Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Trimble Navigation was founded in November 1978 [2] by Charles Trimble and two partners from Hewlett-Packard. It initially operated above a movie theatre in Los Altos, California In 2002, Caterpillar and Trimble formed a joint venture Caterpillar Trimble Control Technologies (CTCT), to develop machine control products for improved customer ...
Modern video/image rendering programs use a similar technique to achieve the anaglyph effect. Modern anaglyphic rendering programs used to use simulated filters over the virtual cameras, for Red/Cyan anaglyphs the left camera blocking all but red light being perceived and the right blocking all but the blue and green light being received.
The cap is red on ThinkPads, but is also found in other colors on other machines. It may be gray, pink, black or blue on some Dell models, blue on some HP/Compaq laptops, and green or gray on most Toshiba laptops produced before the 2000s. Button configurations vary depending on vendor and laptop model.
Optical triangulation with the BC-4, PC-1000, MOTS, or Baker Nunn cameras consisted of photographic observations of a satellite, or flashing light on the satellite, against a background of stars. The stars, whose positions were accurately determined, provided a framework on the photographic plate or film for a determination of precise ...
Blue cone monochromacy is a severe condition in which the cones sensitive to red or green light are missing or defective, and only S-cones sensitive to blue light and rods which are responsible for night vision are functional. [1] [2]
This gravitational model is complete to spherical harmonic degree and order 2159 (block diagonal), and contains additional coefficients extending to degree 2190 and order 2159. It provides a raster of 2.5′×2.5′ and an accuracy approaching 10 cm. 1'×1' is also available [ 7 ] in non-float but lossless PGM , [ 5 ] [ 8 ] but original .gsb ...
The geometrical separation between it and the reference ellipsoid is called the geoidal undulation, or more usually the geoid-ellipsoid separation, N. It varies globally between ±110 m. A reference ellipsoid, customarily chosen to be the same size (volume) as the geoid, is described by its semi-major axis (equatorial radius) a and flattening f.
