Publication number: 20250119172Abstract: Distributed radio frequency (RF) communication systems for automotive are disclosed herein. In certain embodiments, an RF communication system for an automobile includes an RF module located close to an antenna to satisfy a specified output power with small insertion loss. Additionally, the baseband processor is placed remotely from the RF module in a different area of the automobile to provide a lower temperature environment. Additionally, the RF module communicates with the baseband processor in a digital format eliminating the need for higher cost cabling (for instance, due to higher noise immunity arising from using digital signaling) and using digital transfer cabling, which can already be present in the automobile for other purposes. The RF module can include an RF front-end (RFFE) and a transceiver used for providing frequency conversion, for instance, between RF and baseband.Type: ApplicationFiled: October 23, 2024Publication date: April 10, 2025Inventors: Sabah Khesbak, Mark Alan Richey, Ari T.

Patent number: 12271424Abstract: A server computing device including one or more server memory devices storing a relational database. The server computing device further includes one or more server processing devices configured to receive an ephemeral graph database request. The ephemeral graph database request indicates a selection of data stored in the relational database. The processing devices generate an ephemeral graph database that encodes the selected data in a graph structure and store the ephemeral graph database in binary large object (BLOB) storage at the one or more memory devices. The processing devices receive instructions to apply a graph analytics algorithm at the ephemeral graph database. The processing devices read the ephemeral graph database from the BLOB storage and apply the graph analytics algorithm to the ephemeral graph database to generate a graph analytics result. The processing devices output the graph analytics result and delete the ephemeral graph database from the BLOB storage.Type: GrantFiled: August 28, 2023Date of Patent: April 8, 2025Assignee: The Boeing CompanyInventors: David Richard Bowman, Mary Kay Van De Vanter
