• G01P 3/04 by comparing two speeds
• G01P 3/10 by actuating an indicating element, e.g. pointer, for a fixed time
• G01P 3/12 by making use of a system excited by impact
• G01P 3/14 by exciting one or more mechanical resonance systems
• G01P 3/16 by using centrifugal forces of solid masses
• G01P 3/24 by using friction effects (G01P3/06 takes precedence)
