Traffic jams and ambulances.

What is an ambulance?

An ambulance is a vehicle for transportation of sick or injured people to, from or between places of treatment for an illness or injury.

But imagine you call 911 and tell the operator you are experiencing the signs of a heart attack -- chest discomfort, shortness of breath and nausea. EMS employees arrive and help you into an ambulance, bound for the best, nearest emergency department, you think, until you overhear on the radio that it is closed to traffic.

Well that is horrifying!

What to do then?

Clear traffic using a wand! ......................................Bad idea.

Instead take some new preventive measures along with the earlier existing ones and this problem can be eradicated.Yes its possible!

How?

In this post i am going to suggest some ways that i believe can work out perfectly if given proper attention.

These mostly are the amalgamation of modern technology,kinematics,coordination and hope.The overview of the concept is to regulate the traffic in order to allow the ambulance to pass unhindered.

Assumptions made

•  Distance between two signals                   = 500m
• Type of crossing                                       = 4 lanes
• Speed of ambulance                                 = 40 kmph
• Speed of other cars                                  = 20 kmph
•  Avg. length of cars and ambulance           = 3m
• Avg. width of cars and the ambulance       = 1.5m
• Distance between consecutive vehicles      = 1m
• Width of road                                           =14m

1. Install proximity sensors in all vehicles(most 4 wheeler ) and on signals.
2. Whose switch is to be provided inside the ambulance.
3. In this case we have assumed road to be double laned and and crossing of lane "+" type.
4. Ambulance must act as point source moving and activating LEDs of sensors in the cars.

Working

Whenever an ambulance will pass through a traffic signal ,the signal will be forwarded to other nearby signal(at 500m) and the crossing would be closed only allowing the road on which ambulance is travelling to pass through.

As soon as ambulance pass through the second signal it will get opened closing the the third signal in a similar way .Thus this process would be repeated accurately till the ambulance reaches the hospital.

You might be wondering by now what is the use of sensors in the cars?!Well it is because people should be made aware of ambulance's arrival.

So next question is "are sirens not enough"? Sirens are effective but it is possible its effect go unnoticed as in case of heavy drilling work going nearby or continuous honking by other vehicles.But when there would be LEDs lighting up inside the car ,the driver will definitely lay his/her attention towards it and change the lane.

This is because those LEDs wold meant only for ambulances!!

Next question on the trot would be what should be the minimum distance between the ambulance and last car sensing its arrival .Will all cars of the city will lighten up whenever any ambulance would pass??!!

Well again that sounds absurd! Keeping all the factors in mind (like distance between two cars , cars' length and width and speed) a car  will take nearly 2.5 seconds  to change over to other lane.

And keeping that duration of time in mind the last car coming inside the circle would be at a distance of nearly 40 meters

To make my statements sound i underwent some calculations which i will publish in my next post.

CRICKET MY FIRST LOVE

CRICKET MY FIRST LOVE

Well hello everyone once again , this time it’s not about my photography or physics or anything, but this time round I would like to share my experience with the sport named “CRICKET”.

I still remember when I was around 6 years old  I got my first cricket bat. It was actually a “mogri” one which is used by Indians to wash clothes  :P but nonetheless it was precious for me .I used to play with my father and surprisingly my dog too! Let me tell you my dog  was splendid  during fielding.

I am not sharing this to show what trophies or tournaments I have won, in fact I have won none . But its my unbiased love towards the game that I am writing .And by reading this any sport lover could relate yourselves quite easily.

Being an Indian fan, I was a die hard fan of SRT(Sachin ramesh tendulkar), I wrote “was” because he retired from the game for almost 6 months now. I still remember it was the World cup of 2003 when I first got to know how exciting the game can be. In that W.C few things happened like I got the know about the rules of the game coz earlier I used to take my bat back once I got out ,later realizing it was not allowed :P . Even under the guidance of my grandpa and dad I learned to see the score of the undergoing match and infinite etc!

Sadly India lost to Australia in the finals but it was enough for “cricketing passion” to reach its peak.

During that world cup 2 aussie players became my idols namely, Glenn McGrath and Brett Lee (both bowlers by the way).Their deliveries were so fast and accurate that any reckless shot by the batsman was finally turned out to be a wicket. So I thoroughly enjoyed bowling from my 6^th grade onwards!!

There was a inter-class match where I took 4 wickets in an over , and I’ll brag that no matter  what. :D

During that time our house shifted , landing me in the locality of cricketing buffs! They were guys of my age (10-15 yrs).We used to play every weekend and don’t ask what used to happen during vacations?!

I’ll tell you the schedule

·         Waking up – 6:00 AM

·         Getting to the field –6:30 AM

·         Warm ups – half hour (god knows what warm up exercises we did :P but still…)

·         Session 1 of play – 7:00AM – 12PM

·         HOME (scolding time/MOM) – 12PM – 1PM

·         TV(Old cricket matches if no lives going on) – 1PM – 2:30 PM

·         Scolding time/dad – 2:30PM – 3:30PM

·         Escaping to the field (once parents fell for afternoon nap) – 4:00 pm

·         Session 2 of play – 4:30 PM – 7:30 PM

#period

In those days for after any good results or birthdays I demanded on cricketing stuffs!

Ranging from 4bats,2leather balls, gloves, pads ,helmet to lower abdomen guard ( I still don’t remember I’ve ever used it).

One day during my exams my father dragged me to the home from the field because of bunking studies.

That incident deepened my love towards it( it got nearly 90% that year :P ).

So this happened for like 5-6 years until I came to 11^th grade .I was sent to other town for studies .That time I was undesirably kept out of the game .Let it be not watching a match due to lack of entertainment or not playing a match for almost 2.5 years I felt terrible. Even when I wanted to no one did(geeks!).But every time shall pass. I finally got into a prestigious university with good grades ( still wondering how..) and got back to the game with 200% energy.

Playing whenever getting time between lectures and sharpening bowling skills are a part of my daily schedule. And let me tell you can’t face my bowling that easily ;) even though my idols got retired my passion hasn’t.

I am in third year now and loving the game like never before especially after India wining the 2011 WORLD CUP almost after 28 years.!!!

Projection Welding using xpandrel technique (PowerPoint view)

DUST COLLECTOR

Introduction – Once the full welding of coils are done, they are subjected to various tests which ensures that following operations namely projection welding, bending and full welding are performed accurately and the coil will then be sent for Radiography testing.

These tests includes:

·         Ball test.

·         Hydraulic test.

In ball test,a metallic ball of diameter same as that of internal diameter of the coil’s pipe is passed via pneumatic process i.e. passing compressed air through the pipe. This process ensures that the bends are perfect.

But it has been observed that huge amounts of dust get generated from the pipes. To eradicate the above mentioned problem we developed a device and named it as DUST COLLECTOR.

MANUFACTURING FLOW PROCESS –

We started with searching used metallic cans which are being used for painting coil modules. So after finding them we cleaned them with the help of thinner for removing inner solidified paint. After that our next aim was obtaining PVC(polyvinyl chloride) pipes and an accurate hole(diameter same as that of pvc pipe) was made on the lid of the can. Now one end of pvc pipe was inserted into the can(which is filled with water) and other end is fitted to a piece of pipe. Now the successive end of m/s pipe was calibrated with a butt joint clamp. The clamp acts as a junction between the dust collector and the coil.

Now for pipes/coils of different diameter we use butt-joint clamps of same diameters as well. Now when the compressed air is passed , the dust gets collected into the dust collector and we must ensure that the lid of the can is perfectly sealed which inturn prevent sudden splash of water coming out of the water filled can.

FURTHER MODIFICATIONS-

Since the container in dust collector is completely sealed, passage of high pressure compressed air can act as a potential threat because the pressure is around 10 bar. To nullify the threat we provided a vent in the form of of a bent tube welded and attached at the top of the collector .This tube is TIG welded with high precision on the lid.
