Robot-like Vision

noreply@blogger.com (shane) — Sat, 01 Mar 2008 11:27:00 +0000

"Looking through a completed lens, you would see what the display is generating superimposed on the world outside," said Babak Parviz, a assistant professor of electrical engineering, University of Washington in Seattle. This simply means that you would possibly see anything that is projected on to the display of your contact lenses along with the natural objects that we see on the world outside..such as in science fictions. Surprising..isnt it?

Well…UW engineers have already developed a prototype of this amazing device and have already tested on rabbits for any adverse-effects. The results were truly encouraging —no adverse effects were produced by the rabbits after testing for up to 20 minutes.

"Lenses were already test on rabbits"
- A rabbit wearing a lens

The lens comprises of an electric circuit as well as red light-emitting diodes for a display. As this still a prototype the display does not light up yet. “A full-fledged display won't be available for a while, but a version that has a basic display with just a few pixels could be operational ‘fairly quickly’ ” according to Parviz.

In order to develop a safer devise with no adverse effects for eyes, engineers have used flexible organic materials to build up its electronic circuits. A method called microfabrication technique known as self-assembly has been used to set its tiny electronic components in the correct positions within the circuit. Designers of the devise say that these components will not affect the lens-wearers vision as they entirely occupy the positions outside the transparent region of the eye.

Still, researchers are continuously working on the devise in order to place further improvements to enable wireless communication, and to power up the lens using radio-frequency power and solar cells.

Thanx.!

Brain Reader..?

noreply@blogger.com (shane) — Sat, 01 Mar 2008 10:28:00 +0000

A group of cognitive neuroscientists and computer scientists in the Carnegie Mellon University have successfully developed a technique to tell what other people are thinking, by observing their brain activity.

When a person thinks of some particular object, thoughts and perceptions are generated in various positions of the brain producing a particular pattern specific for that object. Different objects cause different patterns. By combining medical imaging and machine learning methods, scientists have been able to develop a novel algorithm—a set of well defined instructions to classifying them according to their corresponding objects. As a result, by analyzing those patterns, one can exactly tell what others were thinking about in a particular moment.

In addition, when this algorithm is trained from datasets obtained from a particular person, it could correctly classify unknown datasets obtained from a different person showing that there are similarities between brain activities of two different persons. "This part of the study establishes, as never before, that there is a commonality in how different people’s brains represent the same object," says Mitchell, head of the Machine Learning Department in Carnegie Mellon's School of Computer Science.

Finally researchers are hoping to develop this new technique further in order to use this as a valuable tool for studies and research in neurological disorders, such as autism.

Thanx.!

Find out your ' IP address '

noreply@blogger.com (shane) — Sat, 01 Mar 2008 05:47:00 +0000

You know that every network connection has its own IP address. But, do you know how to find that address? NO..? well, just follow the simple instructions below..

1) Go to Start and then go to Run

2) Type ' cmd '

3) In the opening command prompt, type ' ipconfig ' - This result will provide a little bit of details of the connection, including the IP address.

Is the above information regarding the connection insufficient? If so, just type ' ipconfig/all ' in the command prompt and it will provide you with much more information.

Try it..

Microprocessors or Microcontrollers... We are alike.... but not the same.

noreply@blogger.com (shane) — Wed, 20 Feb 2008 07:49:00 +0000

PIC10F is one of the world's smallest microcontrollers

Generally microprocessors and microcontrollers differ in a number of ways, mainly in its functionality. Because microcontrollers can control a number of processes and devices independently whereas microprocessors need integration of additional peripherals with it.

This is the basic structure of a microprocessor. In order to carryout the functions, this needs to be integrated with other hardware components.

Microprocessors are regarded as the heart of the system/computer. On order to act in such a way it needs RAM, ROM, registers, I/O devices; as said before it needs integration of other hardware. But in a microcontroller chip, it’s a whole different story. They have all the above components embedded inside; more generally it is defined as a device that includes a memory, & input / output devices and also a microprocessor, lined on a single chip. In modern microcontrollers, they contain Serial I/O, Timers, and Analogue to Digital Converters. Actually it’s more like a little computer inside a little chip.

This is a microcontroller chip; identify the microprocesser, integrated onto the microcontrolle surface.

In simple terms a microprocessor is actually a ‘processor’. It is the ‘central processing unit’ of the computer as everyone knows. But a microcontroller is actually a ‘controller’ of a system; When we enter a certain user-defined task or a program into the microcontroller, it simply loads it into the memory, and runs/executes it.

In addition, microcontrollers are cheaper

Microprocessors -> General Purpose Machine
Microcontrollers -> Embedded Systems

Microcontrollers are mainly used in embedded Systems.

So.. these are the main differences between microcontrollers and microprocessors.

Thanx.!

This is how NOKIA phones are made..

noreply@blogger.com (shane) — Mon, 18 Feb 2008 17:45:00 +0000

A factory where nokia phones are made. Currently there are 9 such factories around the world.
Well...Find out how your NOKIA phone is developed

Step 1 - All the electronic components in a phone, like memory chips, microprocessors, resistors, capacitors etc.. are produced by outside suppliers in mass scale. Then those are delivered to the factory, attached on reels of tape protected in circular plastic cases.

.

Step 2 - A circuit board which has a latticework of basic circuits, is inserted into a “paste printing machine”, which applies a patterned layer of solder paste on the surface—printing of circuit board.

Step 3 - The reels of tape containing electronic components are fed in to automated "pick-and-place machines” where those components are removed from the reel and pasted on correct places in the printed circuit board.

Step 4 - Printed circuit boards travel through a series of pick-and-place machines and after reaching the end, printed boards are inserted into an oven where they are melted causing the added components to attach firmly to the circuit board.

.
.

Step 5 - Circuit boards are loaded onto ‘tracks’ automatically. There, first quality test takes place and then basic software is installed into programmable components.

.
.

Step 6 - Circuit board are taken off from the tracks, by a specially designed robotic arm and are placed in a bay where low-level settings such as power settings are configured in electronic components. After this, a series of electronic tests are carried out in order to ensure, whether the circuit board is perfect, all the parts work, and that they have been correctly installed.

.
.

Step 7 - From this point forward, development is mainly performed using human hands/manually. Mainly, removal of some components, like expensive and fragile liquid-crystal display screens, from the reel and pasting them on a circuit board is done manually.

This picture shows a worker adding a digital camera module/component, which has been removed from a reel using tweezers, onto an assembled, tested, printed circuit board.

.
.

Step 8 - Completed circuit boards are sandwiched between front and back structural frames and then phone’s outer cover is applied.

.
.

Step 9 - Here, turning the phone into a usable model is done. This includes installation of set of menus, features and setting up of the start-up screen for each different phone type.

In addition, a serial number called ‘IMEI code’ which uniquely identifies the phone given.
At the end of this stage, the phone and installed software undergo a battery of diagnostic tests.

.
.

Step 10 - All the phones undergo a final inspection by human eye. Phones that pass the inspection/test are de-ionized to remove any electrical charge and dust from the surface.

.
.

Step 11 - Phones are packed into retail boxes by hand, with appropriate documentation and accessories. Then these are logged into a tracking system using a bar-code reader.

.
.

Step 12 - Finally brand-new phones are packed into boxes.

.
.

Step 13 - Containers carrying boxes of phones are transported and distributed throughout the world.

How to make a file to AUTORUN when the CD is inserted

noreply@blogger.com (shane) — Sun, 17 Feb 2008 18:32:00 +0000

This can be done easily by including an .inf file along with your interested folders when burning the CD. You can use the Notepad for this.

First open up the Notepad. Then type the following,

[autorun]
OPEN = filename.exe

‘filename’ is the name of the file that you want to autorun. But remember this file should be an .exe (executable) file or in other words, this should be an application file. If the file that needs to autorun is located inside another folder, you should give the correct path of the file.
ex:- OPEN = foldername / filename.exe

Then save the notepad ; name it as AUTORUN.inf

When burning the CD include the above file(AUTORUN.inf) along with the other files or/and folders.

Check whether your Antivirus works well...using a Fake Virus

noreply@blogger.com (shane) — Sun, 17 Feb 2008 11:07:00 +0000

You can check whether your anti-virus software works fine by using a ‘fake virus’. This virus is not a real one. Therefore it cannot harm your computer. This testing is called eicar test.

First open up your Notepad or any text editor. Then carefully type the code below; this should be in single line. ok.

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

Then save the file. The file name should be “eicar.com”. Give the file type as “All Files”.

Result: If the existing anti-virus program in your computer works correctly and accordingly to the standards, it should trigger a warning alert at the very first moment when the fake virus is saved..!

(This test can be used only on the virus guards produced under the regulations of “European Institute of Computer Antivirus Research (EICAR)”. Most of the virus guards are produced under this regulation)
