  • Publication number: 20240062203
    Abstract: A method for executing a transaction on a blockchain or other distributed ledger that reduces transaction gas fees. A backend server estimates gas fees based on recent successful transactions and obtains user approval before submitting the transaction to blockchain.

  • Publication number: 20240062204
    Abstract: A method for executing a transaction on a blockchain or other distributed ledger that protects the user from other blockchain users attempting to front run or rerun an approved transaction. A backend server searches the blockchain for existing transactions that use the same approval.

  • Publication number: 20240062189
    Abstract: A method for executing a transaction on a blockchain or other distributed ledger that enables a user holding only non-native tokens to execute the transaction. A backend wallet managed by a backend server maintains different native token types for different blockchain types and is used to execute the transaction on behalf of the user. The backend server then reconciles the cost with the user's own wallet.

  • Publication number: 20240062192
    Abstract: A method for using metadata to consolidate two transactions into one to execute a smart contract as a single transaction on a blockchain or other distributed ledger. Compared to the previous two-step smart contract execution process, this one-tap process (such as for staking an amount to a pool) allows specifying a predefined amount to execute instead of an exploitable infinite amount.

  • Patent number: 11907936
    Abstract: A method for securing a split private key (such as used with a cryptocurrency or other non-custodial electronic wallet) amongst a password, biometrics, and a social service. The process may use a sharding scheme such as Shamir's Secret Sharing to ensure that multiple key shards must be obtained before the entire private key can be obtained. The user may select the number of shards required to retrieve the private key thereby controlling the security of the account. An additional shard may be held on an encrypted server and allows for account recovery even while maintaining non-custodial ownership of the wallet.

  • Publication number: 20230160665
    Abstract: Ballistic resistant composite materials having high positive buoyancy in water are provided. More particularly, provided are foam-free, buoyant composite materials fabricated using dry processing techniques. The materials comprise fibrous plies that are partially coated with a particulate binder that is thermopressed to transform a portion of the binder into raised, discontinuous patches bonded to fiber/tape surfaces, while another portion of the particulate binder remains on the fibers/tapes as unmelted particles. The presence of the unmelted binder particles maintains empty spaces within the composite to materials which increases the positive buoyancy of the composites in water.

  • Patent number: 11585447
    Abstract: A valve seat for a ball valve. The valve seat having a valve seat body with a circumferential concave seating surface configured to mate with a curvature of the valve ball. A seal pocket formed within the valve seat body, the seal pocket having (i) an throat formed in the concave seating surface, (ii) an outer pocket sidewall, and (iii) an inner pocket sidewall. A retaining groove positioned below the throat on either the outer pocket sidewall or the inner pocket sidewall and a flexible seal element shaped for positioning in the seal pocket. The seal element includes (i) an extended lip configured to rest within the retaining groove when the seal element is seated in the seal pocket, and (ii) a sealing face with an upper end laying below the valve seat's concave seating surface and a mid-portion extending upward above a curvature path of the concave seating surface.

  • Patent number: 11530513
    Abstract: A method for improving the translation efficiency of fiber strength into composite strength is provided. A single unidirectional tape, single unidirectional fiber web or a stack of unidirectional web/unidirectional tape plies formed from partially oriented fibers/tapes is primed under mild conditions followed by subjecting the primed plies to an axial extension stress in the axial fiber direction of each fiber ply by passage through a compression apparatus. The axial extension stress extends the fibers, strengthening them, while also compacting the plies together and thereby forming a composite having improved strength. Production yield is improved by avoiding maximal fiber stretching and thereby avoiding typical manufacturing loss, and low weight composite armor having increased strength is achieved.

  • Patent number: 11440287
    Abstract: Multi-ply, hybrid composite materials useful in the formation of thin walled, hollow, tubular articles having improved resistance to hoop stress. Two different, single-ply pre-pregs are impregnated with binders and laminated together with the fibers of the layers oriented at a bias relative to each other. The hybrid composite is rolled into a tubular article having excellent strength uniformity along the full length of the tubular article.

  • Patent number: 11027501
    Abstract: Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature.

  • Patent number: 10704866
    Abstract: Viscoelastic, lightweight composite armor that is resistant to backface deformation, and to a method for evaluating the effectiveness of composite armor in resisting backface deformation. The index of retraction of a composite is determined by evaluating the degree of composite retraction at the site of impact of projectile after movement of the projectile is stopped. The degree of retraction indicates the ability of the composite to resist backface deformation.
