Abstract: Methods of forming materials containing precursors to electrically conductive polymers and electrically conductive polymers are described which have a high degree of crystallinity. The high degree of crystallinity is achieved by preparing the materials under conditions which provide a high degree of mobility to the polymer molecules permitting them to associate with one another to form a crystalline state. High levels of electrical conductivity are achieved in in the electrically conductive materials without stretch orienting the material. The enhanced electrical conductivity is isotropic as compared to a stretch oriented film which has isotropic electrical conductivity. In the preferred embodiment, additives are added to a solution containing a solvent and the precursor or electrically conductive polymer. The additives are preferably plasticizer of diluents. As the solvent is removed the material dries and contains a higher degree of crystallinity than in the absence of the additive.

Abstract: Collapsible portable self-supporting shelter structures having from at least two component quad sections to seven or more component quad sections, which joined end to end form the width of the structure; and, said entire component sections optionally being joined side to side form a desired depth of the portable shelter. The resulting structure is a collapsible self-supporting prefabricated deployable shelter having a clear span interior without supporting columns. Some versions of the collapsible portable self-supporting shelter structure due to its configuration may optionally contain a floating hub which is a top element extending above the structure's standard exterior matrix frame. The floating hub forms a high pitch atop the shelter, which high pitch causes the fabric, which covers the matrix frame, to be maintained in a taut downward-sloping condition over the shelter top surface so no rain or snow collects in the fabric at the top of the shelter.

Abstract: A method and an apparatus of minimizing the deposition of debris onto a sample being ablated. The method comprising the steps of: 1) reducing a laser pulse energy to approximately a threshold level for ablation; and 2) ablating a region of the sample using a multitude of laser pulses, each pulse being sufficiently separated in time to reduce a concentration of ablation products in a gas phase. An apparatus for ablating a region of a sample with a laser beam. The apparatus comprises: 1) a source providing a pulsed laser beam of a certain energy, the source focusing the laser beam on the sample to ablate a region of the sample; and 2) a device for providing a flowing fluid over the region being ablated to remove the ablation products.

Abstract: LGA connectors are fabricated with buttons or spring contacts preformed to different heights to accommodate the initial topography of a typical module or PCB of a particular product type. This is accomplished during fabrication by measuring topographies of mating surfaces of a first electronic device and of a second electronic device; fabricating interposer contacts to form opposing non-planar sides having respective inverse topographies for contacting the mating surfaces; and sandwiching the interposer between the first and second electronic devices with the opposing sides in contact with respective mating surfaces.

Abstract: An interconnection structure suitable for flip-chip attachment of microelectronic device chips to packages, comprising a two, three or four layer ball-limiting metallurgy including an adhesion/reaction barrier layer, and having a solder wettable layer reactive with components of a tin-containing lead free solder, so that the solderable layer can be totally consumed during soldering, but a barrier layer remains after being placed in contact with the lead free solder during soldering. One or more lead-free solder balls is selectively situated on the solder wetting layer, the lead-free solder balls comprising tin as a predominant component and one or more alloying components.

Abstract: A portable computer adapted for electrical connection to a docking station having multiple power modes of operation is described. The portable computer has one or more CPU chips which have at least two power modes of operation, a low power mode and a high power mode. When the portable computer is operated as a stand-alone computer, it operates in the low power mode. When the portable computer is operated while electrically connected to the docking station, it operates in a high power mode. The docking station has greater cooling capacity than the portable computer alone to provide enhanced cooling of the high power mode of operation.

Abstract: Electronic assemblies, especially one containing volatile memory, used a flexible membrane with conducting lines which acts as an intrusion sensor against chemical and mechanical attacks. The lines are fabricated from inherently conducting polymers which are solution processed and directly patterned. The material was applied to a flexible polymer film by spin coating and patterned by application of a resist, followed by exposure/development of the resist and transferring the image into the polyaniline by reactive ion etching techniques. The conducting lines have high conductivity, tranparency properties which made them difficult to detect and possess excellent adhesion to the substrate film, as well as to the potting material which enclosed the structure. They also offered lightweight advantages over conventionally filled materials. These materials can also be used in conjunction with conventional conductor materials to further enhance protection against intrusion by sophisticated mechanical means.

Abstract: A Resource Management and Reservation System (RMRS) for managing and reserving storage bandwidth, is a platform independent middleware layer that provides an interface to applications, their database management systems, or some other higher level data management systems like ADRS which does data management on behalf of the applications. RMRS is highly relevant in hosted environments where one or more applications may be run on behalf of multiple customers each with a unique service level agreement with the Service Provider. Through its interface to the aforementioned applications, RMRS allows each application or an application side management system to communicate expected future storage access requirements (e.g., periodic access for backups). The interface also allows applications to request urgent storage access (e.g., recovery actions may be requested without being planned ahead of time).
