  • Patent number: 7228561
    Abstract: In distributed system for operating devices in association with one another, a device responsible for determining whether or not an access is permitted, and criteria for determination are hidden from accessing device or user, and flexible access control is provided among devices without need for previously defining accessible devices or user's identifiers. Communication process opens data communications which are interactions between devices to permit indefinite number of other devices to monitor data. A behavior monitoring process acquires interaction within particular device or between other devices in system for storage in behavior log table. Access control process matches the behavior log table with access control policy to determine whether or not device should be associated with target device from which process request is received, or with a target device to which a process program of the particular device attempts to access.

  • Patent number: 6983306
    Abstract: The present invention relates to a distributed system in which processors incorporated in machines and objects are mutually linked in operation, and an object of the present invention is to provide a distributed system in which each device can establish a link with a suitable device according to changes in the environment and conditions, independently from the system configuration controlled by a server. In order to achieve the above object, each device provided by the present invention obtains information on surrounding devices through a sensor 131 or communication processing 112, recognizes the environment around it through environment recognition processing 111, and stores the environmental information in an environment management table 123. By employing link control processing 113, each device shares conditional information stored in a profile 122 and a policy 124 of each device through the communication processing 112.

  • Patent number: 6697836
    Abstract: A client (referred to as A) transmits a request to a service mediate server (referred to as B) through a communication medium. B receives information. A server (referred to as C) receives a request for obtaining information from B and transmits information requested by B. B receives a request from A. A service mediate managing unit determines a type of information to be provided to A, based on the attribute information of the content of the request, the customized information of A and C pre-stored in the service mediate managing unit, and various status at the receipt of the request. The service mediate agent selects any one of plural Cs and transmit the request for obtaining information to the selected C. The information received by C is processed by the service mediate agent and the processed information is transmitted to A.

  • Patent number: 5638492
    Abstract: An information processing apparatus is capable of achieving high-level functions such as high-speed processing and learning without requiring a complex algorithm based on, for example, knowledge processing. A plurality of sets of known input data and correct output data corresponding thereto are beforehand stored. The stored input data is called response pattern data. Data actually inputted in the system operation is supplied to the plural sets of data. For each set of data, the input data is compared with the response pattern data to evaluate a distance (degree of similarity) therebetween. Results of evaluations for the respective sets of data are combined with the associated output data, for example, according to weighted average values on the basis of the evaluated distance, thereby generating final outputs.

  • Patent number: 5463718
    Abstract: In a learning method, training data and verification data each including a set of input and output values are taken as teacher data, and a change of an error between an output value calculated by use of the input data of the verification data and the output value of the verification data and a change of an error between an output value calculated by use of the input value of the training data and the output value of the training data are simultaneously displayed, thereby preventing an overlearning and reducing the number of times of learning. Also in the learning method, fuzzy knowledge data is inputted and displayed, a range of the object of learning is interactively designated from among the displayed fuzzy knowledge, and a learning is made on the basis of a predetermined learning algorithm to change the fuzzy knowledge in the designated range, thereby performing the learning of a fuzzy knowledge with a user's intention reflected.

  • Patent number: 5251285
    Abstract: A prediction control of a process containing a non-linear behavior is effected by predicting a transition of process quantities (control quantities) of an object to be controlled a predetermined time period after the current time to provide predicted values and by determining manipulation quantities of at least a control effector in accordance with a difference between the predicted values and predetermined target values of the controlled object. A quantitative operation is carried out arithmetically identifying a process as a linear behavior, and a fuzzy inference or qualitative operation, including a fuzzy rule based on empirical knowledge, is carried out for simulating a process, wherein for input process information and current manipulation quantities to be maintained, both operations parallelly determine predicted values of control quantities. A process behavior determination is arithmetically carried out to determine whether the process linearly behaves (i.e.

  • Patent number: 5208898
    Abstract: A knowledge processing system in which a grade representing a degree at which an event is satisfied or unsatisfied is obtained depending on a condition part represented in a form of a logical arithmetic expression including an expression of a fuzzy logic and on a grade of satisfaction of the condition part generates rules on assumption of unmeasurable events associated with states of the external field of the system so as to add the rules to the rules related to the unmeasurable events. Forecast of a value of a measurable event is more correctly achieved depending on grades of satisfaction of the unmeasurable events and grades of satisfaction of measurable events. A warning may also be issued according to the forecasted value.
