Buccal aerosol sprays or capsules using polar and non-polar solvent have now been developed which provide diazepam for rapid absorption through the oral mucosa, resulting in fast onset of effect. The method utilizes an ink jet printing system to apply graphic designs over an uncured base coat of paint on the vehicle surface followed by the application of a protective clear coat over the graphic design. Alternative embodiments also enable tying of balloons while reducing the risk of leaking. Methods of manufacture using solid freeform fabrication techniques such as three-dimensional printing are described. In response to a control voltage, the VIC generates a control current for setting each operating current of the ring oscillator.
