Abstract: Social interactions between two or more users in a mixed reality environment are described. Techniques describe receiving data from a sensor. Based at least in part on receiving the data, the techniques describe determining that an object associated with a first user that is physically present in a real scene interacts with a second user that is present in the real scene. Based at least in part on determining that the object interacts with the second user, causing virtual content corresponding to the interaction and at least one of the first user or the second user to be presented on a user interface corresponding to a mixed reality device associated with the first user. The user interface can present a view of the real scene as viewed by the first user that is enhanced with the virtual content.

Abstract: Techniques for enabling two or more remotely located users to interact with one another and for causing virtual content that corresponds to individual users of the two or more users to augment virtual representations of the individual users in a remote communication environment is described. A service provider can receive image data and tracking data associated with a first user corresponding to a first device. Further, a service provider can cause a virtual representation of the first user to be presented on a display of a second device corresponding to a second user, determine an interaction between an object associated with the second user and the virtual representation of the first user, and based at least in part on determining the interaction, cause virtual content to be presented on the virtual representation of the first user on at least the display.

Abstract: A universal joint includes a first joint yoke and a second joint yoke having respective base portions. Each of the joint yokes has two yoke arms that are attached on the respective base portions. Each of the yoke arms ends in a free end and has an inner face facing toward the longitudinal axis and an outer face facing away from the inner face. Each of the yoke arms has a bearing bore extending between the outer face and the inner face. The inner face of each of the yoke arms has a first recess that is open toward the free end and that ends in the corresponding bearing bore. A journal cross assembly includes a journal cross having four circular cylindrical trunnions arranged at right angles toward each other, each trunnion supporting a bearing bushing having a cylindrical envelope face and a cylindrical bore. The bearing bushings are supported on the trunnions by rolling members.

Abstract: A universal joint includes two joint yokes that, respectively, have two yoke arms that each start from a connection portion. Through an eye portion distanced from the connection portion, bearing bores extend in which respectively, a journal of a journal cross by means of interposition of rolling members and of a bearing bushing are supported. On the outside of the yoke arms, a bulge is respectively provided towards the connection portion and adjacent to the bearing bore and over a partial circumference of the same, which bulge has, towards the bearing bore, a groove. A circumferential groove, belonging to a retaining trunnion projecting from the base of the bearing bushing, is arranged opposite to the groove. Between the two, a securing element is arranged that engages with an engagement portion in the groove and with a retaining portion facing away from the same, in the circumferential groove of the retaining trunnion.

Abstract: The invention relates to a fluid delivery device for shafts, with a shaft-ring section assigned to the shaft, which rotates with the shaft during rotation of the shaft and a ring body arranged around the shaft ring section, fixed during rotation of the shaft, which has an inlet for the fluid, rolling bodies being arranged between the shaft ring section and the ring body, on which the shaft ring section and the ring body are supported and a passage being assigned to the shaft ring section, which is connected to inlet.
