Wireless thoughts😇

WiTricity!!!!

Have you ever heard this word before???

During the time of my first year of Btech. , I heard this word. In my college all department have their own associations and those are the platform where to interact with seniors.at that year our association was inaugurated by a senior engineer from KSEB.he delivered an inaugural speech and mention about the power transmission. He quoted that communication technology revolution happened after the invention of wireless system and still have the opportunity to find the way to transmit electricity through wireless. Those talks gave me spark in my mind and after that program I googled how can we transmit the electricity wirelessly. That search was ended with word WiTricity.

WiTricity means wireless electricity, this word was firstly used by Massachusetts scientists, and they invented one circuit and transmitted 60 watts energy with 5 meters of distance. Which was based on the theory of eminent scientist tesla. Law of induction, our transformers and electric motors are operating on the basis of the theory of induction. Even in transformer the energy transfer from primary core secondary is by magnetic field, those principle also can be used for the wireless Technology.

From those papers, I got a decent idea about the wireless transmission and at the same time  i realized that it’s not feasible for the long-distance power transmission. But it can be used in the portable device charging. So, I focused my research on the portable device charging.

Wireless charging pad for mobile and laptops, wireless charger for artificial pacemakers, wireless charger for electric cars. From those all applications i have selected wireless charging pad for mobiles for the prototype development.

The wireless charging system consists of a transmitter which includes a power circuit and magnetic oscillator which generates a signal with high frequency. That signal feeds to a coil. Receiver section consists of a Receiver coil and rectifier circuit with voltage regulator. regulator maintains a constant Voltage output.

I discussed these all with my classmates and we formed a team, and our department gives permission to use the lab for testing. we designed an oscillator circuit and transmitter coil. we did some testing in order to check whether the power transfer can be possible through this arrangement. After the testing we realized that that circuit is not enough carry power for the mobile charger.

Around 1-2 months testing we found one circuit which can transfer the power for the mobile charger. at that time my dream was Indian made phone with our wireless charging technology. These all the things happened 2015.

Today we wireless charging is common and premium phone brands are providing wireless charging as optional feature.

All happens for the good reason. When a door is not open towards you, still gives an opportunity to knock other doors. If I quote Paulo Coelho words, it might be a conspiracy of nature.

Inertial quality of sine wave

For an Electrical engineer can’t avoid the sine wave because whatever they are studying which always connected to the sine wave.

For example, when we are studying about power generation, the generated electricity is sinusoidal.When we move to signal processing and analysis, all signals are represented as the sum of sine function (Fourier series).Then we get to communication systems, there sine is considered as fundamental signal!

Have you ever thought about why sine wave is a fundamental wave???

Some might know this reason, sine wave can be produce In lesser cost, but that is not the only reason, to sine wave considered as fundamental.

Sine wave has a unique quality compared to other forms of waves.

Before that, let me explain some basics of electrical circuit. For an electrical circuit, contains components like resistor, capacitor, and inductor. All electric circuits comprise these three major items. In an electric circuit Capacitor means, which will function as an integrator. And the Inductor means which will work as a differentiator.

Coming back to sine wave, when a sine wave passing through the capacitor, which will be integrated. IE a sine wave is passing through capacitor which will be converted as a cosine signal.in other words which will be changed as sine wave with with a 90 degree phase shift.If sine wave is passing through an inductive circuit which will be differentiated and  output is an inverted cosine signal. 

For a square wave when it passes through capacitor which will be converted as triangular wave .when we observe all the waves and behavior in electric circuits its loss its basic nature and changed to different form.but In both cases, sine wave keeps its sinusoidal nature. In my opinion This is the major reason for sine is considered as fundamental wave.

In our way of life, we might pass through up and downs. Sine teach us to never lose our qualities even we are going through the obstructions and struggles! 

Be like sine wave!

Always be like sine wave!

After my Btech. degree I did Specialization in automation technology and joined in automation company, from there I got exposure in certain process control projects like water treatment plant automation, crusher automation medium level substation automation, machine automation which were all for to reduce the Human efforts in the manufacturing process and improves the quality of the product. Those were all really excited project, and I had got a opportunity to involve in the gyro sensor manufacturing machine automation for t one of the ISRO lab...

Which has enterally different from systems that I had worked before. instead of controlling the machines here only accumulating the data's and give instructions to maintenance teams. I got surprised, even with a minimum number of technicians, they are effectively maintaining the system uptime as high (for communication network output is rated on terms of up times i.e. for tower needs to be functioned 24hrs).

Before talking about that system, I would like to brief about the mobile communication system, simply in mobile communication system consists of mobile towers and Fiber networks. For tower-to-tower communication the fiber network and microwave bands are using, nowadays towers are mostly connected with fiber network. Other connectivity is from tower to mobile phones, for that   radio bands are using. For this, system have different equipment's like RF antenna microwave antenna, EnodeB which is the heart of mobile communication system, routers, and utility system like gen-set, rectifiers and batteries. in order maintain the system at 100% uptime each Equipment having one dedicated engineer for the maintenance coordination Utility engineer for the power,Enodeb engineer for the Enodeb, Backhaul and IP engineer for the routers for one engineer for fiber maintenance. With these 5 engineers and 20 technicians along with the automated maintenance system they are controls operation of 900 mobile towers in the 2 districts.
From my point of view that automated system is the vein of of the operation team which were connects the field level technicians' engineers and higher-level managers.

The scope of the automated system is,

•Fault monitoring 

•Alarm generation  

 •Information about the fault module passes to corresponding technician and engineer

•Help to find the Root cause of fault 

•Spare Material movement Tracking 

•Spare management 

•Effective tracking of fault rectification.

In detail, once any of the equipment got faulty in the system then automated system will generate a trouble ticket (TT) and give an automated call and message to corresponding technician and engineer. That TT has to clear within four hours. After getting the message Technician needs to go to the tower location, which is also tracked using the software. after reaching the site technician check the fault and he has to inform the engineer whether any spare required for the fault rectification and engineer will book the material against that trouble ticket and mobilize the material from the local warehouse to fault occurred location. This has to complete within the time of four hour span otherwise first level escalation will go to the managerial level and if there is reason manager will extend the time to 8 hours.

Perception!

Mathematics is a must-study subject for our students in classes 1 to 10 in our system of education. The standard form of the dimensional equation we are studying during this period,

(a+b)^2=a2+b2+2*a*b,

Sinx !

Cosx !

Tanx !

Do we usually use them in our daily lives???

Yet, have you ever wondered why we are learning what? 

The need for the study of mathematics is very high in modern times when unscientific information, fake news, and truth travel faster.

Mathematics organizes our lives and prevents chaos.  Some of the qualities that maths nurtures are the power of reasoning, creativity, spatial understanding, critical thinking, problem-solving ability, and effective communication skills.

Maths is the cradle of all creation, without which the world cannot move an inch. Whether it's a cook or farmer, a carpenter or a mechanic, a shopkeeper, a doctor, an engineer, a scientist, a musician, or a magician, everyone requires mathematics in their everyday lives.  Even insects use maths for survival in their regular lives.

Snails create their shells, spiders design their nets, and bees prepare hexagonal combs. There are countless examples of mathematical patterns in the fabrics of nature. Math puzzles and riddles encourage and appeal to a cautious and open-minded attitude among young people, and help them develop clarity in their thinking. The emphasis should be on developing a simple concept in a child's maths from elementary classes itself.

Modern times are all about skill development and innovation. The more mathematically we are in our approach, the more successful we will be. Mathematics gives rationality to our thoughts. It's a tool to make our lives simpler and simpler.

The Commencement

Everybody has dreams… It could be about career ambitions, taking a treacherous solo trip, or enjoying a a lovely beach date.....

Some dreams are crazy, some romantic, and some about healing. Indeed I had dreams…later they were all just mine, but when she entered, it was all our dream together.

While I was a kid, my mom used to tell me stories from the Bible during our dinners. I will never forget her telling the myth of Jonah and the whale. As a child, I always visualized about that fish after hearing Jonah's story…

How vast could that fish be…???

Where can I see that fish...????

Are they still out there?

I assumed I'd someday see those gigantic fish..?

When I was growing up, I used to read Balarama every week. There was a a novel about a big white whale called Moby-Dick. I was rooted in my dreams of seeing whales after reading Moby-Dick. It was then that I realized whales cannot be seen in the sea. We have to go to the ocean for that to happen.

Then in 2015 after my college, I saw a film called In the Heart of the Sea. That movie was inspired by the novel Moby Dick. After watching that film, a desire to see whales again grew.

when I was too young, whales were like so big fish that can eat humans... but when I was in my tens they were those big fish that hunted for their oil. Some chapters in Moby Dick make me wish I could haunt whales. Whaling was a warrior's job when it came to that golden age. Whaling provided oil to light up their homes... prosper their nation. I felt like I was living in that era when I was reading that novel.

As I said from the beginning, that book strengthened my roots of dreaming about seeing whales. Growing up, I also became more clear about that dream. Now I know where I can find those big whales.

My plus two days were over, and I was already going through the entrance exam, preparation for engineering. My results arrived, I got a decent rank. The only confusion was with which branch I would choose.I had chosen to decide a general branch. My parents encouraged me to select colleges in my vicinity. There are three colleges within 10 km from my home. I am considering a mechanical branch from any of these colleges. At that time, mechanical was a highly demanding course. So, I didn't get that branch. I was allotted an Electrical Engineering branch in my college, which was closer to my home. I decided to join there. That's where my story as an electrical engineer began.

X+8=75

Self Motivation!

X+8=75

Most of the btech students (before KTU) knows this equation 😇and some of them have written this equation in answer sheet many times😄, instead of 8 it would have varied from 10 to 35. I didn’t write this equation in my answer sheet😎. But still, I do have a story to tell about this equation! 🙃

Every so often the most painful things🥺 that you have faced in your life past, would be the strength 💪🏼of your rest of the life or might be the path divertor in our life. I, too, have a story to tell like that!😁

Some might thinks now I do have 2 stories to tell😄😄, right?? 

But actually not🙂

Then why this much introductory !!just build-ups bro😁 😉ok let's us come to the topic…😎

 I got one supplementary in my seventh semester of btech😞. Reason was I was under in internals. Under means not in range of 30-35. I got only 8 marks out of 50, and I have to get 67 out of 100In order to pass that exam. In first attempt I got only 59😞. That subject was purely theory paper, how much you write you will get Maximum of 70+ and that's also depending upon the mood of evaluator during evaluation time 😕. 

Communication engineering!

FM, AM, sat lite communication, TV, radar digital communication

Oh see still I'm remembering those modules😌😌😌!!!

Even after the 8 years💪🏼!

That was the subject,

I've written 4 times Supplementary, into crack that magic digit 67. Every time I am writing that exam I nearly had got 55-60🥺.but those not were enough to pass that exam. At that time, I thought due to this paper I won’t get my btech degree. I worked hard, and I went to all churches ⛪️ prayer to pass that exam. Now I am thinking about that, those prayers 🙏🏼gave strength to survive the most stressful days. For attending that exam, I quit my job and taken full concentration on that exam. After 4th supplementary, I have passed that exam with a mark of 71/100💪🏼.

 For me, that supplementary exam was like a path changer, 😎and it’s given a right direction to career. ↗️After my btech results came, my parents were upset about my supplementary exam. Since I got admission in btech with very decent entrance rank in 6000 ranges they didn't expect something like from me, even I don’t expect this type of tragedy would happen to me .and that was the only paper I got supplementary. And they were wanted to hide those from my relatives and neighbors, for that, they gave me option to join a short time course. Then, I joined PG-diploma course in automation and that decision changed my life. In last 8 years I am working in field of automation.I got great opportunities to work with organizations like reliance industries, if I turn back and thinks, those supplementary exam was the real path changer of mine.

Whenever I felt something lost or delaying in my life simply look on this Mark sheet and would tells me,Anoop,you have survived this, and you have the strength to move on from everything. 

Even if it has delay… 

You will definitely get those you have deserves at the right time.

For anyone passing through this same situation, the only thing I have to say is

  

Keep trying!

Work hard!

Keep praying!

Everything will be alright.☺️
