  • Publication number: 20250225319
    Abstract: Document difference viewing and navigation are disclosed that enables automatic comparison and easy viewing of the difference between many documents (e.g., four or more, dozens, hundreds, or thousands of documents) for, for example, document review processes. The system obtains and reads a set of documents containing text. The system identifies shared text and differences by location within the shared text among different documents in the set of documents. It sorts the documents in the set of documents into groups of different text variation versions and generates a shared difference document. The shared difference document is displayed in a first panel of a user interface and displays shared text as static text and areas of difference in highlighted regions. When a user selects of a given area of difference, the text variations and a list of documents containing one or more corresponding text variations are displayed in a second panel.

  • Publication number: 20240386418
    Abstract: Methods, systems, and devices for using a blockchain wallet for two-factor authentication are described. A custodial token platform implements a two-factor authentication process using a wallet to facilitate verifying a user identity accessing an application or service. The platform receives, from a client application on a user device, an authentication request that is associated with a first user account. The platform transmits a response indicating that a wallet authentication procedure is enabled and the response may include a wallet address. The platform receives a challenge request that includes the wallet address. The platform transmits a challenge response that includes a data payload to be signed using a private key associated with the wallet address. The platform receives a signed response message. The platform verifies that the signed response message is validly signed, and the platform transmits an indication that the signed response message is validly signed.

  • Patent number: 11933087
    Abstract: A storage console includes a housing with a storage chamber, two closure members connected to the housing, an actuator movably arranged in the housing and a latch mechanism rotatably connected to the housing. The two closure members can be rotated to open or close the storage chamber. The latch mechanism includes two latch members and a synchronizer connected between the two latch members. The movement of the actuator actuates the two latch members to rotate to a lock position in which the two latch members engage with the two closure members or a release position in which the two latch members are separated from the two closure members. The two closure members of the storage console can be opened synchronously by use of the actuator and closed independently of each other.

  • Publication number: 20240079808
    Abstract: An electrical connector includes a body having a terminal installation position for installing a terminal, a first connecting part, an accommodating cavity, and an insertion slot, a cover having a second connecting part, and an elastic support fixed in the accommodating cavity. The cover is movably connected to the body by the first connecting part and the second connecting part. The elastic support has a first elastic arm and a second elastic arm. The first elastic arm supports the cover. The second elastic arm has a snap-fit part locking an external insert inserted into the insertion slot at a preset position. The cover is movable relative to the body to have the second connecting part press and elastically deform the second elastic arm, driving the snap-fit part to move and unlock the external insert.

  • Publication number: 20230073193
    Abstract: The present invention provides a connecting terminal for connecting a wire, including: a body; a clip portion extending from both sides of the body and configured to hold a conductor of a wire; and a fixing part extending from both sides of the body, including: a clamping part configured to clamp an insulating layer of the wire; and a stopping part formed on the clamping part and configured to abut the terminal position assurance device to enable the connecting terminal to be fixed in the housing when the connecting terminal is mounted in the housing of the connecting assembly. Since the fixing part has both a clamping part for clamping the wire and a stopping part forming an appropriate height difference with the wire, the connecting terminal provided by the present invention becomes more compact and miniaturized.

  • Publication number: 20210179246
    Abstract: Aspects of the technology include an automated system for launching lighter-than-air high altitude platforms (HAPs), in particular balloon-type HAPs. A launch system and process are employed that use cameras to observe balloon sway and other factors. A control system detects the angle and position of the balloon gas bubble in relation to the payload in real time in view of wind and other environmental factors. This, in turn, enables the control system to automatically actuate the release mechanism and launch the balloon system at a selected point in time. This mitigates issues that can occur with manual operator-controlled launches, and increases the likelihood of a successful HAP deployment in the stratosphere. Models created via machine learning enable the system to determine criteria indicating a likelihood of a successful launch. These models may be sued by the control system in order to select an appropriate point for launching the platform.
