  • Toilet Seat and Cover Position Detection System
    Publication number: 20100058520
    Abstract: A toilet seat and cover position detection system that includes a toilet assembly in a room with a door wherein a two position toilet seat cover is attached to the toilet assembly. Attached to the seat cover is a transmitter device means whereby the transmitter device is activated to broadcast a signal when the seat cover is in the vertical position. A receiver device means attached to the door and activated upon opening the door, detects the transmitter broadcast signal emitted when the seat cover is in the raised position. When a signal is detected, an alarm device means is activated by the receiver device and notifies user that the seat cover is in the raised position as the user opens the door to exit. The transmitter device means may also be attached to a two position toilet seat.
