Patent CA-2231575-A1 (CA)
Title: Call routing in an atm switching network
Inventor: YAN JAMES
IPC: H04L12/56
Filed: 1996-10-16
Abstract: A routing scheme for an ATM switching network includes a plurality of switching nodes, each of which includes individual storage for storing routing messages for each outgoing link. A call at a source node is routed through one possible routing path which requires only one or two links to complete a connection to a destination node. In such case, one of the routing paths is selected based on link state information concerning only the possible routing paths. If the call requires a route path which includes three or more links to the destination node, the source node performs a predefined sequential routing to its neighboring node before the neighboring node negotiates with selected intermediate nodes for a connection involving two links. The routing messages stored at each node are processed independently and simultaneously by each node. The main requirement is that routing decisions must be based on true link-state information. A protocol is devised for fast and efficient bulk processing while avoiding potential deadlocks.

Title: Multi-path interference filter
Inventor: BHAGAVATULA VENKATA A

Filed: 1997-02-03
Abstract: An interference filter (10, 30, 50, 70, 90, 110, 130, 150, or 190) filters selected wavelengths by dividing an input beam into two or more intermediate beams having different optical path lengths and by recombining the intermediate beams into an output beam that is modified by interference between the intermediate beams. An optical path length difference generator (20, 40, 60, 80, 100, 120, 140, 160, or 200) varies the optical path lengths of the intermediate beams by changing the physical lengths of their paths or the refractive indices of the mediums in which they are conveyed. The optical path length generator (20) of one exemplary embodiment (10) includes a spacer plate (20) that is divided into solid optical elements (22 and 24) having different refractive indices for varying the optical path lengths of the intermediate beams. Another optical path length difference generator (140) is formed by a stack of partially reflective surfaces (144) that are spaced apart in the direction of beam propagation by at least one nominal wavelength for varying the physical path lengths between the intermediate beams.

Abstract: An apparatus and a method perform search operations on a document having nested elements of varying types.  The apparatus finds in the document an element which is capable of containing nested elements of one or more varying types.  The apparatus can also replace the found element with a substitute element, which is also capable of containing nested elements of one or more varying types.  The types of elements include texts, images, animation, and sound clips.  For each element, a matching function and a find function are provided.  The matching function associated with one element determines if a target element matches itself based on predetermined search criteria.  The find function associated with one element searches for a match of a target element within itself.  The find function of one element can in turn invoke find functions associated with elements embedded within itself in carrying out the search on the target element.

Inventor: HIRAI RENZO
IPC: G01N22/00
Filed: 1998-12-15
Abstract: Microwaves are respectively propagated through a reference fluid and fluid to be measured, both contained in a detection pipe body, and as a result, a first phase lag .theta. 1 and a second phase lag .theta. 2 can be determined on the basis of the microwaves by a phase lag measuring circuit.  Then, a density computing circuit subtracts the first phase lag .theta. 1 from the second phase lag .theta. 2 to determine a phase difference .DELTA..theta..  When computing the density of matter in the fluid on the basis of the phase difference .DELTA. .theta., the density computing circuit performs density computing processing such that a real second phase lag .theta.2 satisfies the following equation .theta.2 = .theta.2' + N x 360° where N is the number of rotations, and .theta.2' is an apparent phase lag obtained by the phase lag measuring circuit.  Then, if the density does not fall within a checking range defined by upper and lower limit values, a rotation-number checking circuit increases or decreases the number N of rotations such that the density falls within the checking range.
