Bionic eyes are just around the corner..
One of the greatest things about reading science journals over the years is watching stuff evolve into real applications..I've been following this development for about 5 years now; BBC NEWS Elastic electronics see better By Jennifer Carpenter Science reporter, BBC News A new camera designed with a curved detection surface allows imaging devices to see as animals do. The camera, inspired by the human eye, relies on the ability to construct silicon electronics on a stretchable membrane. In the future, these electronic membranes could be wrapped around human organs to act as health monitoring devices, say US-based developers. The new technology is described in a paper in the journal Nature. Photosensitive displays - like the ones used in digital cameras - are made up of thousands of pixels and are usually formed on a flat, rigid, semiconductor wafer, explained Dr John Rogers from the University of Illinois at Urbana-Champaign, US, who led the team of researchers. "No animal's eyes are like that; the retina is curved," Dr Rogers said. "This curvature allows animals to see the world without distortion - unlike the images produced from cameras, which lose focus at the periphery." Hoping to improve digital imaging, the Illinois-based researcher and his team, joined up with a group of mechanical engineers from Northwestern University, to make a camera shaped more like an eye. The challenge was to import the thin, brittle wafer-based camera technology to a curved surface. The result was a 2cm-wide camera with a single, simple lens and a concave light detection system. Wafer-thin The team approached the initial problem by dicing up the surface of the silicone wafer into "chiplets" - tiny pieces of silicone that detect incoming light. Then, the world's smallest cables, only one micron thick - the equivalent of 1/100 of the thickness of a human hair - provided the electrical connections between the adjacent chiplets to make a circuit. Dr Rogers explained that if you squeeze the circuit, the cables allow the chiplets to move relative to each other. Next, the team developed a curved elastic membrane. Dr Rogers said that they had grabbed the edges of the membrane, pulling it in all directions, until taut and flat. Then the researchers dropped the mesh-like circuit of "photoreceptors" onto its surface. "We released the membrane, let it snap back and saw that it puts all the photosensitive chips into compression," Dr Rogers said. "The ribbons pop-up, forming bridges between the chiplets, and so maintain the electrical connections." Flexible imaging He added: "The interconnected mesh allows you to stretch, deform and reshape the circuit of photoreceptors [giving you an undistorted image]." This is the first time anyone has moved electronics off rigid semiconductor wafers on to a fully flexible surface. The applications for this "flexible, stretchable" technology are vast, Dr Rogers told BBC News. The photoreceptors could be swapped for any other type of receptor, and the whole circuit integrated into the human body for health monitoring. "Look at the human body; there is nothing rigid about it," says Dr Rogers. His team is already developing circuits that contain electrodes, housed in the same membrane, to wrap around portions of the brain in people suffering from epilepsy, to act as an early warning system for seizure. This technology could also be used in the heart to emit tiny electrical signals, acting as a very advanced pacemaker.
 
 
   
 

Run From Refurbished?
Ok, so I'm wondering if I can trust a refurbished electronic item, namely an ipod.  20 GB, amazing price...I just don't know if I should trust a refurbished item.


 
 
 

   
Waz up every body!!!!!!!!!

SmileyThe doll and the rose

I was walking around in a store. I saw a cashier hand this little boy 
his money back saying "I'm sorry,  but you don't have enough money to buy This 
doll." 
Then the little boy turned to the old woman next to  him: ''Granny, are 
you sure I don't have enough money?" The old lady replied: "You know that you 
don't have enough money to buy this doll, my dear." 
 
Then she asked him to stay there for 5 minutes while she went to look 
around. She left quickly. 
The little boy was still holding the doll in his hand.  Finally, I walked toward 
him and I asked him who he wished to give this doll to.  "It's the doll 
that my sister loved most and wanted so much for this Christmas. She was so  
sure that Santa Claus would bring it to her." 
 
I replied to him that maybe Santa Claus will bring it to her after all, 
and not to worry. 
But he replied to me sadly. "No, Santa Claus can't bring it to her  
where she is now. I have to give the doll to my mommy so that she can give it to my 
sister when she goes there." 
 
His eyes were so sad while saying this. "My sister has gone to be with 
God. 
Daddy says that Mommy is going to see God very soon too, so I thought 
that she could take the doll with her to give it to my sister." 
 
My heart nearly stopped. The little boy looked up at me and said: "I 
told Daddy to tell Mommy not to go yet. I need her to wait until I come back from 
the mall." Then he showed me a very nice photo of him where he was  
laughing. 
He then told me "I want mommy to take my picture with her so she won't forget me." 
 
"I love my Mommy and I wish she doesn't have to leave me, but daddy  
says that she has to go to be with my little sister." 
Then he looked again at the doll with sad eyes, very quietly. 
I quickly reached for my wallet and said to the boy. "What if we  
checked again, just in case you do have enough money?"  "OK" he said "I hope that I have enough." I added some of my money to his without him seeing and we 
started to count it. There was enough for the doll and even some spare money. 
 
The little boy said: "Thank you God for giving me enough money!" Then  
he looked at me and added "I asked yesterday before I slept for God to make sure I have enough money to buy this doll so that mommy can give it to my sister. He heard me!" 
 
"I also wanted to have enough money to buy a white rose for my mommy, but I didn't dare to ask God for too much. But He gave me enough to buy the Doll and a White Rose."  "My Mommy loves White Roses." 
 
A few minutes later, the old lady came again and I left with my basket. 
I finished my shopping in a totally different state from when I started.  
I couldn't get the little boy out of my mind.

 

Then I remembered a local newspaper article two days ago, which 
mentioned of a drunk man in a truck, who hit a car, where there was one young lady and 
a little Girl. 
 
The little girl died right away, and the Mother was left in a critical 
state. The family had to decide whether to pull the plug on the Life-assisting 
machine, because the young lady would not be able to recover from the coma. Was 
this the family of the little boy? 
 
Two days after this encounter with the little boy, I read in the 
newspaper that the young lady had passed away. I couldn't stop myself as I bought a bunch of white roses and I went to the funeral home where the body of the young 
woman was there for people to view and make last wishes before  the burial. She was there, in her coffin, holding a beautiful white rose in her hand with the photo of the little boy and the doll placed over her chest. 
 
I left the place, teary-eyed, feeling that my life had been changed forever.. 
The love that this little boy had for his mother and his sister is still, to this day, hard to imagine. And in a fraction of a second, a drunk driver had taken all this away from him. 
 

"With hurricanes, tornados, fires out of control, mud slides, flooding, severe thunderstorms 
tearing up the country from one end to another, and with the threat of bird flu and terrorist attacks. "Are we sure this is a good time to take God out of the Pledge of Allegiance?" 
 
For those that prefer to think that God is not watching over us....go ahead and delete this. For the rest of us.....pass this on.
