The present invention provides a lamp unit for low beam, a lamp unit for high beam, and a lamp unit for shoulder edge beam. Each electrode configuration represents a polarity or a polarity percentage of the electrodes of an electrode array. Also, this method provides a quad-tree block segmentation method using the Greedy algorithm by which the transmission rate-distortion performance of motion compensation is improved. The domed top over the solar panel improves the solar panel’s ability to capture light and thus to operate in locations where the incidence of light is at a low angle as is found in northern latitudes. In the communications mode the user speaks into the switch and receives responses at the switch.
