This could be used for projecting a virtual keyboard on any surface.

This is like those interactive projections in the malls. A projector (with DLP in it) projects an image on the floor or on the wall and kids can interact with the objects in the image. It is a great idea to apply this technology to touch screen. Good thinking. TI.

Old TVs don't need carrying, they just just go up in smoke :-) Structured light is a good example of lateral-thinking to solving a difficult or insoluble problem (3D image analysis) simply by re-writing the problem (structuring the illumination). Can't do it for all cases, but there are markets for this partial solution.

thank you @ghova, how heavy is your DLP TV? I moved recently and had to pay someone to take my old Sony CRT TV, it was soooo heavy ;-)...Kris

AFAIK Mitsubishi is the only current maker of DLP TVs. Their drawback is that they're up to a foot thick. They have the advantage of having a wider color gamut than LCDs or plasmas. $1600 got me 65" of gorgeous 1080p. Try that with an LCD.

That's great that TI has found a new use for their mirror MEMs. Since TVs have gone to LCD, the only use left for the DLP is projectors and very large screen TVs.

How small are these MEMs structures? Kris

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
