Device embedded in roadway to monitor vehicle speed and signal passing vehicles, particularly when they are exceeding the speed limit, uses vibration sensing strips set across roadway as input to electronic unit that measures speedThe speed detection system uses a group of strips placed on the road...
The first echo, seen in Figure 4 as the peak around 1989, reflects those big cohorts of baby-boomers becoming parents. The children from that peak are parenting now but the bulge is passing. However, while this explains the humps, it does not explain the revisions repeatedly pushing this ...
The idler wavelength is tunable over 486 nm. Unfortunately, when pumped by a 1064 nm laser, for type I phase-matching this exhibits idler wavelengths that are approximate to the upper-wave transparency limit which is essential to minimally invasive surgery in the spectrum wavelength near 6.45 μ...
