The SMART Coupler consists of a specially designed broadband, passive, directional coupler for 130 -- 960 MHz combined with active, diagnostic tools for system monitoring with failure detection and isolation capabilities.
The MAG Coupler is devilishly simple in concept, but ingenious in application.
The Bobcat Hydraulic Coupler is available both as a factory installed option and as an aftermarket product for use with all the pin-on fitting attachments for the E25 to E55 excavators.

Standard operation requires the operator to curl the attachment, generating a pressure signal that opens the quick coupler's locking system.
According to the contract, CPI's Beverly Microwave Division will offer an initial quantity of power couplers to the European XFEL over a 12-month period, with the potential for additional power couplers at a later date.
Here in this study, we take advantage of the bared core of the fibers to develop coupler using lapping technique with other enforcement such as force and different bending angles to display various coupler/splitter characterizations depending on the customers' needs [5].
The grating couplers were designed for an FBG demodulation system that was fabricated on a standard SOI wafer with a top silicon thickness ([d.sub.si]) of 0.22 [micro]m and a buried oxide thickness ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]) of 2 [micro]m.
A recent inspection found too much corrosion around the upper coupler plate and frame structure.
The CRLH approach of left-handed (LH) structures, in which phase and group velocities exhibit opposite signs and correspond to negative refractive index materials, was recently proposed and demonstrated to provide an efficient tool for the design of novel structures and devices, such as couplers [1-3], band pass filters [4-6], antennas [7-9], and multi-frequency devices [10,11].
Therefore, the branch-line couplers as the key components of it and several functions are required simultaneously, such as dual-band operation, arbitrary coupling levels, and inherent impedance transforming.
Hybrid 90[degrees] couplers are key components to divide or combine signals with a proper phase difference which are widely implemented in radio frequency (RF) devices, such as power amplifiers, mixers, and antenna systems [1-4].
