A registration method whereby a sensor-based approach is used to establish initial registration and whereby upon the commencement of navigating an endoscope, image-based registration methods are used in order to more accurately maintain the registration between the endoscope location and previously-acquired images. The energy required for triggering is transmitted in an electromagnetic manner. The increased thermal mass and thermal conductivity of the electrode design are achieved with a substantially solid electrode body with thick walls. The vehicle includes the engine, a damper assembly, the transmission, and the controller.
