Abstract: A cranial motion dental attachment for linking the interproximal walls of adjacent molded crowns while permitting relative movement therebetween. The attachment includes a piston having an integral retainer stem which is attached to a dental structure and a cylinder attached to an adjacent dental structure adapted to receive the piston so that the piston is moveable within the cylinder permitting horizontal or lateral movement between the adjacent dental pieces.

Abstract: The disclosed communication system enables communications between reconfigurable data terminals and a variety of connected computers, having dissimilar operating parameters, by automatically reconfiguring the operating parameters of the calling terminal to match those of the called computer. The system controller, in response to receiving the dialed number of the called computer from the calling terminal, accesses its memory for the operating parameters of the called computer and transmits these operating parameters to reconfigure the calling terminal. Another embodiment enables the operating parameters of a terminal to be reconfigured in any of a number of operating modes in response to a reconfiguration request signal sent to the system controller from the terminal.
