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.

Torontech Group
Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications Optical fibers are very strong, but the strength is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The initial fiber strength, as well as its change with time, must be considered relative to the stress imposed on the fiber during handling, cabling, and installation for a given set of environmental conditions. There are three basic scenarios that can lead to strength degradation and failure by inducing flaw growth: dynamic fatigue, static fatigues, and zero-stress aging.

ROSS ENGINEERING CORPORATION
A key feature of our rotary switches is their simple mechanical design which results in conservative stress levels for trouble-free, long life use. In addition, each rotary switch has a reinforced chassis design utilizing G-10 or G-11 fire retardant anti-tracking coated epoxy glass insulation. G-7 silicone glass is used for special applications where RF or high temperatures are involved. Heavy duty contacts, specifically designed to minimize corona in the Ross rotaries, are made of highly conductive yet weld resistant alloy with high contact closing force. This high force gives our rotary switches high momentary current capability and a reputation for their ability to withstand high shock and vibration as well as other severe environmental conditions. Ratings to 150kV, to 200A. When immersed in insulating oil, fluid or gas, the voltage withstand value is at least doubled and the interrupt capability is much greater. In a gas atmosphere, no modification is required. However, immersion in oil or fluid may require modification in some cases, at an extra cost (optional). Each unit is either manually or electrically operated. One SPDT contact is standard on most units. The auxiliary contact is used as an interlock for protection against "Switching Hot".
