  2. Limit switch - Wikipedia

    en.wikipedia.org/wiki/Limit_switch

    In electrical engineering, a limit switch is a switch operated by the motion of a machine part or the presence of an object. A limit switch can be used for controlling machinery as part of a control system , as a safety interlock , or as a counter enumerating objects passing a point.

  3. LA-2A Leveling Amplifier - Wikipedia

    en.wikipedia.org/wiki/LA-2A_Leveling_Amplifier

    The LA-2A has simple controls: a Peak-Reduction knob controls the gain of the side-chain circuit, and therefore, the gain reduction; a Gain Control for make-up gain; and a Limit/Compress switch which alters the compression ratio. The VU meter may also be switched to show the gain reduction or output level.

  4. Pilot wave theory - Wikipedia

    en.wikipedia.org/wiki/Pilot_wave_theory

    Louis de Broglie's early results on the pilot wave theory were presented in his thesis (1924) in the context of atomic orbitals where the waves are stationary.Early attempts to develop a general formulation for the dynamics of these guiding waves in terms of a relativistic wave equation were unsuccessful until in 1926 Schrödinger developed his non-relativistic wave equation.

    A right-hand railroad switch with point indicator pointing to right Animated diagram of a right-hand railroad switch. Rail track A divides into two: track B (the straight track) and track C (the diverging track); note that the green line represents direction of travel only, the black lines represent fixed portions of track, and the red lines depict the moving components.

    Wholeness and the Implicate Order is a book by theoretical physicist David Bohm.It was originally published in 1980 by Routledge, United Kingdom.. The book is considered a basic reference for Bohm's concepts of undivided wholeness and of implicate and explicate orders, as well as of Bohm's rheomode - an experimental language based on verbs.

  7. Aharonov–Bohm effect - Wikipedia

    en.wikipedia.org/wiki/Aharonov–Bohm_effect

    It is generally argued that the Aharonov–Bohm effect illustrates the physicality of electromagnetic potentials, Φ and A, in quantum mechanics.Classically it was possible to argue that only the electromagnetic fields are physical, while the electromagnetic potentials are purely mathematical constructs, that due to gauge freedom are not even unique for a given electromagnetic field.

    en.wikipedia.org/wiki/Miniature_snap-action_switch

    In 1937 W.B. Schulte, [2] McGall's employer, started the company MICRO SWITCH. The company and the Micro Switch trademark have been owned by Honeywell Sensing and Control since 1950. [3] The name has become a generic trademark for any snap-action switch. Companies other than Honeywell now manufacture miniature snap-action switches.
