Title: Displaying n dimensional data in an n-1 dimensional format
Inventor: STARK TRACY J
IPC: G06T17/05
Filed: 1992-03-24
Granted: 1996-03-19
Abstract: A process for generating a surface slice for use in understanding or comprehending the inter-nal structure of a multi-dimensional dta volume and specifically a three-dimensional seismic data volume. The surface slice is a local N-1 dimension-al representation of the internal structure of N di-mensional data, where N represents the original di-mension of the data volume. Information from the Nth-dimension is preserved in the N-1 dimensional surface slices. An arbitrary surface intersecting sur-faces through the date volume is selected. A var-iant, an identifiable attribute of data which forms the surfaces of finite extent throughout the data vo-lume, is also selected and isolated to identify the surface. Variants can include, but are not limited to, peaks, troughs, local peaks, local troughs, plus-to-minus zero crossings, and minus-to-plus zero crossings. Isolated variants from the arbitrary sur-face are combined onto the arbitrary surface with isolated variants surrounding the arbitrary surface to create the surface slice. Isolated variants identifi-ed by their position in the data volume generate a time surface slice. Both quantitative and qualitative information on the local strike, local dip direction and dip magnitude of the intersecting surface are present. Isolated variants identified in any other manner generate an amplitude surface slice presenting both quantitative and qualitative information on the local strike and dip magnitude of the intersecting surface.

Abstract: A thin film dc SQUID and its driving electronic circuitry configured with very high symmetry. The SQUID loop is formed with four holes (24, 25, 26, 27) at the respective ends of crossed slits (22, 23).

The external driving circuit (75-85) is configured to preserve the highly balanced nature of the chip and forces equal magnitudes of current to flow in all four of the bias leads.

Title: Message routing for sonet telecommunications maintenance network
Inventor: MAZZOLA ANTHONY J
IPC: H04Q3/66
Filed: 1993-03-29
Granted: 1998-11-03
Abstract: A routing method, performed by intelligent network elements of a data communications network having SONET applications, for selecting a path from a source network element to a next network element.  Each network element has access to a database containing the addresses of its neighboring network elements and their types.  To select a next network element, a routing network element first attempts to find a neighboring network element that is the same as the destination network element.  If it has no such neighbor, the routing network element then attempts to find a neighbor that is in the same area as the destination, or failing such a neighbor, in the same routing domain.  Optionally, the routing network element looks for a neighbor that has been selectively provisioned as a next network element.  At each step, candidate network elements are eliminated by using data about their type and application to determine if they call for duplicate paths.
