An electronic control system for a television receiver (12) incorporates a light pen (10) which can be applied to selected portions (16) of the screen (14). These portions (16) are modulated (FIG. 2) at the field scan rate by data inputs such that in successive television fields they are black or wh ...
The menu hierarchy of one or more computer programs on one or more computer systems is visually displayed in a graphical tree structure to facilitate the navigation by a user from one menu in a hierarchical structure of menus to another. Navigation from one menu to another is accomplished by selecti ...
A wall panel has a glass outer face which in turn is provided with a decorative design, for example by painting, mirroring, partial mirroring, coating, printing or else placing an inlay or the like behind it. In addition, this wall panel is designed to cooperate with a flat screen in such a way that ...
A color graphics system for displaying a plurality of polygons, based upon polygon commands supplied by a host computer. The system accepts the commands from the host and circulates them in a circular queue past a polygon processor or "painter's station" which examines each to see if it is on the li ...
A "flying field" computer aided interactive microscopical mapping system has been developed that enables an operator to map over a region of the specimen covering many microscopical fields of view without the discontinuities associated with moving the stage and then generating mapping marks as separ ...
An enhanced single frame buffer video display system is described for combining both video and graphical images. A single frame buffer is implemented which stores a single data format for pixel types which may be interpreted by a conventional video generator for output to conventional color graphics ...
A display control system has a digital interface therein. When software using a color display is executed and displayed in a monochrome monitor, this system is responsive to color code information to arbitrarily select either a hatching pattern conversion or a grey scale display according to applica ...
A multi-media presentation system is disclosed for coordinating access to multi-media presentation data and related information. The multi-media presentation data typically includes text, image data and layout data. The related information is stored in an item header file, as well as in a number of ...
To generate two-dimensional images of three-dimensional solid objects at high speed, an object is defined within a three-dimensional universe hierarchically subdivided into a plurality of discrete volumes of uniform size and similar orientation. The three-dimensional universe is represented by an oc ...
A multiprocessor system for forming a color picture from object elements defined in a hierarchic data structure. The object elements are Bezier polygons each of the sides of which forms a Bezier curve. There is provided an array of parallel connected point processors which perform three functions. F ...
