  • Publication number: 20140211007
    Abstract: An object detection circuit detects an object moving in a periphery of a vehicle by use of a shot image. A state judgment part changes a parameter relevant to a detection function so as to change whether the detection function of the object detection circuit is to be enabled or disabled while the object detection circuit is kept activated. Thus, even when the detection function of the object detection circuit is disabled, the object detection circuit is kept activated. Therefore, since there is no need to restart the object detection circuit in order to enable the detection function of the object detection circuit, a detection result by the object detection circuit is promptly obtained.

  • Publication number: 20140214896
    Abstract: A first memory stores requester event records describing events that occurred in relation to processes executed in a first server. A second memory stores requestee event records describing events that occurred in relation to processes executed in a second server in response to execution requests issued from the first server. An associating unit searches the first and second memories for requester event records and requestee event records whose transaction identifiers are identical and associates the found records together. A determining unit compares the associated event records with each other in terms of their time information. Based on this comparison, the determining unit determines a correction value for correcting time differences between requester event records in the first memory and requestee event records in the second memory.
