In geometry , a triangulation is a subdivision of a geometric object into simplex simplices . In particular, in the plane it is a subdivision into triangle s, hence the name. Triangulation of a 3 dimensional volume would involve subdividing it into tetrahedrons pyramids of various shapes and sizes packed together. In most instances the triangles of a triangulation are required to meet edge to edge and vertex to vertex. Different types of triangulation may be defined, depending both on what geometric object is to be subdivided and on how the subdivision is determined.

Optical Triangulation Sensors are commonly used to provide door mounted safety detection on swinging automatic doors. In North America , these types of sensors are very common and manufactured in very high volumes. When automatic swinging doors open and close, it is important that they do not come into contact with pedestrians passing through the door. Sensors used in the automatic door industry typically fall into four categories Microwave Sensors used to detect motion of a person as they approach an automatic door, Reflective Optical Sensors that are mounted on the door header and detect the presence of a person in the door path Camera based sensors that are also mounted on the door header and detect presence a competing technology to Reflective Optical Sensors and Triangulation sensors which are mounted on the door and move with the door to provide safety. Reflective and Camera technologies do not perform well on moving swing doors, because they typically depend upon detection of changes in the background. A sensor mounted on a swing door system is constantly in motion, so the background i.e. floor beneath the door changes continuously. To overcome this problem, a triangulation sensor provides an innovative solution. Triangulation Sensor Functionality In most cases an optical triangulation sensor is mounted near the top of the swinging door frame, inside a long extruded aluminum tube with an optical window facing the floor. An nowrap 880 nm Light emitting diode LED light source emits a collimated light beam that is emitted from the sensor, bounces off the floor and is received by a photodiode positioned adjacent to the LED source. A second photodiode or a linear array of photodiodes is positioned farther along the length of the sensor. When the emitted beam bounces off the floor, the reflected energy is almost exclusively concentrated on the first adjacent photodiode ..., hence averting a collision and providing safety. Triangulation sensors are found on a number of door ... more details

Unreferenced date December 2009 Stellar triangulation is a method of geodesy which uses cosmic instead of terrestrial targets. It was first done by the Finnish geodesist Yrj V is l V is l in 1959, who made astrometric photograph s of the sky at two stations together with a balloon probe between them. Even this first step showed the potential of the method, because V is l got the azimuth between Helsinki and Turku a distance of 150 km with an accuracy of 1 . Soon the method was successfully tested by External ballistics ballistic rockets and for some special satellites. Adequate computer program s were written for the astrometric reduction of the photographic plates, the Intersection set theory intersection of the observation planes containing the stations and the targets, and the adjustment of stellar terrestric networks with Data redundancy redundancy . The advantage of stellar triangulation is the possibility to cross far distances terrestrial observations are restricted to approx. 30 km, and even in high mountains to 60 km , and the independency of the Earth s gravity field. The results are azimuth s between the stations in the stellar inertial system , despite of no direct Line of sight propagation line of sight . In 1960 the first appropriate space probe was launched the 30 m diameter balloon satellite Project Echo . By then the whole of Western Europe could be linked together geodetically with accuracies 2 10 times better than by classical triangulation . During the late 1960s a global project was begun by H.H.

Triangulation is a chess tactics tactic used in chess to put one s opponent in zugzwang . That is, it gets to the same position with the other player to move, when it is a disadvantage for that player to move, e.g. he has to give up a blockade and let the other player penetrate his position. Triangulation is also called losing a tempo chess tempo or losing a move . Triangulation occurs most commonly in Chess endgame endgames with only king chess kings and pawn chess pawns when one king can maneuver on three adjacent squares in the shape of a triangle and maintain the basic position while the opposing king only has two such squares.

A S Aero was a Norway Norwegian airline company founded by Tancred Ibsen in January 1920. The company was financed by Tancred Ibsen s uncle, businessman Einar Bj rnson, and two shipowners. Despite the A S for private company limited by shares in its name, A S Aero was never formally registered as a limited company. The company purchased one Hansa Brandenburg W.29 and four Friedrichshafen FF.49 aircraft from Germany in February. This deal was probably illegal as the Triple Entente Entente prohibited the export of German surplus aircraft, but Ibsen nevertheless got permission from the Norwegian Ministry of Defence to import the five German aircraft. During the summer of 1920 A S Aero successly operated demonstration, advertising, and limited mail flights from the Bestumkilen bay in Oslo, with Tancred Ibsen as the head pilot. The company also chartered out airplanes to serve the Det Norske Luftfartrederi routes in southern Norway. Tancred Ibsen soon got tired of his career as a pilot, and the activity of A S Aero ended, with the company becoming part of the aircraft factory in T nsberg , A S Norske Aeroplanfabrik .

Refimprove date December 2009 A triangulation of a set of points P in the plane geometry plane is a Polygon triangulationtriangulation of the convex hull of P , with all points from P being among the vertices of the triangulation. Triangulations are special cases of planar straight line graph s. There are special triangulations like the Delaunay triangulation which is the Dual polytope geometric dual of the Voronoi diagram . Subsets of the Delaunay triangulation are the Gabriel graph , nearest neighbor graph and the minimal spanning tree . Triangulations have a number of applications, and there is an interest to find a good triangulation for a given point set under some criteria. One of them is a minimum weight triangulation . Sometimes it is desirable to have a triangulation with special properties, e.g., in which all triangles have large angles long and narrow splinter triangles are avoided . Given a set of edges that connect some pairs of the points, the problem to determine whether they contain a triangulation is NP complete Lloyd, 1977 . ref E. L. Lloyd.
