Abstract: A home appliance monitoring system includes: a plurality of home systems respectively including a central managing device configured to collect monitoring information from a home appliance; and a center server connected to the central managing device of each home system. The center server calculates the current load amount, and sends an activating instruction signal or a deactivating instruction signal to each central managing device on the basis of the current load amount. The central managing device sets its communication status to an activated status in response to receiving the activating instruction signal, and sets its communication status to a deactivated status in response to receiving the deactivating instruction signal. The home system stores the monitoring information while the communication status is the deactivated status. The home system sends the stored monitoring information to the center server when the communication status is switched from the deactivated status to the activated status.

Abstract: The home appliance managing system includes a plurality of central managing devices and a center server. The center server is connected to the plurality of the central managing devices, and stores plural data used at home appliances. When the central managing device stores predetermined data requested by the home appliance, the central managing device sends the predetermined data to the home appliance. When the central managing device does not store the predetermined data, the central managing device requests the predetermined data from the center server. The center server sends the predetermined data to the central managing device in response to the request from the central managing device. The central managing device sends the predetermined data received from the center server to the home appliance and stores the same data.

Abstract: Provided is an environment which enables a user to implement 3D space design on a computer accessible to a server computer via a network. The server computer includes a layout design program which is operable on a screen activated by a browser of the client computer to enable the user to implement space design of a layout in the terms of a 2D image, an object database which stores object data used for layout design for retrieval and extraction, and a 3D display program which is operable on the browser screen of the client computer to display the designed space in the terms of a 3D image. The client computer is equipped with the browser capable of executing programs of the layout design program and the 3D display program. Upon receiving the layout design program and the 3D display program from the server computer via the network, the programs of the layout design program and the 3D display program are executable on the browser screen.
