In order that safety systems, such as distress beacon emitters carried on board an aircraft can be triggered both in the case of a very short violent shock or impact and during a longer but less violent shock or impact, a shock or impact detector is proposed which takes into account both the amplitude and the dutation of a possible shock or impact. This detector comprises an electromagnetic transducer (50) whose coil supplies a pulse signal having an amplitude and duration proportional to the amplitude and to the duration of the shock.

Why it's free to use
- Filed September 7, 1993 and granted April 22, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 7, 2013.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
