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 allows for account recovery even while maintaining non-custodial ownership of the wallet.

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.

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.

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.

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.

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.

Abstract: A method and appertaining system for implementing the method are provided that utilize predefined Best Practice Templates that are rules/criteria for assessing the security of a particular network and devices on the network. A value is determined for each object and connection within a network as to whether it passes or fails one of the Best Practice criteria, and a pass ratio is determined for a particular Best Practice. Numerous Best Practice tests may be run, and an overall total value based on the collective sum of the Best Practice measurements is determined. This value can be utilized to provide a user with information that relates to the overall security of a network and can be used in compliance determinations and network architecture design.

Abstract: A scent notification system operably coupled to a conventional cellular phone wherein the scent notification system is configured to alert the cellular phone user to an incoming communication via dispersal of a fluid having a specific aromatic property. The scent notification system further includes a housing that is operably coupled to the cellular phone. The housing has an interior volume that has contained therein at least one cartridge containing a fluid and an expansion chamber operably coupled thereto. The cartridge further includes a propellant to propel the fluid from the cartridge to the expansion chamber where the fluid converts to a gaseous phase and then propagates out of the expansion chamber via a nozzle.

Abstract: Documents are grouped into a plurality of subjects. For documents associated with each subject, a document hierarchy is established that includes a plurality of hierarchical levels. A three-dimensional landscape defined by x, y and z orthogonal axes is displayed on a screen, and a plurality of document stacks are arranged in the landscape. Each document stack in the landscape corresponds to a subject, and has a plurality of layers arranged perpendicular to the length of the stack. Each layer in each document stack corresponds to one of the hierarchical levels of the hierarchy established for the subject corresponding to the stack. Images representing documents assigned to each level of the hierarchy are displayed in the layer of the stack corresponding to such level. A user navigates among the document images displayed in the landscape using a cursor.
