Canon makes 250 megapixel sensor

Canon logoJapanese giant Canon said its engineers have put together a 250 million pixel censor that’s smaller than a 35mm full frame censor.

The sensor is capable of seeing letters on the side of an aeroplane flying at 18 kilometres distance.

The censors pixel count is 19,580 x 12,700 pixels and has a read out speed of 1.25 billion pixels per second and can capture ultra high pixel video at five frames a second.

Videos taken using a camera with the sensor reached a level of resolution 125 times that of full HD video.

But you might not be able to buy a camera for a little while because the sensor is aimed at surveillance and crime prevention tools, high resolution measuring instruments, and industrial equipment.

Institute of Microelectronics, University of Illinois team up for nanowire sensors

The Institute of Microelectronics in Singapore has teamed up with the University of Illinois to research and develop nanowire sensors in efforts to commercialise the technology.

The deal will see the Institute and University working closely together on researching how to systematically optimise nanowire sensor design and develop techniques for batch fabrication. The ultimate aim is to improve the stability of nanosenors and come up with ways to reproduce the technology in a commercially viable way.

Nanowire sensors could be used to provide quick, low-cost and high-throughput analysis of biological processes, thanks to their highly sensitive ability to detect biomolecules, but the lack of knowledge and optimisation of their design is a key blocking point that prevents widespread use. 

There’s still a lot to learn about the technology, which the collaborative duo hope to figure out over the next few years, using the University’s designs and the Institute’s Bioelectronics Programme, silicon fab and research staff.

The team will begin fabrication of top-down silicon-based nanowire field-effect transistor sensors and nanoplate arrays which were designed by the University of Illinois. They will then be tested at detecting cancer protein biomarkers, which could eventually lead to them being used in point-of-care diagnostics systems.

Sony 3D TV: Big Brother is watching you

Behind Winston’s back the voice from the telescreen was still babbling away about pig-iron and the overfulfilment of the Ninth Three-Year Plan. The telescreen received and transmitted simultaneously. Any sound that Winston made, above the level of a very low whisper, would be picked up by it, moreover, so long as he remained within the field of vision which the metal plaque commanded, he could be seen as well as heard. There was of course no way of knowing whether you were being watched at any given moment. 1984, George Orwell

Here’s a funny one from the Wall Street Journal.

The newspaper said that when Sony launches its new 3D television around the middle of this year, it will sense when a kid gets closer than a metre to the screen and if it does so will black out the screen and show a message telling your child to take a hike.

It’s assuming a child can read a message, obviously.

The Journal said that the TV will include a sensor and can tell whether the individual getting close to the screen is a child or an adult.

George OrwellIf it’s an adult, the screen won’t display the message, although surely it should say something like “get your eyes tested, old timer”.

The sensor can also do spooky things like tell how many people are watching the screen. If there’s only one of you, but you’re not directly in front of the set, it will apparently swivel the sound in your direction.

But surely Sony could take this a lot further, and include sensors to monitor your blood pressure and heart rate? If you get too excited, perhaps it could tell you to go take a Prozac or get your defibrillator ready.

And if you’re doing something naughty in front of the 3D TV, perhaps it could also tell you off if you’re under 18 or over 60. And take snaps of you which it could send “home”.
