Diodes application in mechanical engineering

[jpc08]

can anyone give me some suggestions on the applications of diodes to our course?
i'm not really familiar with machines that uses diodes.
a simple example would be enough and highly appreciated.
i'm just a 2nd year college student by the way.

Almost any modern piece of electronics uses diodes.

Diodes are an electronic component and therefore used in electrical engineering, not mechanical engineering.

Well, diodes are used in the automotive industry to rectify (turn AC into DC) the output of alternators.

Motor technology is largely mech eng.
