Abstract: An alcohol detection system incorporates a resistive touch sensor mountable in a vehicle for determining presence of alcohol based on changed skin resistance. An ignition interlock is provided in the vehicle and a microcontroller is connected to and receives data from the touch sensor and provides a signal to open the interlock to disable the vehicle upon receipt of data from the touch sensor exceeding a predetermined value. The system also employs operator identification and vehicle location systems with a data logger allowing the microcontroller to store data on test results, operator identification and vehicle location. Additionally, the system may employ a cellular communication system to allow reporting of the data to a remote location.

Abstract: A steering wheel has a structural skeleton forming a core within an outer covering, the covering and skeleton forming a hub portion having at least one arm interconnecting the hub portion with an outer wheel portion. The skeleton within the outer wheel portion has a U-shaped cross sectional conformation. A wire harness is positioned within the U-shaped conformation of the outer wheel portion and a plurality of ethanol detectors are mounted in spaced apart relationship within the outer wheel portion and adjacent to an outer surface of the steering wheel. The ethanol detectors communicate with the wire harness and an electrical circuit, the circuit engaging the hub portion of the skeleton. The circuit is in communication with the wire harness for receiving electrical signals from the ethanol detectors for sensing ethanol vapors in proximity to at least one of the ethanol detectors.
