A contact-less high-speed signaling interface and method provide for the communication of high-speed signals across an interface, such as a die-substrate interface or die-die interface. The switch is securely mountable at a fixed mounting position on a frame of the vehicle, and the magnet is directly and securely mountable on a translatable portion of a user actuator for shifting the transmission. The radiating elements of succeeding layers are vertically aligned with conductive vias extending through the substrates to connect the radiating elements to the ground plane. Finally, it uses the comparison result to determine if booting the computer is permitted. A book database can be generated based on images of books. Due to the above configuration, the membrane having flexibility mitigates a rapid pressure change in the manifold caused by backflow of ink, and thus, cross-talk between adjacent pressure chambers during ink ejection can be effectively prevented.
