A method for estimating channel parameters of radio channels of a W-CDMA mobile radio system, for example in accordance with the UMTS standard includes transmitting sequences of known symbols between unknown data symbols by a base station. The electrical device includes a bezel frame configured to fit within a faceplate. The interactions can include the use of the device, the use of one or more applications, andor other tasks, subtasks, or other operations. Points and penalties correspond to the selected responses. In one embodiment, each series of serpentine winding are separated by a gap so that they can be inserted on the stator disk from the edge. A conductive material is deposited in the TSV in electrical contact with the analog circuit.
