dimming and adaptive boosting backlight technologies for LCD-TV systems Design How-To 11/14/2007 Post a comment LCD-TV systems need to render video and multi-media images with an optimal front-of-screen performance. They have to meet many requirements, like: contrast, brightness, color, flicker, motion portrayal, viewing angle, dissipation and cost. All these items are directly related to the backlight. In this paper we will show the benefits of adaptive dimming and adaptive boosting technologies, and extend the scope to 2D backlights
DSP-based PFC chips claim lowest harmonic distortion Product News 11/13/2007 Post a comment Marvell's digitally-based 88EM8011 and 88EM8041 power-factor-correction (PFC) controllers, for universal PFC front-end boost conversion, flyback converters, AC/DC LED drivers, ballasts, and TV/monitors, claim the lowest total harmonic distortion in the industry.
Robust Energy - Meter Network with RS-485 Design How-To 11/9/2007 Post a comment Electronic energy meters steadily are replacing the historical, electromechanical meters in industrial plants and commercial buildings. Robust RS-485 differential signaling has become the preferred method of remote data transmission in these harsh and noisy environments.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
