Abstract: A negative pressure wound dressing for use with breast incisions. The wound dressing includes a drape layer, a manifold layer, a base layer, and a reduced pressure interface. The drape layer has a first surface and a second, wound-facing, surface. The drape layer is substantially impermeable to liquid and substantially permeable to vapor. The manifold layer has a first surface and a second, wound-facing surface. The manifold layer has a perimeter defined by a first convex curved side surface defining a first lobe, a second convex curved side surface defining a second lobe, and a connecting portion between the first lobe and the second lobe. The base layer is configured to: (i) couple the drape layer to the manifold layer, and (ii) the dressing to a patient's tissue. The reduced pressure interface is integrated with the drape layer.

Abstract: There is disclosed a method and apparatus for communicating in multi- and single story building structures and parts thereof wherein a signal voltage source is connected to a metallic building structural member which is an integral part of the building. Multi-story buildings at least as high as fifty stories have been excited by utilizing a structural member such as a vertically extending stand pipe and like structural members. In such multi-story structures and in smaller structures such as one story frame, masonry and metal building structures, one of the terminals from the voltage source may be connected to earth ground by stakes or rods driven in the ground. Resistance means are inserted in the lines to limit the short circuit current and to provide a degree of impedance match.
