A substrate bearing, on one main face, a composite electrode, which includes an electroconductive network which is a layer formed from strands made of an electroconductive material based on a metal andor a metal oxide, and having a light transmission of at least 60% at 550 nm, the space between the strands of the network being filled by an electroconductive fill material. The impeller has an opening extending in an axial direction and a stem with an outer surface having a tapered profile in a cross section including the axis and a non-circularly symmetric profile in a cross section perpendicular to the axis. Each of the plurality of tubes is configured to hold a fishing rod and, alternately, a sun umbrella. When defining the directions along the first section in the concave portions 28b1, 28b2 as axis directions L1, L2, each of the axis directions L1, L2 are not parallel with the arrangement direction, and the axis directions L1, L2 are set to two or more directions. The finger-receiving scoop extends from the underside of the lid into the container. The gateway includes circuitry to obtain data relating to the device, to transmit the data to a server, and to receive configuration information from the server that is generated based on the data.
