    摘要： An apparatus is described which includes memory areas for storing an image and trigger fields for the image, and a display which indicates a cursor in one of two configurations. Circuitry is provided for moving the cursor and enabling it to implement a select operation for a particular subroutine. The apparatus employs a method which enables the trigger fields to be invisible, which method comprises: displaying the image without trigger fields; and altering the cursor on the display from one configuration to another upon the cursor being moved into an invisible trigger field to thereby indicate to the user the presence of the trigger field.

    摘要： A display apparatus is described having the capability to pan a viewport image across a world-plane image. The viewport image has defined boundaries and exhibits a cursor whose position is movable by a user operated mouse or keyboard controls. The invention comprises a method for providing a variable-rate pan action of the viewport image which includes panning the viewport image at a preset rate in the direction of a first viewport boundary, if the cursor has been moved to the first boundary. The viewport image is panned at a proportionally faster rate in the direction of the first viewport boundary, as the cursor is moved further beyond the first viewport boundary thus enabling a variable speed pan under user control.

    摘要： A graphic display PC/interface system is described which includes three memory units: a source memory which is addressed in planar byte increments and stores display data units on a bit per plane basis; a target memory for storing display data units in a manner suitable for operation of a display unit; and a window buffer for transferring display data unit from the source memory to the target memory. The system transfers a quantity of display data unit bytes from the source memory to the target memory by accessing pairs of planar bytes, which pair of planar bytes may have a display data unit byte bridging therebetween. The method comprises selecting a first pair of planar bytes from the source memory; aligning the display data unit byte which lies totally within the selected first pair of planar bytes; selecting a second pair of planar bytes from the source memory; aligning a display data unit byte which lies totally within the second selected pair of planar bytes; consolidating the display data unit byte which bridges between the first and second pairs of selected planar bytes; aligning the consolidated display data unit byte; and transferring aligned display data unit bytes to the window buffer.

    摘要： This invention is directed to relational extenders for a computer-based relational database. Each relational extender includes at least one column, in a first, business, table containing a user defined application database, dedicated to object handles for defining the complex data type of an object; a second, attribute, table containing at least one column defining a unique characteristic associated with the one object and one column dedicated to containing the object handle; and a third, metadata, table containing at least one column defining a common characteristic associated with all objects defined within the business table and one column dedicated to containing the object handle and at least one column dedicated to containing a reference to object data associated with the object. The relational extender further includes a fourth table containing a reference to each object handle column defined in the first table, a fifth table containing the names of the second and third tables for each object defined in the first table, a sixth table containing a reference to each object handle removed from the first table and including one column dedicated to containing a reference to the location of the object data associated with the removed object handle, and a seventh table having at least one column which describes a property of the data type of each object defined in the first table. The relational extender further includes an eighth table as a temporary holding table for the second table, and a ninth table as a temporary holding table for the third table. Both the eighth and ninth tables are used in conjunction with the extender triggers to ensure data integrity.

    摘要： A data processing system includes, among others, three memory areas: a source memory which is addressed in planar, data unit increments and stores display data units on a bit per plane basis; a target memory for storing display data units in a manner suitable for operation of a display unit; and a window buffer for transferring display data units from the source memory to the target memory. The system includes apparatus for inhibiting certain data units from the source memory from overwriting data units already in the target memory. The method comprises first accessing a plurality of data units from the source memory and then logically determining if all bits of each accessed data unit meet a predetermined criteria. Each data unit found to meet the predetermined criteria is inhibited from altering any data unit already in the target memory.
