Abstract: An apparatus, system, and method are disclosed for combining multiple windings on a magnetic core. An integrated winding structure has a winding base and multiple winding extensions. The multiple winding extensions and the winding base are formed from a single sheet of electrically conductive material. Each of the multiple winding extensions has a base portion that extends from the winding base, a wrapping portion that extends from the base portion, and a connection portion that extends from the wrapping portion. The connection portions and the winding base each have electrical connection surfaces. Each of the multiple winding extensions forms one or more windings on the magnetic core.

Abstract: An apparatus, system, and method are disclosed for a low cost self-healing power supply. The invention includes a power supply that regulates a direct current (“DC”) regulated bus to maintain a regulated bus voltage under varying load conditions. The power supply includes at least one pulse-width modulated stage, wherein each pulse-width modulated stage includes at least two switches connected in parallel. Each switch includes a fuse connected in series with the switch that disconnects the switch in response to an over current condition sufficient to open the fuse. The power supply also includes a pulse-width modulator for each stage of the power supply that regulates a bus voltage controlled by the stage by sensing the controlled bus voltage and adjusting a switching duty cycle to regulate the controlled bus voltage to a target value. The pulse-width modulator for a stage provides a substantially identical switching duty cycle to each switch of the stage.

Abstract: An apparatus, system, and method are disclosed for a low cost multiple output redundant power supply. Disclosed is a power supply that includes a primary stage for regulating voltage on an internal bus. The power supply includes a first regulator stage and a second regulator stage connected to the internal bus. The first regulator stage regulates voltage on a bus configured to connect to a first system. The second regulator stage regulates voltage on a bus configured to connect to a second system. The each regulator stage continues to operate in the event the other regulator stage is not operating. A disconnecting means is connected between the primary stage and the each regulator stage for isolating the failed regulator stage from the other regulator stage and the primary stage.

Abstract: The present invention provides new systems and strategies for the regulation of iron metabolism in mammals. In particular, methods of using agonists and antagonists of TGF-? superfamily members to modulate the expression or activity of hepcidin, a key regulator of iron metabolism, are described. The inventive methods find applications in the treatment of diseases associated with iron overload, such as juvenile hemochromatosis and adult hemochromatosis, and in the treatment of diseases associated with iron deficiency, such as anemia of chronic disease and EPO resistant anemia in end-stage of renal disease. The present invention also relates to screening tools and methods for the development of novel drugs and therapies for treating iron metabolism disorders.

Abstract: Particles, preferably toner particles comprised of at least binder and colorant, are described that include a doped conductive polymer material as a surface additive on the external surface of the particle. The presence of the doped external conductive polymer material enables the particles to retain a substantially uniform charge distribution over the surface of the particles over time, and also enables appropriate control over the triboelectric (tribo) properties of a developer. Also described are developers comprised of such particles in admixture with carrier particles, and methods of making the particles and developers.
