Furthermore, we may acknowledge that one of the signatures of such a beacon is the presence of its eclipse, for the interruption of the light makes it a signal rather than a constant.
A photoelectric sensor and an infrared light beamer (Velleman PEM10D, NL) were integrated into the simulator, in order to determine when the participants decided to cross the street, by detecting the interruption of the light beam (Fig. 1a).
It's an in-glass solution they call planar scatter detection — which I'm choosing to understand as detecting interruptions of infrared light suffusing the glass (like the FTIR mouse).
Interruptions of the light path by pollen grains were detected by a silicon photocell after optical magnification and converted into electric pulses.
Kanaan set the target with a lap of 160.052 miles an hour and, after a 40-minute interruption of qualifying because of light rain, Castroneves threw a scare into his pal.
Although the ambient nocturnal illuminations were at an appropriate level to allow normal melatonin secretion [ 48], we did not have an accurate measure of light interruptions.
Environmental disturbances were documented based on a locally derived scale composed of light interruptions, clinical activities, and use of invasive instrumentation (Additional file 1).
To fake this symptom, close or squint your eyes, appearing as if the presence of light or interruption of noise it too much for you.
Upon interruption of the run, the light intensity was reset to baseline.
Interestingly, these rats showed increased activity during specific time-points of the dark phase, as well as peaks of activity with interruption of rest during the light phase.
