A convex forward surface of a forward-biased probe head of a first portion of a docking system engages a central concave conical surface of a second portion of the docking system. The collapsible reel comprises a core, around which a flexible media is wound, and flanges which prevent the wound flexible media from migrating axially off of the core. Special triglycerides are derived from branched aliphatic acids having alkyl chains with average carbon numbers from 6 to 9 and at least 10% methyl branching. The loading and interleaving operations are repeated N times before the results, stored in the vector registers, are written back to memory. A second number of the series of second values is then averaged to obtain a gain error of the target stage. The supporting shelf has an adjustable viewing angle for adjusting the viewing angle of the LCD TV.
