Reticulated Foams Expand The Boundaries Of Cellular Solids

Ideally suited for high-tech applications, reticulated foams of ceramic or metal provide industry as well as the research community with an extraordinarily versatile material form that can be engineered for particular properties and tailored for specific applications. The interconnected lattice of continuous ligaments within the cellular structure provides greater strength than shorter fibers and also ensures uniform material characteristics throughout the structure.

Healthy Sensing: Do You Know When Your Proximity Sensor Is Sick?

The age of the fully connected aircraft is upon us and it isn’t coming a minute too soon to meet the demands of today’s commercial aircraft. The integration of smart components helps to increase revenue and reduce the cost to serve. Honeywell has designed and implemented the patented FAVCO (Fixed Amplitude Variable Current Oscillator) technology, which allows for continuous health monitoring capable of detecting the majority of circuit and sensor faults.

AGM Thumbtack™ Valves for Small Enclosures: Smaller and Drier

Sensitive equipment such as optics and electronics can be damaged by humidity and condensation. Placing moisture-sensitive equipment inside a sealed enclosure reduces the risk of damage, but temperature and pressure variations can be problematic for a sealed enclosure if it does not have a pressure-relief mechanism.

How to Manage Heat in Modular, COTS Enclosures

As components shrink, embedded systems have made their way into smaller and more mobile applications. Systems need to withstand more intense vibration, shock and EMI parameters and still function effectively. All of this affects the ruggedization of enclosures.

Metal Bellows - Key Enabling Technology for a Wide Range of Engineering Applications

Convert pressure, mechanical, vacuum and temperature changes into linear or rotational motion using metal bellows. It may be the smallest component of an overall machine assembly but it very often plays the most critical role in the functionality of a system. This newest whitepaper from Servometer outlines seven key enabling technologies that benefit from bellows across a wide range of engineering applications – providing a more precise, more reliable or less costly alternative to an existing engineering solution.

Acrylate-Based Specialty Optical Fiber Coatings for Harsh Environments

Applications of optical fibers at high temperatures and in harsh environments demand coatings sustainable under those conditions. The goal of this work was to evaluate thermal and environmental stability of a series of commercially available and in-house formulated acrylate-based coatings. Dual and single-coat fiber designs were tested. The individual formulations included non-urethane and urethane acrylates, silicone acrylates and an organic-inorganic hybrid acrylate. The “as drawn” fibers were tested for attenuation, mechanical reliability, microbend sensitivity, delamination resistance and coating stripability. Thermogravimetric analysis (TGA) was used for estimating the use temperature of the coatings. In addition, the fibers were exposed to harsh environments, including dry aging in air (150°C) and in nitrogen (250°C), autoclaving, immersion in high pressure/temperature water (up to 200°C and 2000 psi) and immersion in a hot cable gel (160°C). Based on the obtained results, the best formulations were ranked for suitability in different types of fiber application.
