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. Each device locally and continuously determines a device to be linked with it or whether to perform a link operation requested by another device, using the shared conditional information, information on the surrounding environment, and the policy 124. The results of a link operation are made public and shared by each device through the link control processing 113, and used for narrowing the range of link target devices.
摘要:
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.

摘要:
In an information processing system having plural processing units connected through a communication medium, each processing unit operates to receive information to be transmitted from a processing portion operating in the processing unit to the communication medium and a content code predetermined according to the content of the information to be transmitted. Based on the received content code, the processing unit operates to determine an address of the destination processing unit, a sending mode used for transmitting the information, and whether or not the more reliable communication method arranged to establish a connection between the processing units is used for transmitting the information. Then, by using the sending mode and the communication method obtained as the determined result, the information is transmitted to the processing unit having an address obtained as the result determined through the communication medium.

The present invention provides a highly sensitive and practical method for the determination of and the separation of 5-hydroxycreatinine from a sample of bodily fluid. The method of the present invention is useful as a method for the testing of renal dysfunction, such as uremia, chronic nephritis and closure of the urinary tract, etc. A separation solvent of pH 4.1 to 4.6 is used in a high performance liquid chromatography step that is carried out using a strongly acidic cation-exchange resin, such as a styrene-divinylbenzene resin. The determination sensitivity is a concentration of only about 0.02 &mgr;M, whereby 5-hydroxycreatinine in blood of healthy persons can be determined for the first time. Moreover, only one separation solvent, such as a citrate, need be used and the cycle time for analysis is only about 14 minutes per measurement. Thus, a practitioner using one set of HPLC equipment is able to carry out about 100 determinations per day.

According to the present invention, a file recovery system is provided in which the commands for recovering files such as a historical file are unnecessitated and the recovery system configuration is independent of the host processing system. That is, since the equipment for achieving a file recovery does not have information about the location of the recovery data, information about the content of a file to be recovered is transmitted to a transmission line. The other equipments asynchronously receive the information and judges whether or not a file containing the same content exists in the own system. If its file exists, the content of the file is transmitted to the transmission line. The equipment achieving the file recovery asynchronously receives from the transmission line the file data of files such as a historical file and establishes data consistency by use of the buffered current data and the event number, thereby recovering files such as a historical file.
