A method and a system to perform multi-model blending are described. Collinear first holes extend through the skirt at a first location along the skirt and collinear second holes extend through the skirt at a second location along the skirt spaced from the first location. A channel formed between each antenna group and a reception apparatus may have a relatively low correlation and thus, the may be assumed to be independent. The boost structures assists in programming so that the programming and pass voltage on a word line can be reduced, thereby reducing side effects such as program disturb. First and second feedback circuits monitor the state of the electrical load and provide status feedback to the microprocessor which is adapted for annunciating a fault condition. The top bead and side bead are integrally formed such that a force exerted on the side bead allows the side bead to cooperate with the top bead to properly seal an intake pipe within a cylinder head.
