Three fundamental elements of LCA, the Mechanism, the Actuator, and the Controller are explained in this section. Firstly, definitions of the three elements are discussed.

Definitions of the fundamental LCA elements

Mechanism

Construction elements that generate added value such as process/assemble by taking inputs from actuator and controller/sensor.

Actuator

Construction elements that extract mechanical energy as outputs from non-mechanical energy inputs.

Controller

Construction elements that generate non-mechanical energy as outputs from input signals.

Sensor

Construction elements that generate signal outputs from physical phenomena inputs.
