Abstract

The novel impedance matching toilet seat apparatus in general, includes a cavity, an acoustic transducer, orifices, and an impedance matching substance dispenser. The cavity is positioned on a top surface of the toilet seat. The acoustic transducer is positioned within the cavity. The orifices are positioned on the top surface adjacent the acoustic transducer. The impedance matching substance dispenser is within an interior portion of the toilet seat. The dispenser includes a reservoir, a conduit, and a pump. The reservoir contains an impedance matching substance and is connected to the conduit and pump. The conduit fluidly connects the reservoir to the orifices.

First claim

The invention claimed is:

1. A toilet seat apparatus comprising:
a cavity positioned on a top surface of the toilet seat;
an acoustic transducer positioned within the cavity;
orifices positioned on the top surface adjacent the acoustic transducer;
an impedance matching substance dispenser within an interior portion of the toilet seat, wherein the dispenser comprises a reservoir containing an impedance matching substance, the reservoir connected to a conduit and a pump; and
wherein the conduit fluidly connects the reservoir to the orifices.

2. The toilet seat apparatus of claim 1 , comprising multiple cavities positioned on the top surface of the toilet seat with multiple acoustic transducers positioned within the cavities.

3. The toilet seat apparatus of claim 1 , wherein the pump comprises one or more valves.

4. The toilet seat apparatus of claim 1 , wherein the reservoir comprises one or more valves.

5. The toilet seat apparatus of claim 4 , wherein one of the one or more valves is an impedance matching substance refilling port.

6. The toilet seat apparatus of claim 1 , wherein the conduit comprises a valve.

7. The toilet seat apparatus of claim 1 , wherein the dispenser further comprises a heater.

8. The toilet seat apparatus of claim 7 , further comprising a temperature sensor.

9. The toilet seat apparatus of claim 7 , wherein the dispenser comprises a heat exchanger.

10. The toilet seat apparatus of claim 9 , wherein the heat exchanger is thermally coupled to the conduit.

11. The toilet seat apparatus of claim 9 , wherein the heat exchanger is thermally coupled to the reservoir.

12. Toilet seat apparatus of claim 9 , wherein sections of the conduit pass through the heat exchanger.

13. The toilet seat apparatus of claim 7 , wherein the heater is a resistance heater adjacent the conduit.

14. The toilet seat apparatus of claim 7 , wherein the heater is an inductive heater comprising a ferromagnetic core positioned within the conduit.

15. The toilet seat apparatus of claim 9 , wherein the heater is a direct current resistive heater and the heat exchanger is thermally coupled to the heater.

16. The toilet seat apparatus of claim 1 , further comprising a resistive heater embedded in the toilet seat.

17. Toilet seat apparatus of claim 1 , further comprising a controller electrically coupled to the acoustic transducer and the pump.

18. Toilet seat apparatus of claim 17 , further comprising motion sensors electrically coupled to the controller and positioned on the top surface of the toilet seat.

19. Toilet seat apparatus of claim 17 , further comprising a light transceiver which is electrically coupled to the controller and positioned on the top surface of the toilet seat.

20. Toilet seat apparatus of claim 17 , further comprising a wireless transceiver electrically coupled to the controller.
