The disclosure is generally directed to providing a relaxation regimen to an occupant of a vehicle. In one example method, a processor evaluates a physiological condition of the occupant. The physiological condition can be a heart rate, hear-rate variability, a breathing rate, and/or a blood oxygen level. The processor also identifies an opportune time to offer the relaxation regimen. The relaxation regimen may be offered based on evaluating the physiological condition of the occupant and on identifying the opportune time. Furthermore, the relaxation regimen may be recommended based on the customer preference or usage patterns and the opportune time. The opportune time can be when the vehicle is moving in a cruising mode of operation, is in a stopped or parked state, or is moving in stop-and-go traffic, or location. In another example method, a processor may offer the relaxation regime based on a movement status of the vehicle.

In one embodiment, a system includes, but is not limited to, an aviation head-mounted communication device including at least: a speaker, a physiological sensor configured to obtain physiological data, and a wireless communication interface; and a smartphone, a smartwatch, or tablet device wirelessly linked to the wireless communication interface and configured to receive the physiological data and output the physiological data on a display.

A passenger identification apparatus for vehicles is provided to identify a passenger through integration of a sensor that senses change in permittivity and a sensor that senses change in pressure. The apparatus includes a permittivity change sensing unit that is installed in the seat and senses change in capacitance generated by permittivity of the passenger seated on the seat and a pressure change sensing unit that is installed in the seat and senses change in pressure generated by a load of the passenger seated on the seat. A controller adjusts power supplied to the permittivity change sensing unit and the pressure change sensing unit and determines whether the passenger is seated on the seat and the type of passenger using permittivity and pressure change values sensed by the permittivity change sensing unit and the pressure change sensing unit.

Various embodiments provide systems and methods for identifying impairment using measurement devices.

A system for transportation includes a vehicle occupied by a rider, and an artificial intelligence system for processing a voice of the rider to classify an emotional state of the rider and optimizing at least one operating parameter of the vehicle to improve the emotional state of the rider.

Provided according to embodiments of the invention are photoplethysmography probes designed for use on a user's nasal alar. Methods of using such photoplethysmography probes are also provided herein.

Methods and systems are provided for selectively inhibiting a stop-start controller of a vehicle based on a predicted anxiety of a driver of the vehicle on a road segment that includes one or more road attributes associated with increased levels of anxiety. In one example, selectively inhibiting a stop-start controller of a vehicle based on a predicted anxiety of a driver of the vehicle includes determining a driver classification for a driver operating the vehicle; predicting an anxiety level of the driver at an upcoming traffic condition, based on the driver classification; and selectively inhibiting an upcoming engine idle-stop event based on the predicted anxiety level of the driver.

A remote photoplethysmography (RPPG) system includes an input interface to receive a sequence of measurements of intensities of different regions of a skin of a person indicative of vital signs of the person; a solver to solve an optimization problem to determine frequency coefficients of photoplethysmographic waveforms corresponding to the measured intensities at the different regions, wherein the solver determines the frequency coefficients to reduce a distance between intensities of the skin reconstructed from the frequency coefficients and the corresponding measured intensities of the skin while enforcing joint sparsity on the frequency coefficients; and an estimator to estimate the vital signs of the person from the determined frequency coefficients of photoplethysmographic waveforms.

In order to provide a ship maneuvering support system capable of coping with drowsiness of an operator, a ship maneuvering support system includes: a portable terminal carried by a ship's operator for detecting the operator's drowsiness, and a navigation device used for navigating the ship and performing a predetermined operation when the operator's drowsiness is detected.

A health advisory alert system for a vehicle is presented. A controller may determine whether a vehicle occupant is preparing to exit the vehicle. Upon determination that the vehicle occupant is preparing to exit the vehicle, the controller may determine a location of the vehicle, determine a health advisory metric based on the location of the vehicle, and determine whether personal protective equipment should be worn based on the health advisory metric. Upon determination that personal protective equipment should be worn, the controller may output a notification to the vehicle occupant indicating that personal protective equipment should be worn.
