SWaP-C and Why Your Component Partner Matters

The military is continually pushing to decrease the size, weight, power and cost (SWaP-C) of its electronics, particularly for items carried by the troops. To meet these goals, everyone involved in designing and manufacturing the device needs to work together closely to ensure maximum efficiency of every component. This makes choosing the right partner crucial. Our white paper explores why SWaP-C is so important and includes information on:

Automakers Use 3D Printing to Reap Benefits of Lower-Cost Tooling and More Efficient Assembly

3D printing, also known as additive manufacturing, has existed since the 1980s, but has recently been more widely adopted. In the span of a decade, 3D printers have moved from an optional piece of equipment for producing relatively simple prototypes, to an absolute necessity — one that is transforming the automotive industry in fundamental ways, This white paper highlights 3D printing applications in automotive today, and what’s coming tomorrow.

Optimizing Next-gen Machine Vision Platform To Enhance Automated Inspection

With machine vision’s development and growth in the Industry 4.0 environment, the higher computing performance becomes essential to acquire high resolution images at high speeds, and expanding FOV (field of view). The associated hardware must therefore significantly enhance reliability, to guarantee smooth operation of the production line. Read this white paper to know more about characteristics the next-gen machine vison platform need.

Low-Power-Consumption, Single-Mode Quantum Cascade Lasers Fabricated Without Epitaxial Regrowth

These low-power lasers can be used for spectroscopy instruments in health and safety monitoring, and industrial process monitoring.Quantum cascade (QC) lasers employ intersubband electronic transitions in semiconductor quantum well structures to generate emission at specific engineered wavelengths. QC devices have been particularly successful as mid-infrared emitters in the 4- to 12-μm wavelength range, a spectral regime that is difficult to access with interband diode lasers. As cascade devices, QC lasers can also be designed with many gain stages, which, combined with optimized doping and optical design, has enabled the development of lasers with remarkably high continuous output power (in excess of 1 W). One of the most important applications of mid-infrared QC lasers is quantitative gas detection using absorption spectroscopy, where a single-frequency laser is used to interrogate specific absorption lines of a target compound. While high output power is essential in certain applications, many in situ absorption spectrometers require only milliwatt-level output to effectively measure low levels of compounds of interest with strong absorption lines in the mid-infrared regime.

A Versatile Three-Dimensional Printing Approach

This technology can generate integrated circuits, electrical connectors, supercapacitors, and flow cell batteries.NASA has developed a versatile method and associated apparatus for constructing and using a conductive filament in various applications of 3D printing. It uses an attractive polymer formulation, which exhibits low melting temperature even when combined with conductive material, as the printing filament material. It may be used with a commercial 3D printer to generate custom 3D conductive geometries, such as integrated circuitries, electrical connectors, supercapacitors, and flow cell batteries. This invention can be used to create conductive, piezoelectric, or multifunctional materials using three-dimensional printing, with relatively low melt or glass transition temperatures. This invention should be useful wherever such materials are needed, with modest fabrication costs.

Puncture-Healing Thermoplastic Resin Carbon-Fiber Reinforced Composites

This technology self-repairs following low- to mid-velocity impacts. A through-transmission C-scan of the healable composite panel shows the material post-impact (top) and post-healing cycle (bottom). NASA’s Langley Research Center has developed carbon fiber reinforced composites with self-healing properties. The initiation and propagation of damage to carbon composites, such as in aircraft structural components, results in component failure. Typical structural repairs result in damaging practices, where material is ground away and holes are drilled to secure patches, which can act as new sites for damage. This technology exhibits effective self-repair that heals quickly following low- to mid-velocity impacts, while retaining structural integrity.
