Abstract of the Disclosure A motion-sensitive alarm system particularly adapted for bicycles and other valuable, movable objects is disclosed. A weighted piezo-electric strip provides the motion indication. An electronic combination and auto arm feature is provided such that the alarm, once armed is triggered upon, movement of the object or upon entering the wrong elect-, ronic combination or entering the combination too slowly. An automatic alarm feature ensures that the alarm is armed once the bicycle has stopped moving for a predetermined period of time.

Why it's free to use
- Filed November 22, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 22, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 22, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
