Salam Alekum and hello to eVeRy BoDy…..
4th of December is my first day of Petrosains UTP Science Communication Program. It was a nice and an interesting day. I enjoyed the activities and the briefings involved. I got learned many things out of them. It’s true that I get bored listening to briefings that takes long and today I could stand them except last briefing and last session for the day which was the Safety & Security TAlk. I was feeling sleepy as others were. It was even longer than it is because of tiredness.
The most activity I enjoyed was ice breaking session where my group won the first place for the structure we built. NOW, I can say I am proud of my group "E_OIL" group. Thanks to all my group members for corporation and CONGRATULATION the price. I also want to say Congratulation to all friends for passing the challenge and winning the time that they enjoyed and learned from as well as the friends.
Then to Col Talk with MR. JAMMY for the session he gave us. It was beneficial and fun. It was really good experience to gain.
Last but not least, I would like to thank all those work for this project and I really hope all go on successfully and as planned.
To all friends ……………..HaVe FUUUUUUUUUUUUUUUUUUUUUUUn and enjoy urself.
ur sister,
SaMeHa

Overall a very positive post! And you are so right about the safety briefing. Even thinking about it makes me sleepy. lol
Dear Sameha,
I wanted to let you, Safwan and Akesoh know that I had an interesting e-mail exchange today with Tajuddeen about how the "atuo tap" works in the toilets at Petrosains. Basically, it uses photoelectric sensors which uses an infrared transmitter and a receiver side-by-side to detect the presence/absence of target objects. In the particular type used in the auto-tap, the transmitter (as in TV Remote) emits infrared light. When there is the presence of any object (within designed or
tuned range), the emitted infra red light will be detected by the infrared-receiver
(similar to TV set receiver) which then turns on an electric switch, which in
turn activates (opens) an electrically controlled valve, which opens the tap.
In other words, the object, usually your hand, reflects infrared from the transmitter. A flash of camera or even fire alarm in the toilet also emits infrared light (among other wavelengths), so the receiver is not "intelligent" enough to differentiate this from the infrared of Photoelectric transmitter. (transmitter and emitter are the same thing)
You may have noticed that it also has a timer (which can adjusted by our technicians), which determines how long the valve remains open after the electronic switch closes (absence
of an object). This is to ensure a smooth opening and closing of the valve, and
normally will be set to about a 2-4 seconds.
I hope this is some of the information that you were looking for. Please let me know if you have any questions and keep pursuing those good questions in the project that you present next week, Whatever you do is up to you!
Cheers, Jamie
Dear Sameha,
Thank you for your comment on my blog. I wish you all the best on your presentation today and I encourage you to send me your question when you are ready to. Happy New Year from Pittsburgh, Pennsylvania, USA.
