v. t. e. In legal terminology, the assured clear distance ahead ( ACDA) is the distance ahead of any terrestrial locomotive device such as a land vehicle, typically an automobile, or watercraft, within which they should be able to bring the device to a halt. [1] It is one of the most fundamental principles governing ordinary care and the duty ...
The blue field entoptic phenomenon is an entoptic phenomenon characterized by the appearance of tiny bright dots (nicknamed blue-sky sprites) moving quickly along undulating pathways in the visual field, especially when looking into bright blue light such as the sky. [ 1] The dots are short-lived, visible for about one second or less, and ...
Eye tracking device is a tool created to help measure eye and head movements. The first devices for tracking eye movement took two main forms: those that relied on a mechanical connection between participant and recording instrument, and those in which light or some other form of electromagnetic energy was directed at the participant's eyes and its reflection measured and recorded.
Superluminal motion. In astronomy, superluminal motion is the apparently faster-than-light motion seen in some radio galaxies, BL Lac objects, quasars, blazars and recently also in some galactic sources called microquasars. Bursts of energy moving out along the relativistic jets emitted from these objects can have a proper motion that appears ...
We've all grown up thinking that sitting too close to the television is damaging to our eyes ... but that might not be the case. Technology spawns lots of confusion ... and a few affectionately ...
However, J.D. Power's study with newly incorporated repair data shows EVs, as well as plug-in hybrid electric vehicles (PHEVs), require more repairs than gas-powered vehicles in all repair categories.
For Saturday, skywatchers will need to grab a small telescope since the asteroid isn’t bright enough to be seen with the naked eye. And it’ll be moving quickly across the southern sky, making ...
The three visual effects listed above (distraction, glare and flash blindness) are minimized during the day since the eye is not dark adapted, and since visible lasers are not often used outdoors in daytime. Motion and speed of the aircraft. A slow aircraft is at greater risk than a fast one (relative to travel across the viewer's line of sight).
