Abstract: A drapery holdback assembly having interchangeable, adjustable decorative ends is provided. The drapery holdback includes a base portion for mounting to a supporting surface. A neck portion extends from the base portion to a distal head portion, which provides an arcuate magnet along a portion of its periphery. The drapery holdback includes an interface assembly having a decorative end and an opposing joint end, wherein the joint end forms a magnetically attractive curved surface so as to be movable and/or positionable over the arcuate magnet to various orientations. Being magnetically connected, different interface assemblies and so different decorative ends, may be interchanged onto the head portion at the user's whim. A spring is disposed between the decorative and joint ends, so that the interface assembly absorbs shock and other compressive forces to prevent damage to the drapery holdback assembly.

Abstract: An uninterruptible power supply (UPS) system includes at least two UPS modules having respective switchmode power converter circuits coupled in common to a current source/sink by respective conductors. The system further includes at least one differential mode inductor magnetically coupling the at least two conductors. For example, the switchmode power converter circuits may include respective DC/DC converter circuits coupled in common to a terminal of a DC power source, such as a battery, by the conductors. The differential mode inductors may be implemented using, for example, ferrite rings.
