ABSTRACT:
A quilt system having an alarm for indicating when it has slipped off a user is provided. The system includes a quilt having arranged on an inside surface thereof, a plurality of rubber conductors coupled to form two groups of alternating conductors, and a belly-band having a conductive rubber layer disposed on an outside surface thereof. An integrated circuit chip is provided in the quilt and coupled to the rubber conductors thereof for sensing electrical contact between the quilt and the belly-band conductor. A buzzer is coupled to the integrated circuit for indicating a loss of contact between the conductors of the quilt with the belly-band conductor. When the quilt is in contact with the belly-band, the buzzer or oscillator of the integrated circuit chip is kept in its normal inactive state. However, if the quilt moves, and no longer contacts the belly-band, the circuitry of the integrated circuit chip will act as an open-circuit detector, enabling the buzzer to sound, or having a radio emitter circuit transmit a signal to a portable receiver to alert a remotely located person.
