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.
Claims28
A biosensor configured for integration in a vehicle, comprising:
- a temperature sensor configured to measure a temperature of an occupant of the vehicle;
- a photoplethysmography (PPG) circuit configured to emit light at a plurality of wavelengths directed at skin tissue of the occupant of the vehicle and obtain a plurality of spectral responses around the plurality of wavelengths of light, wherein a first wavelength has a high absorption coefficient for an indicator of blood alcohol in blood flow and wherein a second wavelength has a low absorption coefficient for the indicator of blood alcohol in blood flow;
- and
- a processing circuit configured to:
- obtain a measurement value for the indicator of blood alcohol in blood flow using the first spectral response and the second spectral response;
- determine a blood alcohol level in blood flow using the measurement value for the indicator of blood alcohol;
- an oxygen saturation level and a heart rate using one or more of the plurality of spectral responses;
- and
- generate a health message for transmission to a vehicle control system including the blood alcohol level, oxygen saturation level, heart rate and temperature.
