Abstract: A software modeling environment is presented that supports the development and execution of software that can be dynamically configured. This is achieved by introducing a design-time object modeling construct called a dynamically configurable type (DCT) that supports the subdivision of an object into a plurality of subsets of semantics and allows dynamic merging of these semantic subsets together in different combinations in order to allow the resultant object to exhibit different semantics over time to serve different purposes. Specific process modeling constructs are included which take advantage of this semantic merging capability. Also included are other supporting design-time and run-time constructs and services. One embodiment of the present invention allows this software modeling environment to be integrated into a standard software development environment, enhancing the modeling capabilities already present.

Abstract: Agents for enhancing the contrast in a diagnostic ultrasound procedure comprise colloidal dispersions of the liquid-in-liquid type, i.e., emulsions or microemulsions, in which the dispersed liquid phase is a liquid having a boiling point below the temperature of the animal to be imaged and which therefore undergoes a phase change from a dispersed liquid to a highly echogenic dispersed gaseous foam or kugelschaum following administration to the animal. The liquid state of the dispersed phase allows one to manufacture extremely stable, pharmaceutically acceptable emulsions with particle sizes typically below 1000 nm. The gaseous state at body temperature yields highly echogenic microbubbles, typically below 10,000 nm in diameter, which are effective as ultrasound contrast agents. Intravenous, intraarterial, oral, intraperitoneal, and intrauterine dosage forms, methods of administration, and imaging techniques are described.

Abstract: A movable sheet overlying a wing is disclosed that creates laminar flow over its exposed surface. The movable sheet serves as an integral, retractable shield for protecting a suction support structure of a wing against contamination, and also serves as a movable, conductive substrate for deicing by means of electrical resistance or hot-gas heating. The invention includes a movable sheet that is mounted scroll-like on two motor-driven rollers. The sheet has a solid area without perforations that protects the suction support structure from contamination, and a porous area with perforations therethrough that allows boundary layer suction. The motor-driven rollers scroll the sheet to cover the suction support structure with either the solid area or the perforations of the sheet. Contact rollers at the edge of the sheet supply electrical current to resistively heat the sheet and melt any accumulated ice. The movable sheet can also be moved back and forth to dislodge the ice.

A USB device includes a memory space for reading and writing data transmitted over a USB network. The memory space is shared between a plurality of endpoints. A host initiates a control transfer by transmitting a SETUP token to a first endpoint. The endpoint must accept the SETUP token. If the first endpoint does not expect the SETUP token, or if another endpoint is active, the device stores the token until a buffer is allocated and the first endpoint is made active.

Abstract: An evacuatable storage unit that includes a substantially rigid container having an open upper end, a flexible air tight liner attached to the inside of the container, and a port installed in a surface of the liner that allows air to pass out of the liner and prevents air from entering the liner. The liner has an upper portion that extends out beyond the open upper end of the container. The liner upper portion terminates in an opening for inserting compressible articles into the liner. The opening is closable to form an air tight seal. As air inside the liner is evacuated from the liner through the port (typically by using a household vacuum cleaner), the liner upper portion and compressible articles stored therein collapse into the container.

Abstract: Capacitance between interconnects lines of a semiconductor device is reduced by providing air voids between the interconnects. The air voids are produced by depositing a dielectric over and partially between the pairs of interconnects and the substrate between them, and etching (preferably by sputter etch) in a controlled and coordinated manner so as to produce air voids in the dielectric between the interconnects. The tops of the air voids are below the level to which the uppermost surfaces of the interconnect is then exposed during subsequent processing so that the air voids remain intact during such subsequent processing.
