A control device including a failure diagnosis unit configured to identify a phenomenon that is a cause of the detected error, wherein the failure diagnosis unit is configured to: calculate a diagnosable time available to be spent on the identification of the phenomenon that is the cause of the error; and identify, for each detected error, a phenomenon that is the cause of the error based on a posterior probability, which is calculated for each phenomenon that is likely to be the cause of the error as a probability of occurrence of the phenomenon, on a diagnosis time, which is obtained for each phenomenon as a period of time required to identify the phenomenon as the cause of the error, and on the diagnosable time.

Control device, and processing method in event of failure in control device

A display system is provided which determines an effective image area by automatically detecting a boundary between the effective image area and a non-image area created owing to the difference between the pixel numbers of the camera image sensor and television signal, to thereby display the images on a monitor by adjusting a display size and position suitable for the effective image area, whereby an inappropriate display size and position are avoided from being set while a lighting device for illuminating a camera's field of vision is off. The display system receives a signal notifying about activation of the lighting device from the lighting controller that provides on/off control of the device; the system then determines the effective image area if the device is on, and does not if it is off.

Display system

Responsive to a proxy authentication request from a network terminal, a display for prompting a user to start an authentication operation is performed; authentication data for performing personal authentication are read by a user operation; an authentication request is sent together with the read authentication data to an authentication server; an authentication result is received from the authentication server; the network terminal is notified of the result. When a service requiring personal authentication is used, via a network, a request for proxy authentication can be made from a network terminal lacking an interface for personal authentication to a proxy authentication terminal having an interface for personal authentication, whereby the interface of the proxy authentication terminal can be used to perform the personal authentication.

Authentication terminal and network terminal

A video/audio playback apparatus that can continue playback even if the external storage means are disconnected during playback, includes a virtual file system sectionfor merging the video/audio information and playback control information of the optical discwith the video/audio information and playback control information of the local storageto configure a virtual file system; a pseudo file system generatorfor generating a pseudo file system; a RAMfor storing the generated pseudo file system; a disconnection detectorfor detecting disconnection of the local storagefrom the connecting section; and a playback managerfor causing the virtual file system sectionto merge the video/audio information and the playback control information of the optical discwith the information of the pseudo file systemimmediately after the disconnection is detected, thereby newly configuring the virtual file system.

Video/audio playback apparatus

A file transfer method and a file transfer system are provided for making it possible to minimize aggregate waiting time of the whole users for data transfer using a multicast protocol. In the file transfer method of transferring a plurality of program files from a recorder storing a plurality of program files via a network to a plurality of mobile terminals using a multicast protocol, the recorder determines order of transfers of the plurality of program files for the purpose of transferring the plurality of program files in order of digital data files, which is the ascending order of file size of the plurality of program files (step S), the recorder transfers the plurality of program files on the basis of the order of transfers (steps S-S), and the plurality of mobile terminals selectively receives the plurality of program files (steps S-S), thereby reducing aggregate waiting time that is a sum total of transfer time of the whole users.

File transfer method and file transfer system

An information processing apparatus in which its function can be improved by installing an additional module to an existing module in a module configuration system. A video information processing apparatus, which is an existing module, has the function of reading, from a network moduleas an additional module, software held in the network module. The software held in the network moduleincludes control software for the network module and software for making the control software available to the existing video information processing apparatus. The software held in the network moduleis added to the video information processing apparatus, and the network moduleis operated by the video information processing apparatus

Apparatus and method for controlling periperal device in response to connection thereto

Provided is a gateway device for interconnecting an IEEE1394 network and an IP network, which automatically detects and operates an AV device connected to the IEEE1394 network from a player device connected to the IP network, thereby enabling the player device to watch and hear contents stored in the AV device. The gateway device interconnects a network, to which an AV/C installed IEEE1394 device is connected, and a network, to which a player device compliant with a UPnP is connected, and includes: a conversion unit for converting Plug-and-Play processing of the IEEE1394 device to each step of Plug-and-Play of the UPnP; a conversion unit for converting an action of a UPnP AV to an AV/C command of the IEEE1394 device; and a stream transfer unit for transferring stream data transmitted from the IEEE1394 device to the IP network.

Gateway device

There is provided a serial transmitting section for serially transmitting a command frame which is sent from a host controller to a positioning type servo amplifier and a command follow-up type servo amplifier . In the command frame , an information section, into which information to be transmitted is inputted, has discrimination data for showing a selection between the positioning type servo amplifier and the command follow-up type servo amplifier . In the positioning type servo amplifier and the command follow-up type servo amplifier , there is provided information reading section for reading the content of an information section after the discrimination data of the command frame by the discrimination data of the command frame

Servo control system

A servo control method is realized by connecting a high-speed serial communication interface with a microcomputer, a dual port memory and an IC for high-speed serial communication mounted thereon to an extended bus of a personal computer and by connecting between the high-speed serial communication interface and a plurality of servo controllers with a serial line in a multi-drop system.
