Linear induction motor
A linear induction motor is an electric machine producing thrust directly along a straight path, like a rotary induction motor unrolled flat, used in urban metros and low-speed maglev.
Linear interpolation
Linear interpolation is a method of estimating a function's value between two known data points by following the straight line joining them, the simplest and most widely used interpolation method.
Linear inverted pendulum model
The linear inverted pendulum model is a simplified model for humanoid bipedal walking, introduced by Shuuji Kajita and Kazuo Tani in 1991 and extended to three dimensions in 2001.
Linear low-density polyethylene
Linear low-density polyethylene (LLDPE) is a semicrystalline polyethylene copolymer in which ethylene is polymerized with an alpha-olefin such as 1-butene, widely used in stretch film and food packaging.
Linear matrix inequality
A linear matrix inequality (LMI) is a convex constraint requiring an affine matrix expression to be positive definite, central to control theory since Lyapunov's 1890 stability criterion.
Linear motion guide carriage
The linear motion guide carriage, also called an LM block, is the moving block of a linear guide, riding a profiled rail on recirculating balls while carrying loads.
Linear motor
A linear motor, also called a linear electric motor, is an electric motor producing thrust in a straight line directly, used in precision stages and maglev trains.
Linear parameter-varying model
A linear parameter-varying (LPV) model is a linear state-space model whose matrices vary with a measured scheduling signal, used to design gain-scheduled controllers with stability guarantees.
Linear pendant
A linear pendant is a long, horizontally elongated light fixture suspended from the ceiling by cables or stems, hung parallel to kitchen islands, dining tables, or bars.
Linear Pluggable Optics
Linear Pluggable Optics (LPO) is an optical transceiver architecture for short-reach data center links in which the pluggable module contains no DSP, reducing power, cost, and latency in AI clusters.
Linear polarization resistance
Linear polarization resistance is an electrochemical technique that measures a metal's instantaneous corrosion rate from its current response to a small potential, widely used on rebar in concrete.
Linear positioning stage
A linear positioning stage is a precision mechanical device that moves a load along a single straight axis, using a guided carriage, a screw or motor drive, and position feedback.
Linear prediction
Linear prediction is a signal-processing method that estimates a signal's next sample from a weighted combination of past samples, and is the dominant technique for modeling speech spectra.
Linear predictive coding
Linear predictive coding (LPC) is a signal processing method that compresses speech by predicting each sample from earlier samples and transmitting only the coefficients and a small residual.
Linear probing
Linear probing is a collision-resolution scheme for open-addressing hash tables that places a colliding key in the next free slot; introduced in 1954, it remains among the fastest hash tables in practice.
Linear programming
Linear programming, also called linear optimization, is a method for optimizing a linear objective function subject to linear constraints, formulated by George Dantzig in 1947.
Linear quadratic Gaussian control
Linear quadratic Gaussian (LQG) control is an optimal control method that combines the linear quadratic regulator with a Kalman filter to control linear systems affected by Gaussian noise.
Linear receive optics
Linear Receive Optics (LRO), also called half-retimed optics or HALO, is a transceiver architecture for high-speed data center links that keeps a DSP on the transmit path only.
Linear scale (glass scale encoder)
A glass scale linear encoder is an optical position sensor that reads a graduated glass strip, giving micron-level feedback on CNC machines and measuring equipment.
Linear search
Linear search is an algorithm that finds a target value in a list by checking each element in order until it finds a match or reaches the end.
Linear synchronous motor
A linear synchronous motor (LSM) is an electric machine producing straight-line motion by locking the mover to a traveling magnetic field, used in maglev trains and factory automation.
Linear Tape-Open
Linear Tape-Open, known as LTO or LTO Ultrium, is an open-format magnetic tape storage standard developed by HPE, IBM, and Quantum for enterprise backup and archiving, now in its 10th generation.
Linear temporal logic planning
Linear temporal logic planning is a method of robot control in which a task written as a linear temporal logic formula is synthesized into a plan guaranteed to satisfy it.
Linear type
A linear type is a type whose values must be used exactly once, derived from Girard's 1987 linear logic and used to track resources like file handles.
Linear variable differential transformer
A linear variable differential transformer, or LVDT, is an inductive transducer that measures linear displacement, popularized by Herman Schaevitz in 1946 and widely used in aerospace and industry.
Linear-feedback shift register
A linear-feedback shift register is a digital circuit whose XOR feedback generates long repeating bit sequences that look random, used in stream ciphers and hardware testing.
Linear–quadratic regulator
The linear–quadratic regulator (LQR) is an optimal feedback controller for linear systems, computing a state-feedback law that drives the state toward zero while penalizing control effort.
Linearizability
Linearizability is a correctness condition for concurrent objects under which each operation appears to take effect exactly once between its invocation and response, defined by Maurice Herlihy and Jeannette Wing in 1990.
Linearly constrained minimum variance beamformer
The linearly constrained minimum variance (LCMV) beamformer, also called Capon's method, is an adaptive spatial filter for sensor arrays used in radar, sonar, and medical imaging.
Linearly constrained minimum variance beamforming
Linearly constrained minimum variance (LCMV) beamforming is an adaptive sensor array technique, introduced by O. L. Frost III in 1972, that minimizes output noise and interference while preserving unity gain toward a desired direction.
