摘要:
A communication system includes an information terminal apparatus having at least a data collecting portion for collecting appliance information of an appliance, a data processing server apparatus and a communication device which can be communicated with the information terminal apparatus, and first and second communication networks for connection between the information terminal apparatus and the data processing server apparatus. The first communication network is a communication configuration with a high speed digital transmission technique, and the second communication network is another communication configuration providing service for telephone subscribers. The information terminal apparatus communicates the appliance information with the data processing server apparatus through the first communication network, and uses the second communication network for communicating a particular appliance information with the communication device.

The invention provides a communication apparatus used inside a house, a communication system connected thereto, a communication process, and computer program used therefor. The communication apparatus of the present invention connected via a network to one or more terminal appliances in the house, communicates with an outside via two or more different communication configurations including a first communication configuration with a high speed digital transmission technique and a second communication configuration providing service for telephone subscribers. The communication apparatus is characterized in recognizing a situation thereby to disconnect the first communication configuration and to use only the second communication configuration for communication with the outside.

A monitoring system for preventing crime in a home, includes a plurality of terminals for monitoring whether predetermined monitoring points are in a stationary or nonstationary state. Further, the monitoring system includes a central processing device for controlling the setting/canceling of alarm operations of the terminals. The central processing device has a communication unit that receives stationary/nonstationary information from the terminals and transmits predetermined information including commands to the terminals. Each terminal has a communication unit that transmits stationary/nonstationary information to the central processing device and receives the predetermined information from the central processing device. Thus bidirectional communication can be achieved between the central processing device and the terminals. The terminals may include a terminal with an emergency call unit which, in an emergency, calls or notifies another, and a terminal having a notification unit which indicates that a nonstationary state has been accepted by a predetermined point of contact.

A monitoring system which is suitable for, for example, preventing crime for a residence, includes a plurality of terminals (31, 32, . . . ) for monitoring whether predetermined monitoring points are in a stationary state or a nonstationary state, and a central processing device (10) for controlling a setting/canceling operation of alarm operations of the terminals (31, 32, . . . ). The central processing device (10) has a communication unit that receives information related to the stationary/nonstationary states from the terminals and transmits predetermined information including commands to the terminals. Each terminal has a communication unit that transmits information related to stationary/nonstationary states to the central processing device and receives the predetermined information from the central processing device. Thus bidirectional communication can be achieved between the central processing device and the terminals. The plurality of terminals (31, 32, . . . ) may include a terminal with an emergency call unit which operates in an emergency to call or notify, and a terminal having a notification unit which indicates that notification of occurrence of nonstationay state has been accepted by a predetermined point of contact.
摘要:
A system is provided for managing a storage medium on which management information, data and associated history information are recorded. The system packs and records history information pieces, which have been recorded on a plurality of sectors, on a single physical sector, or the management information is backed up at a predetermined time point, so as to reduce overhead required for reproduction of the history information during reconstruction of the management information and to speed up the reconstruction processing of the management information. Particularly, achievable high-speed processing for reconstruction of the management information during initialization leads to efficient management of an external storage unit of a document filing system or a computer using the management system.

An indoor dust collecting system includes an air conditioner having an indoor unit that generates an air current, a dust collector, and a controller for controlling the air current from the indoor unit. A moving body detector is provided to detect a moving body such as, for example, a person, a pet, a cleaning robot, and the like. The air current from the indoor unit is controlled by the controller based on the position of the indoor unit, the position of a spot of occurrence of dust detected by the moving body detector, and the position of the dust collector such that the air current from the indoor unit reaches the dust collector via the spot of occurrence of dust in order for the dust collector to effectively suck the dust.
摘要:
A system for managing a storage medium such as a write-once type optical disk in which addresses of logical blocks are assigned in accordance with the kinds of information to be recorded, and the number of physical sectors necessary for recording or reproduction on the basis of the logical block addresses. The number of physical sectors to be used can be reduced, improving the efficiency of the storage medium. Two or more kinds of information can be mixedly recorded in one physical block. The OS can manage the physical blocks as logical blocks in which the two or more kinds of information are separately recorded.

摘要:
Areas in an optical disk are classified into three categories including file areas, used areas, and erased areas for management purposes. An erasing process to convert a used area into an erased area is executed asynchronously with a writing process, thereby preventing any decrease in data transfer speed due to the effect of the erasing process upon the writing process. On the other hand, the file areas, used areas and erased areas are managed as continuous areas which are designated by the head position and the size or end position of the area. A file is preferentially assigned from an erased area or a used area of a large size. With such a construction, area management, such as an integration of the erased area or the like, can be easily performed. Also, the file can be assigned to the continuous areas, and the access speed can be improved.
