Abstract: A physiological state screening system may include a temperature sensor, a blood oxygen saturation sensor, a cardiorespiratory sensor unit, a communication circuitry, and one or more controllers. The one or more controllers may include one or more processors communicatively coupled to the temperature sensor and the cardiorespiratory sensor unit. The one or more processors may be configured to execute a set of program instructions maintained in one or more memory units, where the set of program instructions is configured to cause the one or more processors to receive one or more signals, determine one or more physiological states of a subject, determine one or more physiological interventions, and transmit one or more signals instructive of the one or more physiological interventions.

Abstract: A contact-less passenger screening and identification system may include a temperature sensor, a blood oxygen saturation sensor, a cardiorespiratory sensor unit, one or more biometric sensor units, a communication circuitry, and one or more controllers. The one or more controllers may include one or more processors communicatively coupled to the temperature sensor, the cardiorespiratory sensor unit, and the one or more biometric sensor units. The one or more processors may be configured to execute a set of program instructions maintained in one or more memory units, where the set of program instructions is configured to cause the one or more processors to receive one or more signals, determine one or more physiological states of a subject, determine one or more identities of a subject, determine one or more business functions, and transmit one or more signals instructive of the one or more business functions.
