A smart entry system and method includes at least one actuating device for operation of at least two vehicle functions, an on-board transmitter for sending request signals to a portable device, and an on-board receiver for receiving an identification signal from the portable device. The flotation machine foams hydrophobic particles from an aqueous slurry that contains these particles. Next, the system estimates capacitances for cells within the IC design based on analytic models of the cells. The spit holder is swivelable in vertical position or in horizontal position to enable the engagement of the chain wheel with the power chain, thereby rotating the positioning element to achieve an optimal barbecuing effect.
