The equipment management device includes an information collection unit, a specific state detection unit, a cause estimation unit, and a countermeasure process execution unit. The information collection unit acquires a video of a conference room or a sound of the conference room. The specific state detection unit detects that equipment provided in the conference room is in a specific state on the basis of a result of analyzing the video or the sound. The cause estimation unit acquires equipment information about the equipment when the equipment has been detected to be in the specific state and estimates a cause of the specific state on the basis of the equipment information. The countermeasure process execution unit selects and executes a countermeasure process to be executed on the basis of the estimated cause.

A terminal device presentation system () includes: a relay device () which relays communication between a display device () and a terminal device (T), transmits an image signal from the terminal device to the display device and causes the display device to display the image signal; and a terminal connection processor () which performs processing of connection to the relay device in the terminal device, wherein the relay device includes a connection processor () which transmits connection information of an accessible network to the terminal device, and the terminal device includes a switching control unit () which connects the terminal device to a second network that is accessible for at least the relay device and different from a first network and is set in the terminal device such that a user of the terminal device uses the second network in preference to the first network, when the terminal device is connectable to the second network.

A projector selection system selects one of projectors from a computer which is connected to the projectors through a network. An identifier is displayed on each of the projectors by identifier assigning means and identifier display means. A preview image, which is a scale-down version of an image displayed on the screen by the projector, is acquired by preview image generating means and preview image transmitting means. The preview image is displayed on a dialog display area on the screen of the computer.

Projector selection system, projector selection method, and program for implementing the system and method

A storage system, a storage management method, and a control program product are provided. The storage system is improved in comfortability, convenience, and economy by reducing the amount of copies in a storage device in a network storage system, by heightening storage efficiency and increasing an access speed. In a network storage system in which a plurality of client terminals are directly connected to a storage device via a network, the storage device includes an MV logical disk that stores read-only shared data and a BV logical disk from/onto which data specific to each client terminal is read/written. A control unit that controls read/write operations includes, with an access management table, an LDK management table which has a reference logical disk number column used to issue a command to refer to the MV logical disk when data other than the write data is read.

Network storage system, management method therefor, and control program product therefor

A disk array apparatus and an interrupt execution method of the same enables command processing received from an upper level apparatus to be executed in high-speed by reducing rate of the interrupt and substantial processing speed not to decrease even when a write command from the upper level apparatus is continuously executed. A configuration is capable of executing selectively either an immediate interrupt or a delay interrupt. Selection is made to execute the immediate interrupt in the case of a write command while in the case of a read-out command, the delay interrupt is selected. Moreover, Judgment whether or not competition of page occurs when the write command is detected, namely whether or not a region of a cache memory that becomes execution object of the command is used is performed. Only when competition of the page occurs, handling is switched from general delay interrupt to an immediate interrupt. It is possible to reduce waiting time caused by competition of the page while immediately releasing the region of the cache memory that becomes execution object of the command.
