A humidification system for a fuel cell includes a humidifier having a bundled plurality of tube type hollow thread members made of a water permeable membrane. The group III-nitride light emitting device comprises a lower n-type clad layer, a current spreading layer, an upper n-type clad layer, an active layer and an p-type clad layer formed in their order on a substrate. The speedup system performs many of the pre-calculations once, at the server, so that the bandwidth needs are reduced and the client’s computational load is minimized. After measurement, individual animals are sorted by direction of the computer in response to calculations from the measurements. Various embodiments further relate to a corresponding method for operating at least one discharge lamp. The bus bar is connected, via a conductive wire, to an object to be connected, which is provided at a position separate from the connection terminal in the extending direction of the upright standing part.
