Another type of finder commonly found on amateur telescopes is known as a reflector (reflex) sight. This non-magnifying sight (technically not a "scope") uses a type of beam splitter to "reflect" a reticle generated by collimating optics into the users field of view.
The Portuguese copulas are ser and estar. As in Spanish, estar derived from Latin sto / stare: stare → *estare → estar. The copula ser developed both from svm and sedeo. Thus its inflectional paradigm is a combination of these two Latin verbs: most tenses derive from svm and a few from sedeo. E.g. derivation from sedeo: [1] sedere → seer ...
A reflex finder is a viewfinder system with a mirror placed behind a lens. The light passing through the lens is reflected by the mirror to a focusing screen , usually ground glass . The image formed on this ground glass can be observed directly, giving a waist-level reflex finder, or through a redressing optical device (set of mirrors or prism ...
ABBYY FineReader PDF is an optical character recognition (OCR) application developed by ABBYY. [ 2 ] [ 3 ] First released in 1993, the program runs on Microsoft Windows ( Windows 7 or later) and Apple macOS (10.12 Sierra or later).
A height finder radar is a type of 2-dimensional radar that measures altitude of a target. The operator slews the antenna toward a desired bearing , identifies a target echo at a desired range on the range height indicator display, then bisects the target with a cursor that is scaled to indicate the approximate altitude of the target.

Library clients can use pathfinders at their own pace, and may find them "more approachable" than a reference desk. Electronic pathfinders on a library website can be used 24 hours a day. [ 20 ] In higher education, embedding library subject guides into a learning management system has been shown to increase use of library resources among ...
Feature-based retrieval models view documents as vectors of values of feature functions (or just features) and seek the best way to combine these features into a single relevance score, typically by learning to rank methods. Feature functions are arbitrary functions of document and query, and as such can easily incorporate almost any other ...
Interior of a sound-based key finder. Early models of key finder were sound-based, and listened for a clap or whistle (or a sequence of same), then beeped for the user to find them. Determining what was a clap or a whistle proved difficult, resulting in poor performance and false alarms.
