The invention relates to a lubricant composition based on modified, natural and renewable raw materials, the viscosity of which can be adjusted according to the application. The voice coil assembly is comprised of a tubular former with insulation coated, electrically conductive wire, an air filter, a vent plate, a ring with radial channels and parallel walls, a front plate, a magnet, and a back plate. The outer wall surrounds the inner wall and the inner wall surrounds an inner cavity of the apparatus. The receiver analog circuitry receives an RF signal and processes the received RF signal to generate a digital signal. The plurality of link layer controllers may be configured to operate independently in a first mode and cooperatively in a second mode.
