A portable electronic device including a first section, a second section and a connecting section. The multilayer film base comprises a multilayer structure, in which a tie layer comprises a PET-based polyester material having a specified amount of monomeric units derived from 1,4-cyclohexanedimethanol, such that the support layers of the multilayer film base does not delaminate. The stamped metal ring has a flat inner section with a central circular opening with the inner edge beaded inwards and an elevation to form an upper bed and a peripheral edge turned downwards so that, jointly with the peripheral portion of the membrane it can be beaded in the container. The computer is configured to calculate a first value indicative of vehicle stability at a first predetermined time based on the plurality of signals. The fingers are preferably deformed into a state of bending. This allows to drive the vehicle using only the internal combustion engine.
