Definitions

  • -a line-of-sight detector with a predetermined field of view and arranged to measure the coverage by an object of the field of view and to output a signal representing the degree of coverage
  • the breath analysis device is further arranged to store signal relation criteria which comprises a time relation between the line-of-sight detector output signal and the tracer substance signal.
  • the time relation criterion may require that an increase in the recorded line-of-sight detector output signal, indicative of an object approaching the breath analysis device occurs before the onset of the peak in the tracer substance signal.
  • the time relation criterion may further require that a peak in the recorded line-of-sight detector output signal coincide with the peak in the tracer substance signal within a predetermined time period.
  • the steps of monitoring 305 the output signal of the line-of-sight detector 108, and steps 310- 315 to record the line-of-sight signal signature may typically include establishing a background or baseline value. This may be an output signal value sampled over one or a few seconds and averaged. A deviation from the background level, indicating an object being within the field of view of the line-of-sight detector 108 is detected and will initiate the recording of the line-of-sight signal signature. Ways to perform the detection will be further discussed below.
  • the level 20 indicated in Figure 2a is a representation of a typical background signal and the upper level 21 is a representation of the signal resulting from an object being within the field of view.
