摘要： Matrix filters useful in low-noise power distribution systems include arrays of capacitors and inductors with interleaved interconnections in an high density interconnect structure so as to achieve nearly ideal performance, i.e., such that capacitor and inductor parasitics are minimized. The matrix filters are bi-directional which help to isolate different load modules by attenuating the switching noise of associated power converters as well as the noise generated by digital loads.

摘要： An uninterruptible power supply (UPS) system includes a plurality of UPSs configured to be output paralleled. Availability information is communicated from the UPSs, and an aggregate availability of the UPSs is determined responsive to the communicated availability information. Parallel provision of power from the UPSs may be selectively enabled responsive to the determined aggregate availability. The aggregate availability information may also be reported to a user. The aggregate availability may be, for example, a redundancy level and/or a percentage availability provided by the UPSs. The invention may be embodied as methods, apparatus and computer program products.

摘要： The subject invention pertains to a method, apparatus, and composition of matter for producing near-infrared (near-IR) radiation. The subject invention can incorporate a polymer and a metal-containing compound, wherein the metal-containing compound can incorporate a metal-ligand complex, wherein when the metal-ligand complex becomes excited, energy is transferred from the ligand to the metal, wherein, the energy transferred to the metal by sensitization is emitted as near-infrared radiation. In a specific embodiment, the subject invention relates to a composition of matter having a luminescent polymer and a metal containing compound where the metal containing compound incorporates a metal-ligand complex such that the absorption spectrum of the metal-ligand complex at least partially overlaps with the emission spectrum of the luminescent polymer. As the absorption spectrum of the metal-ligand complex at least partially overlaps with the emission spectrum of the luminescent polymer, when the luminescent polymer becomes electronically excited energy can be transferred from the luminescent polymer to the metal-ligand complex. At least a portion of the energy transferred from the luminescent polymer to the metal-ligand complex can then be emitted by the metal-ligand complex as near-infrared radiation. The subject invention can incorporate polymers which are conjugated or non-conjugated and luminescent or non-luminescent. In a specific embodiment, conjugated polymers which are luminescent can be utilized.

摘要： A low-profile transformer or inductor includes a leg of a magnetically permeable core. A tube-type winding arrangement is made by use of a flat, flexible dielectric sheet, on one side of which a broad conductive area is affixed, and on the other side of which a plurality of mutually parallel elongated regions are affixed. The dielectric sheet is rolled into a tube defining a parting line which is perpendicular to the axes of elongation of the conductive strips. The discontinuous elongated strips are formed into a continuous winding by means of stitches. The stitches may be through vias extending through overlapping regions of the tube to interconnect ends of the strip conductors, or may be generated by an HDI conductor overlying the ends of the strip conductors, with through vias making connections to the ends of the strip conductors and to HDI conductors.

摘要： An apparatus and a method for isolating a biologic product, such as plasmid DNA, from cells. The method involves lysing cells in a controlled manner separate insoluble components from a fluid lysate containing cellular components of interest, followed by membrane chromatographic techniques to purify the cellular components of interest. The process utilizes a unique lysis apparatus, ion exchange and, optionally, hydrophobic interaction chromatography membranes in cartridge form, and ultrafiltration. The process can be applied to any biologic product extracted from a cellular source. The process uses a lysis apparatus, including a high shear, low residence-time mixer for advantageously mixing a cell suspension with a lysis solution, a hold time that denatures impurities, and an air-sparging bubble mixer that gently yet thoroughly mixes lysed cells with a neutralization/precipitation buffer and floats compacted precipitated cellular material.

摘要： A front-end converter processes only a fraction (e.g., about 10%) of the power delivered by an efficient output (i.e., the main) converter in order to control the output voltage thereof. Because only a fraction of the delivered power is processed, the losses associated with the front-end converter are a very small fraction of the total delivered power, leading to very high overall efficiencies. The input power to the front-end converter is provided from the output of the main converter; this reduced power is thus circulated within the converter. Regulation of the output voltage by controlling the dc voltage relieves the regulating function from the main converter, allowing the main converter to be selected strictly on the basis of efficiency and small size. The result is an overall efficient, compact dc-to-dc converter with minimal output filter requirements and protection against output short circuits. Additionally, the converter bandwidth is determined by the bandwidth of the low-power front-end converter which can have a higher bandwidth than a full-rated converter. Therefore, a significantly higher bandwidth can be achieved as compared with presently available converters, advantageously resulting in a reduced output filter size and faster speed of response.
摘要翻译：前端转换器仅处理由有效输出（即主）转换器传递的功率的一部分（例如，约10％），以便控制其输出电压。由于只有一小部分交付的功率被处理，与前端转换器相关的损耗是总传输功率的很小一部分，从而导致非常高的总体效率。前端转换器的输入功率由主转换器的输出端提供; 因此，这种降低的功率在转换器内循环。通过控制直流电压调节输出电压可以减轻主转换器的调节功能，从而可以在效率和体积小的基础上严格选择主转换器。其结果是整体高效，紧凑的直流 - 直流转换器，具有最小的输出滤波器要求和防止输出短路。另外，转换器带宽由低功耗前端转换器的带宽决定，它可以具有比全额定转换器更高的带宽。因此，与目前可用的转换器相比，可以实现显着更高的带宽，有利地导致输出滤波器尺寸减小和响应速度更快。
