A massager has a rotation shaft with arcuate grooves defined in a periphery of the rotation shaft and a guide received in the arcuate grooves so that when the rotation shaft rotates, the guide is able to control the rotation shaft to rotate and extend. For this purpose, the threaded nut and the force transmission element are connected to one another by means of a positively locking, in particular play-free connection, in particular by means of clinching. The tongue may be in the form of a laminate consisting of a pair of substantially inert outer layers sandwiching a high shrink inner layer. The compounds, compositions, and methods of the invention are also useful for inhibiting the replication andor infectivity of a virus. The speech recognition system is adapted to receive attribute data verbalized by an operator of the mobile data terminal.
