  • Publication number: 20240123619
    Abstract: In a case in which a second distance between a future position of a robot and a future position of a person is shorter than a second predetermined distance, a modification unit modifies movement trajectory information such that the second distance is equal to or longer than the second predetermined distance. In a case in which a first distance is shorter than a first predetermined distance, a control unit stops or decelerates a movement of the robot, regardless of whether the movement trajectory information is modified. In a case in which the first distance is equal to or longer than the first predetermined distance and the movement trajectory information is modified, the control unit controls the movement of the robot on the basis of the movement trajectory information after modification.

A set of title scores may also be generated for a media item based on a title-content score model, where each generated title score represents an affinity between the media item and a corresponding content type. In response to a request, the sets of scores may be combined to generate a set of content recommendations to provide to the requestor.

  • Publication number: 20240103213
    Abstract: A multi-core optical fiber comprises at least two (2) helical cores. When the multi-core optical fiber is bent, such that it has a bend length (L) and a bend radius (R), each core experiences a different strain, thereby resulting in an effective optical length difference (?l) between the cores. In the present disclosure, the helical cores have a pitch (P) that reduces ?l/L to a value that is less than 5·10?6 (i.e., ?l/L<5·10?6).
