Abstract

A thin scale apparatus for measuring body weight includes 5 or more force sensors within a total thickness of between 0.4 inches and 0.004 inches measured between a bottom surface and a top surface of the thin scale apparatus. The thin scale is designed to be thin enough to be non-intrusive or not recognized by a user. A weight of a toilet user may be determined as a combination of additive force of force sensors in a thin scale and force sensor associated with a toilet seat of a toilet. The force sensors may be positioned in one or more cavities on a bottom side of a substrate material of the thin scale or be embedded within a substrate material. Embodiments of a standalone thin scale and a thin scale with a toilet are disclosed.

First claim

The invention claimed is:

1. A thin scale apparatus comprising:
fifty or more force sensors connected to a substrate;
a highest surface of a top of the thin scale apparatus forming a first plane substantially parallel to a second plane formed by a lowest surface of the thin scale apparatus;
wherein the first plane and the second plane are separated by a total distance of between 0.4 inches and 0.004 inches and an entirety of the fifty or more force sensors and the substrate are located between the first plane and the second plane; and
wherein the highest surface is a top surface of a bio-impedance electrode connected to the top of the thin scale apparatus.

2. The thin scale apparatus of claim 1 , further comprising a processor, memory, or a wireless transceiver between the first plane and the second plane.

3. The thin scale apparatus of claim 2 , wherein the wireless transceiver communicates weight and bio-impedance information with a remote device.

4. The thin scale apparatus of claim 1 , wherein the thin scale apparatus further comprises a visual display between the first plane and second planes.

5. The thin scale apparatus of claim 4 , wherein the visual display is photo-chromatic.

6. The thin scale apparatus of claim 1 , wherein the bio-impedance electrode is also a haptic or visual marker for positioning a user's foot.

7. The thin scale apparatus of claim 1 , further comprising an electrical communication with a toilet.

8. The thin scale apparatus of claim 7 , wherein the toilet comprises an induction coil coupled to the power source, wherein the induction coil of the toilet is electromagnetically coupled to a coil in the thin scale apparatus.

9. The thin scale apparatus of claim 7 , wherein the thin scale apparatus comprises extensions that wrap around a base of the toilet.

10. The thin scale apparatus of claim 7 , wherein the thin scale apparatus comprises wires or contacts for electrically connecting to the toilet.

11. The thin scale apparatus of claim 7 , wherein one or more magnets hold and position the thin scale apparatus against the toilet.

12. The thin scale apparatus of claim 11 , wherein the toilet or the thin scale apparatus comprises one or more metallic contacts positioned at an outer surface to magnetically couple with the one or more magnets.

13. The thin scale apparatus of claim 7 , wherein the toilet comprises a wireless transceiver which communicates with a wireless transceiver of the thin scale apparatus.

14. The thin scale apparatus of claim 7 , wherein the thin scale apparatus and toilet are coupled electrically by means of a metallic contact in order to charge or power the thin scale apparatus.

15. The thin scale apparatus of claim 7 , wherein the toilet comprises force sensors.

16. The thin scale apparatus of claim 1 , wherein the bio-impedance electrode is one of thin sheets, patches, or strips of conductive metal, conductive spray paint, or electrically conductive silicon.

17. The thin scale apparatus of claim 1 , wherein the thin scale apparatus comprises a heating coil located between the first plane and the second plane.

18. The thin scale apparatus of claim 1 , wherein the thin scale apparatus comprises a temperature sensor located between the first plane and second plane.
