Researchers at IIT Kharagpur Develops ‘AmbuSens’ for monitoring Hospital-bound Patients

Indian Institute of Technology, Kharagpur has developed a wireless technology called ‘AmbuSens‘ for remote monitoring of condition of those patients who are ferried in ambulances.

Salient Highlights

AmbuSens will help in wireless monitoring of various physiological conditions of patients who are ferried in ambulances. The AmbuSens system includes both hardware and software. The ambulance and the hospitals will have laptops or tablets with internet connection to continuously monitor the health condition of the patients in real-time.

The patients will be fitted with wireless body sensors. The technology will monitor the parameters like ECG, heart-rate, temperature and blood-pressure and can ensure remote monitoring of the patient’s condition even before they reach the hospital.

The web interface of the system will offer easy-to-use graphical interface with data visualisation tools such as real-time ECG graph rendering. The graphical interface can be accessed from internet-enabled laptops, tablets and smartphones. The collected patient’s data will be held confidentially.

This new system assumes significance at the backdrop of limited knowledge of medical technician who accompanies a critical patient in an ambulance. With this technology, the doctors will be able to instruct life saving medical interventions to the technician.


NASA’s Parker Solar Probe to Explore Sun’s Atmosphere

NASA’s Parker Solar Probe will be launched in the summer of 2018 to explore the sun’s atmosphere. The purpose of the launch will be to study sun’s outer atmosphere and to understand how sun works. The name of the probe initially called the Solar Probe Plus has been renamed as the Parker Solar Probe in honor of astrophysicist Eugene Parker. This is the first time NASA has named a spacecraft after a living person. 

Astrophysicist Eugene Parker published a research paper predicting the existence of solar wind in 1958. At that time, it was thought that the space between planets was a vacuum. Parker’s theory of solar wind was later on confirmed by satellite observations.

Solar wind is the flow of charged gases from the sun.

Salient Highlights

The 10-feet high Parker Solar Probe will fly within 6.4 million km of the sun’s surface right into the solar atmosphere. The probe will be subjected to brutal heat and radiation that has not experienced by any other man-made probes previously.

The objective of the mission will be to study sun in detail and shed light on Earth and its place in the solar system. The mission will work towards determining the structure and dynamics of the plasma and magnetic fields at the sources of the solar wind.

This will be NASA’s first mission to the sun and its outermost atmosphere corona. 

The mission is scheduled to end in June 2025.


ISRO’s GSLV-Mk III Launched

ISRO’s GSLV-Mk III has been launched from the Satish Dhawan Space Centre in Sriharikota on June 5, 2017. GSLV-Mk III is the heaviest rocket ever made by ISRO which is capable of carrying heavy payloads.

Salient Facts

GSLV-Mk III can put four-tonne satellites in the Geosynchronous Transfer Orbit (GTO) and is capable of placing up to eight tonnes in a Low Earth Orbit (LEO). This capacity is enough to carry a manned module and launch people into space.

The rocket has three-stages with two solid motor strap-ons (S200), a liquid propellant core stage (L110) and a cryogenic stage (C-25). The solid booster S200 is the third largest solid booster in the world. It was successfully tested at the Satish Dhawan Space Centre (SDSC), Sriharikota on January 24, 2010. The indigenously developed cryogenic upper stage, C-25, which is the most difficult component was successfully tested on February 18, 2017.

On June 5, GSLV-Mk III’s first developmental flight, D1, will place GSAT-19 satellite into space. GSAT-19 will help to improve telecommunication and broadcasting areas. This is India’s first fully functional rocket to be tested with a cryogenic engine. Cryogenic engine makes use of liquid propellants (liquid oxygen and liquid hydrogen). ISRO took about 25 years, 11 flights and over 200 tests on different components to come up with this rocket.

The rocket weighs 640-tonne which will be equivalent to the weight of 200 fully-grown Asian elephants. The rocket will be India’s heaviest but shortest rocket with a height of 43 metre.
