Semiconductor chips are provided. The present invention utilizes as well as extends the session initiation protocol to provide for domain hand-off and subnet hand-off so that users can access the network from any location using their own mobile station as they roam across different 3G-IP networks. The power monitor determines a power consumption number based on sampled signals within one or more functional blocks in the processor, rather than based on temperature. The relief layer is removed according to the pattern by laser or plasma radiation to form the multiple openings. Preferable embodiments of the current invention may utilize measurement of the viscoelastic property of die swell ratio, or other viscoelastic properties of cervical-vaginal fluid. The first and second moldboards move with respect to each other.
