31Oil and gas industry metering and control system — Remote gas well sites require local flow metering of the mineral reserve s gas flow rate for asset and revenue accounting purposes. Differential pressure flow meters are commonly used for this purpose.[1] Traditionally, local flow metering was… …
32Control of the National Grid — The National Grid is the high voltage electric power transmission network in Great Britain, connecting power stations and major substations, and has a synchronized organization such that electricity generated anywhere in Great Britain can be used …
33Control line — Brodak Control Line Aerobatic Strega in flight Control line (also called U Control ) is a simple and light way of controlling a flying model aircraft. The aircraft is connected to the operator by a pair of lines, attached to a handle, that work… …
34Control of the National Grid (UK) — The National Grid (UK) is the high voltage electric power transmission network in Great Britain, connecting power stations and major substations to ensure that electricity generated anywhere in Great Britain can be used to satisfy demand… …
35Power factor — For other uses, see Power factor (pistol). The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load over the apparent power in the circuit,[1][2] and is a dimensionless number between 0 and 1… …
36Control theory — For control theory in psychology and sociology, see control theory (sociology) and Perceptual Control Theory. The concept of the feedback loop to control the dynamic behavior of the system: this is negative feedback, because the sensed value is… …
37Power door locks — Animation of how power lock system works (simple relay operation) Power door locks (also known as electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck …
38control theory — Field of applied mathematics relevant to the control of certain physical processes and systems. It became a field in its own right in the late 1950s and early 60s. After World War II, problems arising in engineering and economics were recognized… …
39Control channel — In radio communication, a control channel is a central channel that controls other constituent radios by handling data streams. It is most often used in the context of a trunked radio system, where the control channel sends data which coordinates …
40Control moment gyroscope — A control momentum gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum. As the rotor… …
