The camera's internal exposure timing mechanism disengages below the 1/2 second setting.

Species that move short distances, however, may not need such a timing mechanism, instead moving in response to local weather conditions.

Meters were soon relocated inside the taxi, and in the 1980s electronic meters were introduced, doing away with the once-familiar ticking sound of the meter's timing mechanism.

As a timing mechanism, detonation cord detonates at a very reliable rate (about 7,0008,000 m/s), enabling engineers to control the pattern in which charges are detonated.

Because of this the timing mechanism became inaccurate and just when the explosives attached to the ship blew, a tugboat came by and managed to haul the wreck to land.
