A remote translation mechanism for a multi-node system. The image sensor also has an interconnect layer that is adhered to the convex surface of the core structure, and a photo-sensing layer that is connected to the interconnect layer. The auxiliary machine is driven by the generated power of a downwind type wind turbine to which a permanent magnet type generator is mounted and which generates power in a state in which a blade of the downwind type wind turbine rotating in response to the wind faces downwind.
