Femtosecond Laser Applications for Additive Manufacturing

Posted March 01, 2017 12:00 AM by Engineering360 eNewsletter

Used for years in subtractive manufacturing for their ability to thermally ablate materials, femtosecond lasers may now have a new application: additive manufacturing technologies. The new fiber lasers could create stronger components and reduce manufacturing time and costs in the healthcare and aerospace industries.

Smart Testing of Aircraft Armaments

Posted November 30, 2016 12:00 AM by Engineering360 eNewsletter

Like other electronic systems, aircraft armaments have undergone an enormous transformation over the past few years. Testing them has become more complicated, as has verifying that a test has found all possible defects. To meet the challenge, a prime defense contractor has developed the common aircraft armaments test set (CAATS) to replace its 25 year old predecessor. This white paper describes one company's response — hardware and associated I/O that makes appropriate use of the new standard, while ensuring that conforming test equipment will not become obsolete as systems under test continue to evolve. The solution ensures accurate, comprehensive tests of aircraft during manufacturing as well as in situ after installation on the aircraft in-service.

Do Unlicensed Spectrum Communications Interfere with Wi-Fi?

Posted October 05, 2016 12:00 AM by Engineering360 eNewsletter

Not all wireless communications live within the highly regulated licensed portions of the electromagnetic spectrum. Devices like garage door openers, wireless headsets, cordless phones, and Wi-Fi hotspots often operate in a gray area such as the white space between television channels using 4G LTE technology (LTE-U). But how can a manufacturer or user verify that an LTE-U device will coexist with its licensed counterparts in the spectrum without causing interference? This company has received approval from the Wi-Fi Alliance to provide test services for this purpose that conform to a Coexistence Test Plan now under development.

AXIe Gains Over Its Competition

Posted August 05, 2016 12:00 AM by Engineering360 eNewsletter

Modular instrumentation began to eclipse rack-and-stack solutions with the introduction of VXI as IEEE 1155 in 1993. The current leader — PXI — emerged because companies needed a standard based on the PCI bus used by conventional PCs. This white paper examines the latest upstart — AXIe. Offering density, performance, and cost benefits over PXI in many applications, AXIe has become the fastest-growing of the available alternatives. Its chassis incorporates the interface with the test system controller, leaving all of its slots for instrument modules. The author claims that AXIe delivers at least a 3:1 rack-density advantage and a 2:1 bandwidth advantage for applications that require it.
