  • Patent number: 8600129
    Abstract: An ultrasonic volume data processing device which forms a three-dimensional image of a target tissue in a living body is provided. A range in which a rendering process is applied is limited by a three-dimensional region of interest (3D-ROI). The three-dimensional region of interest has a clipping plane as a rendering start surface. A shape of the clipping plane can be deformed into a convex shape or a concave shape by a user operation, and the clipping plane may be freely inclined in two-dimensional directions. With this configuration, for example, the clipping plane can be suitably positioned in a gap between a face of a fetus and a placenta. When the curved clipping plane is used, a striped pattern noise tends to be formed in the three-dimensional image. In order to resolve or reduce the striped pattern noise, a special voxel calculation is applied to a final voxel of each ray in the voxel calculation for each ray.

  • Patent number: 8600657
    Abstract: According to conventional art, if there is an obstacle on the left of a vehicle, a control threshold value is set so as to avoid the obstacle. If the control threshold value is exceeded, the vehicle is controlled in accordance with a deviation quantity so as to return to a position where the control threshold avoids being exceeded. However, even if a risky oncoming vehicle is approaching the vehicle on the right, the vehicle is controllably moved toward the oncoming vehicle. Thus, disadvantageously, a driver has a sense of fear or discomfort.

  • Patent number: 8601161
    Abstract: An address translator includes an SIP message detecting function. Upon detection of an SIP message, the address translator sends the SIP message to an SIP address translator. The SIP address translator extracts addresses for translation, and makes a query to the address translator. The SIP address translator translates an IP address included in the SIP message, using translation information of the address translator. Thus, an SIP communication is accomplished between terminals belonging to different regions in association of the address translator and the SIP address translator.

  • Patent number: 8601319
    Abstract: A technique determines which configuration change(s) caused an application invocation failure of a computer application without the need for a knowledge database. To determine which configuration change is the most likely cause, the cause analysis program checks other computers that have experienced the same configuration changes. The cause analysis program checks and counts the application invocation results before and after each configuration change is done. If the same configuration changes are found in the other computers, the program checks whether each configuration change caused or cured the same problem in that computer. The program counts the similar cases for all of the computers. Subsequently, the program calculates the ratio of those instances involving a change from success to failure and the ratio of those instances involving a change from failure to success out of all instances for each configuration change.
