Abstract: A personal time management system includes a computer device having a display screen on which is generated a primary visual display comprised of individual event time bars and a composite conflict time bar. The event time bars graphically display times for scheduled events by means of visual markers occupying one or more slot times on selected time bars. The composite conflicts time bar simultaneously displays all the visual markers of the event time bars so as to provide a positive indication of a conflict. The visual markers representing scheduled events can readily be placed and removed directly on the primary visual display by one or two clicks of a mouse on a selected event time bar. Events can thereby be scheduled and rescheduled without the need to pull up and enter information on a secondary screen display.

Abstract: A facility is provided for greatly enhancing the rate at which volumetric data is processed by display on a two-dimensional display. Specifically, the volumetric data is first divided into a predetermined number of sub-blocks, in which a predetermined voxel in each sub-block is then transformed into an associated picture element. The sub-blocks and their associated pixels are then supplied to respective processors forming an array of processors. Each processor then completes the transformation of its sub-block as a function of the coordinates of the associated picture element and respective incremental vectors.

Abstract: A style of document format known as compound document architecture is known, in which a document is broken up into a tree of objects or segments (e.g. document: chapter: subtitle: para: para: etc.), possible with a second layout tree. Two styles of such architecture are ODA and CDA. Conversion from CDA to ODA presents difficulties, as in CDA, a segment can contain e.g. text and graphic elements, while ODA has stricter formatting rules. One of a plurality of DAPs (Document Application Profiles) 12 is selected, depending on which subset of full ODA is being used. The DAP contains a structure converter component which starts to construct the objects of the ODA document. When an information element is reached (text, graphics, etc.), it is sent to the appropriate one of a set of content handlers 13. These call back to callback units (text, graphics, footnote, etc.
