Abstract: Efficient audio/video data storing is proposed. An audio/video stream is recorded in a shared storage zone on behalf of a plurality of client processes or client devices. Recording in the storage zone is managed through a reservation based method. Client processes and client devices may read access a recording stored on their behalf until the client process or client device releases its reservation. When a client process or client device releases its reservation, at least some of reserved storage space in the storage zone may be freed for reuse by other client processes or client devices, if the reserved storage space is not part of a reservation by another client process or client device.

Abstract: The invention relates to a positioning and immobilization device for positioning and immobilizing a mandibular or maxillary surgical guide on a patient, which guide is adapted to preparing for and to fitting at least one dental implant and is provided with a link slab member designed to extend outside the oral cavity when the surgical guide is placed in register with the patient's mandible or maxilla, said positioning and immobilization device being characterized in that it comprises a body that has bearing face for bearing against the outside of the head of the patient, and a fastener designed to co-operate with the link slab member of the surgical guide.
