Handheld Optical Device Catches Early Signs of Retinal Disease

A new optical device puts the power to detect eye disease in the palm of a hand. The tool — about the size of a handheld video camera — scans a patient's entire retina in seconds and could aid primary care physicians in the early detection of a host of retinal diseases. The new design is the first to combine cutting-edge technologies such as ultrahigh-speed 3D imaging, a MEMS mirror for scanning, and a technique to correct for unintentional movement by the patient.

Bending Light with a Tiny Chip

Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects a bright, clear image onto a wall or a big screen. Such a technology may be on its way, thanks to a new light-bending silicon chip developed by researchers at Caltech.

New Infrared Technique Remotely Detects Dangerous Materials

Brigham Young University professors have developed a technique that could spot from afar whether a site is being used to make nuclear weapons. The model precisely characterizes the material in each pixel of an image taken from a long-wave infrared camera. The U.S. National Nuclear Security Administration funded the project.

Driving Simulator Helps Engineers Calculate Human Factor

Simulations are an important development tool in the automobile and utility vehicle. The properties of vehicle components, such as how they respond in an accident, their reliability, or their energy efficiency can be investigated using simulations before the first component is manufactured. Researchers developed an interactive driving simulator using RODOS (robot-based driving and operation simulator) with which realistic interaction between human and vehicle can be analyzed.

Platform Dampens Vibrations in All Spatial Directions

When scientists wish to protect sensitive measuring devices from interference, they turn to active damping or, more specifically, an isolation platform. Each of the platform's four integrated swivel-mount modules contains a sensor that measures any vibrations in all three directions and an actuator that counterbalances them in three dimensions.

Harnessing Everyday Motion to Power Mobile Devices

Imagine powering your cell phone by simply walking around your office or rubbing it with the palm of your hand. Rather than plugging it into the wall, you become the power source. Researchers at Georgia Tech have developed the first triboelectric nanogenerator, or "TENG." The team paired two sheets of different materials together — one donates electrons, and the other accepts them. When the sheets touch, electrons flow from one to the other. When the sheets are separated, a voltage develops between them.
