Oral delivery systems including at least one encapsulated active are provided. The method comprises: forming a gate, having vertical sidewalls and a top surface, overlying a substrate insulation layer; depositing a silicon oxide thin-film gate insulator overlying the gate; plasma oxidizing the gate insulator at a temperature of less than 400\xb0 C. A total concentration of the reactive components within the gas is less than 4. The conductor spool may be included in a wire harness and conductor spool assembly, the conductor spool seated upon a conductor lead furcated from a composite cable including at least one optical and at least one electrical conductor. A support area of the vane contacts the circumferential surface of the basic body when the vane exerts a force on a note of value. When operating in the pulse mode, the inverter generates a sinusoidal output pulse waveform including a plurality of pulses having a determined pulse width.
