The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. The machine can either increase the pressure of a fluid or extract energy from a pressure differential to a rotating shaft. A reference data can be obtained separately or can be obtained from the test data also, wherein the reference data represent the normal operating condition of a system. The soft start circuitry allows for controlled step-wise increase and regulation of the current. The absorbent core further comprises at least one channel and an acquisition-distribution system between the topsheet and the absorbent core, the ADS comprising one, two or more layers wherein the ADS does not comprise a layer comprising at least 50% by weight of synthetic fibers and having a basis weight above 150 gsm. When a collision load is inputted to the front windshield 18, the windshield support 17 is deformed and crushed such that vertically intermediate portions of the front-side member 20 and the rear-side member 21 are deformed so as to go away from each other, thereby minimizing a space which remains uncrushed to enhance the shock absorbing effect.
