A method and a system of deploying ignition interlock device functionality. The method comprises receiving data in authentication of a user account associated with the IID; rendering a user interface at the mobile computing device, the user interface including indication of a status of the user account associated with the IID; and receiving a selection of a user action responsive to the status of the user account associated with the IID.

A movable carrier auxiliary system includes a driver state detecting device and a warning device. The driver state detecting device includes a physiological state detecting module, a storage module, and an operation module. The physiological state detecting module is adapted to detect a physiological state of a driver. The storage module is disposed in a movable carrier and stores an allowable parameter corresponding to the at least one physiological state. The operation module is disposed in the movable carrier and is electrically connected to the physiological state detecting module and the storage module to detect whether the at least one physiological state of the driver exceeds the allowable parameter or not, and to correspondingly generate a detection signal. The warning device generate a warning message when the detection signal that the at least one physiological state of the driver exceeds the allowable parameter is received.

A system for detecting drunken driver is presented. The system includes an alcohol detecting device, a photographing device, and a locking device. The alcohol detecting device can receive a blood alcohol content value of a driver of a vehicle detected by a sensor, and determine whether the blood alcohol content value exceeds a first predetermined value. The alcohol detecting device can send alcohol concentration exceeding information to the photographing device to record video and to the locking device to lock vehicle when the blood alcohol content value exceeds the first predetermined value.

A system for certifying a detection of a gaseous substance present in air exhaled by an individual. The system includes a sensor providing a measurement of the quantity of the gaseous substance, a portable terminal connected to the sensor and having a camera for taking an image of the individual. The terminal has a module for authenticating the individual and the sensor used for the exhaled air sample by analyzing the data of images using facial recognition and by analyzing a graphic marker for the sensor. The terminal produces an item of data representative of the quantity of gaseous substance measured in the sample and a piece of authenticated identification data of the individual who has exhaled the sample. The system can at the same time authenticate the identity of the individual, authenticate the sensor used, and associate the result of the value of the test with the individual.

In a method and apparatus for measuring an alcohol concentration, a blood alcohol concentration of a driver is rapidly and precisely measured by selecting a plurality of wavelengths based on the absorbance for blood components exerting an influence on the measurement result of the blood alcohol concentration and by measuring the blood alcohol concentration of the driver based on the absorbance detected with respect to a physical body of a user by using the plurality of selected wavelengths. Starting of the vehicle is controlled based on the blood alcohol concentration of the driver, which is measured by measuring the alcohol concentration.

According to one aspect, driver management is provided. One or more speech segments of a driver of an autonomous vehicle may be recorded. A position, a destination, or a previous destination of a driver or an autonomous vehicle may be tracked. An estimated state of the driver may be determined based on one or more of the speech segments, the position, the destination, or the previous destination, and a calendar event associated with the driver or a passenger of the autonomous vehicle. Autonomous driving features may be automatically enabled, disabled, or operation of the autonomous vehicle may be enabled or disabled in different modes based on the estimated state of the driver. Additionally, notifications may be displayed, rideshare applications may be launched, or warnings may be sent based on the estimated state of the driver.

Levels of substance use, location, and vital signs are remotely monitored for a subject. In one embodiment, the system includes a testing device and a communication device. The testing device obtains a breathalyzer sample from a test subject and determines a substance level. The communication device reports the substance level to a remote monitoring station. In addition, location and camera functions of the communication device can report additional information for verification and system integrity. In other embodiments, the system can be incorporated into an ankle bracelet for monitoring movement of an individual or into a vehicle system to prevent operation while impaired.

A system for monitoring the sobriety of a user is provided. The system may include a testing device that generates a substance content signal. The testing device may further include a mouthpiece and a user identification device. The user identification device may generate user identification data in response to a user's breath and may transmit it from the testing device to a monitoring station. The testing device may further include at least one of an LCD screen or a light-emitting diode (LED) light. At least one of the LCD screen or the LED light may display at least one randomly generated visible identification indicia.

Systems and methods are disclosed configured to detect impairment issues, and via an interlock device, inhibit operation of an item of equipment when impairment is detected. The interlock device may comprise a solid state relay, an electromechanical relay, and/or a solenoid. The interlock device may perform power isolation and/or may use a mechanism, such as a rotating cam or gear, to immobilize a control and/or other components. Based on detected impairment, a determination is made as to whether the interlock is to be activated or deactivated.

Multiple enzymes may be present in one or more active areas of an electrochemical analyte sensor for detecting one or more different analytes. In particular, an analyte sensor may comprise a sensor tail configured for insertion into a tissue and one or more working electrodes having a glucose-responsive active area and an ethanol-responsive active area to detect glucose and ethanol in vivo.
