  • Patent number: 11949322
    Abstract: A power conversion device includes a first control device to an m-th control device that are capable of communicating with each other. A k-th control device transmits specific information to control devices other than the k-th control device among the first control device to the m-th control device. The specific information includes voltage values of a plurality of unit converters included in a k-th cell set in each of a first arm to a third arm. From each control device other than the k-th control device among the first control device to the m-th control device, the k-th control device receives specific information including the voltage values of the plurality of unit converters. The k-th control device calculates a phase representative value of the voltage values of the plurality of unit converters included in each of the first arm to the third arm.

  • Patent number: 8599357
    Abstract: A photolithography system has at least one spatial light modulator, a scanning mechanism configured to move an exposure area relative to a target object in a scanning direction, a plurality of memories (1st to Nth memories), a data processor, and exposure controller. The exposure area is defined as a projection area of the spatial light modulator. The plurality of memories corresponds to a plurality of partial exposure areas that is defined by dividing the exposure area. The data processor successively writes exposure data into each memory in accordance with the timing of an exposure, and the exposure controller controls the plurality of light modulating elements on the basis of the relative position of the exposure area. The data processor writes newly generated exposure data into the first memory, and shifts exposure data stored in the 1st to (N?1)st memories to the 2nd to Nth memories, respectively.

  • Patent number: 8510456
    Abstract: In a connection device connected to a network mounted in a boat, a protocol of a connection device connected to a network mounted in a boat is identified based on a communication ID in a certain message transmitted through the network. A device protocol is determined in accordance with the protocol of the network. Data communication in the network is performed in conformity with the device protocol. Accordingly, when the connection device is connected to the network, the connection device automatically identifies a protocol of the network and operates appropriately. Therefore, upward compatibility is maintained and usability is improved.

  • Patent number: 8307216
    Abstract: In a device authentication control method and device, when a connection device is connected to a network mounted on a boat, it is determined whether or not the connection device corresponds to an authentication-free device. If the connection device does not correspond to an authentication-free device, an authenticating action is performed on the connection device. If the connection device does correspond to an authentication-free device, the connection device is exempted from the authenticating action. In this way, when a connection device does not correspond to an authentication-free device, an authenticating action is performed, but when the connection device corresponds to an authentication-free device, the connection device is exempted from an authenticating action. As a result, it is possible to handle specific connection devices as authentication-free.
