摘要:
A method of providing services to computing devices includes establishing a connection over the Internet with a computing device; receiving data from the computing device during the connection; extracting a signal from the data received from the computing device; estimating a relative age of the computing device based on the extracted signal; selecting a service from a plurality of services based on the estimated relative age of the computing device; and providing the selected service to the computing device.
摘要:
A vacuum breaker that includes a substantially cylindrical tubular body having a first end and a second end, wherein the first end has a rim extending away from the body and a ledge extending axially away from the rim thus defining an L-shaped profile. A retainer bead extends axially away from an end of the ledge toward the vacuum breaker body, wherein the retainer bead is adapted to provide a friction fit for releasably attaching a flow control insert to the first end of the body of the vacuum breaker. The second end of the body includes a plurality of lip seals, wherein each lip seal defines a slit with a molded hinged member at an end thereof. The hinged member is preferably in the shape of a hole to prevent tearing and maintain the correct slit length.

The invention provides a method of determining the likelihood that a smoker will or will not develop chronic obstructive pulmonary disease (COPD) by obtaining a sample from the smoker, analyzing the sample for the expression of a set of biomarkers associated with COPD, and comparing the expression pattern determined in the sample with a standard expression pattern to determine the likelihood that the smoker will or will not develop COPD. The invention further provides a composition, a method of treatment, and methods of determining the efficacy of treatment for COPD.
摘要:
A diaphragm assembly for use in conventional diaphragm-type flush valves includes a flexible diaphragm body having a first side and a second side and a bypass orifice filter insert defined in the diaphragm body. The second side of the diaphragm body includes an annular protrusion and a plurality of protruding ribs, wherein a recess area is defined between the rib and the protrusion. When a pressure difference is applied across the diaphragm body, the second side of the diaphragm body is concave and the first side of the diaphragm body is convex, whereby a distance between the rib and the protrusion decreases in order to prevent the diaphragm body from closing two quickly against a valve seat of a flush valve. A method for controlling pressure differences across the diaphragm body is also disclosed.

Methods for making medical devices having porous coatings. Methods may comprise providing a tubing section having inner and outer surfaces and positioning a nozzle proximate to a target surface of the parent tubing section. A powder form of the porous coating may be delivered toward the tubing section, and a laser may be directed at the powder to melt the powder to form a melt pool. The melt pool can solidify to form the porous coating on the target surface. Portions of the parent tubing section may then be cut away to form the support structure of the medical device, such as a stent.

摘要:
A method and device for coating a medical device, such as a stent, including forming coating droplets using a mesh nebulizer and transporting the coating droplets to the medical device, for example through a converging chamber. The coating droplets may be accelerated to a speed sufficient to break the coating droplets into smaller droplets upon impact with the medical device. The mesh nebulizer may have a convex inlet side and may form a converging plume of coating droplets. The mesh nebulizer may have one or more groups of pores, the pores within each group may be subject to similar amplitudes of vibration. The coating material may be heated or cooled prior to nebulizing. The chamber may include baffles configured to allow only a predetermined size range of coating particles to pass.
摘要:
An applicator and method of application for a snap wrap marker which may be operated in one embodiment from ground level by a workman with the applicator at the end of a long pole. The pre-coiled plastic marker (for example) is manually uncoiled and its ends positioned to be releasably engaged by pressure holding clips which hold the marker in an open receiving position. The applicator is then raised, (for example) and an opening in the applicator is positioned on either side of the distant cable. The applicator is then pushed so that the marker is pushed downwardly out of the pressure holding clips and then coils itself around and engages the cable. The applicator is then removed leaving the marker coiled around the cable and the applicator ready for another application.
摘要:
A novel class of proteins, semaphorins, nucleic acids encoding semaphorins, semaphorin peptides, and methods of using semaphorins and semaphorin-encoding nucleic acids are disclosed. Semaphorin peptides and receptor agonists and antagonists provide potent modulators of nerve cell growth and regeneration. The invention provides pharmaceutical compositions, methods for screening chemical libraries for regulators of cell growth/differentiation; semaphorin gene-derived nucleic acids for use in genetic mapping, as probes for related genes, and as diagnostic reagents for genetic neurological disease; specific cellular and animal systems for the development of neurological disease therapy.
