摘要:
Instructions are generated to manipulate target objects and relationships in a relational database when a source object having a one-to-many relationship of privately owned type with the target objects is manipulated. To generate instructions, mapping meta-data is used which contains information as to how object classes of the object model map to tables in the database and how relationships map to foreign keys.
摘要:
A microfluidic device is disclosed comprising a body of refractory material having one or more fluid passages of millimeter-or sub-millimeter scale defined therein and at least one tube of refractory material embedded in said body, the tube having a millimeter- or sub-millimeter-scale passage therein and first and second ends. The tube is desirably, though not necessarily, of a material having a higher softening point than the material of the body. The tube may optionally include a narrowed or “drawn down” portion along the length or at an end thereof to provide extremely fine structure. By shaping depressions or holes to receive the tube in layers of refractory material that are fired or sintered to form the device, the tube can be assembled together with the layers and fired or sintered to form a consolidated refractory microfluidic device.

In an EclipseLink environment, persistence units are associated with a single data source. However, in accordance with an embodiment, a user can define multiple persistence units, each with a different set of entity types (i.e., classes) stored in multiple data sources, and expose them through a single composite persistence unit which combines the entities from across the multiple data sources through a single persistence context. A plurality of different types of data sources can be used, including Java Transaction API (JTA) and non-JTA data sources as well as EclipseLink's native JDBC connection pools. Each member persistence unit continues mapping its classes to its own data source. Therefore, a composite persistence unit allows one to map different entities to different data sources. Composite persistence units can be created at runtime.
摘要:
A high capacity gate array which incorporates an effectively three dimensional interconnect network. The array is formed from multiple smaller arrays which are connected to a common substrate by means of flip-chip bonding. The substrate is typically a multi-layer substrate which has interconnect lines embedded on or within it, thereby allowing a set of desired interconnections between the smaller logic cell arrays to be implemented. The contact points for connecting logic cells or arrays of cells to the substrate result from placing a multitude of solder bumps on the smaller arrays of logic cells at desired interconnect points. Connecting the interconnect point solder bumps to the multi-layer substrate then permits the individual logic cell arrays to be interconnected in a desired manner. A three dimensional interconnect network is realized by interconnecting corresponding points on different logic cell arrays so that the arrays are connected in parallel. This has the effect of producing a three dimensional interconnect network from a two dimensional arrangement of arrays or chips in a MCM package. The result is a high gate capacity logic device having an increased degree of gate utilization and shortened average interconnect distances, thereby enabling the production of complex devices which have a faster operating speed.

A bridge that is attached to a wheelchair such that the bridge allows a wheelchair user to have support for ingress into and egress from the wheelchair without assistance and without the need to rely primarily on arm strength alone. The bridge is a generally L-shaped member that has a pair of aligned slits located on a lower portion thereof such that respective connection members pass through each slit and attach the bridge to a frame of the wheelchair the connection members allowing the bridge to be pivoted out of the way when needed.

The Chronological Data Record Access (“CDRA”) is an internal chain that is used in a Memory Based Database Environment (MBE) to propagate records stored in volatile memory to other mirrored systems, databases, disks, etc. The CDRA associates the latest modified version of a data record and is used to process modified records without the need to queue or move the data image. The CDRA creates support in a shared-nothing environment and time-sequenced handling of information updates so that all entities may work with current information in a timely fashion.
摘要:
Glass-based micropositioning systems and methods are disclosed. The micropositioning systems and methods utilize microbumps (40) formed in a glass substrate (12 or 100). The microbumps are formed by subjecting a portion of the glass substrate to localized heating, which results in local rapid expansion of glass where the heat was applied. The height and shape of the microbumps depend on the type of glass substrate and the amount and form of heat delivered to the substrate. The microbumps allow for active or passive micropositioning of optical elements, including planar waveguides and optical fibers. Optical assemblies formed using microbump micropositioners are also disclosed.

A transverse closed-loop fiber resonator (10) includes an inner cladding (102) having a surface (300) peripherally forming a closed-loop shape for confining light to the surface (300). The inner cladding has a first diameter thickness (104) and a first index of refraction profile in a cross-sectional portion of the transverse closed-loop fiber resonator (10). A ringed-core (120) corresponding to the closed-loop shape is disposed on the corresponding surface of the inner cladding (102). The ringed-core (120) has a second thickness (124) of material thinner than the first diameter thickness (104), and a second index of refraction profile greater than the first index of the inner cladding by an index delta in the cross-sectional portion of the transverse closed-loop fiber resonator such that the ringed-core can guide light within the ringed-core traversely around the closed-loop shape.
