What Engineers could learn from the movie "Titanic"

A couple of days ago, I went to see Titanic 3D. This is my second, or maybe third time seeing the movie since 1997/1998 (it’s true, I swear! I know some of you saw it 10 times back then, don’t lie to me ;P). Back then when I was a teenage girl, Titanic did not left any impact on me from the engineering point of view, all I saw was the tormenting love story between star-crossed young lovers, Jack and Rose. Of course, I was like any other teenage girl back then, all doe-eyed for Leonardo DiCaprio.

Alright, this post is not actually about all the gushy-mushy gooey dooey loveyy storeyyy or how cute Leo is, but rather it is about the engineering lessons we could all learn from Titanic (3D or 2D, likewise).

Virtual Sky - Working under an Open Sky

Do you feel happy working under a clear blue sky as opposed to working in a stark office environment? Are your office employees shuffling around like zombies, or nodding off to a sleepy start in the conference room during meetings? Then fear not, for Virtual Sky will improve your employees productivity by providing them a chance to work under the infinite horizon of a clear blue sky! Or so that is how it goes...

This is how I work ever day (not the Party Rock way...)

Reading a recent news article from the technology section, I went in search for more information regarding this new innovation. Developed by Stuttgard-based Fraunhofer Institute for Industrial Engineering, or IAO in short (Institut fur Arbeitswirtschaft und Organisation) and exhibited in CeBIT Trade Fair in Hannover in March 6-12, 2012 was a matrix of ceiling lighting panels simulating clouds moving across a clear sky.

What I "think" do vs. What I "really" do

"Hello world"

That phrase is one of the memorable words I learned to program in Computer Programming class. And those exact words is what I would like to greet you all with in my first post here as a guest blogger. I am very much excited to share some of my thoughts and experiences here and I do hope we all could exchange ideas along the way.

In the past few weeks, we've seen these meme about "What others think I do vs What I actually do..." one too many times. Most of these reproductions are really funny, quite to an extent that it is a chilling truth that we hate to admit.

(My notes today will talk about electronic engineering in general, but maybe it could relate to other engineering fields.)

IP rating - IP5KX vs IP6KX

In the previous article, the first numeral code for an IP rating is mentioned as the protection level of a product against intrusion of foreign object, with IP5KX and IP6KX being the highest level. This article serves to elaborate on the latter requirements and how they differ from each other.

IP rating - Dustproof

Instead of claiming a product is 'dustproof', a better way of stating it is 'protection against foreign object intrusion', as is mentioned within IEC60529. There is a reason to it, as a product is not only in danger of being harmed by intrusion of dust or sand. One look at the grills of a table fan and it is not difficult to understand that its purpose is to prevent accidental and intentional (in the case of innocent infants) access to the dangerous rotating blades of the product. 

IP rating - Protection against Ingress

Ever use products that failed because of water seeping into the interior? Or maybe sand jamming the moving parts? It is quite usual for products to be designed to be 'waterproof' or 'dustproof', but as an engineer, how do you know if they really are as they claimed, or what to look out for to know how 'waterproof' it is?

Engineered items are usually labeled as sealed against dust or water through a system known as IP rating. The IP code labeled on products and claimed in technical datasheet will provide users and buyers the degree of protection provided by mechanical casings and enclosures of electrical equipment against the following:

• protection against foreign objects (e.g. sand and dust)
• protection against effects due to ingress of water
• protection against access (accidental or intentional) by persons to hazardous parts inside the enclosure

Uni-signal - Traffic Light for Color Blind

If you think that there would not be any new designs that will surprise you the way i-whatever did, think again. Especially when you were rushing the red light. Surfing across the web in a lazy evening brought to my attention the design of Uni-signal, a traffic light with a slight variation from the norm.
