New Technology-AI in hospitals to maintain staff hygiene

New Technology-AI in hospitals to maintain staff hygiene

ENEVA: Scientists have developed a new artificial intelligence system that can track medical staff through cameras and detect whether they maintain proper hand hygeine, an advance that could reduce the risk of hospital- acquired infections.

Researchers at the Swiss Federal Institute of Technology (EPFL) conducted a study using a combination of depth cameras and computer-vision algorithms.

They tracked people around two hospital wards and automatically identified when they used gel dispensers.

"We're trying to shed light on the dark spaces of healthcare. Understanding the problem is just the first step," said Alexandre Alahi from EPFL.

In the initial study, researchers collected images from cameras installed overlooking corridors, patient rooms and alcohol-based gel dispensers, among other places.

Of the 170 people they recorded entering a patient's room, only 30 people correctly used the gel dispensers.

The team then used 80% of the images to train their algorithms to detect healthcare staff, track them as they move from one spot to another across different cameras, and monitor their hand hygiene behaviour.

New Technology-robot can follow pedestrian traffic rules

New Technology-robot can follow pedestrian traffic rules Engineers at Massachusetts Institute of Technology (MIT) have designed an autonomous robot that can keep pace with foot traffic while observing the general social codes that pedestrians follow to avoid oncoming obstacles while keeping up a steady walking pace. In drive tests, the robot, which resembles a knee-high kiosk on wheels, successfully avoided collisions while keeping up with the average flow of pedestrians, said the researchers who have detailed their robotic design in a paper scheduled to be presented at the IEEE Conference on Intelligent Robots and Systems to be held in Vancouver, Canada, in September. "Socially aware navigation is a central capability for mobile robots operating in environments that require frequent interactions with pedestrians," said lead author of the study Yu Fan (Steven) Chen. "For instance, small robots could operate on sidewalks for package and food delivery. Similarly, persona...

New Technology-New system can reconstruct faces using your DNA

New Technology-New system can reconstruct faces using your DNA Scientists have reconstructed faces from people's DNA, an advance that challenges the idea that genetic databases can be anonymous. Research institutions regularly collect thousands of human genomes to understand diseases. Most promise volunteers that their identity will be protected. However, the study published in the journal Proceedings of the National Academy of Sciences shows that in the long run, such anonymity may not be possible. By training an algorithm to link genetic information with facial features and voices, researchers were able to identify people from their genomes. "The genome contains all the information that determines your identity. It is used in criminal courts around the world to identify people," said Craig Venter, from the US-based company Human Longevity Inc. Given a sample of ten people, researchers were able to match headshots with the genome 80% of the time. The system was trained...

New Technology-Discovered a new method to convert dried tree leaves

New Technology-Discovered a new method to convert dried tree leaves Scientists have discovered a new method to convert dried tree leaves into a porous carbon material that can be used to produce high-tech electronics. Researchers from Qilu University of Technology in China used a multi-step, yet simple, process to convert phoenix tree leaves into a form that could be incorporated into electrodes as active materials. The dried leaves were first ground into a powder, then heated to 220 degrees Celsius for 12 hours. This produced a powder composed of tiny carbon microspheres. These microspheres were then treated with a solution of potassium hydroxide and heated by increasing the temperature in a series of jumps from 450 to 800 degrees Celsius. The chemical treatment corrodes the surface of the carbon microspheres, making them extremely porous. The final product, a black carbon powder, has a very high surface area due to the presence of many tiny pores that have been chemically etched on...
