Abstract: A virtual reality (VR) system for providing engagement of a super actor with a plurality of user actors and enabling interaction and collaboration between the user actors in association with interactive content in a VR environment. A processing system provides logic and control operations, networking functionalities and content management services directly to the super actor and user actors within a group and the particular interactive content associated with that group. Each of the devices are configurable to activate a package comprising data technically describing one or more discrete virtual worlds. This data comprises a prescribed array of items corresponding to different item types, where each virtual world is customised with items to provide prescribed functionality to the particular actor and to the particular content to be associated with the virtual world.

Abstract: A new and improved anatomical imaging system which includes a new and improved movement system, wherein the movement system comprises an omnidirectional powered drive unit and wherein the movement system can substantially eliminate lateral walk (or drift) over the complete stroke of a scan, even when the floor includes substantial irregularities, whereby to improve the accuracy of the scan results and avoid unintentional engagement of the anatomical imaging system with the bed or gurney which is supporting the patient.
