Abstract
A method for preventing circumvention of a intoxication test includes defining a detection time envelope with a first sensor activated in response to the presence of a human test subject proximate the first sensor and sensing with a second sensor for a change from an ambient condition caused by the presence of the human test subject proximate the second sensor. The intoxication test is validated when a change from the ambient condition is detected by the second sensor during the time envelope defined by the first sensor.
Claims16
A system for testing for intoxication of a human comprising:
- a first subsystem for testing for a substance in the breath of a human;
- a second subsystem for validating the results of an intoxication test performed with the first subsystem, comprising:
- at least one first sensor activated in response to a change in capacitance caused by the presence of an inherent capacitance of the human for generating a first signal defining a time envelope;
- and
- at least one second sensor for generating a second signal in response to a change from an ambient condition caused by the presence of the human, the at least one second sensor comprising an infrared temperature sensor for reflecting an infrared beam off the back of the throat of the human;
- and
- a third subsystem for validating the results of the intoxication test in response to the first and second signals.
A method for preventing circumvention of a intoxication test comprising:
- performing an intoxication test;
- defining a detection time envelope with a capacitive sensor measuring a change in capacitance caused by an inherent capacitance of a human test subject proximate the capacitive sensor;
- sensing with at least one second sensor for a change from an ambient condition caused by the presence of the human test subject proximate the second sensor, the second sensor comprising an infrared temperature sensor for reflecting an infrared beam off the back of the throat of the human test subject;
- and
- validating the intoxication test when a change from the ambient condition is detected by the second sensor during the time envelope defined by the capacitive sensor.
