DETAILED DESCRIPTION
It will be readily understood that the components of the present invention, as generally described and illustrated in the Figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the invention, as represented in the Figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of certain examples of presently contemplated embodiments in accordance with the invention. The presently described embodiments will be best understood by reference to the drawings.
FIG. 1 shows a cross-sectional view of a user 102 sitting on a toilet. Noise 110 which radiates from an inside bowl area 108 are received by one or more microphones 106 and 114. Microphones 106 and 114 may be a single microphone or may comprise an array of microphones (as shown in FIG. 4) pointed in different directions. Circuitry connected to microphones 106 and 114 may transmit or record sound waves 110. The speakers 116, 118, 104 and 120 may each comprise an array of speakers (as shown in FIG. 4) pointed in different directions. The speakers may provide user feedback based on recorded noises 110. Additional microphones may be located on a toilet lid 124, on toilet tank 126, or at a remote location such as a bathroom door. Additional speakers may also be located on lid 124, on toilet tank 126, or at a remote location such as a bathroom door. Microphones 106 and 114 may be located on or in a toilet seat as shown in FIG. 1. Microphones 106 and 114 may receive in multiple directions including from the bowl and toward a user or a lid of the toilet. Lid 124, the toilet seat, or an inside of the toilet may be made of sound absorptive material such as mass loaded vinyl, high density material, anechoic material, or geometric sound canceling formations. Toilet sound 110 is radiated from a bowl area 108 and received by microphone 114. Microphone 114 provides toilet sound wave signals to circuitry (not shown). The circuitry may transmit or store the toilet sound wave signals. One or more speakers may provide user feedback. User feedback may include a volume or amount of urination, frequency of urination within a given time frame, frequency of bowel movements within a given time frame, constipation information (based on bowel movement plopping noises and size of bowel movement noise information), etc. User feedback may be determined from predetermined/prerecorded sound patterns compared to toilet noises picked up by toilet microphones while a user is using a toilet. For instance, a toilet user may be constipated and the user may make sounds that match prerecorded noises of toilet users who are constipated, such as groaning or grunting noises picked up toilet microphones. In another example, a urination noise length and urination noise harmonics may match a predetermined condition of urinary retention or dehydration or bladder infection. User feedback may be based on a match of a prerecord noise pattern of toilet noise medical conditions.
FIGS. 2a and 2b show a bottom side 202 of a toilet seat and a top side of a toilet seat 212. Shown at 204 and 206 are combination microphone speaker arrays which may be used to receive sound waves and transmit user feedback. One or more speakers may provide user feedback. User feedback may include a volume or amount of urination, frequency of urination within a given time frame, frequency of bowel movements within a given time frame, constipation information (based on bowel movement plopping noises and size of bowel movement noise information), etc.
Referring now to FIG. 3, combination microphone speaker arrays 302, 304, 306 and 308 may be used to transmit sound waves and receive sound waves. One or more speakers may provide user feedback. User feedback may include a volume or amount of urination, frequency of urination within a given time frame, frequency of bowel movements within a given time frame, constipation information (based on bowel movement plopping noises and size of bowel movement noise information), etc. The circuitry may be powered by a battery, by a power supply with the toilet, or by a non-contact inductive power source within the toilet seat and another fixed part or the toilet such as the toilet tank, or toilet bowl. The speakers and microphones may be placed adjacent to each other in arrays or be separate arrays which may be spherical or hemispherical arrays of speakers and/or microphones. The microphones and/or speakers 302, 304 may be positioned on a lid 306 of a toilet seat 312 as shown in FIG. 3 and provide feedback to one or more circuits associated with microphone and/or speakers.
FIG. 4 shows sound waves 402 entering microphone 404. Microphone array 404 provides a sound wave input signal to circuit 410 by way of each microphone 414 of the array 404. Circuit 410 may contain active and passive circuitry which stores or records the sound wave signal. Circuit 410 may also output a user feedback signal to one or more speakers 416 of speaker array 406. Speaker array 406 may provide a toilet user with feedback 408 related to toilet noises 402 received. Circuit 410 may be connected to a computer or remote database 412. Computer 412 may include a battery or power supply for powering circuitry 410.
Referring now to FIG. 5, one or more microphones within the arrays 504, 506, 508, 510, 512 and 514 may provide directional information about a propagation path of a sound wave. The microphones may receive different amplitude signals resulting from reception of sound waves. The different amplitude signals may be used to determine a propagation direction of the sound waves. Circuitry 518 may receive one or more microphone input signals with sound wave frequency and direction information. The circuitry may then locally store or transmit the sound wave signals to a remote database for processing. The circuitry may include a processor and be powered by a power source 516. The power source may be a battery, a power supply within the toilet, or a non-contact inductive power source within multiple parts of the toilet such as the toilet seat and another location of the toilet. A communication section 520 may wirelessly transmit information gathered by the microphones to a remote computer or user device. The information transmitted may include noises from within the toilet including bowel movements, bowel movement frequency, urination duration, urination frequency, user speech, user commands, flatulence, etc. The information may be used to provide medical data to doctors, tracking of digestive health, tracking of urinary system health, voice recognition commands, talking on a telephone while in a restroom. Sounds picked up by the microphones may be used to cancel sounds such as urination sounds and amplify wanted sounds such as a user's voice talking to a friend over the Internet through microphones in the toilet. The canceled sounds may be canceled by mixing sound waves in free space or by canceling or filtering out unwanted sound signals in electronic communications. The speakers and microphones may be placed adjacent to each other in arrays or be separate arrays which may be spherical or hemispherical arrays of speakers and/or microphones. The microphones and/or speakers 504, 506, 508, 510, 512 and 514 may be positioned on a toilet seat 502 and provide feedback to one or more circuits associated with microphone and/or speakers. The speakers may be used to transmit desired sounds in addition to inverted unwanted sound waves. For instance, if a user is talking to a friend over the Internet using the microphones and the speakers on the toilet, the microphones and speakers may also be providing noise canceling features while the user is using the toilet. A user may pair the noise canceling toilet to a user device and talk on the telephone hands free without worrying about toilet noises being transmitted through to the other end of the telephone call.
In FIG. 6, combination microphone speaker arrays 604, 606, 608, 610, 612 and 614 may be used to transmit inverted sound waves and receive unwanted sound waves. The speakers may transmit inverted sound waves in an upward direction toward a sound point origin location or reflection location outside of the toilet bowl or to a virtual space. The transmitted inverted sound waves may be transmitted in a propagation direction similar to a reflected unwanted sound reflection path or along a similar propagation directional axis. One or more microphones within the arrays 604, 606, 608, 610, 612 and 614 may provide directional information about a propagation path of an unwanted sound wave. The microphones may receive different amplitude signals resulting from reception of unwanted sound waves. The different amplitude signals may be used to determine a propagation direction of the unwanted sound waves. Circuitry 518, of FIG. 5, may receive one or more microphone input signals with unwanted sound wave frequency and direction information. The circuitry may then invert the received signal and transmit the inverted unwanted sound wave signal to one or more speakers in an array of speakers within 604, 606, 608, 610, 612 and/or 614. The circuitry may be powered by a power source 516 of FIG. 5. The power source may be a battery, a power supply within the toilet, or a non-contact inductive power source within multiple parts of the toilet such as the toilet seat and another location of the toilet. A communication section 520, of FIG. 5, may wirelessly transmit information gathered by the microphones to a remote computer or user device. The information transmitted may include noises from within the toilet including bowel movements, bowel movement frequency, urination duration, urination frequency, user speech, user commands, flatulence, etc. The information may be used to provide medical data to doctors, tracking of digestive health, tracking of urinary system health, voice recognition commands, talking on a telephone while in a restroom. Sounds picked up by the microphones may be used to cancel unwanted sounds such as urination sounds and amplify wanted sounds such as a user's voice talking to a friend over the Internet through microphones in the toilet. The canceled sounds may be canceled by mixing sound waves in free space or by canceling or filtering out unwanted sound signals in electronic communications. The speakers and microphones may be placed adjacent to each other in arrays or be separate arrays which may be spherical or hemispherical arrays of speakers and/or microphones. The microphones and/or speakers 604, 606, 608, 610, 612 and 614 may be positioned on a toilet seat 602 and provide feedback to one or more circuits associated with microphone and/or speakers. The speakers may be used to transmit desired sounds in addition to inverted unwanted sound waves. For instance, if a user is talking to a friend over the Internet using the microphones and the speakers on the toilet, the microphones and speakers may also be providing noise canceling features while the user is using the toilet. A user may pair the noise canceling toilet to a user device and talk on the telephone hands free without worrying about toilet noises being transmitted through to the other end of the telephone call.
In FIG. 7, a cross-sectional view of a user 702 sitting on a toilet. noise or unwanted sound waves 708 which radiate from inside of a bowl area of a toilet 726 are received by one or more microphones 706, 716, 714, 704, 718, and 720. Microphones 706, 716, 714, 704, 718, and 720 may each be a single microphone or may each be an array of microphones pointed in different directions. Circuitry connected to microphones 706, 716, 714, 704, 718, and 720 invert the unwanted noise or unwanted sound waves 708 and output an inverted unwanted sound wave signal to one or more speakers 706, 716, 714, 704, 718, and 720 which transmit the inverted unwanted noise or inverted unwanted sound waves 710. The speakers 706, 716, 714, 704, 718, and 720 may each comprise an array of speakers pointed in different directions. The inverted unwanted sound waves 710 mix or combine with unwanted sound waves to cancel or substantially cancel each other. The speakers may transmit the inverted signal in a similar direction compared to a propagation direction of received unwanted sound waves. The speakers may transmit the inverted signal in a downward direction into the toilet bowl, in an upward direction out of the toilet bowl, or in a combination of directions based on a direction of the unwanted sound radiation. Additional microphones may be located on a toilet lid 724, on toilet tank 726, or at a remote location such as a bathroom door. The additional microphones may provide feedback about noise cancelation in order to calibrate the output of one or more speakers. Additional speakers may also be located on lid 724, on toilet tank 726, or at a remote location such as a bathroom door and may provide additional noise cancelation radiation. Microphones 706, 716, 714, 704, 718, and 720 may be located on or in a toilet seat as shown in FIG. 7. Microphones 706, 716, 714, 704, 718, and 720 may transmit in multiple directions including into the bowl and toward a user or a lid of the toilet. Lid 724, the toilet seat, or an inside of the toilet may be made of sound absorptive material such as mass loaded vinyl, high density material, anechoic material, or geometric sound canceling formations. sound 708 is radiated from a bowl area of a toilet and received by microphone array 716. Microphone array 716 provides an unwanted sound wave signal to circuitry (not shown). The circuitry inverts the unwanted sound wave signal and outputs the inverted unwanted sound wave signal to one or more speakers 714. The speakers may be chosen based on a direction of propagation of the unwanted sound. The direction of propagation may be determined based on an array of microphones which may be located at microphone 716. The array may be formed in a hemispherical or spherical shape and the direction of propagation may be determined based on an intensity received at one or more microphones in the array. Speaker 714 may also comprise an array of speakers forming a hemispherical or spherical shape and one or more of the speakers 714 may be used to transmit the inverted unwanted sound wave signal 714 is a similar direction compared to the propagation direction of the unwanted sound wave 708. If microphone array 716 receives multiple unwanted sound waves which have different propagation directions, then multiple inverted signals may be created and sent to multiple speakers within an array of speakers and the inverted signals may be transmitted by one or more speaker arrays in different propagation directions.
