Abstract: A vehicle positioning system includes a first-vehicle information receiving unit, a surrounding information analysis unit, a positioning unit, a positioning accuracy determination unit, a second-vehicle information generation unit, and a second-vehicle information transmitting unit. The first-vehicle information receiving unit receives first-vehicle information from a first vehicle around a second vehicle. The surrounding information analysis unit analyzes the first-vehicle information to acquire a first positioning performance. The positioning unit performs positioning of the second vehicle based on satellite information and the first positioning performance. The positioning accuracy determination unit determines accuracy of the positioning of the second vehicle.

Abstract: Apparatus and method to clearly indicate a region in which a bubble based on therapeutic ultrasonic waves is occurring. A controller acquires reception signals based on an ultrasonic waves that have been transmitted from an ultrasonic probe at differing phases and timings, reflected by a biological tissue, and received by the ultrasonic probe. The controller adds the reception signals to generate a higher harmonic reception signal. The controller acquires a fundamental wave reception signal, which is one of the reception signals. The controller determines a comparison value which represents the difference between the value of the higher harmonic reception signal and the value of the fundamental wave reception signal. The controller determines, on the basis of the comparison value, whether a processing target pixel indicated by the higher harmonic reception signal or the fundamental wave reception signal indicates a cavitation region or a normal region.

Abstract: A control device in one aspect of the present disclosure includes a vehicle information acquisition unit, an obstacle information acquisition unit, and a sudden braking detection unit, and controls a warning information transmission unit to transmit, to an other vehicle, warning information including obstacle information when a sudden braking is performed by a subject vehicle. When receiving the warning information from the other vehicle, a target vehicle determination unit confirms that the other vehicle is a warning target vehicle, and a risk calculation unit calculates a collision risk of the subject vehicle to collide with an obstacle, and a collision avoidance unit performs a collision avoidance control according to the calculated collision risk.

Abstract: A fall damage reducing system includes a flying device and a vehicle-mounted device. The flying device: performs a wireless communication under a vehicle to vehicle communication standard; determines a falling possibility of the flying device; and transmits falling information indicating an estimated falling position of the flying device in response to the falling possibility being determined. The vehicle-mounted device: performs a wireless communication under the vehicle to vehicle communication standard; executes a vehicle control on a subject vehicle to avoid the estimated falling position in response to the falling information being received; and transmits traveling information indicating the vehicle control executed on the subject vehicle. In response to the traveling information from a different vehicle being received, the vehicle-mounted device executes a collision avoidance process to avoid a collision with the different vehicle.

Abstract: Target point cloud data about a specific road are extracted from perimeter point cloud data acquired by moving a road surface measurement device along a measurement route and scanning the surroundings thereof. A data storage unit stores trajectory point sequence data that represent, as a plurality of trajectory points, the perimeter point cloud data and a trajectory of the movement of the road surface measurement device. A trajectory point sequence setting unit acquires a trajectory point sequence at equal intervals from the trajectory point sequence data. An extraction area setting unit sets, as extraction areas, a column area Ci and a parallelepiped area Hi that are geometric areas disposed at predetermined positions below a trajectory point Xi. An approximate nearest neighbor search processing unit and an extraction processing unit extract, as the target point cloud data, point data that belong to this extraction area of the perimeter point cloud data.

Abstract: A micro movable mechanism system includes a micro movable mechanism. A target position generating section generates a signal indicative a target position of the micro movable mechanism. A nonlinear control unit outputs a controller output signal indicating a control value based on a difference between the target position signal and a signal indicating a current position of the micro movable mechanism. A root correction section drives the micro movable mechanism based on a signal proportional to a square root of the control value.
