direct coupling

[də¦rekt ′kəp·liŋ]
(electricity)
Coupling of two circuits by means of a non-frequency-sensitive device, such as a wire, resistor, or battery, so both direct and alternating current can flow through the coupling path.
(mechanical engineering)
The direct connection of the shaft of a prime mover (such as a motor) to the shaft of a rotating mechanism (such as a pump or compressor).

Direct coupling can be used to great effect (this is the "buzz me" technique when, for example, a vessel is grasped with a tissue forceps and then coagulated by touching the forceps with an activated electrode), but when it happens unintentionally, the result maybe catastrophic.
Although these approaches can be quite useful in addressing many engineering problems, they mostly correspond to standard direct coupling methodologies and thus exhibit well-known limitations.
Permanent magnet generators became popular because they eliminate field windings and enable direct coupling of wind turbines [6].
In some antennas [3, 4], special shaped slots are designed between the orthogonal feed lines and the radiation patch to guarantee the dual-polarization, while direct coupling feed to the patch can also achieve good performance [6].
The Holey Optochips are designed for direct coupling to a standard 48-channel multimode fiber array through an efficient microlens optical system that can be assembled with conventional high-volume packaging tools.
When dealing with 60 Hz noise, there is magnetic coupling and direct coupling, so in this instance, the focus is on the two coupling mechanisms.
"This direct coupling of excitons to photons allows us to link computation and communication," he added.
Each channel provides a dual redundant 1553 interface and is transformer coupled although direct coupling is optional.
There are several sources or "entries" for unwanted coupling: the most obvious path is direct coupling in the form of inductive and capacitive coupling between signal conductors.
Dassault Systcmes have announced the availability of a new SIMULIA direct coupling interface that allows third-party physics codes developed by partners or customers to communicate directly with its Abaqus FEA software for high-performance multiphysics simulation.
A highly efficient direct coupling of iodole compounds with 1,4-benzoquinones was developed "on water" in the absence of any catalyst via CDC.
The term "direct drive" describes the direct coupling of the buoy's velocity and force to the generator without the use of hydraulic fluid or air.
