  2. Slot-die coating - Wikipedia

    en.wikipedia.org/wiki/Slot-die_coating

    Both industrial roll-to-roll and sheet-to-sheet systems typically feature slot-dies in the range of 300 to 1000 mm in coating width, though slot-dies up to 4000 mm wide have been reported. Commercial slot-die systems are claimed to operate at speeds up to several hundred square meters per minute, [ 14 ] with roll-to-roll systems typically ...

    Inorganic LED - Flexible LED is commonly made into 25, 50, 100 m, or even longer strips using a roll-to-roll process. A long neon LED tube is using such a long flexible strip and encapsulated with PVC or silicone diffusing encapsulation. Organic LED (OLED) - OLED for foldable phone screen is adopting roll-to-roll processing technology.

    en.wikipedia.org/wiki/Engineering_design_process

    The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.

  6. Engineering change order - Wikipedia

    en.wikipedia.org/wiki/Engineering_Change_Order

    An engineering change order (ECO), also called an engineering change notice (ECN), engineering change (EC), or engineering release notice(ERN), is an artifact used to implement changes to components or end products. The ECO is utilized to control and coordinate changes to product designs that evolve over time.

  7. Earthworks (engineering) - Wikipedia

    en.wikipedia.org/wiki/Earthworks_(engineering)

    In military engineering, earthworks are, more specifically, types of fortifications constructed from soil. Although soil is not very strong, it is cheap enough that huge quantities can be used, generating formidable structures. Examples of older earthwork fortifications include moats, sod walls, motte-and-bailey castles, and hill forts.

    en.wikipedia.org/wiki/Web-guiding_systems

    Active guiding systems are composed of a sensor, an actuator connected to a guide mechanism, and a controller. [2] The sensor can be any detector, which can reliably pick up the edges of a web. The most common types of sensors are pneumatic (only works with nonporous webs), optical (works well with opaque webs), ultrasonic (works with most ...
