Avembsys: Day 2

First I like to apologize for being ignorant about many of the facts and like to thank for pointing it out.
Well.. today my day went on as usual with classes in the morning first half and labs in the latter half followed by our second session in the afternoon.
The class started by around 3 and for our surprise, we never expected our teachers to actually attend the session and sit with us! The class started with the basic exchange of information on our blogs that is when the second surprise hit us because we never expected our blogs to be read that thoroughly and the mistakes to be pointed out so well!
After informing everyone about the errors, the class moved on to the day's theme "almost right is 100% wrong".
We were shown the importance of quality control and reliability and its importance in avionics industry and how it plays a major part in aerospace. After which the basics of embedded systems were discussed and a video was shown in which we were asked to identify different embedded systems that came up it. I was able to identify 4 systems although Omer's vision was far better than mine as he was able to identify 7. We then moved on to the different missiles that are used both on a plane and off the plane and although I knew about the heat seeker missiles, the working of LASER guided systems were relatively new to me and it was intriguing. I got to know how the counter measures worked for its avoidance.
We then discussed about the basics of internet and about its origin and the cause of its existence and the we moved on to the types of systems and then came up to the embedded systems again and discussed the different levels involved in creating and deployment of the embedded systems using ppt presentation.
After this we talked about the real time systems and the different types in real time systems namely hard Real time and Soft Real time, although I did not understand the difference that clearly.
After that we discussed about the rts applications in defence namely for cruise missiles, the different systems that are present in the cruise missiles and also how it is able to hit the target with such great accuracy. I am actually curious as to how the IGS(Inertial guidance system) works as it said that it roughly tells the position of the missile by measuring its acceleration!
After this a handbook was handed over to us which showed the different modules that we would be exploring in the due course of time and also the dress code was told to us, but i didnt get why is it put up only for the guys of the class, cause in an industry if a gal is working, then even she would be coming under its norms and thus its dress code as well!. Anyways.......
We then watched few more videos of different aircrafts landings prior to which we were  shown a slide and was told to guess what the flight was doing, although my bets was on TOGA, it turned out to be a landing sequence! he then explained about the different types of winds that exists during landing and videos were shown on how the cross winds are compensated by changing the angle of descent. Well the video was rightly named ie scary landings my friend beside me was certainly getting second thoughts about travelling in the plane next time.. lol.
We later saw the complications that the US Airways 1549 faced due to which it had to land in the Hudson river, and I have to say that it definitely was a brilliant landing as even  if there was some angle variations, it would have led to loss of lot of lives. We then saw 2 videos on the mid air collisions, the one without TCAS system and another with TCAS system. I was actually more curious with the collision that took place with the TCAS system as what my thoughts is that, if two planes, carrying TCAS systems does not communicate with each other, and if both the systems order the pilot to descend (or ascend), it would also result in a collision!. I still need to do some googling on this, and I am pretty sure that I will be able to find it out, if not I'll raise this in the next session.
We were also shown the different flight instruments used to show the orientation and behavior of the plane and also we are yet to discuss on cloud bursting in the next session, so looking forward to it.

TILL NEXT TIME
GOOD NIGHT :)

avembsys: the first session

today we attended the first session of avembsys.. the feel was pretty good.. knowing that we would be implementing something with not just myself as before.. but with others as well.. the  session started with giving intro of all and what they expected from avembsys.. the interaction was surprisingly better than anything that i had expected with the guide taking each person's views and telling what he feels about it and what they can do to actually follow them. We then had a very interesting session where people used to give their ideas that they had in mind and the rest of the class would comment on it. In this i liked asad's comment very much on many of the ideas including the survivor detector using capacitance effect. that was the moment that i had most fun through out the day :).
I also presented mine and manoj's idea on body voltage and the response that i got was something unexpected. the guide actually heard me and suggested what to do from there (which usually tend to get ignored ) and now.. after coming home i tried implementing it again with a certain enhancement and the output is pretty remarkable and i am hoping that we will be able to get something out of this experiment :). We'll probably be verifying it again tomoro and hoping for a positive result.
All in all.. i liked the way that the class went and I didnt even realize how the time passed from 2 to 5!. and I am wishing that the rest of the sessions also goes smoothly and interactively as it did today.

TILL TOMORROW
CHEERS :)
