Synopsis: Ict: Data: Digital data:

The researchers reached data transmission rates of 32 gigabits per second across 2. 5 meters of free space in a basement lab at the University of Southern California.

For reference, 32 gigabits per second is fast enough to transmit more than 10 hour -and-a-half-long HD movies in one second and is 30 times faster than LTE wireless. ot only is this a way to transmit multiple spatially collocated radio data streams through a single aperture,

Faster data transmission rates have been led achievedillner himself a team two years ago that twisted light beams to transmit data at a blistering 2. 56 terabits per secondut methods to do so rely on light to carry the data. he advantage

The ability to compress quantum information just as we do with digital data could open up huge potential for more powerful computing.

The color display technology delivers bright red blue and green hues from five-micron-square pixels that each contains several hundred aluminum nanorods.

and the spacing between them researchers Stephan Link and Jana Olson showed they could create pixels that produced dozens of colors including rich tones of red green

and washed outsays Link associate professor of chemistry at Rice and the lead researcher on the PNAS study. he key advancement here was to place the nanorods in an ordered array. lson says the array setup allowed her to tune the pixel s color in two

Olson s five-micron-square pixels are about 40 times smaller than the pixels used in commercial LCD displays.

To make the pixels she used aluminum nanorods that each measured about 100 nanometers long by 40 nanometers wide.

She used electron-beam deposition to create arrays regular arrangements of nanorods in each pixel.

She was able to fine-tune the color produced by each pixel by using theoretical calculations by Rice physicists Alejandro Manjavacas a postdoctoral researcher

and Link say the research team hopes to create an LCD display that uses many of the same components found in today s displays including liquid crystals polarizers and individually addressable pixels.

and the inherent directionality of the nanorods provides another advantage. ecause the nanorods in each array are aligned in the same direction our pixels produce polarized lighthe says. his means we can do away with one polarizer in our setup

which was developed at UC Berkeley works by adjusting the intensity of each direction of light that emanates from a single pixel in an image based upon a user s specific visual impairment.

The way they continue to improve is by making huge pixel mosaics which is appropriate for many

filters directly onto the pixels. The new design enables smaller less complex and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors

Every 3d-Pixel (or"Trixel""as the team calls them) used by the prototype system consists of lasers

On the downside, the current prototype only has a resolution of five pixels by three and,

"But the crucial point is that the individual laser pixels work. Scaling it up to a display with many pixels is not a problem."

"From first design to working prototype took three years, and the technology behind the system has now been patented.

when they thought only pixels were present. The reason for this success is pretty straightforward.

In spite of the declared determination of most publishers to pivot from print to pixels, the industry s share of the digital advertising market has plunged by more than 50%.

and overall digital data are from the Interactive Advertising Bureau. While newspaper publishers are continuing to gain audience at their web and mobile sites,

and terabytes of data on their yields. By adding these to the Climate Corporation soil-and-weather database,

All it needs is a resolution of at least 40 by 40 pixels. Smile Secrets: 5 Things Your Grin Reveals About You Using Facet on a video sequence produces even more interesting results

In these types of cases the software does need images clearer than 40 pixels but the required resolution is still within a common webcam's capabilities.

#Camera shoots and compresses image in one go Today s cameras take images as'raw'arrays of pixels,

which can take up many megabytes of storage, and then use data-compression algorithms such as JPEG to store the image in a smaller file."

In 2006 Baraniuk and his colleagues made the first optical camera that produced multi-pixel images with a single-pixel sensor.

Goldman s group developed a more complex cipher in which every byte#a string of eight ones

400 to encode every megabyte of data, and $220 to read it back. However, these costs are falling exponentially.

Stanford university researchers are in the early stages of developing self-powered retinal implants where each pixel in the device is fitted with silicon photodiodes.

Existing 3d-display technologies tend to have larger pixel sizes and therefore operate better at distances of a few metres,

But the pixels in that case tend to be larger he explains, because it is difficult to produce small lenses of high optical quality.

In a series of hour-long experiments, each of which generated 1 terabyte (1 million megabytes) of data,

The researchers say that the wireless BCI is able to stream thought commands via its radio at a rate of 48 megabits per second, about the speed of a home Internet connection.

and other aberrations. he exciting part is that this approach can acquire data at the same high speed per pixel as conventional microscopy,

000 times slower per pixel, says George Church, a professor of genetics at Harvard Medical school who was not part of the research team.

The light waves can carry data at 300 megabits per second from LED fixtures to wireless devices.

Because it is always possible to modify a digital image you need strong archiving procedures plus information on

pixels are illuminated by a white LED backlight that passes through blue, red, and green filters to produce the colors on the screen.

With more light shining through the pixels, LCD TVS equipped with Color IQ produce 100 percent of the color gamut,

Putting pixels in the room G-speak has its roots in a 1999 MIT Media Lab project co-invented by Underkoffler in Professor Hiroshi Ishii Tangible Media Group called uminous Room,

which enabled all surfaces to hold data that could be manipulated with gestures. t literally put pixels in the room with you,

They also assigned pixels three-dimensional coordinates. Imagine, for example, if you sat down in a chair at a table,

and this much in front of me, among other things, Underkoffler explains. e started doing that with pixels.

nd the pixels surrounded the model, Underkoffler says. This provided three-dimensional spatial information, from which the program casted accurate, digital shadows from the models onto the table.

shared-pixel workspace has enormous value no matter what your business is. Today, Oblong is shooting for greater ubiquity of its technology.

That corresponds to five thousandths of a pixel in a close up image, but from the change of a single pixel color value over time,

it possible to infer motions smaller than a pixel. Suppose, for instance, that an image has a clear boundary between two regions:

Everything on one side of the boundary is blue; everything on the other is red.

If, over successive frames of video, the blue region encroaches into the red region even less than the width of a pixel the purple will grow slightly bluer.

Putting it together Some boundaries in an image are fuzzier than a single pixel in width, however.

The difficulty with this approach is that simulating a single pixel in the virtual image requires multiple pixels of the physical display.

So the physical pixels projecting light to the right side of the pupil have to be offset to the left

and the pixels projecting light to the left side of the pupil have to be offset to the right.

The use of multiple on-screen pixels to simulate a single virtual pixel would drastically reduce the image resolution.

The algorithm that computes the image to be displayed onscreen can exploit that redundancy allowing individual screen pixels to participate simultaneously in the projection of different viewing angles.

In the researchers prototype however display pixels do have to be masked from the parts of the pupil for which they re not intended.

Spreading pixels Oliver Cossairt, an assistant professor of electrical engineering and computer science at Northwestern University, once worked for a company that was attempting to commercialize glasses-free 3-D projectors. hat

which is what projection optics does moved essentially the pixels away from each other, Cossairt continues. hat allowed them to break this invariance

#3-D images with only one photon per pixel Lidar rangefinders which are common tools in surveying

and Computer science and lead author on the new paper explains the very idea of forming an image with only a single photon detected at each pixel location is counterintuitive.

The way a camera senses images is through different numbers of detected photons at different pixels Kirmani says.

each location in the grid corresponds to a pixel in the final image. The technique known as raster scanning is how old cathode ray tube-tube televisions produced images illuminating one phosphor dot on the screen at a time.

It guides the filtering process by assuming that adjacent pixels will more often than not have similar reflective properties

"Kadambi says. hat is because the light that bounces off the transparent object and the background smear into one pixel on the camera.

and returns to strike the pixel. Since the speed of light is known, it is then simple for the camera to calculate the distance the signal has travelled

and Dust environment Explorer (LADEE) spacecraft had made history by using a pulsed laser beam to transmit data over the 239000 miles from the moon to Earth at a record-breaking data-download speed of 622 megabits per second (Mbps). This download speed is more than six times faster than the speed achieved by the best

In one night, the cars can generate more than 3 terabytes of data, which is downloaded to an onboard system and processed at the startup Boston headquarters.

In these arrays each pixel was an 800-nanometer-long square containing four aluminum nanodisks.

Consequently by varying the diameter of the four aluminum nanodisks in a pixel (all four nanodisks having the same diameter) the scientists were able to produce about 15 distinct colors#a good start

(but keeping all four diameters within a pixel the same) and the spacing between adjacent nanodisks in a pixel (see image).

or colors of light within the same pixel researchers have developed a new method for making 3d color prints.

Each pixel can exhibit one of two colors depending on the polarization of the light used to illuminate it.

So by viewing the pixels under light of both polarizations two separate images can be seen.

We have created possibly the smallest-ever stereoscopic images using pixels formed from plasmonic nanostructures Yang told Phys. org.

For example a 130-nm x 190-nm elliptical pixel appears green under y-polarized light

Comparing the two pixel shapes the researchers found that the elliptical pixels have a broader range of polarization-dependent colors

while the nanosquare dimer pixels have lower levels of cross-talk minimizing unwanted mixing of colors.

The researchers also note that it's possible to make pixels that can encode not just two but three or more images in a single pixel.

pixels are illuminated by a white LED backlight that passes through blue, red, and green filters to produce the colors on the screen.

With more light shining through the pixels, LCD TVS equipped with Color IQ produce 100 percent of the color gamut,

#First graphene-based flexible display produced A flexible display incorporating graphene in its pixels'electronics has been demonstrated successfully by the Cambridge Graphene Centre and Plastic Logic,

however cameraphone technology needs to support it in ways it currently doesn t. Cameraphones have improved dramatically in the last few years the Nokia Pureview sensor has 41 megapixels

and HTC s newest sensor has larger pixels that grab more light but they still suffer from one great shortfall:

The individual beams are created the same way pixels on a projector are. There's a semiconductor chip that has an array of a million tiny mirrors on it.

The mirrors flip to modulate each pixel's brightness. This way the system can turn off some beams sometimes without the driver noticing too much.

They designed a pixel that can not only measure incident light but also convert the incident light into electric power.

At the heart of any digital camera is an image sensor, a chip with millions of pixels.

The key enabling device in a pixel is the photodiode, which produces an electric current when exposed to light.

This mechanism enables each pixel to measure the intensity of light falling on it. The same photodiode is used also in solar panels to convert incident light to electric power.

The photodiode in a camera pixel is used in the photoconductive mode while in a solar cell it is used in the photovoltaic model.

Nayar, working with research engineer Daniel Sims BS'14 and consultant Mikhail Fridberg of ADSP Consulting, used off-the-shelf components to fabricate an image sensor with 30x40 pixels.

each pixel's photodiode is operated always in the photovoltaic mode. The pixel design is very simple,

and uses just two transistors. During each image capture cycle, the pixels are used first to record

and read out the image and then to harvest energy and charge the sensor's power supplyhe image sensor continuously toggles between image capture and power harvesting modes.

and for every column of pixels, generates an associated sound with a frequency and volume that depends upon the vertical location and brightness of the pixels.

A large number of bright pixels at the top of a column would translate into a loud, high-frequency sound,

whereas a large number of lower dark pixels would be a quieter, lower-pitched sound. A blind person wearing this camera on a pair of glasses could then associate different sounds with features of their environment.

HEAR A SOUND, SEE A COLOR IN the trials, sighted people with no training or instruction were asked to match images to sounds;

The discovery by the Rice university lab of chemist James Tour could allow for crossbar array memories that store up to 162 gigabits

Eight bits equal one byte; a 162-gigabit unit would store about 20 gigabytes of information.

Details appear online in the journal Nano Letters. Like the Tour lab previous discovery of silicon oxide memories, the new devices require only two electrodes per circuit,

while at the same time the NCI's tiny size just 300 microns across in their 16-pixel proof of concept makes possible incorporation into even very small devices.

The current limitation of 16 coherent pixels did not stop the researchers from imaging the front face of an American one-cent coin from half a meter (1. 5 ft) away with a method that scanned in four

The sensor's pixels measure 19 microns, which is more than five times larger than those generally found in high-end DSLRS and amounts to a modest 2. 26 megapixels.

Canon has made efforts to stave off the inevitable noise that will accompany such an insanely high ISO with
