Disclosed herein is a solid-state imaging element including a pixel unit configured to include a plurality of pixels arranged in a matrix and a pixel signal readout unit configured to include an analog-digital conversion unit that carries out analog-digital conversion of a pixel signal read out from the pixel unit. Displacement of the hose from the gripping unit may generate an alarm signal to enable the operator to immediately bring the vehicle to a stop, or it may generate a signal simply to indicate when one of several hoses has been intentionally deployed. The memory module includes a single R memory component to store R data associated with a current codeword, and R data associated with a previous codeword. The cache controller determines not to take the set in which the error was found offline based on determining that the number of currently offline sets in the congruence class is higher than the allowable offline number threshold. Fairing is not linked in rotation to wheel around the first axis, with the result that it is not constrained to rotate around said axis during the advance of the vehicle, whereas said fairing is linked in rotation to said wheel around the second axis, so that it follows the steering movements of said wheel. The inhibitor is believed to catalytically destroy peroxides present, such as hydrogen peroxide, which may be present in trace amounts.
