摘要： A trans-illumination device includes at least first and second sets of LEDs of two or more different colors arranged in a light head placed against a patient's skin. The LEDs are mounted to a printed circuit board in the light head. An electronic control circuit is coupled to the light head by an electrical cable to selectively operate the LEDs in two or more user-selected modes, with the ability to adjust the relative intensities of the different colors to best suit the physiology of the patient. The light head may have a U-shape to surround an area of interest while providing ready access thereto. The light head may be used with a disposable, detachable cover having lenses for directing light from the LEDs into the patient's tissues.

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： Disclosed is a system for handling large area, in-process, circuit panel layers. The circuit panel layers are thin and flimsy, and require rigid support for certain processing steps. The system includes a peripheral frame fixture for surrounding and supporting the in process circuit panel layer, and a a loading chuck for mounting the in-process circuit panel layer in the peripheral frame fixture. The peripheral frame fixture includes a bottom plate having a central opening to expose the circuit panel layer, a top frame having a corresponding central opening to expose the opposite surface of the circuit panel layer, and a compressive apparatus, as screws, bolts, or the like, for applying a z axis compressive force to the bottom plate, the top frame, and a panel layer therebetween. Optionally, the fixture may include alignment pins or fiducials for aligning the bottom plate, a panel layer, and the top frame, and a robotic interface for a robotic arm to grasp and transfer the peripheral frame fixture. The system also includes a loading chuck for mounting the in-process circuit panel layer in the peripheral frame fixture. The loading chuck includes a peripheral edge for receiving the bottom plate of the peripheral frame fixture. This provides co-planarity of the in-process circuit panel layer, the bottom plate of the peripheral frame fixture, and the vacuum table. The vacuum table is within the area bounded by the peripheral edge of the loading chuck and the peripheral frame of the peripheral frame fixture, and is coplanar with them. The vacuum table includes slidable bearing surfaces, with vacuum apertures for drawing a vacuum to hold the panel in place, and slide actuators for moving the slidable bearing surfaces to apply x-y axis tension to a panel on the bearing surfaces.

摘要： The present invention provides a power regulation system and method with high speed signal settling capabilities for providing rapid active transient response to a microelectronic device. An active transient response system includes a power supply configured to receive external and/or internal signals indicating the occurrence of transient load conditions and to respond to the transient load conditions based on one or more of these signals. The system may further include a transient suppressor configured for early detection of transients, assisting in transient suppression, and early signaling of transient activity to the power supply.The system provides rapid recovery to steady state operation from the active transient response mode by using a digital compensator to quickly modifying the duty cycle and provide a voltage offset proportional to the transient microprocessor load step. Recovery is further improved by current rephasing techniques.

摘要： A method of making a circuitized substrate which may be utilized as a chip carrier structure. The method involves the steps of providing a dielectric member and partially routing this member to define a temporary support portion therein. Metallization and circuitization may then occur, following which the temporary support portion is removed. This temporary support thus assures effective support for the photoresist used as part of the circuitization process. Thus, the photoresist is capable of being applied in sheetlike form for spanning the relatively small openings of the dielectric without sagging, bowing, etc., which may adversely impact subsequent processing steps.
