A method, a system and a computer program product presents multimedia contents in elevator installations. The system receives either a point-to-point packet or a broadcast packet from the devices and inspects the header of the packet to determine the type of packet. The second thermal head, the second platen roller, and the second biasing means are in contact with a heat-sensitive layer of the thermal recording paper. The imaging apparatus images a predetermined operating element. The implant includes collagen and or other bio-resorbable materials, where the implant may also be used for therapy delivery.
