ABSTRACT:
A compact motion sensitive reminder device that is readily attachable to almost any movable item that emits a visual indication when the item is initially moved from a stationary condition and then remains off during the item's use, and emits the visual indication again only after a certain amount of time that the movable item has remained stationary. Another embodiment of the compact motion sensitive reminder device is integrally formed with an item that is worn by the user, e.g., a roller blade, helmet, etc., and which provides a tactile indication to the person when the item is initially moved from a stationary condition and then remains off during the item's use, and emits the tactile indication again only after a certain amount of time that the movable item has remained stationary.
