The electric toothbrush includes the linear oscillator and a brush head attached to the shaft for use in brushing teeth.

Abstract: An orbital remover including a body assembly and a tip drive assembly. The body assembly includes a main spring. The tip drive assembly includes a tip holder, a bearing guide having a convoluted race formed on an inner surface, a bearing spring, and at least two ball bearings. The ball bearings are housed in the tip drive assembly between the bearing spring and the bearing guide within the convoluted race formed in the body assembly, and the depression of the body assembly in a vertical movement actuates the ball bearings within the convoluted race, thereby rotating a tip received in the tip holder in an orbital movement. The main spring provides resistance for and returns the tip drive assembly to a starting position after the body assembly is vertically depressed.
