摘要:
A method and apparatus are described that may be used to provide decoupled rotation of structures about different pivot points. The apparatus may include one or more fixed blades mounted to a frame or substrate, one or more movable blades mounted to each structure to be moved, and flexures on which the structures are suspended. Separate movable blades may be provided for each degree of freedom. When voltage is applied between the fixed and movable blades, the electrostatic attraction generates a force attracting movable blades toward blades that are fixed relative to the moveable blades, causing a structure to rotate about the flexures. The angle of rotation that results may be related to the size, number and spacing of the blades, the stiffness of the flexures and the magnitude of the voltage difference applied to the blades. The blades are fabricated using deep silicon etching.

A mobile chiropractic vehicle comprising a rectangular enclosure have two opposed end walls, two opposed lateral walls, a ceiling and a floor defining an interior area; at least one axle having a pair of wheels, each on opposite ends of the axle, the at least one axle being secured transversely to the rectangular enclosure adjacent the floor to enable movement of the rectangular enclosure; a first arrangement associated with one of the two opposed end walls to transport the rectangular enclosure to selected locations; a second arrangement associated with the other of the two opposed end walls to provide handicapped access to the rectangular enclosure; and a retractable arrangement disposed between the two opposed lateral walls in a spaced relationship with the two opposed end walls to divide the interior area into a patient waiting area adjacent the second arrangement and an examining, diagnostic and adjusting area adjacent the one of the two opposed end walls when the retractable arrangement is closed and a viewing area for a multimedia chiropractic presentation projected on a screen adjacent the one of the two opposed end walls when the retractable arrangement is open.
摘要:
A distributed object-oriented geospatial database system and method thereof over the Internet using Web-based technology to perform data-driven queries, such as retrieving, viewing and updating, geospatial data of the object oriented geospatial database, such as vector, raster, hypertext and multimedia data, including data types or formats of ESRI shape files, GSF, oceanographic ASCII text data by NAVOCEANO and geospatial data with temporal information and supporting 3D display of the geospatial data. The object-oriented geospatial database system is implemented in a heterogeneous object-oriented development and integration environment through the Common Object Request Broker Architecture (CORBA).
摘要:
An object-oriented system for building and maintaining a spatial data structure for use in topological applications. The data is organized in a database which incorporates spatial feature location, attributes, and metadata information in a relational framework across a hierarchy. The system provides for the instantiation of the objects and levels that make up the database and for spatially indexing the data among the objects across hierarchical levels. The data can be updated while preserving the spatial linking among objects and levels, and the data can be exported to a relational vector product format database.
摘要:
A dispensing apparatus comprises a robot device (14) having gripping means (20a, 20b) presentable to a plurality of stations, each station being adapted to provide an operation in a sequence of operations such as to produce a measured quantity or dose from a supply of a hazardous substance, and one of the stations (32) comprising a multi-syringe receiving and filling station comprising syringe receiving means (106) capable of receiving and holding syringes of different sizes each adapted to contain a said substance, the said station having means (95) for operating each syringe when located at that station whereby syringes of different sizes may be operated automatically as selected. The said station may comprise a hazardous liquid filling station for filling items one of which comprises a syringe. The hazardous substance dispensed by the apparatus may comprise a radionuclide, a cytotoxin, a chemotherapeutic agent or a dangerous substance containing one or more bacteriological or viral ingredients or material used in positron emission topography. The said sequence of operations including operations at the filling station may include operations to: (a) elute material from a concentrated source to a user stock source, e.g. in a stock bottle; (b) preparation of different strength doses from the stock source; and (c) preparation of individual patient doses from the appropriate selected doses.

A method of enhancing capabilities is provided. A family of systems capability and operational analysis is conducted to generate a set of operationally decomposed capability needs. Further, a family of systems functional analysis and allocation is conducted on the set of operationally decomposed capability needs to determine a set of deficiencies. In addition, a family of systems design synthesis is conducted on the set of operationally decomposed capability needs, a set of existing solutions, and a set of emerging solutions to identify and describe an optimal integrated solution set of existing solutions and emerging solutions to satisfy the set of operationally decomposed capability needs. Further, the optimal integrated solution set of existing solutions and emerging solutions is generated from the family of systems design synthesis.
