A device for connection 3 of a battery 2 to an electric or hybrid motor vehicle, comprising at least one input 3a capable of being connected to a first terminal 2a of the battery and at least one output 3b capable of being connected to a first terminal of an electrical circuit of the vehicle. The ribs align with conductive surfaces inside the handpiece that make contact with an internal flexible electronic circuit to activate the device when force is applied to the ribs. The rate of change of the phase of the complex coefficient is determined by a phase-lock loop coupled to the adaptive filter to adapt a dynamic incident frequency corresponding to a single frequency component of interest in the primary signal. Based upon how the identified resource matches one or more rules, the node will determine whether the resource access request is redirected through the virtual private network or handled locally. A step of forming the first conductive film includes the steps of forming a lower conductive layer made of a noble metal other than iridium over a first interlayer insulating film; and forming an upper conductive layer made of a conductive material, which is different from a material for the lower conductive layer, and which is other than platinum.
