Coming Soon - ASTM D4169: A Historical Perspective, plus Review and Implications of D4169-16

WESTPAK's protective package system testing professionals present a webinar focused on ASTM D4169. We begin with a historical perspective of D4169 and its origin to provide you with a background on protective package testing protocols. Then we review D4169-16 and compare it against the prior revisions. We discuss options available if your test fails the –16 revision after passing prior revisions. Live Q&A will be included during the broadcast.

ABLE TECHNICAL GUIDE: Your Solution to 7 Metal Surface Problems

Electropolishing is often referred to as a “reverse plating” process. Electrochemical in nature, electropolishing uses a combination of rectified current and a blended chemical electrolyte bath to remove flaws from the surface of a metal part.

The Evolution of ADAS: Testing Systems That Include Cameras, Radar, and Sensor Fusion

In Conjunction with SAE

On their own, test requirements for camera and radar technology are rapidly changing as they become more safety critical. Because these systems are increasingly reliant on sensor fusion techniques, the test requirements are growing even more complex at a fast rate. A test system built on a scalable and flexible architecture is the only way to make sure you can adapt as quickly as ADAS technologies and autonomous vehicle systems are evolving.

Pulsed Phase Noise Measurements: Challenges and Solutions

Thanks to advances in digital signal processing techniques, wireless communications and radar systems have become increasingly digital. Constraints have also been placed on packing more information into less bandwidth. For both systems, one of the key RF parameters that limits performance is phase noise.

Coming to a Lab Bench Near You: Femtosecond X-Ray Spectroscopy

Upon light activation (in purple, bottom row’s ball-and-stick diagram), the cyclic structure of the 1,3-cyclohexadiene molecule rapidly unravels into a near-linear shape in just 200 femtoseconds. Using ultrafast X-ray spectroscopy, researchers have captured in real time the accompanying transformation of the molecule’s outer electron “clouds” (in yellow and teal, top row’s sphere diagram) as the structure unfurls.

The ephemeral electron movements in a transient state of a reaction important in biochemical and optoelectronic processes have been captured and, for the first time, directly characterized using ultrafast X-ray spectroscopy at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Like many rearrangements of molecular structures, the ring-opening reactions in this study occur on timescales of hundreds of femtoseconds (1 femtosecond equals a millionth of a billionth of a second). The researchers were able to collect snapshots of the electronic structure during the reaction by using femtosecond pulses of X-ray light on a tabletop apparatus.

Infrared 3D Scanner Measures Like Human Vision

With the new infrared 3D scanner, people can be measured without disturbing projections. (© Photo Fraunhofer IOF)

A 3D scanner, with a resolution of one million pixels and real-time data processing, operates using measuring technology that works in a similar way to human vision. To detect an object, periodic patterns are projected onto the surface using a specially developed near-infrared projector. A sequence of different patterns is projected in rapid succession in order to record as many measurement points as possible by the two cameras.

Architectures for Implementing a Hardware-in-the-Loop System

Safety, availability, or cost considerations can make it impractical to perform all the necessary tests with the complete embedded control system. Using hardware-in-the-loop (HIL) simulation, you can simulate the parts of the system that pose these challenges. By thoroughly testing the embedded control device in a virtual environment before proceeding to real-world tests of the complete system, you can maintain reliability and time-to-market requirements in a cost-effective manner even as the systems you are testing become more complex. Download this whitepaper to find out more about implement a HIL system into your test environment.

In-Situ Load System for Calibrating and Validating Aerodynamic Properties of Scaled Aircraft in Ground-Based Aerospace Testing Applications

ILS improves testing accuracy, repeatability, time in tunnel, and many aspects of the calibration process.

The in-situ load system (ILS) provides the ground-testing community with a comprehensive tool that permits system-level calibration and validation of force measurement systems in a test-like environment. It was developed to improve testing accuracy, repeatability, time in tunnel, and many aspects of the calibration process. The key innovations are that ILS enables a system calibration (rather than independent subsystem and component calibrations) by using the one-force-vector calibration approach and a statistically defensible estimate total force measurement uncertainty. ILS may be applied in any wind tunnel facility, private or government.
