Abstract: An electric periodontal massager having a housing and a first shaft rotatably disposed therein about an axis. An electric motor is provided for rotating the shaft and a crank is disposed on the other end of the shaft. A second shaft having a rubber or resilient massaging tip thereon is provided for periodontal usage. The other end of the second shaft is resiliently attached to the housing. A resilient linkage has one end thereof attached to the crank of the first shaft and the other end thereof disposed around an intermediate portion of the second shaft whereby rotation of the first shaft by the electric motor causes the first end of the second shaft and thereby the resilient massaging tip to move for applying chemicals to and massaging gum tissue.

Abstract: A portable, hand-held data telecommunications terminal for use with a telephone system having a memory for storing data, a signal generator for generating signals corresponding to the data, a signal coupling device connected to the signal generator for coupling the signals to the telephone system, a keyboard, a microprocessor, and a self-contained power supply. The microprocessor is connected to the memory, the signal generator and the keyboard device so as to control, under the direction of the keyboard, the receipt of data from the keyboard, the storage of the data by the memory, and the generation of the signals by the signal generator. Data is entered into the memory from the keyboard device so that the data is available at a future time, to be coupled to the telephone system.
