Say Sayonara to Blurry Pics

November 22, 2005

A computer science Ph.D. student at Stanford University has outfitted a 16-megapixel camera with a bevy of micro lenses that allows users to take photos and later refocus them on a computer using software he wrote.

Ren Ng’s camera pits about 90,000 micro lenses between the main lens and sensor. The mini lenses measure all the rays of incoming light and their directions of origin. The software later adds… read more

Scaling Up a Quantum Computer

August 7, 2009

Researchers at the National Institute of Standards and Technology (NIST) in Boulder, CO, have demonstrated multiple computing operations on quantum bits–a crucial step toward building a practical quantum computer.

Scalp-implanted chip for deep brain stimulation developed

June 29, 2010

An experimental chip that could one day provide therapeutic deep brain stimulation (DBS) for drug resistant epilepsy and other conditions has been developed by Tel Aviv University researchers.

The Rehabilitation Nano Chip (ReNaChip) is implanted under the scalp and connects to DBS electodes implanted in the brain of animal models to rehabilitate motor-learning functions lost due to brain damage. The researchers hope that as chips become smaller, the ReNaChip… read more

Scan anything and let your phone do the rest

October 26, 2011
Digimark

DigimarcĀ  has developed Discover, a free iOS and Android app that uses a smart phone’s camera and microphone to “capture” a sample of audio or an image, barcode, or QR code, then identifies it through Digimarc’s database and searches for related material online.

As of yet, this system is only implemented by a small number of publications. It requires “digital watermarks” to identify images and video.

Scan ‘shows if people trust you’

April 6, 2005

MRI brain scans of volunteers playing a money game showed that a brain region called the caudate nucleus lights up when it receives or computes data to make decisions based on trust.

Scanadu Scout ‘Tricorder’ launches on indiegogo

Scanadu has announced updates to its Scanadu Scout, the “first medical Tricorder,” a prototype device designed to measure vital signs; and the launch of anĀ indiegogo campaign.

A first-edition Scout can be reserved on indiegogo and will be available in March 2014.

The Scout is sold as an exploratory tool. “By helping us collect data, we can file our application to the FDA for market… read more

Scandinavian scientists designing robotic snakes

June 26, 2008

The Sintef Group of Trondheim, Norway is designing a robot modeled on snakes to inspect and clean complicated industrial pipe systems that are typically narrow and inaccessible to humans.

The intelligent robots have multiple joints to enable them to twist vertically and climb up through pipe systems to locate leaks in water systems, inspect oil and gas pipelines, and clean ventilation systems.

Scanner ‘reads minds’ to spot early signs of dementia (article preview)

November 4, 2008

New software helps non-specialists diagnose dementia from PET scans by comparing a scan of activity levels in a patient’s brain — revealed by the rate at which the brain takes up a radioactive glucose substitute that shows up on the scan — with a database.

Scanning with robots

March 15, 2005

Engineers at Imperial College’s mechatronics in medicine laboratory are developing a robot system to allow more accurate biopsies to be taken within the cramped conditions of an MRI chamber.

The extremely strong magnetic fields generated by MRI scanners rule out the use of motors to operate the robot. So the team is investigating the use of piezo-ceramic actuators, which deflect when a voltage is applied to them, allowing them… read more

Scanning your home with kinect could improve 3D robot vision

August 29, 2012

kinect-at-home

Seeking a way to crowdsource better computer vision, roboticists have launched a website that allows users to record pieces of their environments in 3-D with a Kinect camera, Wired Science reports.

Called Kinect@Home, the open-source and browser-based effort remains in its infancy. Users have uploaded only a few dozen models of their living room couches, kitchen countertops and themselves.

Should the project catch on,… read more

Scanning Your Money to the Bank

February 8, 2008

Fiserv, the big transaction services company, has announced new software that will enable banks to let home users deposit checks by scanning them.

Scans of brain networks may help predict injury’s effects

March 24, 2010

Clinicians may be able to better predict the effects of strokes and other brain injuries by adapting an MRI scanning method called “resting-state functional connectivity” (FC), which assesses the health of brain networks that let multiple parts of the brain collaborate.

ScanSoft updates voice software

May 19, 2004

ScanSoft has announced a new version of its OpenSpeech Recognizer software with improved natural-language capabilities that lets users speak in full sentences, improves name recognition, and recognizes 40 languages.

The software also has learning capabilities, so it gets better at recognizing and interpreting an accent the more it encounters it.

Scarcity of new energy minerals will trigger trade wars: geologists

November 2, 2010

A lot of rare metals are needed to make photovoltaic panels, rare earth magnets for wind generators, fuel cells and high-capacity batteries for hybrid and electric vehicles. But most industrialized nations, including the United States, are almost entirely dependent on foreign sources for those metals. The only way this is going to change is if there is more domestic exploration and mining, say geologists.

“There’s a misunderstanding in the… read more

Schizophrenia as Misstep by Giant Gene

April 18, 2006

Researchers have made progress in understanding how a variant gene, neuregulin-1, linked to schizophrenia may exert its influence in the brain.
