  • Patent number: 9031730
    Abstract: A power demand management apparatus comprises a schedule holding section that holds a power restriction schedule indicating a device on which a mobile robot is to perform power restriction, in association with a power restriction execution time; a movement instructing section that transmits movement instructions to the robot such that, prior to the power restriction execution time indicated in the power restriction schedule, the robot moves to an area in which is arranged the device on which the power restriction is to be performed at the execution time; and a restriction instructing section that transmits power restriction instructions to the robot, thereby causing the robot to perform the power restriction on the device at the execution time.

  • Patent number: 9030929
    Abstract: Network repeaters which each implement a redundant switching function previously grasp connection states of ports of a network system by using an inquiry frame and an exchange frame. At the time when a line is broken, when actively confirming a state of a port connected to a port in which a line is broken via a downstream device, the network repeaters each grasp that which portion of the line is broken and determine whether a switchover is required. Through the process, the network repeaters each prevent a useless switchover such as switching-back immediately after the switchover, and at the same time since a mechanism of waiting for a given length of times is not required, they each perform a fast switchover.

  • Publication number: 20150009216
    Abstract: An information processing apparatus that functions as non-liming example image processing apparatus includes a CPU that performs an updating process of a determinant for producing a shadow map in parallel with production and display processing of image data. In the updating process of the determinant, even in a case where an imaging range of a virtual camera is changed or a direction of a light from a light source is changed, if and when a changing amount of the imaging range of the virtual camera from a time that the determinant is previously calculated (updated) is less than a predetermined amount and a changing amount of the direction of the light from the light source from that time is also less than a predetermined amount, the determinant is not updated.

  • Patent number: 8582599
    Abstract: A translator for coupling a first IPv4 network and a second IPv6 network having different addressing architectures for IP addresses so as not to exhaust the IP addresses of one of the two networks, a network system using the translator, and a network coupling method. When a packet is transferred from the IPv6 network to the IPv4 network, the translator assigns any of previously prepared IPv4 addresses to an IPv6 address stored in a source storing field of the IPv6 packet. The assigned address is stored in a source storing field of an IPv4 packet. A packet translation unit assigns the foregoing IPv6 address to an IPv4 address stored in a destination storing field of the IPv4 packet, when a packet is transferred from the IPv4 network to the IPv6 network, and stores this address in a destination storing field of the IPv6 packet.

  • Patent number: 8469811
    Abstract: An information processing apparatus calculates or obtains inclination data which changes in accordance with the inclination of an input device, from the operation data obtained from the input device. The operation data includes at least one of data on a taken image taken by the imaging means, data representing predetermined two positions in the imaging target in the taken image, data representing a direction connecting the two positions, and inclination data representing an inclination of the input device which is calculated based on the direction. The information processing apparatus replaces an object (panel, etc.) displayed on a screen with another object based on the inclination data and displays the replacement result.

  • Patent number: 7957405
    Abstract: A packet communication method and a packet communication system capable of making an IPv4-compatible application operating on an information processing apparatus communicate with another information processing apparatus connected to an IPv6 network without using an address translation router. In the information processing apparatus connected to the IPv6 network, an IPv4-to-IPv6 protocol conversion control function is incorporated in a LAN driver. A protocol conversion control module receives an IPv4 packet from a protocol control module. When a send destination IPv4 address contained in a header of the packet is registered in an address translation table incorporated in the protocol conversion control module, an IPv6 address is generated to be sent onto a LAN. Unless the send destination IPv4 address contained in the packet header is registered in the address translation table incorporated in the protocol conversion control module, the IPv4 packet as received is intactly sent onto the LAN.

  • Patent number: 7835341
    Abstract: A packet communication apparatus sends an authentication request packet received from a user terminal to an authentication server. If a packet received from the authentication server is an authentication packet for the user terminal, an authentication controller executes authentication processing of the authentication packet. If the authentication packet includes connection limit information for the user terminal, a connection limit controller sets the connection limit information to the user terminal. According to the connection limit information, the packet communication apparatus sends the packet received from the user terminal to a quarantine server disposed to quarantine the user terminal.
