Abstract: A method and system for management of a presence information by a message server. A presence information of at least one member listed on each communication group member list belonging to each user is notified. A presence information is renewed, which belongs to a terminal of a user as sender who sends a message to the message server. The presence information is automatically renewed in response to at least one of a first type event that the message server has received at least one of the message and any other communication from the user as sender, and a second type event that an effective time period for the presence information has expired.

Abstract: A program executing apparatus includes a first storage section which stores data permitted to be leaked out, a second storage section which stores secret data of a user, a communication section which can communicate with an external unit, and a program storage section which stores at least one application program. A program executing section interprets and executes the application program, checks a possibility that the secret data is leaked out to the external unit while interpreting the application program, and stops the execution of the application program when it is determined that there is the possibility that the secret data is leaked out.

Abstract: A system controls notification of a user location to a server in accordance with a notification control condition including a not-notifying condition and a process termination condition The location of the user is detected by a location detector. The server is not notified of the location of the user terminal when the not-notifying condition is satisfied unless the process termination condition is satisfied. When the process termination condition is satisfied, the location notification is terminated.

Abstract: In a content delivery system, a gatekeeping apparatus is connected to a network. Prior to the transmission of a request message to a content server, a user terminal transmits an enquiry message to the gatekeeping apparatus. In response, the gatekeeping apparatus makes a decision as to whether or not a content can be retrieved from the content server and performs control on the transmission of the request message according to the decision. If the decision indicates that a content can be retrieved, the user terminal transmits the request message to the content server. In a preferred embodiment, the gatekeeping apparatus makes comparison between user's preference data and server's policy data and determines whether the requested content can be retrieved from the server. A cache memory may be provided in the user terminal or gatekeeping apparatus to store past decisions regarding requested contents.

Abstract: Messages with a valid range are selected by a message filter unit among the messages received through a network by a message reception unit, and the selected messages with a valid range are temporarily stored in a message storage unit. A message delivery assessment unit compares periodically the valid range of the stored message with a valid range with a current position obtained by a positioning unit, and a message delivery unit delivers the message with a valid range for which the current position is in the valid range, to a user. As a result, the message reception device can deliver the message valid in a specific location to the user with an appropriate timing.

A notification server, notification method, and recording medium are also disclosed.

Abstract: In a local area network, at least one host terminal has an application program and operates as a source host and other host terminals operate as destination hosts. Each host terminal executes a file management program. The source host, when executing its file management program, updates its management table with an application name identifying the application program and a file name, and transmits a request message to the destination hosts. Each destination host, when executing its file management program, responds to the request message by acquiring the application program from the source host if the application program is nonexistent in the destination host and updates its management table with the application name and the file name. Each host terminal starts the application program by opening a file identified by the file name and collaborates on a joint project with other host terminals.

Abstract: The cooperative work support system of the present invention has at least a first terminal and a second terminal in a communication network, wherein each terminal comprises: a file system for storing a shared file; a file transmitter for transmitting the shared file between the first terminal and the second terminal; and a sharable file list manager for registering shared file information into a sharable file list. The sharable file list manager in the second terminal determines whether the shared file exists within the second terminal based on the shared file information, and sends a transmission request to request the first terminal to transmit the shared file to the second terminal when the shared file does not exist within the second terminal. The file transmitter in the first terminal sends the shared file from the first terminal to the second terminal through the communication network in response to the transmission request.

Abstract: A data reception section of a document publication system receives document data that is inputted as an object of publication, and supplies the received document data to a data registration control section. The data registration control section which received the document data registers the document data in a data storage section. A data publication section publishes (opens to the public) the document data that has been registered in the data storage section by use of a public medium such as the Internet, television, radio, newspaper, magazines, etc., while the data registration control section records publication time of the document data by the data publication section in a management table. When there is a request for the verification of publication time of document data, the data registration control section searches the management table and the data storage section and thereby obtains the document data and publication time of the document data.

Abstract: When a key is inserted into a key hole of a lock, magnetism creating means creates a magnetic flux corresponding to a predetermined magnetic code set in the key. Magnetism detecting means detects the magnetic flux and outputs a signal representing the detected magnetic flux. Decision means compares the signal value with a predetermined value, and outputs an agreement signal when the two values are the same. Driving means enables at least unlocking by key operation in response to the agreement signal. The magnetism detecting means outputs, as the above signal, a voltage corresponding to the magnitude of the detected magnetic flux or pulses having a frequency corresponding to same. At least one of material, dimensions, and thickness of the magnetic element determines the predetermined magnetic code. Further, an unlocking mechanism has a magnetic actuator which unlocks the lock by coupling the lock with unlocking means via a cam in response to the agreement signal.

Abstract: In a cage position detector for a hydraulic elevator, there is provided a detector for measuring the time duration of the power failure, when the power fails. An amount of sinkage of a cage during the power failure is obtained by the time duration of the power failure and an average sinkage amount per unit time provide in advance. A cage position, which has been detected just before the power failure, is corrected by the above obtained amount of sinkage of the cage. A cage position, from which the elevator is to reopen a normal operation for service after the recovery of power, is specified by the corrected cage position.According to the present invention, even though the cage sinks during the long power failure, it is prevented to lose the true present position of the cage, from which the elevator is to reopen the normal operation after the recovery of power.
