Open fastener detection & warning device |
(57) The invention comprises five components: a fastener, which is affixed or part on
an article of clothing or some other object; a detection system, which detects whether
the fastener has been left undone; a warning system, which warns the user that the
fastener is undone; a timer circuit, which is activated when the detectors signal
that the fastener has been left undone and thus controls the onset of the warning
system; and the power source, that provides for the functioning of the detection system,
the warning system and the timer circuit. This invention has the characteristic of
warning the user that a fastener has been left undone and thus may prevent the occurrence
of embarrassment, injury, loss or damage.
