Abstract: A document preview system provides previews of a native document to client devices. The previews include comments associated with native objects in the native document. The document preview system identifies bounding areas in the preview associated with the native objects, which may be identified by the rendering markers applied to the native document prior to rendering. Using the bounding areas, the document preview system identifies comments for the native document and determines the location to display the comment using native objects associated with the comment. When a new comment is received from a user for a preview of a native document, the document preview system determines native objects for the new comment that match a user's selection for placing the new comment. The new comment is inserted with the native objects in the native document.

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.

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.

Abstract: Various embodiments of a balloon catheter and related methods are disclosed. In particular, one exemplary embodiment of a balloon catheter may include a balloon having an inlet opening for receiving inflation fluid and a one-way valve disposed in the inlet opening to allow inflow of the inflation fluid into the balloon while substantially preventing backflow of the inflation fluid from the balloon. The catheter may also include an elongated shaft comprising a proximal end, a distal end, and a lumen extending between the proximal and distal ends. The shaft may be configured to supply the inflation fluid to the balloon through the lumen and to releasably couple the balloon to the distal end of the shaft.

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.
