A system and method are proposed for estimating interconnect delay in an Integrated Circuit. Specialized algorithm is implemented to enhance multi-vector electrode sensing. The socket arrangement also secures the spacer element in an applied position. In the first position the circular projection generally occludes flow through the circular aperture, and in the second position the circular projection is adjacent to the circular aperture, providing a fluid flow path from the bottle, through the liquid flow aperture and the circular aperture. The code data are converted into area information and stored in a storage unit, from which particular area information is retrieved and transmitted to an on-vehicle navigation device by which a traveling route of the vehicle is established on the basis of area information to guide the vehicle to the destination.
