Time showing bed sheets a reality?

November 20th, 2009 by Thomson | No Comments | Filed in Coreelectronics

Think of knowing the time by just moving your hands over your bed sheet at night. The fact that you can know the time even without opening your eyes makes you feel great about this new concept? Hey, this is not just a dream. Wake up, its goanna be a reality! This is what time showing bed sheets talk about.

There are many different sources from which the “PRECIOUS” time could be known. Watches are the traditional devices that we commonly use to be aware of the minutes and seconds. Clocks hanging on the walls remind us about our duties. At office our PC’s and Laptops tell us about the deadlines, important meetings and the party tonight! The digital and analogue clock utilities in our mobile phones help us to be on time. Mobile phones are increasingly used as a time showing device, in such a way that watches are getting replaced!

How it works?

The Melted Clock is a haptic, touch sensitive alarm clock, with integrated speakers and controls all embedded into your sheet. Sounds a bit complicated, but parts of this are certainly possible today. There are three control icons on the sheet, as well as others on the side of the sheet. You can tell the time easily by using your hands or your eyes.

This clock uses silicone and electroactive polymer, which is used in artificial muscles, to work. The slat will expand and lift up the silicone. This means that the numbers and the clock are quite soft and won’t really bother you too much in bed.

Human Brain Simulator

November 20th, 2009 by Thomson | No Comments | Filed in Coreelectronics

Scientists and engineers at IBM’s Almaden Research Center announced today at the Supercomputing Conference in Portland, that they have created the largest brain simulation to date on a supercomputer. The number of neurons and synapses in the simulation exceed those in a cat’s brain; previous simulations have reached only the level of mouse and rat brains. Experts predict that the simulation will have profound effects in two arenas: It will lead to a better understanding of how the brain’s architecture leads to cognition, and it should inspire the design of electronics that mimic the brain’s as-yet-unmatched ability to do complex computation and learn using a small volume of hardware that consumes little power.

The cortical simulator, called C2, integrates research from the fields of computation, computer memory, communication, and neuroscience to re-create 1 billion neurons connected by 10 trillion individual synapses. C2 runs on “Dawn,” a BlueGene/P supercomputer at Lawrence Livermore National Laboratory, in Livermore, Calif.

The IBM research shows that a model of the human brain—which has 20 billion neurons connected by about 200 trillion synapses—could be reached by 2019, given enough processing power. But Johns Hopkins University electrical and computer engineering professor Andreas Andreou says the C2 simulator underscores an undeniable fact—to better understand the brain, we’re going to need a better computer.

A major problem is power consumption. Dawn is one of the most powerful and power-efficient supercomputers in the world, but it takes 500 seconds for it to simulate 5 seconds of brain activity, and it consumes 1.4 MW. Extrapolating from today’s technology trends, IBM projects that the 2019 human-scale simulation, running in real time, would require a dedicated nuclear power plant.

IBM is also working separately on nanomaterials that could enable the construction of brainlike chips. In the final phase, it plans to build a system of 100 such chips simulating 100 million neurons and 1 trillion synapses.

Powerful Car Alarm Simulator

November 12th, 2009 by Thomson | No Comments | Filed in Coreelectronics

A car alarm system prevents our costly cars from being stolen. A typical car alarm system sounds loudly when any one try to steal our car. The most important thing is to draw the attention of the people nearby, during an attempt of theft. If you want to deter your local thief without spending hundreds on a car security alarm? Here you can read about a CAR ALARM SIMULATOR. LED with ‘realistic-appearing’ flash sequence simulates active car alarm system.

Ingeniously simple circuit can tell if your car is running or not by detecting the voltage difference when the car is on and off.  This occurs because when your car is running the Alternator puts a out a voltage a little bit higher than when the car is off.
