Energy-Efficient Microchip for Long-Lasting Cell Phones and Medical Devices

Researchers at MIT and Texas Instruments have developed a new chip for portable electronics that can be up to 10 times more energy-efficient than present microchips. The chip could lead to cell phones, implantable medical devices, and sensors that last much longer when running from a battery.

Machine Vision and Smart Cameras: Powerful Tools for Machine Builders

Machine builders in this day and age are part of a fast-growing and rapidly changing industry sector. With vast improvements in commercial off-the-shelf products for measurement and control, as well as falling prices, machine builders can now take advantage of an assortment of powerful tools when implementing their designs, rather than rely on the age-old method of making a custom design for every application.

Enhancing Image Clarity in the SWIR

A chromatic or color-corrected lenses for use in the visible portion of the electromagnetic spectrum have been addressed in literature, textbooks, and industry journals as early as the 18th Century. Many of these accounts by scientists and optical designers detail a method of selecting two dissimilar materials to form an achromatic pair or doublet with the ability to greatly counter image blurring resulting from the dispersive nature of refractive optical elements. Whether these tried and true optical formulae produce equally successful results in wavelengths beyond the visible range warrants further examination.

Off-the-shelf Components Upgrade Analog X-ray Equipment

The discovery of X-rays was first reported at the end of 1895 when Wilhelm Conrad Rontgen was conducting experiments with electrostatic charges and cathode ray tubes. In 2008, we have such medical imaging technology as computed tomography (CT), magnetic resonance imaging (MRI), or positron emission topography (PET). It might sound as though x-rays are antiquated. But they’re not.
