Industrial Minera México
Industrial Minera México (IMMSA) is a Mexican underground mining company, descended from Asarco's Mexican operations dating to 1890, that produces zinc, lead, copper, silver, and gold at mines including Charcas and Santa Bárbara.
Industrial process control
Industrial process control is the engineering discipline behind stable operation in the process industries, built on PID control loops, control strategies like cascade and feedforward, and distributed control systems.
Industrial processes
Industrial processes are systematic mechanical, thermal, or chemical operations that convert raw materials into finished products, ranging from casting, machining, and welding to petroleum refining and cement manufacture.
Industrial robot
An industrial robot is a reprogrammable, multipurpose manipulator programmable in three or more axes, fixed or mobile, used for accurate repetitive factory work such as welding and assembly.
Industrial symbiosis
Industrial symbiosis is the exchange of materials, energy, and by-products between separate industries so that one company's waste becomes another's input, as at Kalundborg, Denmark.
Industrial Technology Research Institute (工业技术研究院)
Industrial Technology Research Institute (ITRI; 工業技術研究院) is Taiwan's government-supported applied research institute, founded in 1973, which introduced integrated circuit technology to Taiwan and spun off TSMC and UMC.
Industrial waste
Industrial waste, also called manufacturing waste, is discarded solid, liquid, or gaseous material produced by manufacturing, mining, construction, and energy production, distinct from household waste.
Industrial wastewater treatment
Industrial wastewater treatment, or an effluent treatment plant, is the physical, chemical, and biological treatment of water from industrial facilities, treated on site or at municipal plants.
Industrialization of Bohemia
The industrialization of Bohemia turned the Bohemian Lands, with Moravia and Austrian Silesia, into the most industrially advanced region of the Habsburg Monarchy by the late nineteenth century.
Industry Foundation Classes
Industry Foundation Classes (IFC) is an open data model describing objects, properties, and relationships in buildings and infrastructure, published by buildingSMART International as ISO 16739.
Industry Standard Architecture
Industry Standard Architecture (ISA), or AT bus, is the expansion-bus standard of IBM PC compatible computers from the early 1980s into the 2000s, beginning as the 8-bit PC bus.
Ineffable Intelligence
Ineffable Intelligence is a British AI research company in London, founded by DeepMind veteran David Silver in 2025 to build systems that learn from experience.
INEOS FPS
INEOS FPS is the INEOS-owned company that operates the Forties Pipeline System, which transports North Sea oil and gas liquids to the Kinneil Terminal at Grangemouth, Scotland.
Ineos Fusilier
The Ineos Fusilier is a four-wheel-drive electric SUV announced by Ineos Automotive in 2024, planned with battery-electric and range-extender powertrains but paused in July 2024.
Ineos Grenadier
The Ineos Grenadier is a four-wheel-drive off-road vehicle produced by INEOS Automotive since 2022, conceived by Jim Ratcliffe as a successor in spirit to the original Land Rover Defender.
Inert anode aluminium smelting
Inert anode aluminium smelting is a variant of the Hall-Héroult process in which non-consumable anodes release oxygen, eliminating direct carbon dioxide emissions from aluminum production.
Inert gas welding
Inert gas welding, covering TIG and MIG, joins metals by melting them with an electric arc shielded by inert argon or helium gas, preventing porous, weak welds.
Inert matrix fuel
Inert matrix fuel (IMF) is a uranium-free nuclear fuel that embeds plutonium in an inert matrix such as stabilized zirconia, burning it without breeding new plutonium.
Inertia constant
The inertia constant (H) measures the kinetic energy stored in a synchronous generator's rotating mass, expressed in seconds, and governs how fast grid frequency changes.
Inertia operation
Inertia operation is a semi-automatic firearm operating principle, used chiefly in shotguns, in which recoil energy cycles the action through a spring-loaded, two-piece bolt instead of gas.
Inertial confinement fusion
Inertial confinement fusion (ICF), also called laser fusion, compresses small fuel capsules with intense driver energy so the fuel fuses briefly; the NIF first achieved ignition in 2022.
Inertial electrostatic confinement
Inertial electrostatic confinement (IEC), developed by Philo Farnsworth and Robert Hirsch in the 1960s, is a fusion scheme using electrostatic potential wells, used mainly as a compact neutron source.
Inertial measurement unit
An inertial measurement unit (IMU) is an electronic device that measures specific force and angular rate in six degrees of freedom, serving as the sensing front end of inertial navigation systems.
Inertial measurement unit preintegration
Inertial measurement unit (IMU) preintegration summarizes hundreds of high-rate accelerometer and gyroscope readings between camera keyframes into a single relative motion constraint for visual-inertial odometry.
Inertial navigation system
An inertial navigation system, or inertial guidance system, is a self-contained device that computes a vehicle's position, velocity, and orientation using accelerometers and gyroscopes, without external references such as GPS.
Inertial odometry
Inertial odometry is a dead-reckoning method that estimates a vehicle's or person's position, velocity, and orientation by integrating accelerometer and gyroscope measurements alone, without satellite signals, maps, or cameras.
Inertial Upper Stage
The Inertial Upper Stage (IUS) is a two-stage, solid-fuel booster developed by the US Air Force and NASA, flown with the Space Shuttle and Titan rockets from 1982 to 2004.
Infantas Oil and Gas Field
The Infantas Oil and Gas Field is an oil field near Barrancabermeja, Colombia, whose 1918 discovery well began the Colombian oil industry; Ecopetrol has operated it since 1951.
Infantry fighting vehicle
An infantry fighting vehicle (IFV), also called an infantry combat vehicle, is an armored combat vehicle that carries an infantry squad and is armed with a cannon of at least 20 mm.
Infantry tank
The infantry tank was a class of heavily armored, deliberately slow tank defined by British interwar doctrine, meant to advance with walking infantry; examples include the Matilda, Valentine, and Churchill.
