摘要： An image analysis method to quantify visual showthrough of printed images on the reverse face of planar objects, such as paper. An illumination level is set using a white reference object. A white reference image is stored in a computer memory. An image of a planar object having a printed image on the reverse face is stored in a computer memory. A pixel by pixel ratio of the two images is calculated and a mean value of the ratios is calculated to characterize the visual showthrough. The measurements are substantially independent of both the illumination level and image shading.

摘要： The present invention relates to fiberglass loose-fill insulation that is insensitive to the content of boron in the composition of the glass. It has been discovered that the level of boron in the glass used for the manufacture of loose-fill glass wool can be substantially reduced without degrading thermal performance. The lowered amount of boron provides for a lower cost batch composition and increased furnace life. The glass composition of the present invention includes a substantially reduced content of boron and preferably an increased amount of sodium dioxide. The primary phase of these glass compositions is typically devitrite (Na2Ca3Si6O16). The glass of the present invention provides a glass fiber blowing wool that does not require an increase in pack density to compensate for the reduced boron content while achieving the similar thermal conductivity. The glass of the present invention is also suitable for use in acoustic insulation.
摘要翻译：本发明涉及对玻璃组合物中硼含量不敏感的玻璃纤维松散填充绝缘体。已经发现，用于制造松散填充玻璃棉的玻璃中的硼含量可以大大降低，而不降低热性能。硼量的降低提供了较低成本的批料组合物和提高的炉子寿命。本发明的玻璃组合物包括显着降低的硼含量，优选增加二氧化钠的量。这些玻璃组合物的主相通常是二氧化钛（Na 2 Si 3 O 3 Si 6 O 16）。本发明的玻璃提供了一种玻璃纤维吹制羊毛，其不需要增加包装密度，以补偿降低的硼含量，同时实现类似的导热性。本发明的玻璃也适用于隔音。

摘要： A method and apparatus for collecting and forming loose fill fiber material from an air stream includes introducing a combined fiber and air stream onto a surface of a rotatable drum. The rotatable drum allows the air to flow through the surface of the drum while collecting the fiber material on the surface of the drum.

摘要： A method and circuit are presented for an all-optical format independent preprocessor that processes an arbitrary optical input signal by converting a NRZ signal to a PRZ signal, or if the input optical signal is RZ, by merely amplifying it. The method involves subtracting a delayed copy of the signal from the original, thereby effectively doubling its frequency, and inserting a pulse at each transition of the original signal, whether rising or falling. In a preferred embodiment this stage is implemented via an integrated SOA in each arm of an asymmetric interferometric device. The asymmetry consists of a delay element in one arm. In a preferred embodiment the entire device is fabricated on a semiconductor substrate, allowing for compactness as well as minimization of interconnectivity losses and overall power consumption. The output of the preprocessor, having a significant frequency component at its original clock rate, can then be fed to a clock recovery stage for all-optical clock recovery.

摘要： The present invention describes a catheter suitable for introduction into a tubular tissue for dissolving blockages in such tissue. The catheter is particularly useful for removing thrombi within blood vessels. In accordance with the preferred embodiments, a combination of vibrating motion and injection of a lysing agent is utilized to break up blockages in vessels. The vessels may be veins, arteries, ducts, intestines, or any lumen within the body that may become blocked from the material that flows through it. As a particular example, dissolution of vascular thrombi facilitated by advancing a catheter through the occluded vessel, the catheter causing a vibrating, stirring action in and around the thrombus usually in combination with the dispensing of a thrombolytic agent such as urokinase into the thrombus. The catheter has an inflatable or expandable member near the distal tip which, when inflated or expanded, prevents the passage of dislodged thrombus around the catheter. The dislodged portions of thrombus are directed through a perfusion channel in the catheter, where they are removed by filtration means housed within the perfusion channel before the blood exists the tip of the catheter. Catheters that allow both low frequency (1-100 Hz) vibratory motion and delivery of such agents to a blockage and a method for using such catheters are disclosed.

摘要： The present invention relates generally to the treating of wells, and more particularly to a method and device that are capable of detecting the position of a fluid interface so that a well treatment can be placed with greater along hole depth precision in a given hydrocarbon producing well than previously. More particularly, an embodiment of the invention includes a method for accurately placing a well treatment fluid in a well, comprising: pumping a first fluid into a first part of the well until an interface is formed between the first fluid and a second fluid; extracting information regarding at least one fluid property of the first and second fluids with first and second to sensors positioned in the first and second fluids respectively; and exchanging information between the first and second sensors and a telemetry unit. The invention also includes a downhole tool for positioning a fluid interface in a well bore, comprising: first and second sensors, the spacers being spaced apart such that they span the fluid interface; the first sensor measures a first fluid property and the second sensor measures a second fluid property; a first fluid port on the same side of the first sensor as the spacer and in fluid communication with a first fluid flow line; and a second fluid port on the opposite side of the first sensor as the spacer and in fluid communication with a second fluid flow line.

摘要： Systems, methods, and devices for determining neutron-gamma density (NGD) measurement of a subterranean formation that is accurate in both liquid- and gas-filled formations are provided. For example, a downhole tool for obtaining such an NGD measurement may include a neutron generator, neutron detector, two gamma-ray detectors, and data processing circuitry. Neutron generator may emit neutrons into a formation, causing a fast neutron cloud to form. Neutron detector may detect a count of neutrons representing the extent of the neutron cloud. Gamma-ray detectors may detect counts of inelastic gamma-rays caused by neutrons that inelastically scatter off the formation. Since the extent of the fast neutron cloud may vary depending on whether the formation is liquid- or gas-filled, data processing circuitry may determine the density of the formation based at least in part on the counts of inelastic gamma-rays normalized to the count of neutrons.
