Abstract
A diaper pail is disclosed. The diaper pail further includes a light source positioned to transmit light directed at one or more sides of an absorbent article at an excitation wavelength of the biological substance. The diaper pail further includes a camera configured to generate one or more images based on detected light emitted from one or more sides of the biological substance. The diaper pail includes a computing device that is configured to calculate measurements of light intensity from an image of a side of the absorbent article, and identify a presence of a threshold amount of biological substance on the side of the absorbent article based on the measurements of light intensity.
Claims20
A diaper pail comprising:
- a light source positioned to transmit light directed at one or more sides of an absorbent article, wherein the light includes a peak wavelength that corresponds to an excitation wavelength of a biological substance such that the light is configured to cause the biological substance to emit light within a range of emission wavelengths;
- a camera configured to detect light emitted from one or more sides of the absorbent article and output one or more images based on the detected light, wherein the light is within the range of emission wavelengths of the biological substance;
- and
- a computing device is configured to execute processor-executable instructions configured to cause the computing device to:
- cause, at a first time, the light source to transmit the light that includes the peak wavelength that corresponds to the excitation wavelength of the biological substance;
- receive, from the camera, an image of a side of the one or more sides of the absorbent article;
- determine, from the image, a first measurement of light intensity at the side of the absorbent article within a first range of emission wavelengths within the range of emission wavelengths;
- determine, from the image, a second measurement of light intensity at the side of the absorbent article within a second range of emission wavelengths within the range of emission wavelengths, wherein the second range of emission wavelengths is different from the first range of emission wavelengths;
- and
- determine that a ratio of the first measurement of light intensity to the second measurement of light intensity is beyond a tolerance;
- and
- identify a presence of a threshold amount of biological substance on the side of the absorbent article.
A method comprising:
- causing, by a computing device at a first time, a light source to transmit light directed at one or more sides of an absorbent article, wherein the light includes a peak wavelength that corresponds to an excitation wavelength of a biological substance such that the light is configured to cause the biological substance to emit light within a range of emission wavelengths;
- receiving, by the computing device from a camera, an image of a side of the one or more sides of the absorbent article, wherein the camera is configured to detect light emitted from the one or more sides of the absorbent article and output one or more images based on the detected light, wherein the light is within the range of emission wavelengths of the biological substance;
- determining, by the computing device from the image, a first measurement of light intensity at the side of the absorbent article within a first range of emission wavelengths within the range of emission wavelengths;
- determining, by the computing device from the image, a second measurement of light intensity at the side of the absorbent article within a second range of emission wavelengths within the range of emission wavelengths, wherein the second range of emission wavelengths is different from the first range of emission wavelengths;
- and
- determining that a ratio of the first measurement of light intensity to the second measurement of light intensity is beyond a tolerance;
- and
- identifying a presence of a threshold amount of biological substance on the side of the absorbent article.
