Abstract

An apparatus and method for assuring that a machine operator is not under the influence of a chemical, comprising a first sensor positioned proximally to the machine operator and adapted for measuring a vapor concentration proximal thereto, a second sensor positioned distally from the machine operator and adapted for measuring the vapor concentration distally from the operator, a device for comparing the proximal and distal vapor concentrations, and an automated remediating device responsive to the comparing device when the ratio of the first and the second vapor concentrations are within a specified range.

Claims

1. An apparatus for assuring a machine operator is not under the influence of a chemical, the apparatus comprising:

a first sensor positioned proximal to a machine operator and adapted for measuring a first level of a chemical concentration;

a second sensor positioned distal to the machine operator and adapted for measuring a second level of the chemical concentration;

a means for comparing the proximal and distal vapor concentration levels; and

an automated remediation means responsive to the comparing means for enabling a remedial action.

2. The apparatus of claim 1 wherein the first and the second sensors are adapted for measuring a concentration of alcohol vapor in air.

3. The apparatus of claim 2 wherein the alcohol vapor sensors are enabled for an infrared spectroscopy method.

4. The apparatus of claim 1 wherein the first and the second sensors, the comparing means and the remediation means are adapted for mounting within a machine.

5. The apparatus of claim 4 wherein the first of the sensors is positioned on a steering wheel of the machine and the second of the sensors is positioned distally therefrom.

6. The apparatus of claim 5 wherein the steering wheel provides a collection space and a means for admittance of the alcohol vapor into the collection space in proximity to the first of the sensors.

7. The apparatus of claim 5 wherein the first sensor provides a means for sensing alcohol at the skin of the operator.

8. The apparatus of claim 1 wherein the remediating means is enabled for, at least one of:

disabling the machine, visually signaling, audibly signaling and event recording.

9. A method for assuring that a machine operator is not under the influence of a chemical, the method comprising:

positioning a first sensor proximal to a machine operator and adapting the first sensor for measuring a first level of a chemical concentration;

positioning a second sensor distal to the machine operator and adapting the second sensor for measuring a second level of the chemical concentration;

comparing the proximal and distal vapor concentration levels; and

acting remedially in response to the comparing means.

10. The method of claim 9 further comprising the step of adapting the first and the second sensors for measuring a concentration of alcohol vapor in air.

11. The method of claim 10 further comprising the step of enabling the alcohol vapor sensors for an infrared spectroscopy method.

12. The method of claim 9 further comprising the step of the first and the second sensors, the comparing means and the remediation means are adapted for mounting within a machine.

13. The method of claim 12 further comprising the step of positioning the first of the sensors on a steering wheel of the machine and the second of the sensors distally therefrom.

14. The method of claim 13 further comprising the step of providing a collection space and a means for admittance of the alcohol vapor into the collection space in proximity to the first of the sensors.

15. The method of claim 13 further comprising the step of enabling the first sensor for sensing alcohol at the skin of the operator in a contact measurement.

16. The method of claim 9 further comprising the step of at least one of:

disabling the machine, visually signaling, audibly signaling and event recording upon command.
