A method and a small profile apparatus for generating high voltage impulses. An antenna rod can be stopped at a predetermined angle position via a hinge mechanism. The compositions may be utilized to treat ophthalmic, otic and nasal conditions by topically applying the compositions to the affected tissues. Additionally, the internal structure or spatial variation of composition of the dosage form is preserved during the pressing operation, with geometric shrinkage occurring mostly in the direction of the axis of pressing. One side of the cable connector is affixed to the chassis base and the other side of the cable connector is coupled to one of the substrate connectors and to at least an end of the wiring member.
