Abstract: A method for managing virtual objects (O) corresponding to real objects (R), said virtual objects (O) comprising a set (OP) of information or data representing said real object (R), said virtual objects (0) residing in a management system (20), which comprises a computer system (21) accessible by user terminals (13) through a telecommunication network to enable operations to be carried out on said virtual objects (O) in a database (22a) in said computer system (21), said method comprising the operations of: generating (100), in response to a request of a requesting subject (C) to create one or more virtual objects (O) that represent respective real objects (R), corresponding unique identifier codes (Z, zx, c, i) that enable a user terminal (13) to carry out operations on the respective virtual object (O).

Abstract: A wheel bearing is provided with a sensor device for ABS systems, wherein a support ring for a sensor coupled is rotationally movable and is releasably secured by a groove in the bearing race from the axial movement. At initial installation the unit is placed on the bearing seat, pressing the support ring into predetermined axial position on a cylindrical surface of the axle member. In operation any creeping of the bearing race will cause no damage, and when the bearing is replaced the support ring with sensor remains in place on the axle member.
