Engineers at Japan’s Saitama University have devised a wheelchair capable of following a caretaker accompanying the patient, eliminating the need for manually carting the wheelchair.

The person accompanying the wheelchair wears a radio beacon that transmits a continuous pulse of signals that are detected by motion sensors on the wheelchair. Using these sensors, the wheelchair follows behind or besides the person guiding it.

Applications are abundant in highly congested healthcare installments where caretakers are required to handle more than one wheelchair simultaneously. The technology can be used to program multiple wheelchairs that can follow a single person guiding them with ease.

A new Android app claims to transform your phone into a heart rate monitor on the go, using only the built-in camera and flash on your phone.


Instant Heart Rate is an innovative app available on the Android Market that uses minute colour changes on your fingertip to measure your heart rate. It measures the oxygen saturation changes in your blood. On every heart beat, your blood becomes more oxygen rich which causes a slight change in the colour of your skin. The camera in your mobile tracks those changes and calculates your heart rate. Its functioning is similar to a pulse oximeter, though without a dedicated light source.


The app is currently available only for Android phones, but could be designed for a wider range of platforms in the future.

Weeks pass by without attending a single lecture,
Where we go to sleep & mark the attendance register,
I just couldn't study for marks and grades,
Memorize theorems for degrees and certificates.


The defaulter's meeting was often a delight,
Seldom did it cause my friends a worrisome plight,
I knew where my time had gone but they did not,
Though everyone had an excuse to handle this plot.

I can't promise next sem, that I would attend,
To sit in the lecture and seem to pretend.
I know what you taught was archaic and out-dated, 
Inspite hiking the fees on branding the institution as top-rated.


We all had dreams of becoming good engineers,
Dreams being an expression of EEG and neurotransmitters,
''It has a lot of scope!'' was heard loud and clear,
But for many, the end turned to be a carcinogenic pap smear.


I could not accept software engineering as my future,
And it’s not that I am inferior or superior ,
It's just because I am a Biomedical Engineer.


They wake up every morning hearing shrill audible shock, (They=software engineers)
Disturbing and working against their circadian clock,
They curse their day and long hours at work,
Still continuing it regularly, for a huge perk.


Finance was always my last resort,
Something as easy as a blind-folded shot,
But then came a process of cardiac re-engineering,
Where my heart clearly said "Finance: You are not winning!"


I can't do something that I don't love,
In a field where I don’t want my cognizance to serve,
And not that I am inferior or superior,
It’s just because I am a Biomedical engineer.


A faulty conscience can kill you faster,
Than the phenomenon of gradually getting older,
As life continues to last, till you will,
It’s unfortunate to see people; who eventually kill.


I believe self-killing could be mechanical or mental,
And living your life without your family is insubstantial,
And not that I am inferior or superior,
It’s just because I am not a mechanical but a Biomedical Engineer.


People end up doing things mechanically,
Achievements are always classified superficially,
Passion is over -written by materialistic goals,
Evoking artificial neural signals into their souls.


I just can't write this poem any further.
And Its not that I am inferior or superior,


It’s just because I am a Biomedical Engineer.
