If it’s a geek badge of honor to find an entirely new use for something, then the grad students at UC Irvine have earned theirs. Over at the university, a group of grad students have hacked an off-the-shelf digital light projector to create a spatial frequency domain imaging system. Once complete, the budding mad scientists were able to image their thesis adviser’s bicycling injuries and have used it to measure the oxygenation of skin flaps during reconstructive breast surgery. Click past the break for a video of the device in action, and remember this: helping your professor with their sports injuries and reconstructed bosoms may not equal Dean’s List, but it sure can’t hurt.

Bose is best known brands that people associate with high-end audio , That’s because not only Bose quality sound equipment was not up to audiophile standards, but one can buy something that does not meet the strict requirements for the same price, Bose products are always marketed to men – people who want to buy the speakers booming.

One of the first things I noticed about the Companion 5 system sounds strange music. Curved contour of the satellite speakers aim the sound waves in various directions. The sound is then bounced off the wall and different surfaces. Although the results will never deceive you into thinking that a gun shot in the back of the head, this system seems to widen the stereo image for both movies and music, especially by making the speakers sound farther apart than the actual position. Because the stereo separation , as drastic and equal distances, often fun.

The “remote” control is not wireless, but the controller is connected to a speaker cable with a short cable, which plumb crazy. Control module has a mute button, volume control wheel, and two jack (headphones and Aux in). Indeed, the mute is a flat, touch-sensitive surface, and the wheel works like a charm, but I’m sure most users will prefer the portability of a wireless remote.

Type of units used by a variety of industries including desktops, home theater, multimedia, overhead and slide projectors. They are used in the classroom, business, churches, auditoriums, for entertainment purposes, and in the museum. A cheap digital projector to work for many types of industry, educators, and individuals.

Weighing the lighter and smaller dimensions. This makes it easier to travel with them. Some very portable and only weighs a few pounds. Liquid crystal display a digital projector will come in transportable models and will easily fit in a modest backpack thus you can easily hold all of them through motel to motel.

I stood on a crowded CES floor with an assignment I dreaded. I had to look at every 3DTV I could find, an attraction that seemed to be drawing the slowest, most annoying attendees of all of CES into long lines to split a few pairs of glasses.

And these stupid screens are so unimpressive at first glance. To the naked eye, the screen is a tad blurry and maybe even a bit washed out. Then you slip on a pair of lightweight, heavily-douchey, thick-framed glasses. After a moment or two, the world around you goes darker, that once-blurry image sharpens instantly, and suddenly you’re watching 3D.

The image you see will vary with content. You’ll note a light flickering over your eyes, somewhere between the gaping black holes of an old time projector playing silent films and smooth 24 or 30fps video of a DVD or digital projector. But the biggest change is that your TV is no longer a flat pane but a window, an image in which there’s an actual depth your eye can dig through, a digital diorama, if you will.

And if you happen to be looking around a room filled with 3DTVs, or maybe a display of 15 stacked 3DTVs, all of these TVs will have turned 3D. In mass, the effect is a giggle-filled novelty ever so reminiscent of Jaws 3D.

Animation is, by far, the most impressive demo you will see. Impossibly crisp and colorful, the effect is extremely lifelike…for a cartoon. More simply put, there’s a perfect front to back gradient. Every object looks, well, like an object, like something round that takes up real physical space. When, during a clip of A Christmas Carol, Scrooge’s oily, porous nose protrudes from the screen ever so forcefully, you can’t possibly imagine the moment done justice in 2D. The sense of flesh far outweighs what you see in the illustrative lead shot, because truthfully, these scenes have been designed and rendered with information that our displays have been incapable of showing us. With 3D animation, 3D is no gimmick—it’s 2D that’s the lousy undersell. And your eyes will be able to tell as they savor looking as deep as they can into the frame.

Sports are a vastly different, inferior experience. Basketball, for instance, is interesting in 3D but also indicative of the format’s limitations. For one, the court has depth, but the players are quite flat, like a few paper cutouts are dribbling a ball back and forth instead of fully corporeal, 6’6″ titans. Your mind can’t quite reconcile the image, as it’s somewhere between 2D and 3D, meaning it looks more fake, in a sense, than the simple 2D presentation we’ve always seen (the term “uncanny valley,” though not quite suitable in this context, certainly comes to mind). I assume such is a result from the use of telephoto lenses, which are notorious for flattening even 2D images. The effect is even more pronounced in 3D, meaning that stereoscopic 3D shouldn’t (and can’t) be the end game for sports no matter what ESPN tells you. I could easily imagine a multicam arena setup which these blank (flattening) information spots could be filled, and an actual 3D image (a la Pixar) could be piped to consumers, rendered in real time. The effect in sports could truly be something we’ve never seen before (Madden 2010 crossed with real textures, essentially). As of now, it feels more like we’re playing with paper dolls.

Live action film, specifically Avatar, is something I haven’t seen on a 3DTV beyond a few 3D previews. The fast paced trailers—as opposed to the long, expansive shots of Pixar-style animation—don’t lend themselves as well to the illusion (the 3D planes constantly break), and it’s quite difficult to really assess or describe an effect that your eyes can’t chew on for a while. On an IMAX 3D screen, I’ve mentioned that Avatar showed me textures I’d never seen before. On a plasma, Avatar looks far more like a cartoon, and its depth gradient is somewhere between the 2Dish sports and the all-out 3D animations (probably because Avatar itself is much a combination of the two). In the theater, I opened my eyes as wide as possible to take in the bioluminesence of Pandora. On the small screen, a light flicker distances you, almost unconsciously, from the content. But then again, Avatar never looked nearly as impressive in trailers as it did in final cut form, and 3D missiles firing straight at you will always be awesome.

But when things go really bad…

…watching 3D is nothing but pain. Before checking out an LCD or OLED, you put on the shutter glasses, as if all is well and good, and the lights again dim instantly. Each actual frame of the video are just as colorful, sharp and Y-axis-deep as those you’ve seen on better displays. But the frame rate seems to drop, with your favorite Pixar hero moving without smoothness or extreme subtlety. And of course there’s a flicker on top of the odd frame rate, causing the already subpar image to strobe. The overall effect is akin to playing Crysis on an underpowered GPU along with some monitor that goes dark several times a second. It’s sour stacked on sour, an experience with so little redeeming quality you should cease to even consider it.

That annoying CES line I described at the start of this piece? It was at the LG booth, right before I took a look at their 3D plasma prototype, which is slated to be released later this year for $200 over a 2D model. And right when I was ready to give up on glasses, gimmicks and eyestrain, the experience wiped my memory of it all as I stood there transfixed for at least 5 minutes, disregarding the line behind me and watching the same remarkable animated clips over and over. I thought of a new era of filmmakers speaking in an updated cinematic dialect, and I knew that words couldn’t quite describe the sensations—we simply hadn’t decoded them yet.

(Oh, and if you think all of this is too lovey on 3D, read all of my technological caveats here.)

The 120W（2W×40＋20W×2) projector sports five HDMI interfaces, an iPod port and an additional sub woofer connection.

It will be out at the end of this month in Japan (price: $2,280). The projector has both Japanese and English menus so we can expect it to hit international markets soon, too.

While it might be the world’s first digital camera with a built-in projector, it turns out the Nikon S1000pj was actually trumped way back in 1957 when it comes to the convergence of cameras and projectors. The Wittnauer Cine-Twin was an 8mm film camera that could be converted into a projector with the addition of a special base and a few other add-ons like film reels and what-not. Unfortunately there were many factors that prevented the Cine-Twin from catching on back in the day including its 3 heavy D-cell batteries, the fact that the delicate and expensive projector bulb was always in the camera, even when you were out shooting, and it was only sold in jewelry stores (Wittnauer was apparently a famous jeweler.) So here’s to hoping that Nikon has a bit more success with their design.

While 12 lumens means you’re going to have to choose your lighting or location carefully, the tiny size (deck of cards-ish) and improved battery life mean that’s less of a hassle than with any other kind of semi-portable projector. We’ll see about getting one to review; at $350 it may be a worthy investment for people who don’t want their friends crowding around a laptop for a slideshow or YouTube video. It’ll be out on September 1st.

COMING SOON TO A POCKET NEAR YOU: THE MPRO120

3M’s New Handheld Projector Set for September Launch

ST. PAUL, MINN. (August 26, 2009) – This fall, Hollywood’s biggest blockbusters are coming to a pocket near you! Less than a year after launching the MPro110 – the handheld digital projector that won the “Grand Award” in the gadget category of the Popular Science 2008 Best of What’s New Awards – 3M announced today the September debut of the MPro120, the newest member of the MPro family. The MPro120 provides improved functionality, increased portability and an expanded feature set.

The MPro120 is the first projector to incorporate 3M’s MM200 projection engine, the next generation of the MPro family. As announced at the 2009 Consumer Electronics Show, the MM200 engine uses an advanced liquid crystal on silicon (LCOS) electronic imager and boasts enhanced image quality with a full color gamut. The MPro120 provides users with a robust battery life of two to four hours (depending on brightness setting) – enough to watch a full-length film – and, in full brightness mode, achieves a brightness of 12 lumens. Featuring an integrated flip stand, tripod, stereo speakers and a variety of input cables, the MPro120 is ready to use “out-of-the-box” with a wide range of today’s most popular video output gadgets. And, as with its predecessor – the MPro110 – the MPro120 will be the ideal projection solution for laptops and netbooks. Available optional accessories include an adapter cable for Apple® products, component video cable and car charger.

“Following the success of the MPro110, the MPro120 will further reinforce 3M’s leadership position in the development and implementation of advanced projection technologies,” said Mark Colin, general manager, 3M Projection Systems Department. “The functionality of the MPro120 represents technical achievements that were manageable only by the long-term commitment to research and development that is 3M’s hallmark.”

The MPro120 will be on-sale September 1 with an estimated price of $349. Optional accessories are sold separately.

The Coolpix S1000pj is the first digital camera with a built-in projector that lets users project photos or movies clips on any flat surface at up to 40 inches in size. A handy projector stand is included, as is a remote control that can be used to operate the projector, release the shutter, and more. This model features an effective resolution of 12.1 megapixels and a 5x Zoom-Nikkor lens with 28mm (equivalent) wide-angle coverage, along with a similar image stabilization system to the Coolpix S640.

Although a release date is still up in the air, the S1000pj is expected to drop sometime in the near future for an RRP of $699 AUD or $587 US. That’s all well and good, but is this even a good idea? It’s kind of a throwback to the days when your grandfather would bust out the projector and show home movies in the attic (while wearing a sweater and clenching a pipe between his teeth no doubt). It seems a little redundant to me when you can easily view the files on tv or computer screen, but then again, I was never one for torturing relatives with pictures from my vacation.
