Flexibility in Low-Cost Microphone Array Systems

As more and more production items are required to comply with a variety of environmental standards, noise control is increasingly key to successful market placement. Effective control of testing costs is equally as critical as deployment of the systems themselves. The ADLINK's fully modular solution provides flexible configuration based on actual demand, while substantially reducing implementation costs, for highly efficient and precise measurement with minimal investment.

Connecting the Unconnected: Evolving Manufacturing Connectivity, Part I - Challenges to Brownfield Development

Learn about common obstacles encountered on the road to connected manufacturing, and preview some solutions provided by ADLINK and Intel. Cisco estimates that 92% of the 64 million manufacturing machines in worldwide operation are unconnected to any network, despite remaining in full use on production lines everywhere. To prevent considerable costs being incurred, viable optimization of existing machines embodies connection to the Internet, effectively integrating them into Smart Factory systems while maximizing acquisition and analysis of operational data, all within acceptable cost constraints.

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.

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

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.

Fabrication of Freeform Optics

Freeform surfaces on optical components have become an important design tool for optical designers. Non-rotationally symmetric optical surfaces have made solving complex optical problems easier. The manufacturing and testing of these surfaces has been the technical hurdle in freeform optic’s wide-spread use. Computer Numerically Controlled (CNC) optics manufacturing technology has made the fabrication of optical components more deterministic and streamlined for traditional optics and aspheres. Optimax has developed a robust freeform optical fabrication CNC process that includes generation, high speed VIBE polishing, sub-aperture figure correction, surface smoothing and testing of freeform surfaces. Metrology of freeform surface is currently achieved with coordinate measurement machines (CMM) for lower resolution and interferometry with computer generated holograms (CGH) for high resolution irregularity measurements.
