  • Patent number: 11429634
    Abstract: In some embodiments, an interface of a content management system manages synchronized content on storage systems. For example, the interface stores, on a metadata storage structure, records of metadata associated with blocks of data stored on a storage, the records including block identifiers that uniquely identify the blocks and timestamps associated with the blocks. The interface identifies a batch of storage operations associated with the blocks, including one or more delete operations. For each delete operation, the interface queries the metadata storage structure for a timestamp corresponding to a block of data associated with the delete operation, determines whether the delete operation creates a race condition between the delete operation and an add operation associated with the block of data, and rejects the delete operation when the delete operation creates the race condition or the timestamp corresponding to the block of data is newer than a predetermined period of time.

  • Publication number: 20220231534
    Abstract: A method for ensuring emergency operation of an actuator of a motor vehicle in the event of failure of an electrical supply line for a control unit of the actuator includes supplying at least one driver for the actuator with electrical voltage by a capacitor. The capacitor may be charged from an energy store of the motor vehicle or kept in a charged state during normal operation. A logic module of the control unit may undergo a reset in order to trigger the emergency operation.

  • Publication number: 20210182311
    Abstract: An interface of a content management system manages storage and access of content on the system. For example, after receiving, from a client, a request to download a content item, the interface determines whether the request includes a valid token. If so, the interface sends a content item request to a storage service, retrieves the content item, and sends the content item to the client. Otherwise, the interface sends an authorization request to an authorization service, an authentication request to an authentication service, and a content item request to the storage service. Based on the requests, the interface determines whether the content item is available in storage and whether the client is authorized to access the content item. When the content item is available in storage and the client is authorized to access the content item, the interface retrieves the content item and sends the content item to the client.

  • Patent number: 10701374
    Abstract: Techniques for image recompression. In one implementation, the techniques are implemented to recompress a baseline joint photographic experts group (JPEG) image with compression savings. The techniques replace the Huffman coding of baseline JPEG with an arithmetic coding that uses a sophisticated adaptive probability model. The arithmetic coding techniques avoid global operations such as global sorting that would prevent distributed and multithreaded decompression operations when recovering the original JPEG image from the recompressed image. At the same time, the techniques realize substantial compression savings relative to baseline JPEG, on average 23% compressing savings in some implementations.

  • Patent number: 10572573
    Abstract: A document preview system provides previews of a native document to client devices. To generate the preview of a document, the document preview system generates a preview document that presents the native document in a browser-compatible format including elements that correspond to fields in the native document. The document preview system also identifies a mapping between fields of the native document and the elements of the preview. The document preview system also identifies a formula listing for the elements of the preview code. When a user edits a document, the edits may be committed to the document preview system and in parallel generate a preview to update the user's display. When an updated preview is available, the updated preview is rendered in a hidden frame and the user's input context is captured and reproduced when the updated preview replaces the prior preview.

  • Patent number: 10258770
    Abstract: A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space. The catheter includes an inflatable balloon mounted on a distal end region of the catheter shaft of the catheter. The catheter shaft includes a guidewire lumen having a distal opening and a lateral opening in a distal region of the catheter shaft proximal of the distal opening, and an inflation lumen in fluid communication with the balloon. The balloon is configured to be inflated in the subintimal space to a first inflation state at inflation pressures below a threshold inflation pressure to orient the lateral opening toward the lumen of the blood vessel, and inflated to a second inflation state at inflation pressures above the threshold inflation pressure. The catheter includes means for retaining the balloon in the first inflation state at pressures below the threshold inflation pressure.
