摘要： A system and method are disclosed for implementing a power source including a power amplifier that generates a radio-frequency power signal with an adjustable operating frequency. The power amplifier also generates a reference phase signal that is derived from the radio-frequency power signal. An impedance match provides the radio-frequency power signal to a plasma coil that has a variable resonance condition. A phase probe is positioned adjacent to the plasma coil to generate a coil phase signal corresponding to the adjustable operating frequency. A phase-locked loop then generates an RF drive signal that is based upon a phase relationship between the reference phase signal and the coil phase signal. The phase-locked loop provides the RF drive signal to the power amplifier to control the adjustable operating frequency, so that the adjustable operating frequency then tracks the variable resonance condition.

摘要： A pre-manufactured roofing panel includes a joint having a first and a second edge that form a locking joint. The first edge includes a longitudinal protrusion extending outwardly from first edge. The protrusion has a generally trapezoidal cross-sectional shape. The second end includes a longitudinal cavity. The cavity has a generally inverse trapezoidal cross-sectional shaped substantially corresponding to the size and shape of the protrusion. The unique shape of the protrusion and cavity greatly facilitates the alignment of the two edges and reduces the likelihood of damage to either edge. The panel also includes a ribbed gasket disposed along an outer edge that seals any voids created by imperfections in the panels. The gasket is installed at the factory, and includes a polyethylene foam gasket.
