Abstract: The disclosure provides a cranial access device that reduces or eliminates artifacts during imaging. The cranial access device includes a cranial bolt and a drive adapter. The cranial bolt includes a distal threaded portion, a proximal drive portion comprising a plurality of protrusions that form an external drive geometry, and a central passageway configured for receiving a neurosurgical tool. The drive adapter includes a distal end configured to receive and interface with the external drive geometry of the proximal drive portion, and a proximal end configured to receive a driver tool.

Abstract: Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed. An example method may control operation of a pump of pump/filtration system to facilitate removing cerebrospinal fluid from a patient, filtering the cerebrospinal fluid with a filter module to remove waste product, and returning the filtered cerebrospinal fluid to the patient. Operation of the pump may be adjusted based on a value related to a measure sensed by a sensor in communication with a lumen carrying cerebrospinal fluid through the filtration system.

Abstract: A method and computer graphics program executed by one or more processors is described for arranging regions which refer to various parts of a graphical layout such that changes to the original layout result in updates to the said regions. The regions themselves may be arranged by the user in patterns for various purposes, such as condensing graphical content spread over many parts of the original layout into a single output page in order to minimize the consumption of ink and paper when printing.

Abstract: A method and system for automatically producing arrangements of two-dimensional extents in a computer-based editing or animation environment is presented. The method consists of defining a set of objects having two or more dimensions automatically calculating and presenting an arrangement of send objects, and optionally iterating to produce alternative arrangements. The arrangements may use templates to guide the selection of sizes, border colors and transparency, rotation, and other attributes of the contained regions.

Abstract: A user may position a graphic object in a layout and the computer automatically knocks out frames to accommodate it. In implementation, a panel or panel set also may allow occluded or overlapping frames to be knocked out automatically in response to a user positioning an object in the layout in the graphical user interface. The computer determines from the size, position and orientation of the object which frames in a panel are overlapping or occluded, marks them as knocked out, and rearranges objects in the panel. As a result, the other images on the page appear to flow around the occluding or overlapping frame. Any textual labels or other information displayed for the occluded or overlapping frames also can be suppressed. A user can overlay as many occluding or overlapping objects as desired over a panel.

Abstract: A method and computer graphics program executed by a processor for interactively subdividing a region in a computer controlled graphics display system is described. The user directly manipulates a control object (or “handle”) using a pointing device such as a computer mouse with the result that the region exposing the control object is evenly divided into an array or volume of smaller regions. The distance from the position of the start of interaction with the control object (the “click”) is continuously monitored to interactively update the number of divisions in the horizontal and vertical directions. Example displays during this interaction phase include overlaid grids representing the actual position of pending subdivisions, or a matrix of abstract subregions representing the count of subregions that will be created when the user indicates that the interaction is complete by releasing the control object.

Abstract: A method and computer program executed by a processor is described for visually distributing a multiplicity of data objects within a visual computing environment. The user directly manipulates a cursor using a pointing device such as a computer mouse to sequentially indicate where a plurality of objects are to be positioned: these objects are presented as visual controls attached to the cursor, providing feedback as to the identification, order, and number of objects to be distributed. As the user indicates the desire to place the next-to-be dropped object (for example by clicking a button on the computer mouse), that object is dropped at the current cursor position, the representation of that object removed from the set of visual controls attached to the cursor, and the subsequent objects to be dropped advanced by one. The user may optionally re-order the objects to be dropped prior to actually dropping them, and may optionally exit and return to the dropping mode at any time.

Abstract: A system has a hierarchical organization for modifying and applying tools for manipulating data types. The system has a user interface for displaying the hierarchical organization, an inspector for viewing and modifying an internal structure of the tools and a button for launching each of the inspectors.

Abstract: A user interface receives user input representative of movement of a mouse pointer relative to a datum point. This datum point is established as a origin with four quadrants. The movement is determined to be either in a first sense or an opposite second sense relative to the datum point. A variable responsively increments when the movement is in the first sense and responsively decrements when the movement is in the second opposite sense. The user may move the pointer in a generally circular or spiral pattern in a clockwise or counterclockwise sense about the origin until the desired value is attained.
