(aerospace engineering)
The process in which a missile is taken under control by the guidance system.
(astrophysics)
Of a central force field, as of a planet, to overcome by gravitational force the velocity of a passing body and bring the body under the control of the central force field, in some cases absorbing its mass.
(geochemistry)
In a crystal structure, the substitution of a trace element for a lower-valence common element.
(hydrology)
The natural diversion of the headwaters of one stream into the channel of another stream having greater erosional activity and flowing at a lower level. Also known as piracy; river capture; river piracy; robbery; stream capture; stream piracy; stream robbery.
(physics)

i. In flying aircraft, to control aircraft trajectory to intercept and then follow an external radio beam (as in ILS, or instrument landing system).
ii. To detect and lock onto a target by a radar.
iii. In flying, to reach a desired altitude or direction, especially using an autopilot or automatic flight control system.

The proposed methods allowed successful atrial capture in all patients with whom the standard bipolar transesophageal method was successful.
The Adapta, Versa and Sensia pacemakers are completely automatic, and include the Medtronic-exclusive feature Atrial Capture Management (ACM).
Now, physicians can use the device with a pioneering feature called Atrial Capture Management (ACM), which enables the pacemaker to automatically adjust electrical impulses delivered to the heart's upper right chamber (atrium).
