Abstract: Each time a time corresponding to one period of an intermittent reception process in a vehicle-side device elapses, a transmission interval of a notification signal is controlled so that a transmission time of a preamble of the notification signal is shifted in a direction in which the transmission time is relatively delayed from an execution time of the reception process. Further, when the transmission time of the preamble passes through a range of the execution time of the reception process during this relative shift, the transmission interval of the notification signal is controlled so that the entire transmission time of the preamble is included in the range of the execution time of the reception process.

Abstract: A travel lane line determining unit determines a travel lane line to be used based on a predetermined selection criterion, from among the travel lane lines. A determining unit determines whether or not the own vehicle is going to depart from the travel lane line based on the determined travel lane line. A departure preventing unit outputs an alarm or controls steering of the own vehicle towards a direction in which the departure is avoided, when determined that the own vehicle is going to depart from the travel lane line. A parallel-driving control unit controls steering of the own vehicle such that the own vehicle travels along the determined travel lane line. The selection criterion determines a travel lane line from the travel lane lines which do not correspond to a predetermined exclusion condition, according to an execution state of the departure preventing unit or the parallel-driving control unit.

Abstract: Methods and apparatus are disclosed for a self-directed (i.e., autonomous), steerable gravity-embedded anchor. This anchor free-falls through the water column, accelerates due to gravity and uses its kinetic energy to embed itself into the seafloor so as to function as an anchor for mooring of both floating vessels and other underwater structures. Unlike existing gravity-embedded plate anchors, this device can steer itself to its intended target location on the seafloor, enhancing placement accuracy and allowing release directly from an installation vessel on the water surface, thereby greatly simplifying installation.
