ELWIS -
Autoneum Holding AG
ELWIS (Evaluation of Light Weight Impedance System) offers a full and rapid characterization of porous materials based on the analysis of a single sample. The ELWIS system consists of the ELWIS-A and ELWIS-S components which can be used independently from each other although both applications are needed for a complete material simulation.ELWIS-A measures acoustic parameters that are needed to evaluate the acoustic performance of sound insulation and sound-absorbing multi-layer materials. An additional impedance tube for absorption measurements at higher frequencies is available for ELWIS-A.ELWIS-S measures structural parameters that are needed to simulate the dynamic and acoustic behavior of sound packages in the medium to low frequency range (including the "Poisson Ratio" for foam materials).ELWIS is very easy to operate: Thanks to its user-friendly software, the system can also be used to obtain reliable results by users with only limited experience in the characterization of porous materials.

Teledyne Defense Electronics
As the OEM of all of our products, both end items and support equipment, Teledyne can support all repair needs for end users. Turn-around times are typically less than 90 days with units being returned fully tested to their specific program requirements. All repairs are performed using new materials and components. Once the repair has been received, and purchase order issued, a Test and Evaluation report is sent to the end user fully describing our findings and the proposed repair.Following live ejections, Teledyne will download and prepare a post ejection report for any of our ejection seat sequencers AT NO COST to the end user. This report will document the data stored in the flash memory of the unit. The data will be a representation of what the sequencer recorded. However, Teledyne is unable to give any opinions or technical advice on the operation of the seat system.

Applied Image, Inc.
Sinusoidal Target Arrays have been recognized as a superior test method for a variety of applications, from moiré contouring to reliable MTF Evaluation of materials, lenses, cameras, and electro-optical systems (Follow the hyperlink to learn about using Sinusoids for MTF eval). Sinusoidal Pattern Arrays are manufactured on two different materials for both reflective and transmissive applications. Because of the inherent limitations of reflective materials, the maximum spatial frequency of the reflective pattern arrays is limited to 20 cycles per mm, while the transmission film arrays are offered in various sizes up to 256 cycles per mm. In addition, the sinusoidal arrays are available in a Single Frequency Grating or with Multi-Frequency Gratings. If instead of continuous sinusoidal frequency, you are looking for a square wave frequency design, then look to the Ronchi Gratings page. Should you need to alter the size of the pattern or the substrate, fill out our Custom Test Targets and Charts form and start the conversation.

CVS Trevista X4 -
STEMMER IMAGING Ltd.
The fourth generation of CVS Trevista Surface, Cylinder and Multiline surface inspection systems from Stemmer Imaging features brighter illumination to enable faster image acquisition and have a larger measuring field. The new Trevista X4 models utilize a 2.5-D process, called "Shape from Shading," and are especially suited to the examination of components with shiny and diffusely scattering surfaces. Surface defects such as scratches, burrs, dents, discoloration or grinding marks, even if only a few micrometers deep, can be detected with significantly greater certainty with this process than with conventional image processing systems, according to the manufacturer. The X4 generation offers structured, diffuse dome illumination that is brighter by a factor of 2.5 compared with the previous models, enabling faster image acquisition. For a typical image size of four megapixels, evaluation using the Trevista algorithm takes place around 20% faster than before, which results in potentially lower cycle times.

Verified Systems International GMBH
The test system cluster architecture is based on dual CPU or 4-CPU PCs acting as cluster nodes. The nodes communicate and synchronise over a high-speed network (Myrinet or InfiniBand). A modification of the Linux operating system allows to run the test execution and evaluation algorithms in hard real-time on reserved CPUs, where scheduling is non-preemptive and controlled by the test system itself. The interrupts caused by interfaces to the system under test may be relayed to CPUs designated explicitly for their handling. This approach offers the opportunity to utilise high-performance standard hardware and the services provided by the widely accepted Linux operating system in combination with all mechanisms required for hard real-time computing. The cluster architecture presents an opportunity to distribute interfaces with high data throughput on different nodes, so that PCI bus overload can be avoided. In addition, the CPU load can be balanced by allocating test data generators, environment simulations and checkers for the behaviour of the system under test ("test oracles") on dedicated CPUs.

National Technical Systems
NTS has a number of facilities capable of conducting dual shaker testing, vibration testing utilizing multiple electrodynamic exciters, for the evaluation of large payloads.Once such example was conducted as part of the test program for NASA’s Lunar Atmosphere and Dust Environment Explorer or LADEE. NTS worked with NASA’s Ames Research Center for simulated environmental testing of the LADEE observatory which included dual shaker vibration.Vibration testing on the observatory was conducted utilizing the NTS Santa Clarita facilities tandem Ling B-340 electrodynamic exciters. These exciters allow either dual shaker vibration testing, or in the case of the LADEE observatory tests, they minimize the test set-up time. The electrodynamic exciters were staged with one in the thrust axis and the other set-up for lateral axes vibration. This dual shaker set up allowed for a quick transition from one test to the other. During the tests, the vibration test lab was maintained at a class 10,000 cleanliness level.
