The Uludag Racing team has used a standard impact attenuator
made from Impaxx 700 foam (Impaxx) and the weight is 700 gr.

However, since ROC ratios and attenuator
values are determined by their geometries alone (for a given surface reflectance), they can be easily machined to achieve a wide range of splitter (or attenuator
The Smith chart in Figure 6 illustrates the ideal paired complementary control signals (I/IN) for a balanced attenuator
assuming four ideal equal split (that is, 3 dB) Lange couplers and four matched PHEMT devices.
A summary of promoter and attenuator
mutations, as well as alterations in outer membrane profiles, is shown in Table 1 and Figures 1 and 2.
The operations manager for In-Line Traffic Marking Company's advocacy of truck-mounted attenuators
saved the lives of two of the company's workers several years ago.
The low-power (calibrated levels from pW to 2W) 818 series detectors operate from 200 to 1800 nm and feature matching patented, removable OD3 attenuators
for each photodetector.
MEMS-based solutions provider MEMSCAP (NYSE Euronext:MEMS) (Paris:MEMS) announced on Monday it has successfully completed die level reliability testing beyond 200m cycles on its Thermally Actuated Variable Optical Attenuators
The power is varied by either adjusting the laser power itself (if the laser output power can be stabilized at all power levels) or by using a variable high-power laser attenuator
. Ideally the output power stability should vary less than [+ or -] 0.5 % in any 15 min time period as laser power fluctuations directly affect the measurement uncertainty.
The new signal conditioning modular voltage attenuator
system, or SCMVAS, is an analog signal conditioning system designed to safely monitor and accurately measure voltage potentials up to 1,200 V peak-to-peak.
Each channel has a modulation generator, a radio-frequency (RF) generator and an attenuator
. The attenuator
can simulate the threat scan and the range loss, as well as (if appropriate) the receiving-antenna pattern.
Another important element in this noise attenuator
design is its conical exterior shape.
