Circuit Design Tool

Sunstone Circuits, Mulino, OR, announced DFMplus, a Design to Manufacturing tool that allows potential issues to be fixed in the PCB design phase. The tool helps users verify PCB designs before ordering. The tool features a preview of possible failure points, provides efficient transfer of design file data into manufacturing, and enables designers to submit partial designs, or regions of the design, as a section-by-section check.

Computed Tomography Systems

JG&A Metrology Center (Detroit, MI) introduced increased flat panel sizes for computed tomography (CT) systems. Cone beam systems now utilize flat panel technology and scan parts up to 14" (350 mm) in diameter. With increases in LDA sizes as well, the CT systems use line detector array technology when scanning parts up to 26" (650 mm) in diameter. The equipment is used to provide 3D internal part inspection using industrial CT equipment.

Google Glass for Industrial Automation

A new concept uses Google Glass for operating machinery, with all of the benefits delivered by wearable computing in an industrial environment. With Google’s Web-enabled glasses, status or dialog messages can be projected via a head-up display directly into a person’s field of vision. Online information and communication is also possible with this innovative device, and error messages can be acknowledged using a touchpad.

Mechanically Induced Nucleation Improves Crystalline Quality During Melt Growth of Semiconductors

Significantly lower supercooling results in the ideal growth condition of single crystal nucleation. Marshall Space Flight Center, Alabama For certain semiconductors with important applications, the existing bulk crystal growth technique from the melt usually results in poor-quality multi-crystalline ingots that cause the typically low yield of the commercial growth process. The low-quality, multi-grained crystal growth is mainly caused by the large supercool of the melt, which prohibits the ideal growth condition that a small, single-crystal nucleus forms at the very tip and grows into a large single crystal. For instance, semi-insulating cadmium zinc telluride (CdZnTe) crystal is a highly promising material for room-temperature x-ray and gamma ray detectors. However, the major hurdle in using the CdZnTe crystals is its cost. The ability to pack many data acquisition channels (hundreds) with the stopping power for high-energy radiation requires large single crystals of CdZnTe.

Fabrication of a Nanopipette Array for Biosensing

Ames Research Center, Moffett Field, California Development of biosensors is an active field due to a wide range of applications in lab-on-a-chip, diagnostics of infectious diseases, cancer diagnostics, environment monitoring, biodetection, and others. One of the strategies used for selective identification of a target is to preselect a probe that has a unique affinity for the target, or can uniquely interact or hybridize with the target — a lock and key approach. In this approach, one then needs a platform to support the probe and a recognizing element that can recognize the said interaction between the probe and the target. Electrical readout biosensors have gained much attention because, in principle, they can be made more compact than optical technologies.

Products of Tomorrow: January 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Variable-Sweep-Wing Aircraft Configuration

There are significant improvements in structural, aerodynamic, and energy efficiency. Ames Research Center, Moffett Field, California Efficient aircraft designs are increasingly desired in order to support the continued growth of the air transportation industry. Continued expansion of this vital mode of transportation is threatened due to concerns over ever-increasing emissions, noise, and the demand for fuel. Current airport runway, ramp, and terminal facilities are increasingly constrained by encroaching growth and neighborhood environmental issues. The challenges associated with ever-increasing demand for air travel will require the development of aircraft that can fly efficiently over wide speed ranges, minimize their environmental impacts, offer the potential for sizing and growth relative to market demand, and make efficient use of constrained airport and airspace resources.
