Abstract: A hub assembly for simultaneously mounting one or two vibrating devices has a central body portion, a first end portion adapted to removably connect to a first vibrating device, and a second end portion adapted to removably connect to a second vibrating device. The central portion has a control system for controlling power and function to the first and second vibrating devices mounted on the first and second end portions, a power level/function indicator display, and may have a power source adapted to provide power to both vibrating devices.

Abstract: A vibrator assembly comprises a control handle, a vibrator body, and an adaptor coupling. The adaptor coupling is adapted to interconnect the control handle and the vibrator body. The control handle and the vibrator body are not designed for direct interconnection to each other. Thus, the adaptor coupling enhances the versatility of the control handle and the vibrator body by allowing them to be used together. By employing a set of adaptor couplings, the control handle can be used with a set of vibrator bodies of different size or shape, with adaptor coupling being selectively useable to interconnect the control handle to the vibrator bodies on an interchangeable basis.
