Abstract: Some embodiments described herein relate to a computer implemented method that includes performing a first work step associated with a first activity and with a first data product and performing a second work step associated with a second activity and associated with a second data product. A first chain of trust between the first work step and the second work step can be defined by defining a second manifest document that is associated with the second data product and that references a first manifest document associated with the first data product. An immutable data structure representing a second chain of trust independent of the first chain of trust can be defined by submitting the first manifest document and the second manifest document to a distributed ledger for validation.

Abstract: Data backups are performed in multiple blockchain environments. Digital pictures, movies, computer files, apps, and any other electronic data may be automatically backed-up, or duplicated, to multiple blockchain networks. First, an electronic data is written to a first blockchain network. A second, different, blockchain network is automatically selected based on many factors and/or parameters. Then, the electronic data is written to the second blockchain network. Still more duplicate copies of the electronic data may be redundantly written to third, fourth, and more blockchain networks. Any of the blockchain networks may send a confirmation that confirms the duplicate copy was written. One or more cryptographic proofs may be generated to prove the duplicate copies were stored to the multiple blockchain networks.

Abstract: A computer system processes a digital representation of an illiquid asset, to confirm accuracy of the digital representation and value of the asset, and generates an asset-information table indicating where the various sections of the digital representation are stored. The system also generates an asset-value token, financial-return tokens, and a data structure that includes a self-executing program. The program associates the asset-value token with the financial-return tokens, so that the illiquid asset becomes a collateral for a decentralized loan transaction implemented using blockchain technology. The use of blockchain technology for decentralized loan transactions enables immutable data traceability.

Abstract: A valve assembly for a tire inflation/deflation system includes a body having a control port and a tire port, and a valve member for fluidly connecting or disconnecting the control port with the tire port. In one embodiment, the valve includes a fluid-operated damper having a damper chamber for controlling a timing of the valve member. A vent valve is provided for permitting excess fluid pressure to escape from the damper chamber. In another embodiment, the valve member includes a diaphragm separating first and second fluid chambers. A vent passage and at least one resilient fluid pressure-operated valve element are provided for enabling fluid to vent from the first chamber to the second chamber. Multiple-redundant valve elements may be provided to form an isolation gap that restricts contamination of the valve assembly.

Abstract: A federated-data-room server manages information about a collection of electronic documents residing elsewhere (under different organizational/customer control). The server can anchor documents to a blockchain, record usage history of each document, and provide access to the documents for authorized users. As a result, the federated-data-room server operates on customers' data, while leaving the data in control of the customers. At the same time, the federated-data-room server provides data access and enables traceability via blockchain recordation of document identifiers and document hash values.

Abstract: A connector can be provided for attaching to a mobile electronic device which can have a cap portion, a protrusion extending distally from a bottom of the cap portion, the protrusion being configured to be attachable to an electronic port of a mobile electronic device. The cap portion can be configured to be sized and shaped so that, when the cap portion is attached to the mobile electronic device, the cap portion extends further in the distal direction along front and rear surfaces of the mobile electronic device than along a proximal surface of the mobile electronic device. A connector can be provided with a cap having a height and a width, the height of the cap being greater than the width of the cap, the cap having a proximal curved surface and a distal curved surface, and a protrusion extending distally from the cap, the protrusion being configured to be insertable within a port of the mobile electronic device such and to resist withdrawal from the port.

Abstract: Some embodiments described herein relate to a computer implemented method that includes receiving a token that includes a reference to a first encrypted archive recorded in a distributed ledger. The first encrypted archive can be decrypted using the token to retrieve a first manifest document, which can be associated with a first activity of the complex transaction. The first manifest document can identify a second encrypted archive. The second encrypted archive can be decrypted using the token to retrieve a second manifest document, which can be associated with a second activity of the complex transaction. The second manifest document can include a reference to a data product, which can be retrieved. A continuity of the complex transaction between the second activity and the first activity can be verified based on the data product.
