1. A feedback system that consists of a sensing element, amplifier, and servomotor, used in the automatic control of a mechanical device.
2. A self-regulating feedback system or mechanism: "We do not need to know in detail how the minute chemical servomechanisms of the muscles operate in order to move our arms" (Harper's).

In the author's conjectural view, a sort of servomechanism entered into play, and enabled him to "come to himself." He experienced an "aha" moment in space and time.
On the other end, connected to the servomotor is the mechanical system that the servomotor moves--the servomechanism. Commonly this mechanism is a simple linear actuator that translates the rotary motion to linear using a screw or belt, but the mechanisms used in industry can be complex and diverse, depending on the job that has to be done--and the imagination and expertise of the machine builder.
The dc output of the InGaAs photodiode was kept constant by a servomechanism of variable neutral density filter.

(36.) It reads that the universe performs as the (mindful) intentional servomechanism which is immensely unified, yet at the same time infinitely diverse.

These results led to development of a uterine servomechanism model indicating that PRL binds to its receptor and increases expression of PGR which then allow P4 to stimulate secretion of uteroglobin and PRL also acts to increase numbers of PRL receptors (Chilton et al., 1988).

In particular, two different controller designs were obtained, considering the system as a linear, constrained, robust servomechanism problem (LCRSP) (Davison and Ferguson 1981) and as a nonlinear, constrained, servomechanism problem (NCSP) (Davison 1976).
If a bureaucracy is a servomechanism, its ability to process an error signal, and so generate corrective commands and drive the system away from error, is a function of the depth of the hierarchy.
