    摘要： A system of physical optics is provided which is employed in the design of indoor wireless communication systems, where transmitters are placed and oriented within a model of a building complex. The system provides for forward tracing of rays, which makes practical signal coverage displays that respond interactively to communication system design changes. The physical optics system consists of a method of generating semi-rectangular cone elements covering space, and a method of enumerating receiver test points within each cone for accumulation and display of electromagnetic signal coverage.

    摘要： The invention describes a clause counter map inference engine which is an interpreter method based upon the Boolean form, in which Boolean inference is directly assisted by a programmable data structure. The system provides a translation of a series of Boolean logic functions into a compact map representation, which may then be used for Boolean inference by means of an interpreter algorithm or inference engine adapted to update function values based upon any changed input value. The invention provides a rule-based model for logical control systems having an imbeddable, event-chaining inference engine which is independent of the rule-based model. The time to complete a scan cycle of the system depends directly upon the number of inferences in an up-date interval between input and output variable changes, and the lengths of inference chains of events in the logic. The clause counter map inference engine generally provides a method of implementing logical functions where inferencing is at an optimum, thereby reducing inference processing time and providing a system which may take the place of other on-line control methods for implementation of a PLC, and also may be applied to expert and knowledge-based decision systems which utilize logic programming and rule search methods.
