Abstract: Devices, systems, and methods of the present disclosure are directed to generating three-dimensional surface representations of an anatomic structure such as a heart cavity. More specifically, a three-dimensional surface representation of the anatomic structure is constrained relative to one or more anchor portions corresponding to received input regarding the location of anatomic features of the anatomic structure. The resulting three-dimensional surface representation includes salient features of the anatomic structure and, therefore, can be useful as visualization tool during any of various different medical procedures, including, for example, cardiac ablation.

Abstract: Systems and methods present multiple images of a three-dimensional model, including a three-dimensional representation of an anatomic structure and a representation of a medical device relative to the anatomic structure, on a graphical user interface. The multiple images correspond to different views (e.g., in multiple, different planes) of the three-dimensional model to provide complementary spatial information regarding a position of the medical device relative to the anatomic structure during a medical procedure performed on the anatomic structure. Such complementary spatial information can, for example, provide spatial context to facilitate controlling the position of the medical device relative to the anatomic structure during the medical procedure.

Abstract: Systems and methods of automatically controlling, on a graphical user interface used by a physician, display views of an anatomic structure of a patient. Such systems and methods of automatically controlling display views of an anatomic structure of a patient can facilitate visualizing a position of a medical device relative to the anatomic structure during a medical procedure directed to the anatomic structure. In certain implementations, the systems and methods of the present disclosure provide automatic display views of a cardiac catheter relative to a three-dimensional model of a patient's heart cavity during a medical procedure such as cardiac ablation.

Abstract: An ion electrospray device with a porous reservoir and at least one porous emitter includes a porous compliant interface sandwiched between the porous reservoir and the porous emitter for transferring fluid from the porous reservoir to the porous emitter. The interface has a characteristic capillary pressure stronger than the characteristic capillary pressure of the porous reservoir to fill the porous emitter with fluid via a fluid injection section of the interface and before the porous reservoir is then partially filled with fluid. Emitter leakage and propellant bridging problems are addressed.

Abstract: A device may participate in a shared data state in which editing operations performed locally are distributed and synchronized with other devices participating in the shared data state. Data may be maintained in log-structured storage files on each device. Changes made locally may be represented by change descriptors conditionally appended to the end of a log. The size of the log may be monotonically increasing. Monotonically increasing identifiers may be used to implicitly or explicitly identify change descriptors. Upon conflict resolution, conditionally appended change descriptors may be committed. Non-committed change descriptors may be conditionally reappended to the end of the log for further conflict resolution.

Abstract: A device may participate in a shared data state in which editing operations performed locally are distributed and synchronized with other devices participating in the shared data state. Data may be maintained in log-structured storage files on each device. Changes made locally may be conditionally appended to log-structured storage and committed or rolled back during synchronization. Sets of related change descriptors may be identified based on inferred user intent. Conflict resolution rules may be applied to sets of related change descriptors. Conflicts may be resolved through application of conflict resolution rules or through a user-involved process.

Abstract: A multidimensional sound system coordinates the playback of audio streams on a device that outputs more than one video stream simultaneously. The system provides a method for splitting and directing sound so that multiple users viewing multiple content streams on a single device can hear audio relevant to the video content they wish to view. The system also provides methods directed to allowing users to share audio relevant to their respective video streams with other users on the same device, and allows users to reject such sharing requests.

Abstract: A child-safe, hand, fruit corer and slicer includes: handle, a wire member having two ends and a configuration between these ends that is adapted to: (a) provide the outline of: (i) a triangular-shaped structure that has three corners and a base that is situated approximately perpendicular to the handle's centerline, and (ii) a wing-like structure that extends perpendicular to the handle's centerline from each of the corners of the base of the structure, (b) enable the triangular-shaped structure to penetrate a fruit that is to be cored and sliced, and by the at least 180 degree rotation of the handle to core out a core section of the fruit, and (c) enable this wing-like structure to penetrate and slice the fruit into two halves when the handle is moved forward along the handle's centerline.

Abstract: A graphical production system produces pixel bar charts, in various embodiments. In an embodiment, a pixel bar chart is constructed that may include multiple bars with substantially equal widths and potentially variable heights to enable visual data analysis. A bar may include a number of pixel units corresponding to a volume of data records represented within the bar. Selected visual indicators are displayed within the pixel units of the bar, where a selected visual indicator represents a value of an attribute of a data record represented by the pixel unit. In an embodiment, the pixel units may be ordered within a bar in a particular sequence (e.g., ascending, descending or some other order). Further, in an embodiment, the bar width is determined to minimize the amount of padding. In an embodiment, a visual indicator scale is displayed to indicate values associated with each visual indicator.
