Abstract

The bidet system may include multiple seat scales which may float between the toilet bowl rim and the toilet seat. These seat scales may collect measurements which are transmitted to a controller. The controller may include instructions to calculate a user's center of mass based on the measurements and to identify the position of the user's anus based on the center of mass. The controller may then transmit instructions to a bidet wand directing direct the bidet wand to a position which aims a cleansing fluid spray toward the user's anus. A camera which collects images of the user's anal and urogenital region may also be included in the bidet system. The camera may transmit obfuscated images to the controller to identify other areas of the user's anatomy in need of cleansing. The controller may direct the bidet wand to aim a cleansing fluid spray toward these areas.

First claim

We claim:

1. A bidet wand positioning system comprising:
a toilet seat;
a plurality of seat scales in mechanical connection with an under side of the toilet seat, wherein the plurality of seat scales comprises three balances;
a bidet wand comprising a nozzle, wherein the bidet wand emits a cleansing fluid spray from the nozzle;
a bidet system controller comprising a non-transitory computer-readable medium, wherein the bidet system controller receives measurements of mass from each of the plurality of seat scales, wherein the non-transitory computer-readable medium comprises instructions for calculating a center of mass of a user seated on the toilet seat using the measurements of mass, wherein the non-transitory computer readable medium comprises instructions for estimating a location of the user's anus based on the calculated center of mass, wherein the system controller sends an electronic signal to the bidet wand directing the bidet wand to emit a cleansing fluid spray toward the calculated location of the user's anus.

2. The bidet wand positioning system of claim 1 , wherein the three seat scales are in connection with a front center, a rear left, and a rear right side of the underside of the toilet seat.

3. A bidet wand positioning system comprising:
a toilet seat;
a plurality of seat scales in mechanical connection with an under side of the toilet seat;
a bidet wand comprising a nozzle, wherein the bidet wand emits a cleansing fluid spray from the nozzle;
a bidet system controller comprising a non-transitory computer-readable medium, wherein the bidet system controller receives measurements of mass from each of the plurality of seat scales, wherein the non-transitory computer-readable medium comprises instructions for calculating a center of mass of a user seated on the toilet seat using the measurements of mass, wherein the non-transitory computer readable medium comprises instructions for estimating a location of the user's anus based on the calculated center of mass, wherein the system controller sends an electronic signal to the bidet wand directing the bidet wand to emit a cleansing fluid spray toward the calculated location of the user's anus; and
a hinge, wherein the hinge is in mechanical connection with the toilet seat, and wherein the non-transitory computer-readable medium in the system controller subtracts the mass of the hinge from the mass measurements collected by the plurality of seat scales.

4. A bidet wand positioning system comprising:
a toilet seat;
a plurality of seat scales in mechanical connection with an under side of the toilet seat, wherein the toilet seat floats on the plurality of seat scales;
a bidet wand comprising a nozzle, wherein the bidet wand emits a cleansing fluid spray from the nozzle;
a bidet system controller comprising a non-transitory computer-readable medium, wherein the bidet system controller receives measurements of mass from each of the plurality of seat scales, wherein the non-transitory computer-readable medium comprises instructions for calculating a center of mass of a user seated on the toilet seat using the measurements of mass, wherein the non-transitory computer readable medium comprises instructions for estimating a location of the user's anus based on the calculated center of mass, wherein the system controller sends an electronic signal to the bidet wand directing the bidet wand to emit a cleansing fluid spray toward the calculated location of the user's anus.
