Abstract: A layered document services architecture (10) facilitating operation and interconnection of electronic printing systems with both resident and non-resident work inputs. The architecture has a resource layer (16) providing a series of discrete modules and facilities for processing work; an applications layer (14) for enabling input of work from both resident and non-resident sources including a document services section (26), and a service manager means (40) for coordinating and controlling access to the modules and facilities of the resource layer (16), and a control layer (18) providing an operating system for coupling the resource layer (16) and the application layer (14) together in an operating environment, the control layer (18) including a resource controller (210) for prioritizing and distributing use of the source layer modules and facilities in accordance with program inputs and system operating conditions.

Abstract: High resolution character generator for producing rows of characters to be scanned on a display medium. Input data defining characters to be printed in ordered rows of text is sorted to provide specifications for the characters which begin on each successive scan line. These specifications are stored initially in an input buffer, and specifications for characters which have been partially printed in a previous scan line are stored in an active character buffer. For each scan line, the character specifications are read first from the active character buffer and then from the input buffer until an end of line specifier is reached. For each character specification received, a font memory containing data defining the characters is cycled. The data from the font memory is decoded and presented to the display medium on a line by line basis.

Abstract: The invention relates to a position indicator which rides over a surface for controlling a cursor over a visual display. The indicator generates signals indicative of its positions to cause the cursor to be displayed on the display at a corresponding position. The indicator includes a control mechanism that comprises a transport sphere in combination with position wheels indicative of Cartesian coordinates. The sphere is in contact with the surface over which the indicator rides and the position wheels contact the sphere at a position on the sphere approximately 90 DEG from the contact loci of the sphere and the surface.

Abstract: The invention provides a method for operating a memory which is capable of storing a two-dimensional page bitmap including one or more two-dimensional rectangular image bitmaps, wherein each image bitmap is represented by a plurality of words forming columns and rows in direction of the first and second dimension respectively. The number of said words in each column is even. In a first step, the sequence of the words of one of said image bitmaps is changed, wherein the words of one set of columns is in sequence and the words of the other set of columns is in a swapped sequence. Then, the image bitmap is loaded into said memory region column by column by sequentially loading the words in the changed sequence, wherein the words of said one set is loaded into sequential locations and the words of said other set is loaded into the location that would result if the least significant bit of each successive addresses was reversed. Finally, the entire page is sequentially read out from said memory, by row or column.

Abstract: A system for merging image and text information, and for producing electronically collated document sets locally or remotely through the use of a communication link. The main components of the system are an image input terminal for scanning in and digitizing images, an electronic input module for compressing the data, a mass storage device, a variety of peripherals for the input of character coded data, a bit map display, an electronic output module for decompressing and merging data, an image output terminal for producing copy sets, a communication link for the exchange of data with a remote station, and a processor with memory for controlling the I/O bus connecting the elements.
