Self-limiting (biology)
In biology, a self-limiting organism or colony of organisms limits its own growth by its actions. For example, a single organism may have a maximum size determined by genetics, or a colony of organisms may release waste which is ultimately toxic to the colony once it exceeds a certain population. In some cases, the self-limiting nature of a colony may be advantageous to the continued survival of the colony, such as in the case of parasites. If their numbers became too high, they would kill the host, and thus themselves. In other cases, self-limitation restricts the viability of predators, thus ensuring the long-term survival of rare species.

Governor (device)
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow of steam. History Centrifugal governors were used to regulate the distance and pressure between millstones in windmills since the 17th century. Early steam engines employed a purely reciprocating motion, and were used for pumping water – an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the ''rotative'' steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton, produced some 500 ...

Electronic Speed Limiter
A speed limiter is a governor used to limit the top speed of a vehicle. For some classes of vehicles and in some jurisdictions they are a statutory requirement, for some other vehicles the manufacturer provides a non-statutory system which may be fixed or programmable by the driver. Statutory (UK) Mopeds The legal definition of a moped in the United Kingdom was revised in 1977 to include a maximum design speed of 30 mph (48 km/h). This was further revised to 50 km/h (31 mph) in the 1990s, then 45 km/h (28 mph) in the late 2000s to fall in line with unified European Union licensing regulations. Department for Transport (2008), p.179 "Mopeds redefined to 30 mph maximum design speed" To comply with this, mopeds typically include some method of onboard speed restriction to prevent the machine exceeding the prescribed speed (on a flat road, in still air, with a rider of standard height and weight). Older models such as the Honda C50 used a simple centri ...
