  • Publication number: 20160206457
    Abstract: Feedback systems and methods enhance obstructive and other obesity treatments by presenting feedback regarding patients' actual eating. An ingestion restricting implant body can be deployed along the gastrointestinal tract. In some embodiments, ingestion alters the implant body, which, in turn, generates signals. The generated signals can be used to inhibit unhealthy ingestion by the patient. In other embodiments, the implant body can be altered by signals so as to selectable change the restriction imposed on the gastrointestinal tract, optionally in response to ingestion events, an eating schedule, or the like. The implant body may comprise a gastric band. Sensor signals may be processed to identify ingestion and/or characterize ingestion material, and the results may be displayed on a screen for a patient or coach to view.

    Abstract: There is disclosed apparatus and methods of multicasting in a shared address space. A shared memory address space may include two or more multicast portions. Each multicast portion may be associated with a respective end point and with at least one other multicast portion. Data units may be transmitted to at least some of the end points via memory-mapped I/O into the shared memory address space. When a destination address of a data unit is in a first multicast portion associated with a first end point, the data unit may be transmitted to the first end point, revised to specify a destination address in a second multicast portion associated with the first multicast portion, and transmitted to a second end point associated with the second multicast portion.

    Abstract: Various embodiments of systems and methods for extrapolating tabular structure to facilitate manipulation of elements in the freeform document are described herein. The freeform document includes an unstructured canvas providing users the ability to place one or more elements in the canvas. A primary column is determined by the selection of at least one element in the freeform document. Further, one or more secondary columns in the freeform document corresponding to the primary column are determined. A tabular structure in the freeform document is extrapolated based on the determined primary column and the one or more secondary columns to facilitate manipulation of elements in the freeform document, such as reordering, resizing and deleting the one or more elements, and inserting one or more new elements in the freeform document.
