Abstract: An embodiment includes a method of self-election of a node in a subnet. The method includes receiving a first ping message. The first ping message is unicast from a second node, includes direct information related to the second node, and includes indirect information related to a third node. The method includes updating a first status of the second node in a status list stored at the first node consistent with the direct information. The method includes determining whether statuses of a threshold number of nodes have been received. Responsive to the threshold number of nodes being received, the method includes performing a local election operation. The method includes propagating a second ping message to a randomly identified additional node. The second ping message includes direct information regarding the first node and indirect information regarding at least one other node.

Abstract: A method is provided comprising: monitoring, by a symbol context manager, context switch events that are generated in a virtual machine, and updating a symbol space map based on the context switch events; receiving, by the symbol context manager, a request to provide a symbol space of the virtual machine, the request being generated by a symbol database interface in response to a symbol query that is received at the symbol database interface from a debugger that is debugging the virtual machine, the symbol query being associated with a symbol that is part of the symbol space; and providing, by the symbol context manager, an indication of the symbol space of the virtual machine, the indication of the symbol space being provided based on the symbol space map.

Abstract: A portable air abrasion device has a dispensing chamber and a flow valve for controlling the flow rate from the dispensing chamber. The flow valve includes a fluid flow chamber for receiving granular materials exiting the dispensing chamber. The fluid flow chamber has a granular materials inlet port, a fluid flow inlet port for receiving the flow of a fluid to the fluid flow chamber and a fluidized granular material exit port for dispensing a fluidized mixture of the granular material away from the fluid flow chamber. The fluid flow chamber also has a flow regulator employing a lead screw to control the flow of fluidized granular material through the fluidized granular material exit port.

Abstract: A pollution control device suitable for use with an internal combustion engine (e.g., a diesel engine) and comprising a pollution control element arranged in a casing with non-woven mat disposed between the casing and the pollution control element, said non-woven mat being a non-intumescent mat comprising at least 90% by weight based on the total weight of the mat of chopped magnesium aluminium silicate glass fibers that have a number average diameter of 5? or more and a length of 0.5 to 15 cm, said glass fibers being needle punched or stitch bonded and said mat being free or substantially free of organic binder.

Abstract: A device (10,60) for monitoring the runtime of an engine is disclosed. The device comprises a sensor (30), timer means (20), and means (40) for communicating information regarding the monitored engine runtime to a user. The sensor (30) is adapted to sense vibrational movement that is characteristic of that caused by the engine when running, and the timer means (20) is operably linked to the sensor (30) such that the duration of such vibrational movement, and hence engine runtime, is monitored.

Abstract: The present invention provides certain carboxymethyl cellulose (CMC) esters of higher acids (e.g., CMC acetate propionate, CMC propionate, CMC acetate butyrate, and CMC butyrate)having specific use in aqueous dispersions useful in formulating waterborne coating compositions containing pigments, especially metallic pigments such as aluminum flakes and mica. The esters also have specific use as wetting agents and in high solids coatings.

Abstract: An elastic nonwoven web of microfibers of radiation crosslinked ethylene/alpha-olefin copolymers. The web has an elongation to break of at least 400 percent and generally is comprised of meltblown microfibers. The ethylene/alpha olefin is preferably an ethylene/1-octene copolymer having a density less than 0.9 g/cm.sup.3 and a melting point of less than 100.degree. C.
