Abstract:
1. A radio frequency breathalyzer system for selectively permitting an individual to operate a vehicle comprising: a. a breathalyzer unit for determining a concentration of alcohol present in a breath sample provided by said individual; b. a radio frequency transmitter unit operatively interconnected with said breathalyzer, said transmitter unit being operative to transmit a first signal corresponding to an alcohol concentration identified by said breathalyzer falling below a threshold level and a second signal corresponding to an alcohol concentration identified by said breathalyzer falling above said threshold level; c. a wearable transceiver device operative to transmit a unique coded signal; d. a vehicle mount immobilizer CPU for selectively controlling access to the operation of said vehicle, said immobilizer CPU having a radio frequency transceiver operative to receive said first and second signals transmitted from said radio frequency transmitter unit, further operative to receive said unique coded signal from said wearable transceiver device, and further operative to transmit periodic warning signals to said wearable transceiver device causing said wearable transceiver device to signal the operator of the vehicle to provide a breath sample into said breathalyzer unit; and e. wherein when said immobilizer CPU receives said second signal, said immobilizer CPU prevents operation of said vehicle.
