The invention relates to devices, systems and methods for thwarting attempts to circumvent breath alcohol level testing and monitoring programs. In-home monitoring systems as well as ignition interlock systems are described. Accelerometers and/or compasses are used to detect movement of the device. GPS and image data are collected at the time samples are collected to verify their authenticity. A system is provided for use by a third party service provider to provide reports and notification to monitoring authorities.

Apparatus, system, and method for implementing and monitoring breath alcohol testing programs, usually from a fixed point location, such as a home

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.

A large scale video display of the present invention is designed to receive a standard NTSC video signal and display it on a large scale array of low cost, voltage or current controlled lamp transducers. The video signals are received by a video capture device which receives and digitizes the video signal. A host processor formats the digital data into a number of 16 bit data words each corresponding to a pixel. A coprocessor receives the 16 bit data words and reformats the data. The reformatted data is connected to a large scale display by a fiber optic connection. The display includes a number of transceivers which receive the formatted video data in a memory buffer. The transceivers also receive a board map from the coprocessor. The map indicates which light boards correspond to each part of the memory where the frame image is stored. This information is used by a number of controllers to determine which lights to turn on and at what level of brightness for any given time.

An improved breath analyzing apparatus for use in an automobile ignition locking system. A breath sample tube receives a breath sample from a user. The breath sample tube is divided into a high pressure section and a low pressure section by an air flow restrictor. A pressure sensor is connected to the high pressure section to determine when a user is blowing into the breath analyzing apparatus. A temperature sensor measures the temperature of the breath sample to insure that it is the same temperature as human breath. A micropump propels a specified volume of the breath sample into a fuel cell which is used to determine the alcohol content. Control means converts the output of the fuel cell into a reading which represents the breath alcohol content of the breath sample. Heating elements warm the fuel cell when the ambient temperature drops below a specified level. The output of the fuel cell is adjusted based on the time it takes the fuel cell to reach its maximum output. A housing holds all the major components of the breath analyzing apparatus and contains a tamper switch therein which detects when the case is opened. A display on the housing shows the alcohol content of the breath sample as well as displaying instructions and messages for the user. The breath analyzer apparatus is used as part of an overall automobile ignition locking system which prohibits starting the car when the operator is intoxicating. The system also requires rolling retests to insure that the driver is still sober.
