Cassandra L. Wellman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11023625
    Abstract: A computational accelerator architecture facilitates change management of works in a model-based system engineering (MBSE) system in which each of the MBSE works includes a plurality of separately-identifiable statements. A linkage data store stores statement-wise, variable-strength linkages between certain statements of the MBSE works, where the linkages are indicative of associations between those certain statements. A revision control engine detects changes made to statements of MBSE works, and selectively indicates calls for revision of other statements in response to those changes based on respective strengths of linkages associated with the changed statements.
    Type: Grant

  • Patent number: 10983190
    Abstract: A PNT sensor short-range relay communication system includes an electronic PNT sensor module configured to determine a first position of the PNT sensor module and to output a PNT signal indicating a second position of the PNT sensor module with respect to the first position. A mobile relay module is in signal communication with the PNT sensor module. The mobile relay module is configured to communicate the PNT signal to at least one terminal device located remotely from the PNT sensor module and the mobile relay module. In this manner, positional information can be determined without relying on a satellite navigation system.
