Vacuum gauge - A vacuum gauge is used to measure the pressure in a vacuum, which is broadly divided into two categories: high and low vacuum (and sometimes ultra-high vacuum). Many of the different techniques used to measure these categories have an overlap at some point ...
Ionization gauge - An ionization gauge, or ion gauge, is a vacuum gauge that is used to measure the residual pressure of vacuum in the high vacuum and ultra-high vacuum (UHV) ranges. There are two main types of ionization gauges, called the hot cathode and cold cathode types.
Vacuum angle - In quantum gauge theories, in the Hamiltonian formulation, the wave function is a functional of the gauge connection A and matter fields φ. Being a quantum gauge theory, we have to impose first class constraints in the form of functional differential equations.
Vacuum brake - The vacuum brake is a braking system used on trains. It was first introduced in the mid 1860s but the most widely adopted system was invented in 1877 in the USA, where it enjoyed only a brief period of popularity, primarily on narrow gauge railroads.

Submissions welcome. www.moregeneralcontractors.com QCD vacuum - The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non-perturbative vacuum state, characterized by many non-vanishing condensates such as the gluon condensate or the quark condensate. Vacuum arc - A vacuum arc ...
Electronic Display - ... An Electronic Flight Information System (EFIS) is a type of electronic display (usually a CRT or LCD) fitted to the cockpit of an aircraft in order to display flight information. EFIS is more modern, more efficient, and easier to understand than the gauges that traditionally display information in older cockpits. Seven-segment display - A seven-segment display (sometimes written as 7-segment display) is a form of display that predates the now ubiquitous dot-matrix displays. Seven segment displays are commonly used in electronics as a method of displaying decimal numeric feedback on the internal operations of devices. Vacuum fluorescent display - A vacuum fluorescent display (VFD) is a type of display used primarily on consumer-electronics equipment such as video cassette recorders. Unlike liquid crystal displays, a VFD emits a very bright light with clear contrast. Electronic Display Measurement: Concepts, ...
