Abstract: A method (40) and system (10) are provided for knowledge based design. Conceptual model elements (12) are stored. Also, stereotype knowledge bases (14) are stored. Ones of the conceptual model elements (12) are matched with ones of the stereotype knowledge bases (14) to select a closest matching one (16) of the stereotype knowledge bases (14). Design model elements (18) are generated by applying scripts in response to the selected stereotype knowledge base (16).

Abstract: A relational artificial intelligence system is invented and developed. It comprises a relational automatic knowledge acquisition system and a relational reasoning system. The relational automatic knowledge acquisition system is a relational learning system which discovers knowledges from spreadsheet-formed databases and generates relational knowledge bases using inductive learning technique. The relational reasoning system is a relational knowledge-based system which reasons about the generated relational knowledge bases automatically and predicts what will happen under future data readings. The feature of this invention is that every component in this system is relational. Not only the database to be read and the knowledge base to be generated, but also the inductive engine and the inference engine are relational. In the whole reading, operating, and generating processes, data are organized in the spreadsheet-form, and hence the system works with high efficiency and speed.
Abstract: In a multi-layered neural network circuit provided with an input layer having input vectors, an intermediate layer having networks in tree-like structure whose outputs are necessarily determined by the values of the input vectors and whose number corresponds to the number of the input vectors of the input layer, and an output layer having plural output units for integrating all outputs of the intermediate layer, provided are learning-time memories for memorizing the numbers of times at learning in paths between the intermediate layer and the respective output units, threshold processing circuits for threshold-processing the outputs of the leaning-time memories, and connection control circuits to be controlled by the outputs of the threshold processing circuits for controlling connection of paths between the intermediate layer and the output units. The outputs of the intermediate layer connected by the connection control circuits are summed in each output unit.

Abstract: A work station, including a central processing unit (CPU), first, second and third integrated circuit interface chips, connected to an external bus, memory and peripheral unit, respectively, and a local bus, coupled to the CPU and chips. Each chip includes an internal bus interconnecting operating units disposed therein. Each chip is adapted to operate at the same clock frequency as the CPU, but with operational signals generated on its respective internal bus independently of the CPU. The internal bus on the first chip includes a burst mode control line for selected operating units. An operating unit obtaining access to the internal bus and activating its burst mode control line is effective to lock the internal bus for a plurality of operating cycles, during which data is transferred continuously in a burst mode over the internal bus.
Abstract: A quick method of calibrating an industrial robot. A calibrating device (3) which has 6 degrees of freedom and has a displacement detector for each of 6 axes is mounted either to a reference surface (lp) established on the robot (1) itself or to a reference surface having a known positional relation to the robot. The front end of the calibrating device (3) is mechanically coupled to the front end of the wrist of the robot. The position and the posture of the robot are calculated from the data for the position and the posture of the calibrating device derived from the displacement detectors of the calibrating device (3) to calibrate the robot.
