Because IRIS is an ultrasonic technique, it requires a couplant.

Preferably, the taut fabric sheet is substantially porous with respect to an acoustic couplant.

A porous membrane (83) and an ultrasound probe (80) cooperate to define a chamber (90) which contains a liquid acoustical couplant.

The diplexer has a first filter coupling the first port to the second port and a second filter coupling the first port to the third port.

The rotary power tool also includes an upper joint coupling the upper portion of the handle to the housing and a lower joint coupling the lower portion of the handle to the housing.

The feed structure includes a dielectric tube, a first connector coupling the RF transmission line to the first tubular conductor, and a second connector coupling the RF transmission line to the second tubular conductor.

The DC/DC converter includes a transformer coupling a high side to a low side.

A fuse circuit is provided with a fuse coupling a first node and a second node, a latch circuit and a diode coupling the second node and an input end of the latch circuit.

A pivoting connector (10) couples a vertebral member to a longitudinal member (28).

A annular spring is formed by coupling column type spool spring.

The compounds are prepared by coupling an aminoalkylphenyl-sulfonamide with an appropriately substituted epoxide.

A configurable interface system (100) couples an accessory (102) to a communication device (104).

The legs are interconnected by a plurality of struts (52, 54, 56, 58, 60, 62).

A switch hook interface circuit couples a subscriber telephone to a subscriber telephone line.

The switching node includes a first switch coupling the respective input waveguide to an intermediate waveguide and a second switch coupling the intermediate waveguide to the respective output waveguide.
