A system and method of monitoring sobriety using a hand-held breath testing device that, on receipt of a user's breath, generates a breath test signal comprising substance content data and user identification data, and wirelessly transmits the breath test signal to a breath test signal receiving station.

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.

The invention relates to an improvement in a breath alcohol test devices includes within the handheld unit containing a fuel cell, a miniaturized self calibrating test device thereby avoiding the need for 30, 60 and 90 day calibration testing. It also relates to various tamper or circumvention improvements that may be used alone or in combination with the self calibration improvement, including cameras to record a driver providing a breath sample and to verify the location of the driver within a vehicle.

Methods and apparatus allow for passive determination of a driver's Breath Alcohol Concentration (BrAC). Alcohol concentrations can be determined from exhaled breath, however inconvenience to a driver is often a barrier for incorporation of BrAC sensors into vehicles. The methods and apparatus allow for passive determination of a driver's BrAC, while detecting and accounting for a wide range of environmental conditions that may reduce the accuracy of a passive BrAC reading.

A system for communicating the sobriety of a user that includes a testing device that generates a substance content signal comprising a mouthpiece and a user identification device, wherein the substance content signal comprises at least one substance information, wherein the user identification device generates user identification data in response to a user's breath and transmits it from the testing device to a monitoring station, and wherein the testing device further comprises at least one of a LCD screen or a LED; a transceiver unit; a receiving station; and a supervisory monitor.

A new system monitors ethanol alcohol levels of a vehicle operator by collecting sweat from the operator's hands, and detecting the presence, if any, of ethanol in the sweat. The system can then be used, if ethanol is present, to take action, such as immobile vehicle disablement, in the event of intoxication caused by an impermissibly high levels of ethanol of the operator. The system includes devices, referred to as pods in the description, which are sweat-collecting devices that are attached to the steering wheel of the vehicle. If the measurable ethanol in collected moisture from the operator's hands exceeds a preset threshold, the system could be configured to warn the operator to park the vehicle thereafter to disable operation of the vehicle, but if the operator does not so discontinue operation of the vehicle hazard warning lights and audible warnings within and without the vehicle will be activated alerting near vehicles of a dangerous vehicle being operated in close proximity. Likewise the new system monitors for pulse rate and oxygen levels of the operator can be used to recommend operator action when the pulse rate and/or oxygen levels are outside of the normal range for an operator. When the pulse rate and or oxygen levels of the system are outside of the normal parameters for an operator, the system will warn the operator to park the vehicle and thereafter to disable operation of the immobile vehicle, but if the operator does not so discontinue operation of the vehicle the hazard warning lights, on board video, and audible warnings within and without the vehicle will be activated alerting near vehicles of a dangerous vehicle being operated in close proximity, and alarms will be sent to real time recording and monitoring devices.

A system and method of monitoring sobriety using a hand-held breath testing device that, on receipt of a user's breath, generates a breath test signal comprising substance content data and user identification data, and wirelessly transmits the breath test signal to a breath test signal receiving station. The breath test signal includes substance content data and user identification data. The substance content data includes at least one of: a blood alcohol level and a narcotics presence. The user identification data includes compressed image data. The signal receiving station is monitored by a supervisor who is able to intervene should the substance level be greater than a predetermined threshold, or should the user identification data no match with a reference user identification data.

Various aspects of a device and method to manage interaction with one or more control circuits in a vehicle and one or more wearable devices are disclosed herein. The device comprises one or more circuits configured to receive a first set of input values from the one or more wearable devices associated with a first user. The one or more wearable devices are communicatively coupled to the device used in the vehicle. A second set of input values is received from one or more vehicle sensors embedded in the vehicle. An operating mode of the device is determined based on the received first set of input values and the second set of input values. One or more functions of the vehicle are controlled based on the determined operating mode of the device.

A method and a system of deploying an ignition interlock device (IID). The method comprises receiving a time series of breath alcohol content (BrAC) measurements that are unitarily sourced from a pre-identified user, each BrAC measurement of the time series including an alveolar breath component and an interferent breath component; estimating a dissipation rate of alcohol attributable to the pre-identified user in accordance with the time series of BrAC measurements; determining, responsive to estimating the dissipation rate of alcohol, at least a subset of the BrAC measurements as being based on the alveolar breath component but not the interferent breath component; and performing one of triggering and not triggering the IID into a lockout state based on the at least a subset of the BrAC measurements.
