Smell-o-Vision is finally here

April 1, 2013

smelling_screen

Smell-O-Vision was a system that released odors during the projection of a film so that the viewer could “smell” what was happening in the movie.

Now the “smelling screen,” invented by Haruka Matsukura at Tokyo University of Agriculture and Technology in Japan and colleagues, makes smells appear to come from the exact spot on any LCD screen that is displaying the image of a cup of coffee,… read more

Smile, Gamers: You’re in the Picture

November 13, 2003

Sony Computer Entertainment America has released EyeToy, a miniature camera that attaches to the PlayStation 2 and translates body movements into actions in a video game.

Smithsonian turns to 3D to bring collection to the world

March 1, 2012

The Smithsonian is using laser scanners and 3D printers to create “digital surrogate” models, exhibits, and scientific replicas of many of 137 million physical objects in its collection.

The museum also hopes to make its digital 3D models publicly available.

 

Smoking ‘triggers deadly changes’

May 15, 2008

Oregon Health and Science University researchers have identified a key mechanism by which smoking triggers genetic changes that cause lung cancer.

Cigarette smoke slows production of the FANCD2 protein in lung cells. FANCD2 plays a key role in repairing damage to DNA and causes faulty cells to commit suicide before they go on to become cancerous.

Snake design inspires improved search-and-rescue robots

January 23, 2012

Georgia Tech researchers have designed a new all-terrain robot by studying the locomotion of snakes.

Designing an all-terrain robot for search-and-rescue missions requires a machine that is flexible enough to move over uneven surfaces, yet not so big that it’s restricted from tight spaces.

It might also be required to climb slopes of varying inclines. Existing robots can do many of these things, but… read more

Snake-like Robot And Steady-hand System Could Assist Surgeons

December 27, 2006
Steady-hand robot

Johns Hopkins University researchers are designing new high-tech medical tools to equip the operating room of the future.

A snakelike robot could enable surgeons, operating in the narrow throat region, to make incisions and tie sutures with greater dexterity and precision.

Another robot, the steady-hand, may curb a surgeon’s natural tremor and allow the doctor to inject drugs into tiny blood vessels in the eye, dissolving… read more

‘Snakebot’ navigates its way round slippery problem

December 17, 2007

Researchers have developed a control mechanism that allows a snake-shaped robot to safely navigate through an unfamiliar environment.

A number of different research groups are developing robots that mimic real snakes: their shape and simplicity make them ideal for crawling through pipes or exploring narrow or cluttered environments.

And yet, while most of these robots can crawl along and turn on command, getting them to navigate independently has… read more

Snakelike Robots for Heart Surgery

CardioArm, a snakelike surgical robot from Carnegie Mellon University, could let a surgeon performing a critical heart operation make just one incision.

The curved robot has a series of joints that automatically adjust to follow the course plotted by the robot’s head, operated using a computer and joystick. This provides greater precision than a flexible endoscope can offer.

The smallest version of the device is 300… read more

Snakes on a plane!

October 1, 2012

Snakes on a plane!

Engineers at firms like Rolls-Royce and GE are developing “snake robots” with intelligent algorithms to find and repair problems in plane engines, New Scientist reports.

The slithering simulants would be about 12.5 millimeters (1/2 inch) in diameter, controlled by a technician as they are guided through the engine’s insides, beaming back images — a bit like telesurgery, a Rolls-Royce executive said.

Finding and fixing defects in planes is currently a… read more

Snap and Search (No Words Needed)

December 21, 2009

Google’s massive data centers with their computing power and more than a billion images allow its Goggles image-recognition smartphone app to recognize millions of images.

Snapshot chat creates automatic captions

April 2, 2004

A new system that can automatically caption digital photos by listening to you and your friends chat about them is being developed by Hewlett-Packard.

PC software records these conversations, converts them to text using a speech-recognition program, and extracts keywords to caption and index the photos.

HP says the method should help organize digital files as hard drives approach terabyte levels over the next few years.

Snapshot of an electron orbital

December 16, 2004

Researchers have announced a technique to record a three-dimensional image of the orbitals of electrons in molecules.

The imaging technique uses extremely short laser pulses to briefly ionize an electron away from a molecule of nitrogen. As they spring back, the electrons emit light that can interfere with the laser pulse in different ways depending on the electron’s position and where the laser pulse hit the molecule.

Sneeze-sensing software gives avatars a good laugh

July 14, 2008

Software that can automatically recognize “non-linguistic” sounds such as laughter and generate an appropriate facial animation sequence, could improve the quality of web-based avatars or computer-animated movies.

University of Bath and University of Cardiff scientists used optical motion capture to record the facial expressions of four participants as they performed a number of laughs, sobs, sneezes and yawns. The researchers also recorded the participants’ voices during their performances. They… read more

Sniffing out terrorists

January 14, 2010

A new intelligent system to help identify terrorists carrying explosives has been developed by researchers at the Fraunhofer Institute for Communication, Information Processing and Ergonomics FKIE.

It uses a network of highly sensitive smell sensors that follow an explosive’s trail, combined with a second sensor network using laser scanners to track the route the carriers take.

Sniffling mice raise therapy hope

February 5, 2008

In a study led by London’s Imperial College, scientists have created a mouse that can catch a cold, raising hopes of new ways to treat serious respiratory conditions and asthma.

It had been thought rhinoviruses, which cause most human colds and can trigger asthma attacks, could only affect higher primates.

Rhinoviruses were discovered 50 years ago, but the failure to find a way to infect small animals had… read more
