An apparatus for detecting the dart in a barrel of a toy gun is provided. The mobile radiotelephone provides access to a radio communications network managed through a management center. Next, the system facilitates the electronic transaction between the entities by notifying one or more of the entities of the shared electronic transfer capabilities. The one or more motors may be configured to control a crossflow blower arranged to generate a flow of air in a direction substantially perpendicular to an axis of rotation of the crossflow blower. The spring and lever are aligned so they toggle, enabling the clutch to remain either engaged or disengaged with no additional controls. The LCD comprises a color filter substrate, an array substrate disposed opposite to the color filter substrate, and a liquid crystal layer sealed between the two substrates, wherein a conductive nano-particle is introduced between the two substrates.
