Abstract: A unidirectional clutch device for an electric nail gun, comprising a motor, an annular gear fixed above the motor, and a clutch seat. The annular gear contains a central gear and planetary gears. The central gear forms a transmission connection with the motor and meshes with the annular gear through the planetary gears. A lower shim is fixedly attached to the lower part of the annular gear, and an upper shim is positioned at the upper part of the annular gear, movably abutting between the annular gear and the clutch seat. The upper shim has through holes for the pins of the planetary gears. Inside the clutch seat, there is a planet carrier with a cylindrical outer surface, machined with mounting holes for the assembly of the pins. The internal circumference of the clutch seat is machined with needle roller grooves containing needle roller pins.

Abstract: A digital content management system may include a set of one or more memory components and a set of one or more processing devices coupled to the set of one or more memory components. The set of one or more processing devices to perform operations comprising: obtaining one or more electronic signatures on a digital document to yield an electronically signed digital document, storing the electronically signed digital document at an off-chain address, using a trained machine learning model to create a smart contract, the smart contract comprising a reference to the off-chain address; and deploying the smart contract to a blockchain.

Abstract: A safety frame travel adjustment device for a nail gun, comprising a firing plate. The safety frame has a long slot machined into it. A positioning sleeve is fixed to the side of the firing plate and interacts with the long slot to ensure the safety frame can slide along the direction of the firing plate. Also on the side of the firing plate is a first spring that supports the safety frame. Additionally, an adjustment seat is fixed to the side of the firing plate, housing an adjustment component for modifying the position of the safety frame. This adjustment component consists of a connecting bolt, a threaded sleeve, an adjustment wheel, and an opening and closing rod. The connecting bolt is secured to the safety frame with a locking nut and is threadedly connected to the threaded sleeve.

Abstract: A method for controlling movement of a cursor on an electronic device, a mobile device, and. an electronic device are provided.

Abstract: An optical waveguide includes a cladding layer, a Si layer, a REO layer, and a cap layer. The REO layer is made of a single-crystal rare earth oxide, and is formed on the Si layer. The cap layer is formed on the REO layer. The cap layer may be made of a material transparent to light to be guided. The cap layer has a stripe shape extending in a direction in which light is guided.

Abstract: A mobile device communicates wirelessly with an annotation device and a to-be-annotated electronic device. The mobile device includes a processor, a memory, a UWB tag, a direction sensor, and a computer program stored in the memory, and when the computer program executed by the processor, the mobile device is enabled to perform: receiving a first input after the mobile device moves to a location of the electronic device; recording a location of the mobile device in response to the first input, where the location of the mobile device is the location of the electronic device; and popping up a first control window for the electronic device after the mobile device moves to another location and points to the electronic device. According to this application, the mobile device can control, by using the annotation device, an electronic device on which no UWB chip is installed.

Abstract: The disclosure provides a naphthylurea compound having a formula I. In the formula, m and n represent a number of CH2, and are an integer from 1 to 10; k and z represent a number of CH2, and are an integer from 0 to 6; and p represents a number of CH2, and is 1, 2 or 3; and X is O or S.

Abstract: A licensing system and related methods are described utilizing aspects of distributed ledger technologies to facilitate trusted and verifiable licensing transactions for creative works. A client device can include an asset editing tool for incorporating an asset selected from a plurality of licensable assets into a new creative work. The selected asset can be downloaded for incorporation into the new creative work. The new creative work incorporating the selected asset can be analyzed to determine an amount that the selected asset contributed to the new creative work, or an amount that the new creative work is attributable to the selected asset.

Abstract: The disclosure provides a naphthylurea compound having a formula I. R represents H, a C1-C5 straight-chain alkyl, a C1-C5 straight-chain alkyl with a halogen-substituted end or a 5-8-membered cycloalkyl; R1, R2, R3, R4, R5, R6, R7, R8, R9 at each occurrence represent H, F, Cl, Br, —CN, —CH3, —CF3, —OCH3, or —OCF3; R5 optionally represents phenyl, and M is H or —CH3; m represents a number of CH2, and is 0 or 1; n represents a number of CH2, and is 1, 2, 3, or 4; and p represents a number of CH2, and is 2; and X is O or S.

Abstract: Embodiments provide traceability of edits to a document, i.e., a verifiable and immutable provenance chain for the document. Systems and methods enable traceability of edits, by encoding, for states of the document, a fingerprint (e.g., a cryptographic hash of the document's contents) and an edit history within a block written to a distributed ledger (e.g., a blockchain). The ledger is maintained via a self-organizing peer-to-peer distributed ledger network. Once added to the ledger, the contents of a block (e.g., the document's fingerprint and edit history) are immutable and the integrity of the edit history encoded in the ledger is secure. The algorithm that generates the fingerprint is sensitive to edits of the document. The non-corruptible fingerprint encoded in the ledger is employable to detect any edits that are not included in the encoded edit history and/or inconsistent with a currently available version of the document.

Abstract: The present disclosure provides synthetic collagen and methods of making and using synthetic collagen that include a synthetic collagen that facilitates wound closure comprising an isolated and purified triple helical backbone protein that facilitates wound closure comprising one or more alteration in a triple helical backbone protein sequence, that stabilize the isolated and purified triple helical backbone protein and does not disrupt an additional collagen ligand interaction; and one or more integrin binding motifs, wherein the isolated and purified triple helical backbone protein facilitates wound closure.

Abstract: Embodiments relate to a smart contract platform that facilitates creation, execution and verification of customized smart contracts. The smart contract platform enables design of customized smart contracts for execution and verification on a distributed ledger network, including smart contracts with logic for querying and fetching sensitive transactional data from participant nodes. A distributed ledger can store tokens indicating successful completion of one or more transaction elements without making some or all the associated transactional data visible. A smart contract form viewer can be used to view and interact with a smart contract form linked to the smart contract. The smart contract form can present contractual provisions in natural language, present transactional data to an authorized user, and accept entry or validation of designated transaction data.

Abstract: Embodiments of the present invention provide systems, methods, and computer storage media directed to a proof and attestation service that can confirm the veracity of a claim or a statement of truth based on data dynamically-retrieved from various data repositories. A server device receives, from a client device, a request to determine the veracity of a claim or a statement of truth. The server device is generally a trusted computing device, having privileged-access to a variety of data repositories that the client device may or may not access. The server device can select one or more data repositories based on the claim, obtain results data from the selected one or more data repositories, and evaluate each result to determine whether it corresponds to or contradicts the claim. A veracity score can be calculated for the claim or for a result that corresponds to or contradicts the claim.
