摘要:
The invention provides a polyurethaneurea composition comprising poly(tetramethylene-co-ethyleneether) glycol having from about 37 to about 70 mole percent ethyleneether content and ethylene diamine as the extender. The invention further relates to the use of high ethyleneether content poly(tetramethylene-co-ethyleneether) glycol as the soft segment base material in spandex compositions. The invention also relates to new polyurethane compositions comprising poly(tetramethylene-co-ethyleneether) glycols with such high ethyleneether content, and their use in spandex.

The invention also relates to new polyurethane compositions comprising poly(tetramethylene-co-ethyleneether) glycols with such high number average molecular weight, from about 1900 to about 4000 Dalton, and their use in spandex.
摘要:
An ink jet printer for printing on an at least partially cylindrical objects comprises one or more printheads positioned above a line of travel and a carriage assembly configured to hold an at least partially cylindrical object axially aligned along the line of travel and to position said object relative to the printheads, and then rotate the object relative to said one or more printheads. The printer also includes a curing device located along the line of travel and configured to emit energy suitable to cure the deposited fluid.
摘要:
A computer-implemented system and method of intra-oral analysis for measuring plaque removal is disclosed. The system includes hardware for real-time image acquisition and software to store the acquired images on a patient-by-patient basis. The system implements algorithms to segment teeth of interest from surrounding gum, and uses a real-time image-based morphing procedure to automatically overlay a grid onto each segmented tooth. Pattern recognition methods are used to classify plaque from surrounding gum and enamel, while ignoring glare effects due to the reflection of camera light and ambient light from enamel regions. The system integrates these components into a single software suite with an easy-to-use graphical user interface (GUI) that allows users to do an end-to-end run of a patient record, including tooth segmentation of all teeth, grid morphing of each segmented tooth, and plaque classification of each tooth image.

摘要:
An apparatus for stretching a plastic film around a package is disclosed wherein two handles are secured to the core of the plastic film, one handle effectively extending the core and having a braking cover for dispensing speed control. The other handle includes a U-shaped member to provide a second grip parallel to, but displaced from the axial centerline of the core. The plastic film is configured between the two handles for rotation about the centerline axis of its core.
摘要:
The present invention provides for a monitoring system and method to monitor an analyte, including determining the presence of the analyte and analyzing the analyte; for example, cellular chorography and biological threats. The system and method use a fluidics apparatus (e.g., a flow cytometer), a computer, a probe synthesizer and/or an initial set of fluorophore conjugated probes to monitor the analyte. The fluidics apparatus is adapted to determine the presence of the analyte based on the intrinsic fluorescence of the analyte, and/or to determine the binding of the probes to the analyte in the sample. The binding information is analyzed by the computer by comparing the binding results with a database of information regarding the analyte. The information gained allows the probe synthesizer to synthesize new probes for a subsequent iteration of the process, wherein additional information regarding the analyte is gained with every iteration.

摘要:
A computer system and method are provided for the verification of functional equivalence between at least two source codes residing on at least one computer. A comparison is carried out between a source code and a modified version of the source code. The comparison is performed to determine the functional equivalence between the two source codes. The functional equivalence is determined on the basis of type, scope and linkage of identifiers of the source codes. The identifiers are extracted from the assembly codes of the source codes.
摘要:
Multiplexed lateral flow assays, related methods, and devices are disclosed which are capable of simultaneously detecting multiple analytes. The assays are preferably immunoassays and can be multiplexed spatially, spectrally, and both spatially and spectrally. Multiplexed assays are disclosed employing quantum dots for applications including the detection of human proteins and the monitoring of microorganisms relevant to water contamination. The invention is widely adaptable to a variety of analytes such as biowarfare agents, human clinical markers, and other substances.
