Abstract: A method includes assigning, to first voxels in a model of tissue of a chamber of a heart, respective first values of a parameter at respective locations on the tissue, the first voxels representing the locations, respectively. Some of the locations are on an endocardial surface of the tissue, and others of the locations are on an epicardial surface of the tissue. The method further includes assigning respective second values to second voxels in the model, a subset of which represent a portion of the tissue between the endocardial surface and the epicardial surface, by interpolating the first values. Other embodiments are also described.

Abstract: A method includes receiving or generating a volume map of at least a portion of a cavity of an organ of a body including a plurality of mapped locations, and a point cloud of locations in the cavity marked for treatment. The volume map is updated by removing a portion of the mapped locations, so that the locations marked for treatment fall on a surface of the volume map. Using the updated volume map, a map of at least a portion of the cavity is generated, the map including the locations marked for treatment. The map is displayed to user.

Abstract: A system includes a display and a processor. The processor is configured to: (i) receive a dataset including multiple data points, each data point corresponding to one or more properties of an organ of a patient, (ii) produce, based on a clustering criterion, at least a cluster including two or more of the data points, and (iii) produce and present on the display, a map of the organ and at least an object indicative of the cluster. In response to selection of the object by a user, the processor is configured to produce and present on the display, a two-dimensional (2D) table including the one or more properties of each of the clustered data points.

Abstract: An electronic utility device is provided. The device includes a user input interface and a user output interface, the user output interface including a compact virtual display for providing visual information to the user, the compact virtual display including (a) a light-transmissive substrate; (b) an input diffractive optical element integrally formed with the light-transmissive substrate; (c) an output diffractive optical element integrally formed with the light-transmissive substrate laterally of the input diffractive optical element; and (d) an image source for producing a real image, the image source optically communicating with the input diffractive optical element so as to collimate the real image into plane waves transmittable along an optical path through the light-transmissive substrate, such that when the plane waves impinges on the output diffractive optical element the plane waves are focused to form a virtual image which correspond to the real image and which is viewable by the user.

Abstract: This invention provides a combined bed and wheelchair wherein the bed frame and any mattress thereon have a cut-out extending from the foot end thereof. An insert having a head section, a center section and a foot section which are normally aligned in a common plane is adapted to fit in and substantially fill the cut-out. The sections are hingedly connected together with the insert being automatically transformable into a chair as the insert is removed from the frame. Wheels are connected to at least one section of the insert to permit the insert to be rolled and removed from the frame. The automatic transformation is preferably performed through the operation of first and second coacting elements mounted, respectively, to the frame and insert.

Abstract: A flowmeter for the quantitative measurement of small rates of flow of fluids (liquids and gases), comprising a hermetically sealed housing having two parallel walls, at least one of these being transparent, a scale being provided on said transparent wall, a thin flexible resilient vane attached by one of its ends to a sidewall of the housing so as to divide the inner space into two parts, inlet means for the fluid being provided in sidewall connected to one of these parts, outlet means being provided in a sidewall of the other part, the flexible vane having an area protruding into the inner space of the housing equal to essentially the inner cross-section of the housing at the position of the vane when no fluid is flowing. Preferred shapes of the housing are (in side view) a semi-circle, half an ellipse or a triangle.
