US Patent:

6400732, Jun 4, 2002

Filed:

Aug 26, 1999

Appl. No.:

09/384038

Inventors:

Peter J. Castagna - Renton WA
David Randall - Bremerton WA

Assignee:

DMC Stratex Networks, Inc. - San Jose CA

International Classification:

H04J 307

US Classification:

370506, 370509, 375368

Abstract:

A method and apparatus for determining synchronization and loss of synchronization in a high speed multiplexed data system. The system also includes a plurality of justification control bits and a backwards compatibility flag that allows the system to operate with older systems that have fewer justification control bits.

International Classification:

G06K 9/00
H01L 21/66
G06F 17/50

US Classification:

382149, 382144, 382145, 382147, 382148, 438 15, 716 1, 716 21

Abstract:

Various computer-implemented methods are provided. One method for sorting defects in a design pattern of a reticle includes searching for defects of interest in inspection data using priority information associated with individual defects in combination with one or more characteristics of a region proximate the individual defects. The priority information corresponds to modulation levels associated with the individual defects. The inspection data is generated by comparing images of the reticle generated for different values of a lithographic variable. The images include at least one reference image and at least one modulated image. A composite reference image can be generated from two or more reference images. The method also includes assigning one or more identifiers to the defects of interest. The identifier(s) may include, for example, a defect classification and/or an indicator identifying if the defects of interest are to be used for further processing.

Abstract:

A document object may be transmitted to a plurality of user devices. The document object may include at least one field for display of a content object of a group of content objects. The field may be associated with an identifier corresponding to the group of content objects. When the document object is accessed, then the access may trigger a request to a server, which may select a content object of the group of content objects using a content object identification function. The content object identification function may be dynamically updated based at least in part on the document object being accessed by one or more of the plurality of user devices. Responsive to the request, a unique content object identifier corresponding to the selected content object may be transmitted to the user device and displayed at the accessed document object.
