Abstract

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.

Claims

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; and

control 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.

2. The apparatus of claim 1 wherein said transducer is a speaker.

3. The apparatus of claim 1 wherein said transducer is a light emitting diode.

4. The apparatus of claim 1 wherein said transducer is a vibrator.

5. The apparatus of claim 1 wherein said control means resides on a single die.

6. The apparatus of claim 1 wherein said alert signal is a visual signal.

7. The apparatus of claim 6 wherein said control means comprises a logic and timing circuit for providing an electrical signal representative of said visual signal to said transducer.

8. The apparatus of claim 7 wherein said logic and timing circuit comprises a timer for terminating said electrical signal representative of said visual signal after said certain amount.

9. The apparatus of claim 1 wherein said alert signal is tactile signal.

10. The apparatus of claim 9 wherein said control means comprises a logic and timing circuit for providing an electrical signal representative of said tactile signal to said transducer.

11. The apparatus of claim 9 wherein said logic and timing circuit comprises a timer for terminating said electrical signal representative of said tactile signal after said certain amount.

12. The apparatus of claim 1 wherein said alert signal is an audible signal.

13. The apparatus of claim 12 wherein said audible signal is a verbal statement.

14. The apparatus of claim 12 wherein said audible signal comprises music.

15. The apparatus of claim 12 wherein said control means comprises an audio circuit for providing an electrical signal representative of said audible signal to said transducer.

16. The apparatus of claim 15 wherein said audio circuit comprises a timer for terminating said electrical signal representative of said audible signal after said certain amount.

17. The apparatus of claim 1 wherein said control means comprises reset means for resetting said control means to prepare to activate said transducer each time the item has remained non-operative for said predetermined period of time or greater.

18. 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 being formed as an integral portion of the item, said housing comprising;

a transducer for emitting said alert signal;

a sensor that generates a signal representative of operation of the item; and

control 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.

19. The apparatus of claim 18 wherein said control means comprises reset means for resetting said control means to prepare to activate said transducer each time the item has remained non-operative for said predetermined period of time or greater.

20. The apparatus of claim 18 wherein said transducer is a light emitting diode.

21. The apparatus of claim 18 wherein said transducer is a vibrator.

22. The apparatus of claim 18 wherein said control means resides on a single die.

23. The apparatus of claim 18 wherein said alert signal is a visual signal.

24. The apparatus of claim 23 wherein said control means comprises a logic and timing circuit for providing an electrical signal representative of said visual signal to said transducer.

25. The apparatus of claim 24 wherein said logic and timing circuit comprises a timer for terminating said electrical signal representative of said visual signal after said certain amount.

26. The apparatus of claim 18 wherein said alert signal is tactile signal.

27. The apparatus of claim 26 wherein said control means comprises a logic and timing circuit for providing an electrical signal representative of said tactile signal to said transducer.

28. The apparatus of claim 27 wherein said logic and timing circuit comprises a timer for terminating said electrical signal representative of said tactile signal after said certain amount.

29. The apparatus of claim 18 wherein said alert signal is an audible signal.

30. The apparatus of claim 29 wherein said audible signal is a verbal statement.

31. The apparatus of claim 29 wherein said audible signal comprises music.

32. The apparatus of claim 29 wherein said transducer is a speaker.

33. The apparatus of claim 29 wherein said control means comprises an audio circuit for providing an electrical signal representative of said audible signal to said transducer.

34. The apparatus of claim 33 wherein said audio circuit comprises a timer for terminating said electrical signal representative of said audible signal after said certain amount.

35. A method for providing an alert signal each time an item that is operable is changed from a non-operative state to an operative state, said method comprising the steps of:

coupling a transducer to the item, said transducer emitting an alert signal when activated by a control means coupled thereto;

detecting the change from the non-operative state to the operative state of the item using a sensor, coupled to the item and to said control means, that generates a signal representative of the changed state of the item; and

activating said transducer by said control means for a certain amount of time and then deactivating said transducer each time the item has changed from a non-operative state to an operative state following a predetermined period of time that the item has remained in the non-operative state.

36. The method of claim 35 wherein said step of activating said transducer includes resetting said control means to prepare to activate said transducer each time the item has remained non-operative for said predetermined period of time or greater.

37. The method of claim 35 wherein said step of said control means activating said transducer includes activating said transducer for said certain amount of time.

38. The method of claim 35 wherein said signal representative of the changed state of the item comprises an alternating signal.

39. The method of claim 35 wherein said alert signal a verbal statement.

40. The method of claim 35 wherein said alert signal comprises music.

41. The method of claim 35 wherein said transducer is a speaker.

42. The method of claim 35 wherein said alert signal is a visual indication.

43. The method of claim 35 wherein said transducer is a light emitting diode.

44. The method of claim 35 wherein said alert signal is a tactile signal.

45. The method of claim 35 wherein said transducer is a vibrator.
