Abstract: A data transfer device calculates a compression performance value which represents a quantity of data that can be compressed per unit time and a transfer performance value which represents a quantity of data that can be transferred per unit time, and calculates, based on these values, a compression ratio which represents a ratio of data to be compressed and then transferred to total data to be transferred. The data transfer device extracts, from a storage unit which stores data, the data to be transferred, and then compresses part of the extracted data based on the compression ratio, and transfers the compressed data and remaining data to another device. The compression and transfer processes are performed in parallel.

Abstract: Comfortability can be visually displayed for a user in real time while power consumption is controlled. A display device communicates to/from a power control device for controlling power of a power consumption system including a plurality of apparatus. An input unit specifies a desired set value for each of the plurality of apparatus or a power consumption system including the plurality of apparatus. A display unit displays a display content corresponding to a degree of divergence in real time when an amount of upper limit power for the entire power consumption system including the plurality of apparatus is set, the degree of divergence being calculated based on a comparison between an actual set value for the plurality of apparatus having an amount of power being subjected to demand control based on an evaluation function set for the plurality of apparatus and the desired set value specified through the input unit.

Abstract: A vehicle information acquisition system includes a vehicle and an information management center. The vehicle includes an information acquisition portion that acquires a piece of vehicle information, which is processed by an information processing unit, based on a set collection condition, and transmits the acquired piece of the vehicle information to the information management center. The information management center determines a new collection condition for the piece of the vehicle information, which is processed by the information processing unit, based on a result of an analysis of the transmitted piece of the vehicle information, and transmits the determined collection condition to the vehicle as a collection condition for a piece of vehicle information to be subsequently acquired by the information acquisition portion to re-set the transmitted collection condition in the information acquisition portion.

Abstract: Realized is load distribution among a plurality of nodes that store data updated over a wide range with high frequency. A data placement system includes a plurality of nodes that store data transmitted by client nodes and a distributed access node arranged between the plurality of nodes and the client nodes. The distributed access node comprises a node area information holding unit that holds node area information associating each of the nodes with at least one piece of area information, an area specifying unit that specifies an area where the client node is located, and a node specifying unit that selects a node associated with the specified area as the storage location of data transmitted from the client node.

Abstract: When connecting a mobile information terminal to a communication network via a public access point, a user of the mobile information terminal is undesirably required to input detailed information for connection to the communication network via a poor input interface. In order to solve this problem, the information acquisition function receives network connection setting information from a setting information distribution server which distributes network connection setting information which is information indicative of settings of connections with communication networks. In accordance with the network connection setting information received by the information acquisition function, an NW connection function establishes a connection with a communication network via an access point.

Abstract: When a program is introduced into a computer terminal from an external source via a wired or wireless network or by using an external memory card, unauthorized access by the introduced program to various functions within the terminal is prevented by verifying the source from which the program was distributed and performing execution control appropriately according to the identity of the program. In order to reference the security policy data which specifies functions available to each program given from an external source and restrict functions used by the program, the information concerning the security domain or the certificate or signature attached to the program is extracted, and the extracted information is associated with one of a plurality of function access types held as security policy data.

Abstract: An information processing device, a device access control method, and a device access control program are provided. When a device built in or mounted on the information processing device is controlled, the OS manages access to the device driver, so as to restrict the use of the device. When issuing a control instruction to a device driver (22) that controls a device (4), an application (1) accesses a system call unit (21) in the OS (2). The system call unit (21) inquires at an access determining unit (31), so as to confirm that the application (1) is allowed to access the device driver (22). After confirming that the application (1) is allowed to access the device driver (22), the system call unit (21) transfers the control instruction to the device driver (22). When a new device (4) is connected, the access determining unit (31) determines whether the application (1) is allowed to control the device (4).
