A ranging method in a mobile station of a femto system is disclosed. Decisions are made on how to select or combine the outputs of the noise estimators into a usable noise estimate, based on an occlusion function. A second file including object code therein and further including object file summary information is accessed. Each arm includes a root end and a free end, and has a first connecting member thereon that is configured for connecting the construction toy element to another construction toy element. The control unit and the temperature-influencing unit control the temperature of the binding material of the gradient coil system to a value above the glass temperature during operation of the MRI system. The piezoelectric bulk wave device utilizes the thickness shear mode of the piezoelectric thin plate made of LiTaO3, and of the Euler Angles of LiTaO3, \u03c6 is 0\xb0, and \u03b8 is in the range of not less than 54\xb0 and not more than 107\xb0.
