A compact operation sensitive reminder device that is readily attachable to almost any movable item and that emits an alert signal (e.g., audio, visible or tactile) when the item is initially changed from an non-operative condition to an operative condition and then remains silent during the item's operation, and emits the alert signal again only after a certain amount of time that the item has remained non-operative.

[ We claim:] [1.] An apparatus for providing an alert signal each time an item that is operable is changed from a non-operative state to an operative state, said apparatus comprising:a housing;means for releasably coupling said housing to the item;said housing comprising:a transducer for emitting said alert signal;a sensor that generates a signal representative of operation of the item; andcontrol means coupled to said transducer and to said sensor for controlling said transducer emission, said control means activating said transducer for a certain amount of time and then deactivating said transducer each time said control means receives said sensor signal following a predetermined period of time that the item has remained non-operative.
