The following sections describe the design of a foam impact
attenuator to satisfy weight reduction requirements for the Formula SAE racing car.
For the past ten years, NIST has used high-reflectivity, optical choppers as beamsplitters and
attenuators when calibrating the absolute responsivity and response linearity of detectors used with high-power CW lasers.
The input Lange splitter is followed by symmetric 50 [ohm] microstrip transitions tapering down to the two balanced I and Q
attenuators. Each balanced
attenuator consists of four Lange couplers, two in a splitter/combiner pair and two in the reflective
attenuators.
Both of these strains had the C to T mutation at position +58 of the
attenuator. This mutation would appear not to influence the development of the attenuation loop.
The chopper wheel, thus, acts as an
attenuator for radiation going to the test detector.
This means that the
attenuator must se ttle at the correct level with the required accuracy during the minimum interpulse time.
Since these conical-profiled noise
attenuators are far less bulky and weigh less than the mufflers previously used, they can be elevated even in cyclonic areas for further ground-level noise and radiant-heat reduction.
The reason this crash was so severe is that the crash
attenuator, a highway safety barrier which is designed to reduce the impact into a concrete lane divider, had either been removed or crushed in a prior accident without being replaced.
M2 EQUITYBITES-May 26, 2015-IDT adds three new RF variable
attenuator products
India, May 17 -- DiCon Fiberoptics has introduced a new optical
attenuator module for the GP750 test system, a fibre optic test system, which is able to automate optical switches and fibre optic
attenuators with plug-and-play modularity.
The model 50MAP1.2 is a DC to 2 GHz
attenuator that features 0.1 dB step size resolution and offers users a low cost solution.
