Binary adders are digital devices that are capable of adding binary numbers. There are two basic types: half-adders and full-adders

Gradient index (GRIN) lenses focus light through a precisely controlled radial variation of the lens material's index of refraction from the optical axis to the edge of the lens.

Hot stamps, metal stamps, and type are used to leave an impression on a target object. Rubber stamps are used to mark items with ink.

English roller chain sprockets engage chains in many different power transmission and conveyor systems. Sprockets and chains are often an economic, reliable drive system for long running, continuous drive applications with limited shock and torque loads. English sprockets are classified according to ANSI number designations
