摘要:
Techniques for developing a graphical editor using an incremental development approach. Externally-stored descriptors are used to specify information on which a graphical editor engine operates to create a graphical editor. Developers can thus redefine the look and feel of the graphical editor by modifying these descriptors, effectively re-configuring the elements of visual models without changing the code of the graphical editor engine. Visual models for modeling a domain can be created and used, without first requiring the domain model to be defined.

摘要:
A water pillow for coupling acoustic energy into tissue. The pillow is configured to conform to a transducer to facilitate coupling of ultrasound energy. The pillow includes a pouch that accommodates the transducer to enable a snug fit between the pillow and the transducer. The pillow includes a liquid inlet and outlet to facilitate liquid circulation for cooling, is biocompatible, has a low attenuation, is conformal to the shape of the transducer, facilitates use of an adjustable pressure to achieve various standoffs, includes an integral pouch to facilitate an interference fit to the transducer, facilitates water circulation for cooling, is sterilizeable, and is disposable. Either the surface of the pillow adapted to conform to a tissue interface, or the surface of the pillow adapted to conform to the transducer, or both, can include pores configured to weep liquid to facilitate acoustic coupling of the pillow with the transducer and/or tissue.
摘要:
A dryer for use with chemical compounds employs controlled vacuum, elevated temperature and dry, inert gas to dry the chemical compounds. The dryer includes a vacuum chamber into which trays containing the compounds are placed. The chamber includes heating elements which elevate the temperature of chemical samples placed within the chamber. Supplying and evacuating manifolds, each with a plurality of orifices for supplying and evacuating dry inert gas, provide a substantially laminar flow of dry inert gas just above the trays of chemical compounds which are to be dried. The laminar gas flow removes the unwanted vapor which tends to form above the tray of chemical compound, thus accelerating the drying process.
