Methods and apparatus are provided for decimated interpolated clockdata recovery to perform asynchronous sampling of a received signal. With the use of the Fresnel lens sheet and the rear projection screen in accordance with the present invention, a labyrinth light inside the screen and a surface reflection are diffused effectively and a ghost caused by them is remarkably reduced. Once the virtual phone image has been downloaded, the management service component initiates a periodic attempt to establish a connection with the mobile management server to comply with the downloaded security-related policy settings. The two materials are then co-fired together, with the relative amount of shrinkage between the two materials during the firing step being affected by the amount of pre-shrinkage of the CMC material during the bisque firing step.
