Abstract: A part for a centrifugal breather for an air/oil mixture of a turbomachine is configured to rotate about a longitudinal axis of symmetry. The breather forms an annular chamber for centrifugal separation of said mixture. The chamber includes mesh structure that takes up at least one space in a duct which closes communication between an axial inlet and an internal radial outlet. The mesh structure is formed by the spatial repetition of the material or of the space of a single pattern produced by the interconnection of simple shapes. The pattern is designed such that the spaces between the materials paths passing through the materials in at least three dimensions of space forming a trihedron.

Abstract: A method for ensuring digital wallet security by implementation of a blockchain locking mechanism operable to prevent unauthorized digital token transfer from an owner digital wallet to a third-party digital wallet upon issuance of a paper token certificate. The blockchain locking mechanism is implemented such that compromise of the digital wallet does not results in unauthorized transfer of digital assets. The blockchain locking mechanism utilizes an unlocking code required to transfer asserts from the owner digital wallet to any third-party digital wallet. The blockchain locking mechanism implements an additional security measure and introduces physical security measures to combat cyber security threats. The paper token certificate assures investors of the safety of their digital assets by removing the vulnerability of having a single private key controlling their digital assets.

Abstract: A method and apparatus for cryptographically linking separated authentication and authorization processes to support data transaction signing when group or corporate authority structures are required. The apparatus provides a secure, scalable model to represent authority in an entity context while conducting distributed ledger technology transactions. The method supports a range of cryptographic methods for separating the linked authentication and authorization processes including split key encryption, multi-party computation, multi-signature authorization, and execution of decentralized smart contract authorization logic. The method supports multiple models for authorization including organizational structures, consensus models including voting, and workflow processes.

Abstract: A method and apparatus for secured, peer-to-peer transfer of data rights over a computer network, the method being accomplished by a distributed computing system including a distributed ledger platform. Root rights are defined and delegated to wallets in a multilevel manner to thereby isolate wallets associated with the root right from cyber risk. Root rights are revokable and reassignable, where a root wallet is able to claw back authority delegated to one or more supervisory wallets.

Abstract: One of the drawbacks of Distributed Ledger Technology (DLT) is the conflation of authorization and authentication of transactions on a distributed ledger. The present invention includes a highly adaptable method and system for separating, but cryptographically linking, the authentication and authorization process of signing a transaction of a distributed ledger. The present invention facilitates group authority, common in corporate structures, for proposed transactions, voting models, and even workflow decision making. The present invention supports implementation of a variety of known authorization models into a decentralized network.

Abstract: A system and methods for creating and managing distributed ledger non-fungible token data structures that represent the liquidity function for any two distinct representations of assets. The representations may be different assets or a single asset type with different characteristics including ledger, network, jurisdiction, availability, etc. The liquidity function is the mechanism to transform or exchange the asset including the pricing function, fees, and delivery mechanism. The investment performance of the liquidity token can be proportional to the demand for liquidity for the pair of assets.

Abstract: A method and system for interfacing heterogenous computing networks to accomplish a cross-network that spans at least two networks and has a source node and a destination node. A graph structure is traversed to define a transaction path. The graph structure includes transaction nodes within transfer networks and bridges that span networks. Each node in the graph structure exists on a network and has an associated set of attribute variables that specify supported tokens. A bridge path defined by two nodes spanning two logical networks is determined. The source node and the destination node are also connected via one or more out of band network paths which are separate from the bridge path. Disclosed implementations link the speed and convenience of peer-to-peer conversion models with business-to-business trading channels using a ledger-agnostic overlay and computing architecture to enable value transfers and conversion spanning dissimilar digital communication networks.

Abstract: A framework for managing data on a decentralized network is disclosed. The framework is designed to manage two conflicting forces, openness and control, in order to provide scalable trust on trustless networks. To manage this conflict, a flexible, decentralized governance model is disclosed to enable any DLT user to create and manage data contexts, a virtual boundary for controlling data rights, meaning, and value so as to produce accountable, trusted data with full provenance. The framework does not need to determine who should be trusted, how the trust network forms, or how meaning is developed while providing a governance model by which any authorized user can contribute meaning (properties) and monetize attributable data (attestations).

Abstract: A method and apparatus for secured, peer-to-peer transfer of data rights over a computer network, the method being accomplished by a decentralized computing system including a distributed ledger platform and an off-chain data host platform. A data owner authorizes the minting and distribution of an on-chain authorization token using the distributed ledger. The authorization token includes primary and secondary encryption levels to ensure secure data transfer. The authorization tokens are used to track data access rights, enforce access policies, and control distribution of encryption keys transferred between the data owner, an administrator, a recipient, and/or a delegate.

Abstract: To achieve no code or low code parity in decentralized computing systems, disclosed implementations provide a data structure and trusted control plane that enables the creation and operation of composable objects, that is objects whose functions and properties are derived from configurable and upgradable templates. The templates are data structures that define the behavior of a collection of objects, the behaviors being the interfaces, functions, properties, events, triggers, error messages, and dependencies that define and object and its interaction with other objects and entities. Templates are configured by mapping the desired object behaviors to registered smart contract logic that affects the behaviors. Thus, complex objects can be composed without the need for new computer code. Additional logic to enable new behaviors can be added by authorized smart contract developers and, once certified, added to one or more templates to provide the objects access to the new capabilities.
