Researchers at the National Institute of Biomedical Imaging and Bioengineering (NBIB) have created a novel, low-cost biosensor to detect Human Epidermal...

Briefs: Electronics & Computers

Researchers have developed an imaging technique that uses a tiny, super sharp needle to nudge a single nanoparticle into different orientations and capture 2-D images to help...

Briefs: Mechanical & Fluid Systems

It's hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. Sandia studies myriads of low-density materials,...

Precision Low-Speed Motor Controller

Innovators at NASA Johnson Space Center have developed a method for controlling precise motion of a brushless DC (BLDC) motor using relatively inexpensive components. Precision motors are usually quite expensive and inefficient when operating at slow speeds. Current motors are only capable of operating at...

Numerous devices in everyday life use computerized cameras to identify objects — think of automated teller machines that can “read” handwritten dollar amounts when...

Briefs: Medical

Engineers at Duke University have developed a way to extract a sequence of images from light scattered through a mostly opaque material — or even off a wall — from one long...

Briefs: Data Acquisition

A new method of X-ray scanning will allow for the visualization of many more biological molecules, providing critical information about what is inside molecules to scientists...

Briefs: Sensors/Data Acquisition

Detecting the nuances of nonverbal communication between individuals will allow robots to serve in social spaces, enabling them to perceive what people around them are doing, what moods they are...

Briefs: Imaging

Painting of surfaces having numerous facets and/or curved surfaces is a time-consuming process that requires the application of several coats (layers) of paint. Such surfaces are often found on...

Briefs: Electronics & Computers

The ability to fly at supersonic speed without producing unsettling sonic booms would re-open a path to faster commercial aviation. In pursuit of aerodynamics that...

Briefs: Photonics/Optics

Researchers at Dartmouth have found a way to make back surgery safer, faster, and more cost effective. MRIs and CT scans can help surgeons identify spine problems such as...

Briefs: Semiconductors & ICs

Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a...

Briefs: Medical

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a non-invasive imaging technique that accurately detects skin cancer...

Briefs: Imaging

For more than 100 years, X-rays have been used in crystallography to determine the structure of molecules. At the heart of the method are the principles of diffraction and superposition,...

Briefs: Imaging

A stainless steel alloy — alloy 709 — has potential for elevated-temperature applications such as nuclear reactor structures. It is exceptionally strong and resistant to damage when exposed to...

Briefs: Manufacturing & Prototyping

The ability of additive manufacturing to manage small volumes, create complex designs, and fabricate lightweight but strong structures makes it a natural fit for aerospace...

Briefs: Medical

A device that shows the difference between healthy fingers and arthritic fingers has been developed that combines ultrasound and photoacoustics medical imaging techniques. Combining these...

Briefs: Test & Measurement

Automated Fiber Placement (AFP) machines can be susceptible to tow-tape defects such as gaps and overlaps. These can reduce strength between 7% and 32%....

Briefs: Test & Measurement

Trained rescue dogs are the best disaster workers — their sensitive noses help them track down people buried by earthquakes or avalanches. But dogs need breaks. A new measuring device is always...

Briefs: Imaging

A process has been developed that enables the production of a 2-mm flat camera. The lens is partitioned into 135 tiny facets, similar to the eyes of an insect. The facetVISION camera is...

Briefs: Imaging

A blue-light imaging method was developed that can be used to obtain visual data from large test fires where high temperatures could disable or destroy conventional electrical and mechanical sensors. The...

Low-Light Night Vision Imaging and Video Capture

Conventional night vision goggles all use image intensification (I2) tube technology that multiplies ambient, visible, and near-infrared light several thousands of times, allowing a user to see and operate in very-low-light conditions. One shortcoming of I2 tube night vision devices is that they...

Briefs: Medical

Medical image registration is a common technique that involves overlaying two images, such as magnetic resonance imaging (MRI) scans, to compare and analyze anatomical differences in great...

Active Pointing Monitor for a 2-Axis Optical Control System

NASA Goddard Space Flight Center has developed a pointing measurement detection and control system that monitors the real-time optical axis motions (such as tip and tilt) that affect image quality in aerial platforms. To date, there is no known real-time optical image alignment and...

Briefs: Sensors/Data Acquisition

Many low-cost sensors (or cameras) may spatially or electronically under-sample an image. Similarly, cameras taking pictures from great distances, such as aerial photos, may not obtain detailed...
