Fast Fourier Transform
Although many personal computers have four processors, Fast Fourier Transform, the complex mathematical equation computers use to process sound and images, is calculated on just one processor. Dale Mugler’s new mathematical formula dramatically increases a computer’s operating speed by allowing multiple processors to contribute to the calculation. This improvement could be especially important for MRI and CT imaging, as well as X-ray crystallography.
Known more formally as a miniaturized sensing system for the detection of heart failure, Fred Choy’s microchip maps and analyzes sounds to detect early signs of heart failure. The device identifies two sounds present only in heartbeats patients experiencing cardiac distress.
