The Electrowetting Display

Electrowetting displays are just as capable as the liquid crystal displays in tablets and notebooks, but they are three times more efficient. Johan Feenstra, who heads Samsung's electronic display research center in the Netherlands, explains how they work.

Bright, full color e paper under development by Ricoh

This e-paper is currently under development by Ricoh.

It has a unique structure, with layers of a new electrochromic material that turn magenta, yellow, and cyan from their transparent state. In this way, Ricoh's e-paper enables a bright, full-color display, like ordinary paper, which hasn't been possible with e-paper until now.

This prototype is a 3.5-inch, QVGA display, with a pixel density of 113.6 ppi. Its reflectivity is 70%. Compared with current color-filter displays, this e-paper is 2.5 times brighter. It has a color reproduction range of 35%, higher than that of a newspaper, which is 31% in Japan.

"To produce colors, CMY subtractive mixing is ideal, and that's the model used in printing. We've implemented this by coating the panel with layers of yellow, magenta, and cyan. Ordinarily, if you try to use layers like this, you need an electrode driver for each layer. But in this display we're developing, the electrodes are active TFTs. So, we can achieve all colors with a single TFT, by switching the electrodes on the display side."

The material used for the chromic layers is transparent in its oxidized state, but becomes colored when it's reduced. To achieve a color display, rewriting is done three times in the order magenta, yellow, cyan. As the spaces between the electrochromic layers are narrow, at about 2 microns, the result is an ideal color-mixing display.

"The stage we're at right now is, we're checking that this model works with an actual active panel. Regarding the color drive, we haven't refined this yet, so switching takes over a second for each color. But the reaction speed of the chromic material is, ideally, about 100 ms."

"From now on, we'd like to increase the size to 6 inches, then 10 inches. We also want to work on achieving stable driving and faster response."

Brion Vibber has been working on ogv.js, an Ogg video player in JavaScript, supporting both audio and video. We've seen video codecs in JavaScript before, such as Broadway (H.264),Route9 (WebM/VP8), and more but mostly without audio support to go along with it. We have audio codecs in JS too, just not combined with video yet. That changes with ogv.js.

Augmented Pixels: Indoor Navigation Platform for Drones

Drones are notoriously difficult to handle indoors: hard to control and prevent crashing into walls or people.

Augmented Pixels has been actively developing technology (including SLAM) to ensure safe flights as well as intuitive and easy navigation using Augmented Reality.

They came up with a platform that significantly reduces accident rates and minimizes the effect of "human factor". Moreover, it is possible to program the drone to fly around and land by itself.

The prospects for this technology include a wide range of use cases (e.g. inspection of premises for security, creation of 360-degree tours, etc.).Augmented Pixels is located in Palo Alto, CA.

Tiny 3D Camera Offers Brain Surgery Innovation

http://www.jpl.nasa.gov/news/news.php?feature=4702

Harish Manohara, principal investigator of the project at JPL, working in collaboration with surgeon Dr. Hrayr Shahinian at the Skull Base Institute in Los Angeles, who approached JPL to create this technology.

MARVEL's camera is a mere 0.2 inch (4 millimeters) in diameter and about 0.6 inch (15 millimeters) long. It is attached to a bendable "neck" that can sweep left or right, looking around corners with up to a 120-degree arc. This allows for a highly maneuverable endoscope.

“Multi-Angle and Rear Viewing Endoscopic tooL” (MARVEL) denotes an auxiliary endoscope, now undergoing development, that a surgeon would use in conjunction with a conventional endoscope to obtain additional perspective.

To operate on the brain, doctors need to see fine details on a small scale. A tiny camera that could produce 3-D images from inside the brain would help surgeons see more intricacies of the tissue they are handling and lead to faster, safer procedures.

An endoscope with such a camera is being developed at NASA’s Jet Propulsion Laboratory in Pasadena, California. MARVEL, which stands for Multi Angle Rear Viewing Endoscopic tooL, has been honored this week with the Outstanding Technology Development award from the Federal Laboratory Consortium. An endoscope is a device that examines the interior of a body part.

“With one of the world’s smallest 3-D cameras, MARVEL is designed for minimally invasive brain surgery,” said Harish Manohara, principal investigator of the project at JPL. Manohara is working in collaboration with surgeon Dr. Hrayr Shahinian at the Skull Base Institute in Los Angeles, who approached JPL to create this technology.

MARVEL’s camera is a mere 0.2 inch (4 millimeters) in diameter and about 0.6 inch (15 millimeters) long. It is attached to a bendable “neck” that can sweep left or right, looking around corners with up to a 120-degree arc. This allows for a highly maneuverable endoscope.

Operations with the small camera would not require the traditional open craniotomy, a procedure in which surgeons take out large parts of the skull. Craniotomies result in higher costs and longer stays in hospitals than surgery using an endoscope.

Stereo imaging endoscopes that employ traditional dual-camera systems are already in use for minimally invasive surgeries elsewhere in the body. But surgery on the brain requires even more miniaturization. That’s why, instead of two, MARVEL has only one camera lens.

To generate 3-D images, MARVEL’s camera has two apertures — akin to the pupil of the eye — each with its own color filter. Each filter transmits distinct wavelengths of red, green and blue light, while blocking the bands to which the other filter is sensitive. The system includes a light source that produces all six colors of light to which the filters are attuned. Images from each of the two sets are then merged to create the 3-D effect.

Now that researchers have demonstrated a laboratory prototype, the next step is a clinical prototype that meets the requirements of the U.S. Food and Drug Administration. The researchers will refine the engineering of the tool to make it suitable for use in real-world medical settings.

In the future, the MARVEL camera technology could also have applications for space exploration. A miniature camera such as this could be put on small robots that explore other worlds, delivering intricate 3-D views of geological features of interest.

“You can implement a zoom function and get close-up images showing the surface roughness of rock and other microscopic details,” Manohara said.

“As a skull base surgeon with a specific vision of endoscopic brain surgery, it has been a privilege and a great personal honor working with the JPL team over the past eight years to realize this project,” Shahinian said.

MARVEL is being developed at JPL for the Skull Base Institute, which has licensed the technology from the California Institute of Technology. JPL is managed for NASA by Caltech.
