Released in 2009, the Audiovox VOD10PS2 was an officially-licensed aftermarket overhead DVD player for automobiles that included a built-in PlayStation 2. Manufactured by VOXX Electronics, it consists of an SCPH-9000x model PlayStation 2 integrated into the unit with a 10.2-inch (25.9 cm) display capable of displaying resolutions of up to 800x480.
The locations of lunar retroreflectors left by Apollo (A) and Luna (L) missions. Retroreflectors are devices which reflect light back to its source. Six retroreflectors were left at six sites on the Moon by three crews of the Apollo program, two by remote landers of the Lunokhod program, and one by the Chandrayaan program. [1]
One-way mirrors for upper-level observation deck viewing down into a classroom (University of Wisconsin-Eau Claire) A one-way mirror, also called two-way mirror [1] (or one-way glass, half-silvered mirror, and semi-transparent mirror), is a reciprocal mirror that appears reflective from one side and transparent from the other. The perception of ...
It is present because while these mirrors' convexity gives them a useful field of view, it also makes objects appear smaller. Since smaller-appearing objects seem farther away than they actually are, a driver might make a maneuver such as a lane change assuming an adjacent vehicle is a safe distance behind, when in fact it is quite a bit closer ...
The optical boxes were produced in three versions for 15 + 1 ⁄ 2, 17 + 3 ⁄ 4 and 19 + 7 ⁄ 8 inch [diagonal] screens. Two further sizes were available for front projection onto 44 or 52 inch screens. [13] The difference was solely the position of the tube's screen relative to the concave mirror and the optical characteristic of the Schmidt ...
A set of three mutually perpendicular reflective surfaces, placed to form the internal corner of a cube, work as a retroreflector. The three corresponding normal vectors of the corner's sides form a basis (x, y, z) in which to represent the direction of an arbitrary incoming ray, [a, b, c].
Viewing the mirror from behind the knife edge shows a pattern on the mirror surface. If the mirror surface is part of a perfect sphere, the mirror appears evenly lighted across the entire surface. If the mirror is spherical but with defects such as bumps or depressions, the defects appear greatly magnified in height.
Fiducial markers are used in a wide range of medical imaging applications. Images of the same subject produced with two different imaging systems may be correlated by placing a fiducial marker in the area imaged by both systems. In this case, a marker which is visible in the images produced by both imaging modalities must be used.
