A laser communications and position location system has a laser transmitter with a laser array radiating modulated laser beams upward at convergence angles that determine altitude of a free space junction where the beams converge. The auxiliary coupling disk further can alter the vibration of the motor. A user is presented with a second training session associated with a different learning strategy based on the determined effectiveness of the first learning strategy. A destination device is in communication with the port at the aggregation device. The light-transmissive portion of the body extends to a window in the side surface or the front face. The mechanical fastening system preferably comprises a tape tab having a first fastening element, a landing member comprising a second fastening element engageable with the first fastening element, and disposal mechanism for allowing the absorbent article to be secured in a configuration that provides convenient disposal of the absorbent article.
