  • Patent number: 4773863
    Abstract: An amusement device for a toilet bowl or a urinal comprising a urine detector for detecting a urine flow from a human and for providing an electrical signal for activating a sensory stimulus device. A control unit connected to the urine detector converts the electrical signal to a signal for activating the appropriate indicator. In one embodiment of the invention, a plurality of pressure and temperature sensors are imbedded in a plastic base which is disposed in close proximity to the urinal or toilet bowl drain. Disposed alongside each temperature and pressure sensor is an associated LED lamp or buzzer which is activated by that sensor. The device may be connected to a video screen or a speaker disposed above the urinal for providing additional audial and visual stimulation to the user. In another embodiment, a plastic base is disposed entirely within the toilet bowl or urinal in close proximity to the toilet or urinal drain.
