  • Patent number: 12240451
    Abstract: In a driving assist apparatus which carries out a collision avoidance assist that is an assist for avoiding a collision of a self-vehicle and a collision risk object that is an object judged to have a high possibility to collide with the self-vehicle when the collision risk object is judged to exist, an object which does not exist in an object detection range of a front side radar and whose predicted running locus and a predicted running locus of a self-vehicle intersect at a position within a predetermined distance from the self-vehicle on the front side of the self-vehicle is selected as a target of judgment of a possibility to collide with the self-vehicle based on information acquired by the front lateral side radar, among the objects detected by the front lateral side radar.

  • Patent number: 11938930
    Abstract: A vehicle control apparatus selects, as a first group, objects in a predetermined area from objects included in object information, selects, as a second group, an upper limit number of the objects from the first group in descending order of a priority value when the number of the objects of the first group is greater than the upper limit number, and executes a collision avoidance control when an index value satisfies a predetermined condition. The priority value represents a probability that the own vehicle collides with the object. The apparatus reduces the priority value of a particular object of the first group when the moving speed of the own vehicle is equal to or lower than a moving speed threshold. The particular object is an object which is deemed to have a moving speed lower than a moving speed of a four-wheel vehicle.

  • Patent number: 11887221
    Abstract: System for image correction in PET is provided. The system may acquire a PET image and a CT image of a subject. The system may generate, based on the PET image and the CT image, an attenuation-corrected PET image of the subject by application of an attenuation correction model. The attenuation correction model may be a trained cascaded neural network including a trained first model and at least one trained second model downstream to the trained first model. During the application of the attenuation correction model, an input of each of the at least one trained second model may include the PET image, the CT image, and an output image of a previous trained model that is upstream and connected to the trained second model.

  • Patent number: 11618382
    Abstract: An alert apparatus sets a determination area which is at a turning direction side of an own vehicle with respect to a longitudinal direction line of the own vehicle and extends forward from the own vehicle or from near the own vehicle when an angle condition that a moving direction angle corresponding to an angle defined by a longitudinal direction line of the own vehicle and a moving direction of an approaching vehicle is within a predetermined angle range, is satisfied. The alert apparatus sets the determination area which is at the turning direction side of the longitudinal direction line and away forward from the own vehicle by a predetermined distance when the angle condition is not satisfied.
