Abstract: A photoelectric sensor array is labelled by accumulating charge, preferably charge from a dark current, in at least a portion of the sensor array and reading out the accumulated charge to form an image to determine locations of atypical pixels in the portion of the sensor array. A signature of the sensor array is generated from the locations of atypical pixels and stored. The array is subsequently identified by re-accumulating charge in the portion of the array to form a signature based on the atypical pixels for comparison with the stored signature.
Abstract: A method and a device for producing slots in workpieces are disclosed. An oscillatory drive is provided, on the output shaft of which a saw blade is accommodated by one end, and at the other end of which a cutting edge is provided. The oscillatory drive is positioned on a workpiece with a defined angle between the workpiece surface and the saw blade, the saw blade being driven in an oscillating manner and moved along a guide in a direction extending radially in relation to the output shaft. Connecting elements can be inserted into slots produced on two workpieces in this way so that they match and can be adhesively bonded to the two workpieces, in order to produce a permanent and precise connection between the workpieces.

Abstract: Provided are processes for enhancing the resolution of a thermally transferred pattern on an imaged thermal transfer receiver, wherein the imaged thermal transfer receiver comprises a surface having an exposed portion and a non-exposed portion of one or more thermally transferred layer(s), comprising: (a) contacting said surface with an adhesive layer for a contact period to provide a laminate; (b) separating said adhesive layer from the laminate to provide a treated thermal transfer receiver having a surface substantially free of said non-exposed portion of one or more thermally transferred layer(s). The processes are useful in the fabrication of electronic devices including thin film transistors, circuits, electromagnetic interference shields, touchpad sensors and other electronic devices.

Abstract: Processes for reducing color in PO3G are provided. The processes include contacting PO3G with an activated carbon and then separating the PO3G from the activated carbon by, for example, filtration. The process provides PO3G having an APHA color less than that before contact with the absorbent. The processes are desirably used for polymers having a molecular weight of about 250 to about 5000.
Abstract: Provided are multilayer laminates having one or more layers comprising twisted nematic liquid crystals and one or more layers of a polymeric sheet comprising a polymer with a modulus of 20,000 psi (138 MPa) or less. The twisted nematic liquid crystal layers reflect infrared radiation. Thus, the multilayer laminates are useful to reduce the transmission of infrared energy. For example, in some embodiments the multilayer laminates are useful as windows to reduce energy consumption necessary to cool the interior of a structure such as an automobile or building. Preferably, the multilayer laminates retain the beneficial properties of safety glass. The multilayer laminates may include additional layers such as infrared absorbing layers, half wave plates, and the like, to minimize the transmission of infrared energy. The multilayer laminates may also include further additional layers such as polymeric films, polymeric sheets, rigid sheets, and the like.

Abstract: Water absorption resistant polyimide/epoxy-based compositions, like pastes (or solutions), are particularly useful to make electronic screen-printable materials and electronic components. A group of hydrophobic epoxies (and soluble polyimides) was discovered to be particularly resistant to moisture absorption. The polyimide/epoxy pastes made with these epoxies (and these polyimides) may optionally contain thermal crosslinking agents, adhesion promoting agents, blocked isocyanates, and other inorganic fillers. The polyimide/epoxy pastes of the present invention can have a glass transition temperature greater than 250° C., a water absorption factor of less than 2%, and a positive solubility measurement.

Abstract: A yarn, fabric, and garment suitable for use in arc and flame protection and having improved flash fire protection contains a majority, by weight, of meta-aramid fibers having a degree of crystallinity of at least 20%, and a minority of modacrylic fibers, para-aramid fibers, and antistatic fibers. Garments made from the yarns provide thermal protection such that a wearer would experience less than a 65 percent predicted body burn when exposed to a flash fire exposure of 4 seconds per ASTM F1930, while maintaining a Category 2 arc rating per ASTM F1959 and NFPA 70E.
Abstract: The present invention provides a microorganism useful for biologically producing 1,3-propanediol from a fermentable carbon source at higher yield than was previously known. The complexity of the cofactor requirements necessitates the use of a whole cell catalyst for an industrial process that utilizes this reaction sequence to produce 1,3-propanediol. The invention provides a microorganism with disruptions in specified genes and alterations in the expression levels of specified genes that is useful in a higher yielding process to produce 1,3-propanediol.
