Abstract:
1. An impact-induced pulse sensor comprising: a housing having a longitudinal axis; guiding means arranged on said housing; a sensor element adapted to be displaced within said housing along said guiding means when an essentially pulse-shaped impact of a given duration is exerted on said housing, said sensor element being displaced with a predetermined speed (dx/dt) and along a predetermined distance (x), said guiding means being configured such as to affect said speed (dx/dt), said sensor element, further, being made of a magnetic material; pickup means rigidly connected to said housing for magnetically generating a measuring signal (U said sensor element, when displaced, generating in said pickup means a measuring voltage (U M ) depending from said distance (x), said guiding means affecting said speed (dx/dt) such that for impacts with like pulse areas said measuring voltage (U M ) vs said distance (x) is independent from said duration of said pulse-shaped impact.
