The Gentle Art of Room Correction
Author: Richard Elen.
Abstract: The advent of high-powered DSP (digital signal processing)
systems has led manufacturers to attempt to equalize their systems
to compensate for problems with the listening room acoustics.
However, simply throwing DSP power at the problem is not necessarily
the most effective approach. Richard Elen looks at how Meridian
Audio has addressed the problem with its Room Correction system,
included in the latest version of its high-end digital home theater
processor.

Emerging Digital Micromirror Device (DMD)
Applications
Author(s): Dana Dudley / Walter Duncan / John Slaughter
Abstract: For the past six years, Digital Light ProcessingTM
technology from Texas Instruments has made significant inroads
in the projection display market. With products enabling the world's
smallest data and video projectors, HDTVs, and digital cinema,
DLPTM technology is extremely powerful and flexible. At the heart
of these display solutions is Texas Instruments Digital Micromirror
Device (DMD), a semiconductor-based "light switch" array
of thousands of individually addressable, tiltable, mirror-pixels.
With success of the DMD as a spatial light modulator for projector
applications, dozens of new applications are now being enabled
by general-use DMD products that are recently available to developers.
The same light switching speed and "on-off" (contrast)
ratio that have resulted in superior projector performance, along
with the capability of operation outside the visible spectrum,
make the DMD very attractive for many applications, including
volumetric display, holographic data storage, lithography, scientific
instrumentation, and medical imaging. This paper presents an overview
of past and future DMD performance in the context of new DMD applications,
cites several examples of emerging products, and describes the
DMD components and tools now available to developers.
