Abstract: An optical input polarization management device includes a polarization splitter and rotator (PSR) that directs a portion of incoming light having a first polarization through a first optical waveguide (OW).

Light within the third and fourth OW's is input to a second 2x2OS. A second PS is interfaced with either the third or fourth OW. Light is output from the second 2x2OS into a fifth OW for further processing.

Abstract: A method and system for controlling air-interface resources on a radio-frequency (RF) carrier on which an access node provides wireless communication service. While the access node is set to apply at least two resource-reservations (e.g., PRB-reservations) that are mutually exclusive on the carrier, a computing system detects that resource-availability on the carrier is threshold low. And in response to the detecting, the computing system causes the access node to combine together the at least two resource-reservations on the carrier The combining together of the at least two resource-reservations on the carrier retains the at least two resource-reservations on the carrier but results in a reduction in aggregate total quantity of air-interface resources consumed by the at least two resource-reservations on the carrier.

Abstract: When an access node is providing a UE with carrier-aggregation service on a PCell in combination with one or more SCells and the UE engages in a voice call including uplink voice communication on the PCell, the access node will determine that there is a threshold high level of IMD on the uplink resulting from concurrent downlink transmissions, and the access node will responsively swap the UE's PCell with one of the UE's one or more SCells. In a representative implementation, the decision to swap these carriers in the UE's connection could be based on a further determination that the level of IMD on the uplink of the SCell is not threshold high.

Abstract: A system displays summaries of relationships of a selected data asset with other data assets at a limited number of levels upstream and downstream from the selected data asset in rows above and below the selected data asset. In each row, data assets are arranged in order of usage, with most used data asset displayed directly above or below the selected data asset.

The system includes a carousal feature to further navigate the lineage data upstream or downstream. By selecting a new data asset in the parent row, the user can view grandparent-level data assets of the newly selected data asset. The user can view multiple upstream or downstream levels arranged in respective rows displayed above or below the selected data asset. The system can analyze data from any application.

Abstract: Organizations may comprise a variety of resources that are assigned to various organizational units, and allocated for various projects or tasks. A user who wishes to understand the organizational structure of the resources may examine information sources, such as resource manifests and resource access logs, and interpret such information with the user's knowledge of the organization, but may fail to achieve a comprehensive, accurate, and up-to-date understanding of the organization. Instead, interactions among users and resources may be monitored to infer organizational structure; assignment of resources to organizational units; relationships among resources; and usages arising within such resource relationships. Based on such inferences, an interactive visual map may be automatically generated that depicts the arrangement of the organization and the interrelationships of the resources.
