A microwave oven food & drink enclosure assembly for keeping the insides of the microwave oven clean from splatters. The orientation is selected such that a first permittivity parallel to the gate insulation layer is significantly less than a second permittivity perpendicular to the gate insulation layer. The exposed portion is provided for direct physical contact with a second conductive trace exposed at an edge of a second substrate. The SOA includes gain and polarization rotation functions integrated onto a single substrate. The connecting piece and the guide surfaces form bearing surfaces for balls of the ball bearing arrangement where the bearing surface of at least one of these components\u2014connecting piece and housing \u2014can be elastically deflected transversely to the bearing surface and clamps the balls free of play between the bearing surfaces. The cradle for the mobile phone of the invention is to be used with a scanner remote controller that reads a printed dot pattern, in which information is recorded, and transmits the information.
