Abstract: An intraoral camera system includes an imaging unit and an image determination unit. The imaging unit generates an image data item showing a target tooth for image capturing inside a mouth. The image determination unit defines two-dimensional plane coordinates for the image data item generated by the imaging unit and extracts the position coordinates of the outline of the target tooth from the entire imaging area of the imaging unit. When a part of the outline of the target tooth is outside an effective area set inside the entire imaging area of the imaging unit, the image determination unit determines that the target tooth extends beyond the effective area.

Abstract: An intraoral camera system includes an imaging unit and an image processor. If a first angle formed by an imaging plane perpendicular to the optical axis of the imaging unit and a first direction that is the vertically upward direction along a vertical axis is less than a predetermined second angle, the image processor rotates image data to cause the vertically upward direction along the vertical axis to coincide with an upward direction of an image by rotating the image data by a third angle formed by the first direction and a second direction from a handle toward a head.

Abstract: A control processing method of an electric device for implementing an operation content indicated by an operation command received from a control terminal, the method including a step of discriminating whether the received operation command is a predetermined operation command, and a step of notifying the control terminal that the operation content indicated by the operation command has not been implemented without implementing the operation content indicated by the operation command, in a case where the received operation command is the predetermined operation command. Therefore, in a case where a command specification of an industry standard is designed, although the electric device receives an unsupported command, it is possible to obtain that the electric device is smoothly controlled.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
