A monitored ignition system is provided. A monitored ignition lock unit is contained within a vehicle. The monitored ignition lock unit is in communication with a weight sensor in the driver's seat and a seatbelt detection feature of the vehicle. A monitored ignition lock managing system is contained remotely from the vehicle. The monitored ignition lock and the unit monitored ignition lock managing system are in wireless communication. The monitored ignition lock unit includes a handheld device and a receiving station. The handheld device includes a substance detector, such as a breathalyzer. A camera is aimed to photograph a user when engaged with the substance detector. The handheld device and the receiving station are connected via a tether. The tether is sized such that only a driver sitting relatively close to the monitored ignition lock unit docking can access the substance detector provided in the monitored ignition lock handheld device. If the user exceeds a predetermined reading from the substance detector, the vehicle is stopped from starting. Whether engine starting is allowed or disallowed, a message can be sent to the monitored ignition lock managing system.

There is provided a blood alcohol content (BAC) level actuated lock box. The BAC level actuated lock box includes a housing, a breathalyzer, and a locking device. The housing has a lockable opening for allowing an item to pass there through. The housing is for securing the item therein when the lockable opening is in a locked position. The breathalyzer is for receiving a breath sample and determining a BAC level for the breath sample. The locking device is for maintaining the lockable opening in the locked position when the determined BAC level is greater than a pre-specified BAC threshold and for unlocking the lockable opening when the determined BAC is not greater than the pre-specified BAC threshold.

An ignition interlock and driving monitoring system having multiple sensors connected to a central processor (1) that monitors a vehicle operator for the presence of alcohol in the vehicle operator's system using one or more alcohol sensors (3), such as a transdermal sensor (4) located on a vehicle's steering wheel or a breathalyzer (5). A weight sensor (6) and/or a seat belt sensor (7) monitors the presence of the vehicle operator inside the vehicle to prevent an intoxicated individual from circumventing the system. If at any time the central processor receives a reading from one of the sensors that the vehicle operator is intoxicated or has committed a traffic infraction, then authorities are notified through a wireless notification, such as a message communicated through cellular, satellite, or other wireless technology.

A method and an apparatus is provided for a self-service breathalyzer kiosk system for collecting and reporting blood alcohol level information. The system and method enables a user to submit a report containing the user's current blood alcohol level at the time the report is submitted. In particular, the kiosk may be used to collect the current blood alcohol level information of the user and transmit the report of the current blood alcohol level information of the user over a communication network.

Amounts of volatile organic compositions can be evaluated from vapor samples based on the time dependent response of a fuel cell contacted with the vapor sample at its anode. The time response of the fuel cell signal, e.g., voltage or current, is de-convoluted using a set of standard curves for an equivalent fuel cell configuration obtained separately for each of the volatile organic compositions of a fuel cell with an equivalent construction as the sample-evaluation fuel cell. The methodology can be implemented on a system with an appropriate vapor collection device suitable for the particular application. The method and system can be used to analyze breath samples to evaluate ethanol levels or other volatile organic composition. The system can be a breathalyzer, a vehicle interlock, a medical analysis device or a sensor of environmental or industrial interest.

The calibrating breathalyzer comprises an alcohol sensor, a non-volatile memory, a processing unit or processor, a display and a housing to house these components. The processing unit can calibrate the breathalyzer using the user's body as a simulator based on the user's metabolism rate, type and amount of alcohol consumed by the user. The processing unit determines a sample time to receive a breath sample from the user based on a time to a predetermined calibration point from the drinking start time calculated using the user's metabolism rate and the determined maximum alcohol level. The BAC % measurement based on the user's breath sample at the sample time is used as a reference point in calibrating the breathalyzer.

The portable breathalyzer accessory combines a blood alcohol content measuring tool with a mobile device to measure, store, and send the blood alcohol content of the user. The portable breathalyzer device attaches to a mobile device, wired or wirelessly, to display the blood alcohol content of the user, which is measured through the portable breathalyzer attachment. The blood alcohol content is displayed as a percentage on the mobile device through the corresponding software application. The software application shows the user their blood alcohol content in comparison with the local blood alcohol content limit, which is found by determining the user's location through the GPS technology of the mobile device.

A calibration arrangement for breathalyzers wherein a heightened degree of control and management is applied. Broadly contemplated are arrangements whereby jars or containers of new solution to be used in the calibration arrangement are subject to automatic verification. Also contemplated is the close monitoring of the running of calibration tests and safeguards to ensure that extensively used or old solution is not put into use.

An apparatus includes a protective case for a portable computing device and an integrated alcohol sensor module for measuring the blood alcohol concentration of a user. The apparatus also includes a breath interface, a wireless communication device, an alcohol sensor module and a microcontroller. The protective case houses and protects the portable computing device and the internal electronic components. The breath interface allows the user to provide a breath sample to the alcohol sensor module. The alcohol sensor module measures the alcohol concentration of the breath sample. The microcontroller operates the alcohol sensor module and conveys the alcohol concentration measurements to the portable computing device via the wireless communication device. The microcontroller and the wireless communication device are both mounted within the protective case. The alcohol concentration measurement is used as input for a variety of software application which promote safe drinking and driving habits.

The subject device and associated system relates generally to assessing impairment of an individual to determine whether to provide access to operate a motor vehicle, providing an ignition interlock that works without requiring modification in a motor vehicle and allowing an individual to start the vehicle only following measurement of blood alcohol content or following a series of cognitive tasks to determine the level of impairment. The systems and devices described herein relate incorporate a shielded case designed to disable communication between wireless car keys and the corresponding motor vehicles. This method of achieving an ignition interlock can be combined with a breathalyzer, or with a fingerprint alcohol sensor, or with cognitive tests running on a mobile computing device.

A breathalyzer holder having an opaque body for retaining a breathalyzer having an electrical connection and a blow-tube. The breathalyzer holder includes a body having a lower hole to allow an electrical cable to pass through the body to electrically connect to the breathalyzer. The breathalyzer holder also includes a lid having an aperture that allows a breathalyzer blow tube to pass through to allow a user to blow into the breathalyzer.
