Abstract: Cryogenic sources can be used for shielding in wire-based additive manufacturing. Cryogenic shielding can provide better shielding during print, as well as more efficient cooling compared to using regular room temperature shielding gas. Cryogenic shielding can extend the nozzle run time by preventing spatter build up in nozzles. Cryogenic sources also can be used for active part cooling and/or active weld puddle cooling.

A device may initiate a pilot arc between a plasma electrode and a grounded portion of a torch assembly, the grounded portion of the torch assembly grounded using a component with a variable resistance. A device may initiate a wire arc between a first wire element and the workpiece. A device may add material to the workpiece while the torch assembly traverses the workpiece.

Abstract: A linear escapement mechanism is provided for actuating a downhole tool in a controlled and predictable manner, such as in response to a certain number of pressure cycles. In an example, the actuator includes an escapement sleeve axially moveable with respect to an actuator housing. The escapement sleeve has a plurality of axially-arranged escapement teeth. A rocker secured within the actuator housing has opposing first and second pallets. An operating sleeve is reciprocable to rock the rocker back and forth to alternately move the opposing first and second pallets into engagement with the escapement sleeve as the escapement sleeve advances axially in an actuating direction.

Abstract: Systems, methods, and graphical user interfaces (GUIs) for ingesting and enriching data regarding a plurality of entities are provided. A first data set comprising company data and a second data set comprising customer data are ingested. The first data set is processed to generate a processed data set. The first data set may be processed by applying an entity matching technique, wherein one or more data elements are generated based on whether an entity of the first data set and an entity of the second data set are commonly associated. The first data set may additionally or alternatively be processed by applying a statistical matching technique, wherein one or more predicted data elements are generated based on similarity between an entity of the first data set and one or more entities of the second data set.

Abstract: In some examples, a system is to receive, from a client device, a query comprising a representation of blockchain information of an entity associated with an electronic device that advertised the representation. The system is to further determine whether a client entity associated with the client device has a privilege to access response information that is responsive to the query, and in response to determining that the client entity has the privilege to access the response information, send, to a blockchain network, a request containing the blockchain information to obtain the response information.

Abstract: Systems and methods for localized work return path of additive manufacturing systems are described. Localized grounding connects the printed surface directly to the work return, and shortens the length of grounding and/or the return cables compared to substrate-based grounding.

Abstract: A method of removing phosphates from water in a continuous process, the method comprising the steps of: (a) passing the water through a first zone in which the pH is adjusted; and (b) passing the water through a second zone in which the water is contacted with magnesium ions; wherein the water is contacted with ammonia in the first zone and/or in the second zone.

Abstract: Examples described herein relate to integrating a blockchain-enabled reader with a blockchain network over machine-to-machine communication protocol. A subscriber node may receive event data published by a publisher node. The event data may be communicated to the publisher node from a blockchain-enabled reader using a machine-to-machine communication protocol. The event data may be attested by the blockchain-enabled reader using a decentralized identity provisioned to the blockchain-enabled reader from the blockchain network. The decentralized identity of the blockchain-enabled reader may be verified. The event data may be submitted by the subscriber node to a distributed ledger upon successful verification of the decentralized identity of the blockchain-enabled reader.

Abstract: A computerized method for performing work-flow drilling operation management for offshore drilling operations. In a planning phase, the planner creates digital work instructions in the software tool and shares these digital work instructions for the offshore drilling operations with one or more reviewers for approval.

Abstract: Techniques are described for user account matching based on natural language utterances. In an example, a computer system receives a set of words, a voice print, and offer data about an offer based at least in part on a natural language utterance at a user device. The computer system determines a set of user accounts based at least in part on the set of words and determines, from this set, a first user account based at least in part on the voice print. The first user account is associated with a first user identifier. The computer system determines that the offer is associated with a second user account that is further associated with a second user identifier. The computer system generates associations of the user accounts with user identifiers and with the offer.

Abstract: A weight support device includes a sensor grid that measures pressure data while a user is on the weight support device. The weight support device is connected to a computer that analyzes the pressure data and generates a virtual figure to represent the user. Based on the pressure data, the computer determines how the user moves and adjusts relative positions of segments in the virtual figure that represent various body parts corresponding to the movements of the user. The relative positions of the segments may be determined based on a kinematic model. The virtual figure is presented on a display (e.g., in a video) to illustrate how the user moved.

Abstract: In some examples, in response to a request from a client device for information relating to a transaction stored by a blockchain, a system identifies, using information stored in a distributed storage system that stores data for the blockchain, multiple data owner entities from which permissions are to be obtained for access of the information, and determines an authorization requirement for the information based on a smart contract. The system sends authorization information based on the authorization requirement to trigger a retrieval of authorization tokens from the identified data owner entities for access of the information, and sends the information to the client device in response to receiving the authorization tokens.
