The invention relates to a processing unit, a system, and a computer-implemented method for a vehicle interior, for detecting and reacting to odors of a vehicle occupant.

A system for transdermal alcohol sensing to be worn near a skin surface of a user, including: an alcohol sensor; a microporous membrane; a housing coupled to the alcohol sensor and the membrane, defining a volume between the alcohol sensor and a first membrane side, and fluidly isolating the volume from a second membrane side opposing the first membrane side; an electronics subsystem electrically coupled to the alcohol sensor, operable to power and receive signals from the alcohol sensor; and a fastener operable to position the second membrane side proximal the skin surface.

Among other things, one or more techniques and/or systems are provided for providing users with access to a route for travelling. A user, of a client device, may send a request for access to the route to a route planning service. The route may correspond to a starting location and an ending location. The route planning service may query a route database to identify an entry indicating that a restricted access road segment (e.g., a high occupancy vehicle lane, a shoulder lane, a bus lane, etc.) and/or a road segment (e.g., comprising a traffic light alteration capability) exists between the starting location and the ending location. Responsive to successfully authorizing the user for travelling the restricted access road segment and/or the road segment, the route, comprising the restricted access road segment and/or the road segment, may be provided to the client device.

An apparatus for estimating a concentration of an analyte may include a spectrum acquisition device configured to acquire a first in vivo spectrum of an object, and a processor configured to estimate the concentration of the analyte using the first in vivo spectrum and a concentration estimation model that is generated based on a second in vivo spectrum measured during a timeframe in which the concentration of the analyte in the object is substantially constant, and update the concentration estimation model based on the first in vivo spectrum and the estimated concentration of the analyte.

The present disclosure generally relates to dynamic and adaptive systems and methods for rewarding and/or disincentivizing behaviors.

This invention relates to an ingestible drug delivery device configured for wireless communication with other ingestible drug delivery devices.

An electrochemical fuel cell measures ethanol in human breath and a process maintains such an electrochemical fuel cell. The electrochemical fuel cell includes a first electrode (1), a second electrode (2) and a third electrode (3). The first electrode (1) is used as a measuring electrode in a regular operating mode of the electrochemical fuel cell and as a measuring electrode or as a reference electrode in a maintenance mode of the electrochemical fuel cell. The second electrode (2) is used as a counter electrode in the regular operating mode of the electrochemical fuel cell and as a measuring electrode or as a reference electrode in the maintenance mode of the electrochemical fuel cell. The third electrode (3) is used as a counter electrode in the maintenance mode of the electrochemical fuel cell.

An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service. The opioid overdose monitoring service notifies a first set of contacts when the opioid monitoring information indicates a non-distress stats and notifies a second set of contact when the opioid monitoring information indicates an overdose event. The notification can be a phone call or text message to a specified person, emergency personnel, or first responders, and can include the location of the smart mobile device. The smart mobile device can also include the location of the nearest treatment center having emergency medication used in treating opioid overdose, such as naloxone.

An alcohol level detection device capable of detecting an alcohol level of a driver, includes a thermal camera mounted near a driver seat and to detect a body temperature of the driver, a contact electrocardiogram sensor disposed on a steering wheel steered by the driver and to detect an electrocardiogram waveform and a heart rate of the driver, a non-contact gas detection sensor disposed on a grip of the steering wheel and to detect an alcohol component contained in a gas discharged from a skin of the driver without contact with the skin, and a determination circuit which determine the alcohol level of the driver based on a measurement value of the body temperature detected by the thermal camera, measurement values of the electrocardiogram waveform and the heart rate detected by the contact electrocardiogram sensor, and a value of the alcohol component detected by the gas detection sensor.

A wearable device includes a housing with a window and an electronic module supported by the housing. The electronic module includes a photoplethysmography sensor, a motion sensor, and a signal processor that processes signals from the motion sensor and signals from the photoplethysmography sensor. The signal processor is configured to remove frequency bands from the photoplethysmography sensor signals that are outside of a range of interest using a band-pass filter to produce pre-conditioned signals, and to further process the pre-conditioned signals using the motion sensor signals to reduce motion artifacts from footsteps during subject running. The device includes non-air light transmissive material in optical communication with the photoplethysmography sensor and the window that serves as a light guide for the photoplethysmography sensor. The window optically exposes the photoplethysmography sensor to a body of a subject wearing the device via the non-air light transmissive material.
