Abstract: A biosensor obtains at least a first photoplethysmography (PPG) signal at a first wavelength from a user and a second PPG signal obtained at a second wavelength from the user. The biosensor determines a first R value of the user using the first PPG signal and the second PPG signal and compares the first R value of the user to a normal range of R values for a blood type of the user. The biosensor determines a color of blood of the user using the first, second or another PPG signal and determines an abnormal condition that affects red blood cells of the user in response to the color of the blood and/or in response to the comparison or the first R value of the user to a normal range of R values for a blood type of the user.

Abstract: A biosensor identifies a blood type using photoplethysmography (PPG) technology. A PPG circuit obtains a plurality of spectral responses at a plurality of wavelengths detected from skin of a user. A processing circuit determines a blood factor indicator using the plurality of spectral responses. The blood factor indicator may include a signal quality parameter or a ratio R value. A calibration database includes a correlation of the blood factor indicator to a plurality of blood types. The blood type of the user is identified using the blood factor indicator and the calibration database.

Abstract: A biosensor includes an optical circuit that obtains a plurality of photoplethysmography (PPG) signals from light at different wavelengths that is reflected from or transmitted through tissue of a user. A processing circuit determines a measurement value for a nitric oxide (NO) level in blood flow using first and second PPG signals and determines an insulin response from caloric intake using the measurement value for the NO level in blood flow. The first PPG signal is obtained from light at a wavelength having a high absorption coefficient for NO in blood flow and the second PPG signal is obtained from light at a second wavelength having a low absorption coefficient for NO in blood flow. The processing circuit also determines one or more phases of digestion using at least one or more of the plurality of PPG signals.

Abstract: An optical circuit detects PPG signals reflected from skin tissue at one or more different wavelengths. A processing circuit integrated in the biosensor or in communication with the biosensor processes the PPG signals to obtain a level of vasodilation or a period of vasodilation. The processing circuit may determine a circulation level using a phase offset between the PPG signals and/or a correlation value between the PPG signals.

Abstract: An optical circuit detects PPG signals reflected from skin tissue at one or more different wavelengths. A processing circuit integrated in the biosensor or in communication with the biosensor identifies an insulin release event using the a first PPG signal at a first wavelength and second PPG signal at a second wavelength. A correlation function is performed on the first and second PPG signals during the insulin release. The correlation is used to determine a relative change in diameter of vessels during the insulin release event and determine vascular health in response to the relative change.

Abstract: A glucose biosensor includes a plurality of optical fibers configured for placement within the ear canal. A first optical fiber emits light into the ear canal. A plurality of other optical fibers capture and transmit the reflected light back to the glucose biosensor. A plurality of photodetectors are configured in the glucose biosensor to detect the reflected light from the plurality of optical fibers. The glucose biosensor processes the detected light from each photodetector to determine a glucose level measurement. In an embodiment, the glucose biosensor also includes a wireless interface to transmit the glucose level measurements to a glucose meter and/or a gateway.

Abstract: A vehicle includes one or more integrated biosensors, such as finger sensors or other user touchpoints. The integrated biosensors are configured to obtain biosensor data, such as a patient's vitals or concentrations of substances in the blood flow of a user. A control module of a vehicle receives the biosensor data and controls operation of one or more systems of the vehicle in response to the biosensor data. The control module may also present the biosensor data on a display of the vehicle and receive user commands to control the biosensors. The control module may also generate warnings for display in response to the biosensor data exceeding one or more predetermined thresholds.

Abstract: A biosensor includes an optical sensor circuit that emits light directed at skin tissue of a patient at a plurality of wavelengths. A first and second spectral response of light reflected from the tissue is obtained around a first wavelength in a UV range and a second wavelength in an IR range. A measurement of a substance in blood flow is then determined from the spectral responses. A risk of a health condition is obtained using the measurement. The health condition may include one or more of hyperglycemia, diabetes or hypoglycemia.

Abstract: A biosensor includes a PPG circuit that emits light directed at skin tissue at a plurality of wavelengths. A first and second spectral response of light reflected from the tissue is obtained around a first wavelength and a second wavelength. Using absorption coefficients for substances at the plurality of wavelengths, concentration levels of a plurality of substances may then be determined from the spectral responses. The biosensor may thus be used to determine concentrations of a plurality of substances in arterial blood flow using the spectral response.
