Abstract: Provided is a kernel program and so on capable of enhancing the confidentiality of data memorized in a storage device without using a file system on an OS kernel level. The kernel program is mounted on a computer operable to input and output data between an application program and a storage device, and causes the computer to function as: a socket establisher establishing a socket for connecting with the application program; a relational database operable to input and output data from/to the storage device through a device driver; and an access controller inputting a command from the application program through a message structure of the socket then to output the command to the relational database and inputting an execution result from the relational database then to output the execution result through a message structure of the socket to the application program.

Abstract: To expand the after-sales services offered for a product purchased by a user, a service server that provides services accesses a specified navigation system, which is the product purchased by the user, using a device ID that is uniquely assigned to the navigation system, and then transmits service information to the specified navigation system. In other words, the service server actively accesses a navigation system, which is fundamentally one of countless terminal apparatuses on a communication network, and provides service information to that navigation system. By operating in this way, a great variety of services can be provided whenever appropriate.

Abstract: A system to detect a status of a movable body having a status notification system from information supplied by a plurality of sensors installed on the movable body selectively transmits sensor information to a response apparatus connected to another network in a wireless manner based upon a result of the detection, and when the response apparatus requests additional sensor information, the status notification system transmits the stored sensor information selectively, thereby executing only the communication necessary for movable body rescue and support activities.

Abstract: A service-rendering system wherein control information is generated for controlling operations of a navigation apparatus provided on a movable body by cooperation of a terminal operated by a user and a service-rendering apparatus for rendering services, the control information is transmitted to the navigation apparatus located at a location separate from the terminal and from the service-rendering apparatus, and information on navigation is generated prior to use of the movable body by the user.

Abstract: A service-rendering system is disclosed. In the system, control information is generated for controlling operations of a navigation apparatus provided on a movable body by cooperation of a terminal operated by the user and a service-rendering apparatus for rendering services, the control information is transmitted to the navigation apparatus located at a place separated from the terminal and from the service-rendering apparatus, and information on navigation is generated in advance prior to use of the movable body by the user.

Abstract: The invention is intended to detect a status of a movable body having a status notification system from information supplied by a plurality of sensors installed on this movable body, selectively transmit, on the basis of the result of the detection, the sensor information to a response apparatus connected to another network in a wireless manner, and, when the response apparatus requests additional sensor information, the status notification system transmits the stored sensor information selectively, thereby executing only the communication necessary for movable body rescue and support activities.
