Robotic walking stick for visually impaired
New York: In a first, engineers have
designed a robotic walking stick for the visually impaired that can detect the
user's immediate path and store localised geographical information.
The robotic cane has two cameras and
Bluetooth audio functionality.
The cameras
detect objects in the user's path, such as chairs and stairs, while the audio
system communicates to the user.
Meanwhile, a computer holds
information about recent pathways and objects within them.
"This allows the cane to
recognise the user's location and guide the user, much as a seeing-eye-dog
would do. Like a traditional cane, the robot cane is adjustable to different
lengths," explained its designer Cang Ye from University of Arkansas at
Little Rock - Engineering ERIQ Lab.
The
technology has been prototyped under the National Robotics Initiative, funded
by the US National Science Foundation and National Institutes of Health, Live
Science reported.

WHO ensures 'best care' for Ebola affected health
workers
Geneva: The World Health
Organisation (WHO) on Sunday ensured that it will provide best care to its
Ebola-affected health workers in Sierra Leone as possible, including the option
of medical evacuation to another care facility if necessary.
Nearly 400 people from across the
organisation and from partners in the Global Outbreak Alert and Response
Network has been deployed by WHO to help respond to the disease in four west
African countries, since the beginning of the international response to the
outbreak in March, as reported by Xinhua.
Ebola
virus is spread through contact with bodily fluids and people giving care or
working around infected patients are known to be a high-risk group, according
to WHO.
Britain has evacuated its national,
who contracted the Ebola virus in Sierra Leone, by flying him back to Britain
on a Royal Air Force jet.
The unidentified patient, who worked
as a healthcare worker, had tested positive for Ebola virus infection last week.
As many as 113 new cases of Ebola
virus disease as well as 84 deaths were reported from Guinea, Liberia, Nigeria
and Sierra Leone last week, WHO said.
In Guinea, where the epidemic
started, the toll is 406 while in Sierra Leone, 392 have succumbed to the
haemorrhagic fever. Five deaths have been witnessed in Nigeria so far.
In
December 2013, an outbreak of Ebola virus disease began in Guinea, leading to
an epidemic in West Africa after it spread to Liberia, Sierra Leone and
Nigeria.
