Abstract: Provided is a heat generating arrangement and a method for generation of heat to be used in a heat consumer. The heat generating arrangement uses combustion of aluminium and hydrogen to raise the temperature of superheated steam inside the heat generating arrangement. The heat in the superheated steam can thereafter be used in a heat consumer, such as a heat exchanger.

Abstract: A piezoelectric sensor arrangement for use in a projectile comprises a piezoelectric sensor enveloped by a damping layer adapted to attenuate signals of frequencies above a predetermined cutoff frequency whereby the voltage output signal of the piezoelectric sensor upon impact on a desired hard target can be discriminated from voltage output signals originating from impact on undesired soft objects. A method of discriminating voltage outlet signals by means of the piezoelectric sensor arrangement and the use of a piezoelectric sensor arrangement in a projectile to safeguard unintentional detonation does not occur is described herein.
