Publication number: 20250392628Abstract: A secure communication system enabling secure transport of information is disclosed. The system comprises a secure network with one or more packet processing units connected by links through an internal communication system. The secure network transports packets of information between credentialed and authenticated agents. Each packet is associated with a visa issued by a visa service. The visa specifies the procedures governing the processing of the packet by the packet processing units as it is transported along a compliant flow, between agents thorough the network, according to a set of policies specified in a network configuration. Packet processing units include docks and forwarders. Adaptors serving the agents communicate with the network through tie-ins to docks. The system also includes and admin service, accessible to one more admins, that facilitates configuration and management of the network.Type: ApplicationFiled: August 29, 2025Publication date: December 25, 2025Inventors: W. Daniel Hillis, David C. Douglas, Mathias Kolehmainen, Steven Willis, Frank Kastenholz, Michael Dubno

Publication number: 20250269092Abstract: Implants including non-resorbable frameworks and resorbable components, as well as methods of use thereof are disclosed. The embodiments include different combinations of a non-resorbable framework (in some case structural and in other cases non-structural), and a resorbable component embedded within and/or around the framework (again, in some cases structural and in other cases non-structural). The disclosed implants provide an efficient means of providing structural support for the vertebral bodies post-implantation, as well as encouraging resorption of the implant and fusion of the associated vertebral bodies without negative side effects and/or failure, such as subsidence of the implant or cracking/fracturing of a portion of the implant when implanted.Type: ApplicationFiled: March 6, 2025Publication date: August 28, 2025Inventors: Bradley William Paddock, Amir Ali Sharifi-Mehr, Adam Laurance Wollowick, Oliver Buchert, Matthew B.
