An intraoral camera system includes an imaging unit that generates image data by capturing an image of a tooth inside the mouth of a user, an area detector that detects the orientation of the imaging unit according to output by a multi-axis acceleration sensor and detects, according to the orientation detected, an area whose image is being captured by the imaging unit from among areas inside the mouth, the areas being determined by dividing a dentition into sections, and an identifier that narrows candidates which are combinations of tooth types and tooth positions down to fewer candidates to be used, according to the image data and the area detected, and identifies the type and the position of the tooth according to the narrowed candidates and the image data.

Intraoral camera system, tooth identification method, control method, and recording medium

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.

The invention provides a communication apparatus used inside a house, a communication system connected thereto, a communication process, and computer program used therefore. The communication apparatus of the present invention connected via a network to one or more terminal appliances in the house, communicates with the 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.

Communication apparatus of a home security system

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.

Monitoring system

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.

Method of managing storage medium

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.

System for managing a storage medium reducing physical space needed

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.

Recording area management system for writable type optional disk

An information management system for writable optical discs, includes a disc (7) on which data (7a) and management information (7b) are recorded; an operating system (1) in which data in a read only optical disc can be managed by means of files, the operating system (1) having a read instruction (2) and a write instruction (3); read control portion (5) for changing the read instruction directed to the read only optical disc into a read address instruction directed to the disc (7), the read control portion (5) having modifying and loading portion (5b) for changing the management information (7b) into mutual information having a format of the read only optical disc; internal storage (5c) for storing the mutual information; and access changing portion (5d) responsive to the read instruction (2) for switching an access target such that the access target is the disc (7) when the read instruction (2) is directed to the data recorded on the disc ( 7), and that the access target is the internal storage (5c) when the read instruction (2) is directed to the management information (7b) recorded on the disc (7); and write control portion (6) for renewing the address modifying information in the read control portion (5) in response to the write instruction (3) when new data is written in the disc (7).
