Abstract: Some embodiments are directed to a method for dynamic display of objects of a virtual world to a user associated with an observer located within the virtual world, including the observer, determining a first octree structuring the virtual world, and constituting a first partition based on this octree, and a set of subscriptions to each cell of the partition Determining for each object a container to which it is attached. Determining, for each container and for said observer, a second octree structuring the container, and constituting a second partition based on said second octree, and a set of subscriptions to each cell of this partition. Defining for each object, columns comprising a hierarchy of nodes determined by a height parameter. Each of the objects publishing events associated with each nodes of the column with a frequency decreasing with its height.

Abstract: A control device for a mobile robot, the robot comprising a camera and a communication unit, comprises a display unit displaying an image corresponding to the image taken by the camera and transmitted by the communication unit, and a user interface, wherein the user interface is configured to allow a user to control a position of a pointer on the image displayed by the display unit, and the user interface comprises a selection unit allowing the user to select a position of the pointer on the image displayed by the display unit, the control device further comprising a computation unit and a communication system, the computation unit being configured to compute displacement commands and send them through the communication system to the robot, said displacement commands being computed to make the robot move to a physical position corresponding to the pointer's position selected by the user on the image.

Abstract: A roller bearing according to an embodiment comprises a first roller bearing ring comprising at least one raceway, a second roller bearing ring comprising at least one raceway, a plurality of rolling elements arranged between the raceways of the first roller bearing ring and the second roller bearing ring and at least one retaining flange detachably mounted onto the first roller bearing ring. Employing an embodiment may simplify at least one of manufacturing and assembling the roller bearing.

Abstract: The invention concerns a method to produce a cage (1) for a rolling bearing (40), wherein the method comprises the steps of; —(10): providing an elongated metal profile (1) comprising a first and second distant ends (12, 13), wherein the metal profile (1) is essentially ring-shaped, —(20): subsequently joining the first and second ends (12, 13) of the metal profile (1) to thereby form a closed ring (1), —(30): forming in the closed ring (1) a plurality of openings (14) on at least one axial side face of the ring (1), wherein the openings (14) are meant to receive at least one rolling element (43) of the rolling bearing (40), and wherein the forming of the openings (14) is made by drilling from the axial side face of the ring (1). Furthermore, the invention regards a cage (1) and a rolling bearing (40).

Abstract: A bearing component comprising a first cage cup formed from at least one first element configured to receive rolling elements. The bearing component further comprises a first flange formed from at least one second element and connected to a periphery of the first cage cup.
