[2] [3] Dispatchers at a central facility used a compass rose to mark lines of position from each reporting tower onto a large map to quickly find where the reported bearings intersect. Today, a more precise determination of a fire location can be made by the use of a single Fire Finder in conjunction with a digital elevation model (DEM). [4]
Center finder. A center finder is a tool used to align the machining center to a precision location on a work piece. Often these locations might be marked using a layout method (coating the surface with layout stain and scribing a precise location with the intersection of the two lines identifying the position to be machined, etc.
Klein Tools got involved in motorsports in 1994 to gain visibility with auto racing fans. [11] Drivers of Klein-backed cars included Jacques Villeneuve, who won the Indianapolis 500 and the CART championship in 1995; and Dan Wheldon (co-major sponsor with Jim Beam) as well as being an associate sponsor for all of Andretti-Green Racing, who won the Indianapolis 500 in 2005.
The position of the lenses A and B are known, and the angle of the lenses α and/or β is set by the operator so that both are aimed at the target. Because the distance between A and B on a coincidence rangefinder is typically fixed, once the angle is set correctly the operator need only read the range from the scale.
This means that, for a triangle with a given angle, the ratio of opposite side length to adjacent side length (tangent [broken anchor]) is constant. By using a reticle with marks of a known angular spacing, the principle of similar triangles can be used to find either the distance to objects of known size or the size of objects at a known ...
An angle gauge is a tool used by foresters to determine which trees to measure when using a variable radius plot design in forest inventory. Using this tool a forester can quickly measure the trees that are in or out of the plot. An angle gauge is similar to a wedge prism though it must be held a fixed distance from the eye to work properly ...
The pilot may use this pointer to home directly towards the beacon, or may also use the magnetic compass and calculate the direction from the beacon (the radial) at which their aircraft is located. Unlike the RDF, the ADF operates without direct intervention, and continuously displays the direction of the tuned beacon.
Many indicators have a mounting lug with a hole for a bolt as part of the back plate. Alternatively, the device can be held by the cylindrical stem that guides the plunger using a collet or special clamp, which is the method generally used by tools designed to integrate an indicator as a primary component, such as thickness gauges and comparators.
