[Journal 6] - Electronic System in Industry

Assalamualaikum w.b.t.,


Moshi-moshi, Genki ni shite imashita ka ? I back to write sixth journal for my Electronic System Engineering course under Malaysia - Japan International Institute of Technology (MJIIT). This journal basically about electronic system in industry. Talk was given by Mr Vivek Panicker, Executive Director of Titan Thermal Solutions on 20th November 2012.

Talk was divided into four sub-topic which are:
-Overview of Electronic Systems.
-Role of Electronics in Industry.
-Overview of Imaging Industry.
-Electronics within Thermal Imaging Industry.

Overview of Electronic Systems

-Definition of electronics
   "electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies” – Wikipedia

Electronic systems are a group of electronic circuits designed for a specific purpose.
Fundamental to our daily life.
Have played a key role in advancement of technology.
Replaced previous systems and are more integrated into current society.
Will be a mainstay in future development.

Progression of electronic systems:
   Large – Small – Miniature
   Simple – Complex Architectures
   Analog – Digital

Role of Electronics In Industry

 Vital to current information and technology era
 Penetrated seamlessly through various industries
 A catalyst to enhanced production and productivity within the industry
 Most Industries today are heavily dependent on Electronics

Conventional classified into:-
        Consumer
        Industrial
        Defence
        Communications
        Information Processing Systems

Modern day medical, imaging, transportation and power utilities segments are classified individual
However current day electronics often blur the lines of classification

Consumer Electronics
  Oldest segment of electronics with the advent of radio receivers
  Geared towards the push of consumer products
  E.g. Microwave, Discman, Nintendo

Industrial Electronics
   Oriented towards manufacturing products required by modern industry
   Process controlled equipment, robotic equipment for test and measurement
   E.g. Network Analyzers , Robotic Arms, Electronic Control Systems

Defence
  Strategic , creates spin-off electronics for other segments
  Pushed the growth of Material Science technology
  Frontier of modern electronics

Communications
  Current rapid growing field
  Benefited from semiconductor lasers, optical fibre technology, digital techniques

Information
  Processing Systems Development of Integrated Circuits (IC’s), Application Specific Integrated Circuits
  (ASIC) designs,
   Very Large Scale Integration (VLSI) circuits; micro-controllers, microprocessors, memory modules, Field- Programmable Gate Arrays(FPGA)

Medical
  Creation of medical testing and monitoring equipment
  E.g. ECG machine, NMK scanner

Imaging
   Developing and providing the platform for new techniques
   Create a modern infrastructure to provide detail imaging

Electronics plays two crucial parts in industry, as a platform for development or design of new systems and as a means to increase productivity of current systems.

Overview of Imaging Industry

Imaging is the representation of an object’s outward form :
 +Chemical imaging, the simultaneous measurement of spectra and pictures
 +Digital imaging, creating digital images, generally by scanning or through digital photography
 +Geophysical imaging
 +Medical imaging, creating images of the human body or parts of it, to diagnose or examine disease
 +Molecular imaging
 +Optical imaging
 +Radar imaging, or imaging radar, for obtaining an image of an object, not just its location and speed
 +Thermography, thermal imaging

Advent of electronics, moved imaging into new heights.
Development of new methodologies.
Moved imaging technology into new wavelength spectrums for commercial usage.


Basic Concepts & Terms
     Pixels & Resolution
            A digital Image is formed by pixels.
            Smallest piece of information in an image.
            Often represented using dots, squares, or rectangles.
            More pixels in an image, the sharper and clearer the image is.
     Video & Frames
            A digital stream of video is made of a group of pictures (Frames) captured across a period of time.
            More frames per second, the lesser the jitter in the video.



     NTSC & PAL
             Human eye requires a minimum 25 frames a second.
             PAL TV standard :-
                 25 frames per second(25 hertz or 50 hertz half frame).
                 Resolution of 320 by 720.
                 Asia, Europe, South America and East Africa .
             NTSC TV standard:-
                 30 frames per second(30 hertz or 60 hertz half frame).
                 Resolution of 480 by 720.
                 North America and Japan.

Imaging Industry requires processing huge quantities of data in a short span
Electronics eases these complexities
Making imaging technology affordable

Electronics within Thermal Imaging Industry

Thermal Imaging originally a spin-off defence electronics
Makes use of wavelengths in 7-14µm to form an image
Sensors make use of focal plane arrays and are commonly Indium Gallium Arsenide (InGaAs)
Often referred to as a “dirty imaging system” compared to CCD and CMOS architectures
A lot of pre and post processing of data is required
Thermal requires Non-Uniformity Calibration (NUC) on data stream.
Data varies in state and space.
Enables implementation of intensive algorithms such as Kalman filters, Edge Detection, Neural Network Modeling.
Equations are expanded into models that are described in electronics
Electronic processing data allows thermal imaging to be used in various other industries.
Electronics and the advancement of technology has huge impact on Thermal Industry
Growth from Solid State Devices – Material Science Development – Digital Imaging Methodologies

 At the end of session, Dr Kamal told us that we going to visit Canon Opto Malaysia in Shah Alam next week.
