    摘要: Currents flowing in the various channels within a voltage regulator module (VRM) are suitably converted to digital equivalents that can be processed to control each module in a modular power supply. Functions that may be digitally implemented include current balancing between channels, current sharing between various modules in a power supply, and/or the like. By monitoring the current provided on each channel within a module, for example, a controller can determine an average current for the channels, which in turn can be used to identify and compensate for over- or under-production in any particular channel. Active voltage positioning techniques and overload protection may also be implemented using digital techniques.

    摘要: Disclosed is a parallel processor packaging structure and a method for manufacturing the structure. The individual logic and memory elements are on printed circuit cards. These printed circuit boards and cards are, in turn, mounted on or connected to circuitized flexible substrates extending outwardly from a laminate of the circuitized, flexible substrates. Intercommunication is provided through a switch structure that is implemented in the laminate. The printed circuit cards are mounted on or connected to a plurality of circuitized flexible substrates, with one printed circuit card at each end of the circuitized flexible circuit. The circuitized flexible substrates connect the separate printed circuit boards and cards through the central laminate portion. This laminate portion provides XY plane and Z-axis interconnection for inter-processor, inter-memory, inter-processor/memory element, and processor to memory bussing interconnection, and communication. The planar circuitization, as data lines, address lines, and control lines of a logic chip or a memory chip are on the individual printed circuit boards and cards, which are connected through the circuitized flex, and communicate with other layers of flex through Z-axis circuitization (vias and through holes) in the laminate. Lamination of the individual subassemblies is accomplished with a low melting adhesive that is chemical compatible with (bondable to) the perfluorocarbon polymer between the subassemblies in the regions intended to be laminated, and, optionally, a high melting mask that is chemically incompatible with (not bondable to) the perfluorocarbon polymer between the subassemblies in the regions not intended to be laminated. The subassembly stack is heated to selectively effect adhesion and lamination in areas thereof intended to be laminated while avoiding lamination in areas not intended to be laminated.

    摘要: A porous, filamentary mat has a plurality of layers that are in intimate face-to-face relation and that have portions of the confronting faces thereof bonded together to enable those layers to constitute a unitary, porous, filamentary mat. Each of the layers has a plurality of elongated filaments of thermoplastic material; and each of those filaments is arranged in an essentially horizontal attitude and is longer than the mat. Each of those filaments has a number of bends therein which cause portions of each filament to cross and to engage other portions of that filament; and those bends also cause portions of each filament to cross and to engage portions of one or more adjacent filaments. The crossing portions of each filament, and the crossing portions of adjacent filaments, are bonded together by initial thermal bonds that are subsequently enhanced; as by pressing together the adjacent crossing portions of the various filaments of the mat while they are in a tacky state, by applying additional heat to the initially-thermally-bonded filaments of the mat to cause the initial thermal bonds to form longer and deeper bond, or by applying both heat and pressure to those initial thermal bonds.

    摘要: A pediatric tissue illuminator includes a semi-rigid lighting head removably connected to a powered base unit for illuminating an infant's tissues while stabilizing a limb for venipuncture. The lighting head includes a series of LEDs and is placed behind an infant's arm, thereby directing light therethrough for enhanced viewing. A printed circuit board in the lighting head routes electrical conductors to the LEDs. A translucent soft covering is disposed between the printed circuit board and the infant's body. The base unit includes a control circuit for varying the application of electrical power to the lighting head via an electrical cable. The arm board/light head is inexpensive enough to be disposable. Alternatively, a re-useable light head may be used with disposable semi-rigid housings.

    摘要: The present invention provides a method of ablative photodecomposition and forming metal pattern which attains high resolution, is convenient, and employs non-halogenated solvents. The present invention is directed to a process for forming a metal pattern, preferably circuitization on an organic substrate, preferably on a circuit board or component thereof, which comprises coating the substrate with an ablatively-removable coating comprising a polymer resin preferably an acrylate polymer resin and preferably an ultraviolet absorber. A pattern is formed in the polymer coating corresponding to the desired metal pattern by irradiating at least a portion of the polymer coating with a sufficient amount of ultraviolet radiation to thereby ablatively remove the irradiated portion of the polymer coating. Next the patterned substrate is coated with a conductive metal paste to define the metal pattern, and the conductive metal paste is cured. The remaining polymer coating is removed by solvent stripping with non-halogenated solvents. The present invention further includes patterning electronic structures comprising multilayer circuitry using the above method. An excimer laser is used to form vias or through holes in the electronic structure while simultaneously patterning the polymer coating. This results in perfect alignment between the pattern formed in the polymer coating and the vias or through holes. High resolution circuitry is thus attainable when the electronic structure is subsequently metallized with a conductive metal paste.

    摘要: A control system, method and apparatus is provided for an orthogonally variable inductor. A method and apparatus is also provided for voltage regulation. Regulation is provided without the use of Silicon devices, such as FET's, in the output current path. Efficient voltage regulation is provided via varying the inductance of a device in the output current path, and alternatively via varying the inductance and duty cycle. An orthogonal inductive device is provided to vary the inductance in the output current path. The orthogonal inductive device is an external H field device, a series method orthogonal flux device, or a combined core device. Furthermore, a variable inductor is also provided in filters, amplifiers, and oscillators.
