Toilet with user weight-driven seat lift profile

1. A toilet comprising:

a frame;

a bowl supported by the frame;

a seat also supported by the frame;

a shroud covering the frame;

a lift mechanism supported by the frame for adjusting the position of the seat by raising the seat, lowering the seat, or changing the angle of the seat;

a foot platform positioned to support the feet of a user sitting on the seat wherein the foot platform comprises at least one foot platform weight sensor;

at least one seat weight sensor between the frame and the seat for measuring the weight of a user on the seat; and

a controller receiving data from the at least one foot platform weight sensor and from the at least one seat weight sensor, wherein the controller uses the data from the foot platform weight sensor and from the frame weight sensor to control the at least one lift mechanism;

wherein the lift mechanism comprises:

at least one first actuator pivotally attached to the seat or the frame;

at least one second actuator pivotally attached to the seat or the frame; and

at least one third seat actuator pivotally attached to the at least one second seat actuator and pivotally attached to the frame.

2. The toilet of claim 1 wherein the at least one first seat actuator, at least one second seat actuator, and at least one third seat actuator each operate independent of each other.

3. The toilet of claim 1 wherein the controller calculates the percentage of body weight on the seat and on the foot platform and controls the angle of the seat based on the calculations.

4. The toilet of claim 1 wherein the actuators are configured to be housed within the shroud.

5. The toilet of claim 1 wherein the lift mechanism is adapted to change the angle of the seat.

6. The toilet of claim 1 wherein the at least one weight sensor in the foot platform further comprises weight sensors under the corners of the foot platform.

7. The toilet of claim 6 wherein the at least one weight sensor further comprises one or more weight sensor located under the edges of the foot platform.

8. The toilet of claim 1 wherein the frame further comprises a seat support frame.

9. The toilet of claim 8 wherein the at least one weight sensor in the frame further comprises one or more weight sensors placed between the seat support frame and the seat.

10. The toilet of claim 1 further comprising at least one additional actuator for raising and lowering the foot platform.

11. The toilet of claim 1 further comprising a control system for the user to indicate readiness to change position between seated and standing.

12. The toilet of claim 1 wherein the foot platform further comprises a platform lifting mechanism.

13. The toilet of claim 1 wherein the controller is programmed to the preferences of multiple users.

14. The toilet of claim 1 wherein the shroud comprises a flexible material that adapts as the configuration of the toilet is altered by adjusting the position of the bowl or seat.

15. The toilet of claim 1 further comprising sensors for detecting health and wellness data from the user supported by the frame.

16. The toilet of claim 15 wherein the health assessment devices are selected from the group consisting of imagine cameras, spectrometers, volume measurement devices, weight sensors, temperature gauges, chromatographs, and gas analyzers.

17. The toilet of claim 1 further comprising handles for the user to grasp for support during lifting or lowering.

18. The toilet of claim 17 wherein the handles further comprise sensors for detecting health and wellness data from the user.

19. The toilet of claim 17 wherein the handles further comprise a control system for the user to indicate readiness to change position between seated and standing.

20. The toilet of claim 17 wherein the handles further comprise sensors for detecting the gripping force of the user's hands on the handle.

21. A toilet comprising:

a frame;

a bowl supported by the frame;

a seat also supported by the frame;

a foot platform positioned to support the feet of a user sitting on the seat wherein the foot platform comprises at least one foot platform weight sensor;

at least one seat weight sensor between the frame and the seat for measuring the weight of a user on the seat;

a seat lift mechanism comprising:

at least one first actuator pivotally attached to the seat or the frame,

at least one second actuator pivotally attached to the seat or the frame, and

at least one third seat actuator pivotally attached to the at least one second seat actuator and pivotally attached to the frame; and

a controller receiving data from the at least one foot platform weight sensor and from the at least one seat weight sensor, wherein the controller uses the data from the foot platform weight sensor and from the frame weight sensor to calculate the weight of the user;

wherein the foot platform may be raised above the floor.

22. The toilet of claim 21 further comprising:

handles for the user to grasp during use wherein the handles each comprise at least one handle weight sensor to measure the user's weight on the handles; and

wherein the controller received data from the at least one handle weight sensors that is used to calculate the total weight of the user.
