Robot’s Speed-of-Light Communication Could Protect You From Danger

Cornell University researchers are developing a system to enable teams of robots to share information as they move around, and if necessary, interpret what they see. This would allow the robots to conduct surveillance as a single entity with many eyes. Beyond surveillance, the new technology could enable teams of robots to relieve humans of dangerous jobs such as disposing of landmines, cleaning up after a nuclear meltdown or surveying the damage after a flood or hurricane. The project, called “Convolutional-Features Analysis and Control for Mobile Visual Scene Perception,” is supported by a four-year, $1.7 million grant from the U.S. Office of Naval Research.

Heads-up Display Improves Soldiers’ Situational Awareness

A novel technology called "Tactical Augmented Reality," or TAR, is now helping soldiers precisely locate their positions, as well as the locations of friends and foes. It even enables them to see in the dark, all with a heads-up display device that looks like night-vision goggles (NVG). In essence, TAR replaces NVG, GPS, plus it does much more.

New Products: June 2017 Aerospace & Defense Technology

Ultra-Wideband Amplifier

The Lemos (Barrington, RI) PATHPA21G is a low noise, ultra-wideband amplifier, based on GaN technology. Compact and lightweight, the PATHPA21G has good N.F, high output power P1db of 24 dbm, and high gain of 30 db. The unit can achieve even better specs if the user doesn't need the entire frequency band of 0.8-21 GHZ and only needs, for example, 6-18 GHZ. Low Current 220 mA Max. Meets MIL-STD 810F requirements. Physical dimensions are 1.20” x 0.64” x 0.45.” Weight equals 17 grams.

Verifying Structural Integrity of 3D Metal-Printed Parts

Interest in 3D printing is remaking the manufacturing landscape. Consulting firm IDC says global spending on 3D printers, both desktop and industrial, hit about $11 billion in 2015 and is forecast to reach $27 billion by 2019. Another research company (MarketsandMarkets) is saying 3D printing will experience 30% compound annual growth and reach $30 billion by 2022. In its April 2016 study, “3D Printing Comes of Age in US Industrial Manufacturing,” Price Waterhouse Coopers (PWC) says compared to two years ago, more manufacturers (52% this year compared to 38% in 2014) expect 3D printing to be used in high-volume production in the next three to five years.

Uncertainty Propagation for Force Calibration Systems

There are several labs operating throughout the world that do not follow a designated guideline for calculating measurement uncertainty for force calibrations. Realizing the need for guidance, Morehouse decided to draft this document explaining how to calculate measurement uncertainty and how uncertainty propagation for force calibration systems works.

Finding Alternatives to Cadmium in Aerospace Applications

It is both an exciting and a difficult time for the aerospace industry. While the sector is at its most buoyant with demand soaring in the commercial market, this is placing a strain on the manufacturing supply chain, and putting the MRO (maintenance, repair and overhaul) market under pressure to keep aircraft in operation for as long as possible. In addition, OEMs and MRO businesses are being forced to consider potential ever-evolving legislation, particularly regarding the use of various chemicals used in the plating process, most notably the use of cadmium. This toxic metal has long been the topic of debate in the industry, with companies facing the threat of a European ban on cadmium being extended to the global aerospace industry if studies into possible alternatives prove fruitful.

Modelling and Simulation Tools for Systems Integration on Aircraft

The provision of integrated modeling, simulation and optimization tools to effectively support all stages of aircraft design remains a critical challenge in the aerospace industry. While several breakthroughs have been achieved in this area, costly iterations are still often necessary to successfully design, develop, integrate, validate and verify the components and subsystems of modern aircraft. The high level of system integration that is characteristic of new aircraft designs is dramatically increasing the complexity of both design and verification – in particular for fault condition analysis and the implementation of defect-free software (Figure 1).

Small Form Factor Embedded Systems

New Technologies Drive Diverse Solutions

As sensor processing hardware like data converters, FPGAs and CPUs evolve to handle more channels with higher signal bandwidths, designers can develop powerful distributed signal acquisition and pre-processing subsystems in small form factor (SFF) enclosures located right next to the sensors. They connect to central processing or storage resources using wideband gigabit serial links, now often exploiting low cost, standardized optical cables and interfaces. Major benefits include high signal quality over long distance, improved maintainability, and easier insertion of new technology. Since these same benefits apply across many different applications and installations, SFF system vendors now offer a bewildering array of enclosures targeting the unique requirements of each customer.
