Glucose-Sensing Contact Lens Enables Noninvasive Testing

This illustration shows the schematic procedure for the fabrication of a surface-enhanced Raman scattering contact lens via transfer printing. Blood testing is the standard option for checking glucose levels, but a new technology could allow noninvasive testing via a contact lens that samples glucose levels in tears. Glucose is a good target for optical sensing, and especially for what is known as surface-enhanced Raman scattering spectroscopy.

The Economics of Accuracy in Low-cost, High-volume Sensing Applications

Various research firms forecast the market for portable medical devices to be somewhere around the $20 billion-range within the next several years. Part of the increased demand is due to an aging population with more chronic conditions. These smaller portable units requires devices with smaller footprints. By the same token, smaller devices need to provide adequate levels of care to ensure patient safety and comfort. Thus, functionality cannot be sacrificed for space.

Air Force Is Developing Mach 18 Wind Tunnel

Mike Smith, AEDC optical diagnostic physicist, verifies the Coherent Anti-Stokes Raman Spectroscopy system is functioning properly prior to conducting tests in support of risk reduction for a new test capability that will increase Mach number of AEDC Hypervelocity Wind Tunnel 9 at White Oak, Md. (U.S. Air Force photo/A.J. Spicer) The Arnold Engineering Development Center (AEDC) Hypervelocity Wind Tunnel 9 team is conducting tests in support of risk reduction for a new test capability that will be revolutionary for AEDC and the U.S. Air Force. The capability involves increasing the Mach number of what AEDC is currently able to achieve at Tunnel 9 in White Oak, Md., from Mach 14 to Mach 18.

Software Gives Bomb Techs X-Ray Vision

In a training session, bomb techs use Sandia National Laboratories’ XTK software to stitch together X-ray images of a suspicious package. The XTK team spent hundreds of hours with Explosive Ordnance Disposal technicians learning how they work. (Photo courtesy of the National Nuclear Security Administration) In the chaos that followed the terrorist attack at the 2013 Boston Marathon, bomb squads scanned packages at the scene for explosive devices. Two homemade pressure cooker bombs had killed three people and injured more than 250, and techs quickly had to determine if more were waiting to blow up.
