摘要:
A method for generating geocoded data for a wireless communication system works over a plurality of network architectures and location processes. The method identifies the presence of mobile activity in the wireless communication network and in response collects wireless communication measurement data associated with the mobile activity. Geolocation is performed on the mobile associated with the activity and the geolocation and measurement data are combined forming geocoded data. The geocoded data is then supplied to a processing system to support implementation of optimization of the wireless network.

The present invention is directed to syntheses of cyclolinear networks. Two novel cyclic siloxanes were used as starting materials. The cyclic siloxanes are self-condensed and co-condensed with silanol-terminated polydimethylsiloxane to vinyl-terminated cyclolinear polymers. Cyclolinear networks can be synthesized by hydrosilylation of vinyl-terminated cyclolinear polyorganosiloxanes with a copolymer of dimethylsiloxane and methylhydrosiloxane.

A process and system for quality assurance. The process includes developing a high level quality assurance resource estimate and a high level quality assurance time estimate; producing a business analysis outline; and creating an acceptance test plan using an acceptance test plan template with the business analysis outline. The process further includes creating a plurality of test cases to be carried out during a test execution phase of the quality assurance process using the acceptance test plan; refining the high level quality assurance resource estimate and the high level quality assurance time estimate based on the acceptance test plan; executing each of the test cases in an acceptance test to produce a set of test results for each of the test cases; and evaluating the test results against the refined high level quality assurance resource estimate and the refined high level quality assurance time estimate. One or more defects tracked during the execution of the test cases are reported and a sign off of the acceptance test is negotiated with a client. An application audit package is created and stored for future reference.

Anti-reflective coating materials for deep ultraviolet photolithography include one or more organic dyes incorporated into spin-on-glass materials. Suitable dyes are strongly absorbing over wavelength ranges around wavelengths such as 248 nm and 193 nm that may be used in photolithography. A method of making dyed spin-on-glass materials includes combining one or more organic dyes with alkoxysilane reactants during synthesis of the spin-on-glass materials.

An improved two part detachable shaft device is connected to a rotatable cutting and shredding member of a comminutor. When these detachable shaft devices are mechanically key connected to the rotatable member along the axis of the comminutor on opposite sides thereof, the shafts and rotatable member form an effective unitary rigidly mounted rotor along the axis of the comminutor and perpendicular to the flow of fluid through the comminutor. Each detachable shaft device provides a unique and convenient means whereby a comminutor cutting and shredding member or both or either shaft device may be readily and efficiently removed for repair or replacement. Each of the detachable shaft devices includes a unique bearing sealing arrangement into which each end of the shaft not connected to the rotatable member extends. One shaft is characterized as the blind side, which provides axial support and sealing of the rotor only, while the other shaft is characterized as the drive side, which provides axial support, fluid sealing and torsion drive through the shaft to the rotor within the comminutor.

The present invention generally relates to polyurethanes and polyurethane nanocomposites having improved mechanical, rheological, and thermal properties over ordinarily produced polyurethanes and polyurethane nanocomposites. Such polyurethanes and polyurethane nanocomposites include very small amounts of a small chain diol, such as glycerol, and more specifically, between 0.01 and 4 weight percent of the small chain diol, based on the total polymer composition.

A vent cover assembly is disclosed, such as for a floating or fixed floor. Example vent cover assemblies may include a support plate configured to be secured over a duct, and a flush mount vent cover. The support plate may define a plurality of first airflow apertures configured to permit airflow from the duct through the support plate. The vent cover may define a second plurality of airflow apertures that are positioned in the vent cover such that the second plurality of airflow apertures are aligned with the first airflow apertures when the vent cover is in a first installed position overlying the support plate. The vent cover may obstruct the first airflow apertures when the vent cover is in a second installed position overlying the support plate.

Sulfur containing, hydroxyl-telechelic PIBs, hydrolytically and oxidatively resistant, biocompatible and biostable polyurethanes (PUs) made therefrom, and methods for making both are disclosed. Well-defined hydroxyl telechelic PIBs are synthesized by a thiol-ene click photochemical reaction between PIBs carrying unsaturated end groups and 2-mercaptoethanol (HS—CH2CH2—OH). This regioselective process affords HO—CH2CH2—S-PIB-S—CH2CH2—OH (abbreviated herein as HO—S-PIB-S—OH) in high yield. In some embodiments, these HO—S-PIB-S—OH polymers may be reacted with diisocyanates and a chain extender to form sulfur containing PIB-based PUs. These sulfur containing PIB-based PUs have been found to have properties and chemical stability that are very similar to that of PUs made from di-hydroxyl terminated PIBs (OH-PIB-OHs) without sulfur, but have surprisingly increased creep resistance and are easier and less expensive to make.

A PIB-based polymer network includes at least one sulfur containing segment and at least two PIB polymer segments. The at least two PIB polymer segments each include a core and at least two polyisobutylene polymer chains extending therefrom. The at least one sulfur containing segment includes at least one sulfur atom that is located between any two polyisobutylene polymer chains from two different PIB polymer segments, so that the sulfur containing segment connects those two different PIB polymer segments together. The PIB-based polymer network is produced by the thiol-ene reaction in the presence of light or heat. The reaction products include at least two polyisobutylene polymer precursor moieties, each polyisobutylene polymer precursor moiety having at least two end group selected from the end groups —CH2—CH(CH3)═CH2, —CH2═C(CH3)2, and —CH2—CH═CH2; and at least one multi-functional thiol.
