Batteries are the new fuel tanks in electric vehicles (EVs). However, they are highly complex systems requiring advanced engineering methods from chemistry to cell engineering to module and pack engineering, and finally to integration into full vehicles. They need to store as much energy as possible to...

One of the challenges in electric drive engineering is to ensure acoustic passenger comfort. Electric machines and gearboxes can produce tonal noises that are perceived as unpleasant.

Coined the “PELTIER EFFECT” after its discoverer, Jean Charles Athanase Peltier, thermoelectric cooling has been utilized in marketable products for decades. Such products have a history of being used in “new” applications. In the 1970s, thermoelectric elements were cooling components in NASA...

The next generation of automobiles are integrating new electronic elements for improved safety, connectivity, and clean energy consumption. With the dramatic increase in the number of electronic components, new vehicles need to be optimized power efficiency, sensor fusion, communications, high-power...

This white paper looks at how hypersonic flight will place radical new demands on the embedded computing systems on which they will rely – in terms of not only new levels of performance, but also of new levels of ruggedness.

Demonstrations of increasingly connected and automated heavy vehicles on public highways and bustling worksites are becoming more commonplace, as the commercial vehicle industry continues to pursue improved fuel efficiency and operator productivity while...

Hotwatt has manufactured specialized electric heating elements for over 64 years, all made in the USA. Products include cartridge, air process, immersion, strip and finned strip, tubular and finned tubular, band, compressor crankcase, foil, flexible rope and ceramic heaters. We are a quality supplier to OEM's in the in...

NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....

NASA's Langley Research Center has developed a patented SansEC sensor technology for use in many different areas, including tall structures and wind turbines. The SansEC technology is a proven wireless sensing platform capable of measuring the electrical impedance of physical matter in proximity to the...

Mandal, along with Professors Yuan Yang and Nanfang Yu, built upon earlier work demonstrating that many simple plastics and polymers are excellent heat radiators that could be used for passive radiative daytime cooling (PRDC). Their challenge...

Rapid adoption of mobile platforms such as smartphones and tablet computers has increased the range of applications and data on mobile devices. The use of these devices to communicate sensitive or confidential data requires, among other things, strong front-end user authentication procedures and/or protocols...

This software fits trajectory ephemerides and thrust profiles with a Chebyshev polynomial representation, and stores this fit in data files suitable for upload to a spacecraft. In addition, a number of utility modules are provided to assist with inspection and diagnosis of issues with data...
