Matchbox Sized Color Projectors?
Justin Nolan sent in a very brief link about
ultra small projectors which says
"Upstream Engineering is willing to provide miniature color video projectors for use with portable video player, travel TV, laptops and handhelds next year. Upstream's patented technology, called Photon Vacuum, maximizes the amount of photons sent to the target from the light source in a minimum space and allows the creation of devices free of a variety of components currently used in projectors that unnecessarily waste energy. Photon Vacuum enables the smallest projector designs in the world, ultimately to a size of matchbox. The company says is going to push the power consumption of the whole device ultimately to below 4 watts while still gaining a travel-TV sized color projection" You can also read Upstream's website for almost as little information.
Are they going to be 2k US+ like conventional projectors? Will they force the price of conventional projectors down?
PDA Live picked a hell of a time to upgrade their software. >:(
Does this mean that projectors will get smaller, cheaper and more high quality?
The holy grail!
Chris
Site says it's down for "software upgrade".
Anyone got a mirror?
They made the projectors to fit inside of a Matchbox car!!!
The site is down for "Software Upgrading" :(
Now, if lots of these min-projectors could be put together in a matrix, will this mean that, finally, big screen TVs can be produced more cheaply. (If one mini-projector does dead, just swap it out).
How do I know? The Finns are trustworthy and don't lie. Can't say the same about the Danes or Swedes. The Swiss are trustworthy too.

Thats the spirit. Every electric and electronic appliance should go for that goal. While the effort to finally get a cheap, clean and reliable source of energy is good, we must for once pay attention to nature and reduce power consuption to a minimum, that would buy us some time or being able to rely in smaller sources of energy like wind or solar pannels. Size does matter!!,
Although I dont know what im going to do whith such a tiny proyector, maybe i'll put it in my back pockent and sit on it afterwards and break it. Or have it stuck in a child's ear.

Upstream's unique and revolutionary technology, called Photon Vacuum, practically maximizes the amount of photons sent to the target from the light source in a minimum space. This is not an easy trick since the etendue law of light in physics requires more space for better efficiency. Our special technology enables us to get rid of a variety of components currently used in projectors that unnecessarily waste energy. The current table projectors extract typically only a few watts of light power out of 200W of input power.

It is possible to push the power consumption of the whole device ultimately to below 4 watts while still gaining a travel-TV sized color projection. There are a myriad of possible applications for this technology.
Obviously this would hinge on cost, but I seems to me that this would make it much more practical to integrate projected images through a living or work space. A lot of futuristic concepts include projectors in their design, but these units are always large and ugly. Having projectors conveniently displaying information and entertainment (TV, artwork, notifications, etc.) on surfaces throughout the house would be "really neat"

I am sure something useful will come, eventually, but don't hold your breath waiting for anything cool to buy any time soon.
This issue is a bit more complicated than you think.
Since quitting the Navy six months early at age 27 so he could run for Congress on an antiwar platform, John Kerry has built a political career on his service in Vietnam. His unsuccessful 1970 congressional bid lasted only a month, during which it proved impossible for even he to get to the left of the winner, Robert Drinan, but it forged a conflicting political persona - one hammered out between his combat medals earned in the Mekong delta and the common cause he made with the enemy upon his return home.
Now, at age 60, the junior Democratic senator from Massachusetts is milking his veteran status once again in an effort to show that he's tougher and more patriotic than the man he seeks to replace, President George W. Bush. And, as unrepentant as ever for his pro-Hanoi activism, he is just as conflicted in 2004 as he was in the 1960s.
If there is any consistency in Kerry's political career, it is his in-your-face use of that four-month stint in Vietnam. He enlisted like many other young men of privilege, trying to serve without going to the front lines. When in 1966 it looked like his draft number was coming up during his senior year at Yale University, and already having spoken out in public against the war, Kerry signed up with the Navy under the conscious inspiration of his hero, the late President John F. Kennedy. As a lieutenant junior grade, Kerry skippered a CTF-115 swift boat, a light, aluminum patrol vessel that bore a passing resemblance to PT-109. He thought he'd arranged to avoid combat. "I didn't really want to get involved in the war," he later would tell the Boston Globe. "When I signed up for the swift boats, they had very little to do with the war. They were engaged in coastal patrolling, and that's what I thought I was going to do."
Soon, however, Kerry was reassigned to patrol the Mekong River in South Vietnam, a formative experience for his political odyssey. The official record shows that he rose to the occasion. It was along the Mekong where he first killed a man, aggressively fighting the enemy Viet Cong and reportedly saving the lives of his own men, earning a Bronze Star, a Silver Star for valor, and three Purple Hearts in the process.
Kerry opted for reassignment to New York City, where - as a uniformed, active-duty officer - he reportedly began acting out the antiwar feelings he had expressed before enlisting. Press reports from the time say that he marched in the October 1969 Moratorium protests - a mass demonstration by a quarter-million people that had been orchestrated the previous summer by North Vietnamese officials and American antiwar leaders in Cuba (see sidebar, p. 27). Kerry had found his purpose in life. The New York Times reported on April 23, 1971, that at about the time of the Moratorium march, Lt. Kerry had "asked for, and was given, an early release from the Navy so he could run for Congress on an antiwar platform from his home district in Waltham, Mass."
For Kerry, politicizing the nation's war effort for partisan purposes was the right thing to do, in contrast to the violent revolutionary designs of colleagues who were out to destroy the system. Kerry didn't want to take down the establishment. He wanted to take it over. His aborted, monthlong 1970 congressional campaign was a victory for him politically, as it landed him on television's popular Dick Cavett Show, where he came to the attention of some of the central organizers of the antiwar/pro-Hanoi group known as Vietnam Veterans Against the War (VVAW).
VVAW was a numerically small part of the protest movement, but it was extremely influential through skillful political theater, the novelty of uniformed combat veterans joining the Vietniks, and a ruthless coalition-building strategy that forged partnerships with the Communist Party USA (CPUSA), its Trotskyite rival, the Socialist Workers Party, and a broad front that ranged from pacifists to supporters of the Black Panthers and other domestic terrorist groups.
Kerry signed on as a full-time organizer and member of th
There's nothing on that site to indicate that they're anything other than vapourware.
It doesn't follow that it's impossible - on the contrary, I think this is a technology we'll be seeing very soon - I just doubt that it will be from this company.
So why do I think we'll be seeing it soon ? Simple, grasshopper. Lasers. It's easy enough to build a poor quality monochrome vector display out of a laser diode and a couple of mirrors on motors. That's expensive and clunky.
A laser diode and a couple of piezo-transducer-mounted mirrors would be a slightly more elegant mechanism, and if you can build a vector display with this, you ought just as easily to be able to build a raster display.
So all we're missing is the cheap green laser diode and the cheap blue laser diode to complement the existing cheap red laser diode.
Now, you CAN buy a green laser pointer that's only moderately painfully expensive - and now that there's an imminent demand for blue laser diodes for high density DVD players I'm hoping their cost will plummet.
I don't have the skills to build this, but I'm hoping someone will get onto it soon.

First in the world, Upstream Engineering introduces a revolutionary optical technology that will enable video projection from matchbox-sized device running on batteries.
Our expertise covers all the necessary areas from micro-optics to low-power digital electronics. We design custom projectors based on our unique technology.
But perhaps you are a Democrat and you disagree with Bush. Well then, vote for Nader. Think about the differences between Kerry and Bush. Can you, as a Democrat, see many? Kerry is in bed with big business and any true Democrat could not vote for him in good faith. So toss a vote Ralph Nader's way - who knows, he could shock the world. :P
For people who are often going to meetings, this makes it pretty quick to set up, could go off your laptops power source so no need looking for an outlet, no need to adjust it, nice and fast. If it is priced correctly, I would even buy it just to have since, you never know when a gadget like this will come in handy. Ok okay, yes I was the one to buy the USB laptop lamp, and no I don't use it :(

Their website doesn't even feature a single photo, prototype, or past products. I'm surprised this article was even approved. It certainly looks like yet another one of those companies which try to persuade people to buy shares, counting on a 'revolutionary' product which the company is unlikely to ever succeed in producing.
Their website is online now - still not very much information.
Are they sure they didn't mean photon vapor? I hear they are working on fusion as well...

First of all, I'm guessing PDALive is running a matchbook size webserver and it started to flame so they took it down.
This product (if it's not vapor) looks like it could be a great advance in this technology. I use a "regular" size projector daily and it's a pain in the butt to move the whole setup when we go on the road.
The other issue is price; a decent LCD project costs $2K. If they could get the price down to under $500, that would be big. As it is, we have to move projectors quite often due to the cost of buying new ones.

A brief google of "photon vacuum" comes up with a series of papers in the realm of quantum physics http://www.iop.org/EJ/abstract/0954-3899/29/1/311.
I need to finish reading what papers I can find regarding this concept, but so far it looks like something still in the arena of pure science. One article also refers to carbon nano tubes, so if this isn't vapor ware it will be expensive.
But I have seen it - at least the prototype in a Finnish magazine (Just can't remember which one..)
It had a very small controlling electronics part and the actual projector part was itself very small compared to a matchbox next to it. In that picture it had no casing at all.
For that size, they were able to project up to 1024x768 resolution. For larger sizes, projector had to be bigger.
I try to find some network references if there are any..

Hey, I have one of those too! And no, it isn't practical for anything. I do keep it in my pack, though, and whip it out as a coolness factor at LAN parties. The newbies are scared shitless of me for the fifteen minutes of a WC3 game. I also have a Microsoft Strategic Commander that serves the same function; I plug it up too if I want 'em to be scared for a good half hour. The truth, of course, is that I suck at WC3, but I'm pretty good at the mind game.
was about discovery and making great things. But apparently it's about patenting the best ideas.
Why can't science be for the good of all not just for the ruling class? I hate it when people come up with good ideas then think they have to patent them.
What would we be allowed to know about physics if Einstein patented his ideas? We'd have to pay to use E=mc^2.
Science is about profit not discovering great things and sharing them with the world.
The definition of vaporware is not that things indicate that they could not exist but that there is not evidence that it does exist. I only visited a few pages because it was under a slashdotting, but I did not see anything suggest the means to this mechanism. So, does it mean it is impossible? Certainly not, just as it is possible for Ashcroft to spontaneously start break dancing; however, they have to "prove" they are not vaporware.

Do you actually believe that you can project a reasonable image with _4 watts_ of power? You need energy to create photons. Even with zero heat loss, you can't get a luminous image out of 4 watts. This is vaporware at best.
Lets face it, Michael Moore is an idiot and we should take back his Oscar. Where does he get off calling our President fictitious...moreover, sending a quarter of a million troops into war for "fictitious reasons."

They talk about a "photon vacuum" but all is see is an information vacuum and a product vacuum. There is no there there.
Religion is the main cause of atheism.
"The size of the projection will be initially around the size of standard travel televisions."
Does anyone have a figure for the amount of light needed per square foot for good visibility on a screen with normal meeting room lighting? Assume solid state light source efficiency levels.
There are two interesting parts to their claims. One is reduction in size, the other is reduction in power requirements. The statement above from their website leads me to believe they're really just reducing the size of the device - the 4W figure is spread over just a few square inches. When they need to cover several square feet the power consumption will increase proportionally, and so will the size of the device to allow for adequate cooling.

Admit it, you thought about skipping down Troll Lane, but lost your nerve
Whether this company is BSing or not, were still getting to the point where technology is getting smaller and smaller, Look how far computers have come along, even compared to 10 years ago, most of the stuff we have was just someones pipe dream, and compared to 30years ago, most of it was science fiction at best. The only things holding us back realisticly is major coprerations censoring the information that is available to the masses, technological advances that would revolutionalise industries and hence make them loose profits. Where would we be today if during the industrial revolution the protestors had won? We would still be in the dark ages, no electricity, no machines, no technology.
If at first you DON'T succeed, Skydiving is NOT for YOU!!
Don't forget that while the projector won't be 100% efficient, neither is a light bulb.
It is possible to push the power consumption of the whole device ultimately to below 4 watts while still gaining a travel-TV sized color projection.
Well, a 15-inch LCD panel consumes about 30W, all in. I don't know how big a travel-TV is, but less say it's 7.5inches. Assuming power is proportional to area, then an LCD 7.5-inch travel TV would consume 7.5W. I assume some of that power is absorbed in the colour filters, and some more is lost in the polarizer, and some is used by the TFT itself. So it doesn't seem impossible to me to have a 7.5inch display that consumes 4W.
Of course this could still be vaporware, but I don't think the 4W number is a dead giveaway.
Is it just me, or does this remind anyone of the advertising from Minority Report? You know - "Welcome back to the Gap, Mr. blah!"

Yeah, most companies would keep this kind of tech to themselves, to impress their friends!

This is not an easy trick since the etendue law of light in physics requires more space for better efficiency. Our special technology enables us to get rid of a variety of components currently used in projectors that unnecessarily waste energy.
I hope they are able to do what they claim, but I'm always wary of companies that claim to have overcome the laws of physics.
Maybe I'm just bitter after getting burned on that anti-gravity skateboard deal.
What were you expecting?
Try an uncooled 4-watt bulb squeezed into half a cubic inch of space on your lap. Goodbye, sperm!
So... you couldn't use a regular projector?
Traditional PDAs are about to make a real change, with both Input *AND* output projected.
You'll place your PDA on a table and project the screen against a wall, or stretched vertically, onto the table ahead of it, while it simultaneously projects the keyboard onto the table.
I also anticipate the keyboard projector will ultimately detect finger movements in a separate area, and act as a mouse also.

Merge this technology with some other bleeding edge 3d/holographic technologies and some concepts that used to only exist in scifi suddenly have some real-world possibility.
Palmtop holographic photos and/or projections could seem likely in the next few years?
if these sell for computers, and at a good retail price, viewsonic's in deep shit, most of their projectors are fscking between $1500 and $3000
this would be great to see in use for computers, then people with laptops need to show a quick presentation, they can plug one in quick and show it oog, or laptops with these built in.
wouldnt be too shabby.
They could be doing laser scanning, but I doubt it. I bet they're using LEDs as the light source. Possibly micro arrays for the actual image, but most likely still sticking with a small LED array that has the three colors, a special lensing system that focuses them through a monochrome LCD (cheap non-high temperature transmissive) and then another lens which then produces the output.
This would provide several advantages. First, it would be fairly efficient since 4W of LED power is still fairly efficient (though still 'hot' and not close at all to the ideal 100%). The cheap LCD display due to the lower heat. Small size, especially if high index refrective lenses are used.
Disadvantages are many. Traditional projectors use a bulb which, for all intents and purposes can be modelled as a point light source. Optics are easy, comparatively. For a LED array the optics would be...non trivial. I suppose they could be using single LEDs but even then the leds are seperated, which still makes the job difficult. Another is that the smaller the package, the smaller the optics. The smaller the optics the worse the image. There's a reason you'll never get 4 meter telescope pictures out of a 10cm telescope. The resolving power of the lenses is limited by their size. The LED element will be huge compared to the lens size, and the picture is simply going to be poor.
It'll happen, through this speculative idea or through another, but real multimedia projectors for a given size projection have to be at least as large as the lens has to be for the quality you want. The only thing they might be able to make gains on without ruining the quality are lamp efficiency, lower heat output (these are coupled), and the design of the lens systems currently needed to throw a decent image across a room.

That's basically what the pen computer mentioned a week or so ago was on about - another example of a device looking at integrating a small-scale projector (Picture of pen computer in use). The keyboard was from canesta and the display was an LED projector. The article was a bit hazy on whether their display model contained a working version or not, but as the prototype did cost around $30,000, it might be a few weeks before it gets particularly cheap.
with something that small the cable is going to outweigh the projector. you'd better be very careful how you set it up or your $5K projector could just go whizzing off the table if you've got some cable overhang.
or maybe there's going to be a nice big rubber sucker on the bottom?
In the Boorman film ZARDOZ (1974), the futuristic denizens of that film use mini-projectors like these in their rings for interfaces. You can also see Charlotte Rampling and Sean connery in various states of undress.
-- Real Stupidity is the Artificial Intelligence of the 21st century
Here's a possible solution. Use a an ultra-small LCD such as the kopin cyberdisplay (www.kopin.com), which is a transmissive display, and combine it with some optics and a luxeon 5watt LED. Voila, you have a VERY small projector, which is battery operable and cheap. I looked into it, and have discovered that it is feasible, if only I could find a cheaper source of microdisplays! Kopin caters to OEMS, and all other manufacturers of similar LCD's do as well. Samples and development boards are rediculously expensive. Any advice?
It is definitely not a new idea...

Siemens already have this technology, working as a prototype... from 2001!? Upstream is a laggard!
/ ar tikel03/
http://w4.siemens.de/FuI/en/archiv/pof/heft1_02
The miniature format is also of great interest in the field of projection technology. Siemens has developed a matchbox-sized daylight projector that can be plugged into a cell phone with a corresponding interface. The projector can be used for presentations in small meetings or for surfing the Internet. This projection cell phone was recently presented at the CeBIT 2002 computer show in Hannover, Germany. An LED array in the module lights up a microdisplay through a beam splitter. The light is modulated with the image information by the display, then exits through the projection lenses. Full-color pictures can be generated by rapidly illuminating the monochrome display with the red, blue and green LED colors in sequence. "This mini-projector can project onto any surface--even a piece of paper or the back of an airplane seat," says Marco Werner from Siemens Information and Communication Mobile. The projector currently generates 1.1 lm, enough to illuminate a postcard-sized surface. "But the prototype still offers enormous room for improvement," says Werner enthusiastically. With optimized design and equipped with more intense light-emitting diodes, it should be possible to improve the luminous efficiency by a factor of ten over the next two years.
Of course, lasers have also been considered as a light source. Their use would make it possible to eliminate the focusing optics and to project onto curved surfaces. However, suitable miniature laser diodes are currently available only in red. The efficiency level of the blue and green solid-state lasers now on the market is still too low. In the distant future, Werner can also imagine 3D laser projectors that have no need of fixed projection screens. In such a situation, the image would then be created on a boundary surface like a patch of air whose density has been altered using ultrasound.
Wouldn't that be cool? Just stick it in your PCMCIA slot, then tilt the laptop so it points at the screen.

I know I'm horribly ignorant about all of these things, but why not use HID bulbs for projectors? Everyone is so concerned about light output, heat, bulb life, etc. It seems like HID would be better on all of those counts.
