发明名称 Motion-detecting note holder
摘要 A motion-detecting note holder is disclosed. Such a note holder includes a note retention member, a motion sensor, a note-waiting indicator, and a controller in communication with the motion sensor and the note-waiting indicator. The controller, upon receiving a motion-detection signal from the motion sensor, causes the note-waiting indicator to provide a human-perceptible indication that a note is in the note retention member.
