摘要

The object of the present invention is to detect a fire shot event in a weapon. This is achieved by a method comprising the steps of measuring a physical quantity whose magnitude changes in time as a result of a fire shot event so as to obtain a measurement signal, and comparing the measurement signal with a predetermined time-domain fingerprint for said quantity, which fingerprint is characteristic of the way said quantity varies in time upon a fire shot event, in order to confirm the occurrence of a fire shot event in case said measurement signal and said fingerprint match.
