Definitions

  • ABSTRACT An anti-evasion system is disclosed for breath alcohol testers including a sound transducer and filter network that distinguishes between the presence and absence of human modulation of the breath sample (such as humming) and prevents a gas sample not obtained in conjunction with such modulation from indicating a 2 Claims, 3 Drawing Figures PATENTEBIAY H974 3809.067
  • the present invention relates to an anti-deception system for breath alcohol testers.
  • An anti-evasion system for use with a breath tester constructed in accordance with the present invention includes a transducer positioned to receive sound waves transmitted at the breath input of the tester and transforms those sound waves into an electrical signal, means (e.g., a filter) coupled to the transducer for distinguishing between the presence and absence of audio frequencies and control means for preventing passing of the test in the absence of pre-selected frequencies.
  • means e.g., a filter
  • FIG. 1 is a perspective view of a breath input unit, of a breath tester incorporating the present invention, with parts brokenaway to show interior parts;
  • FIG. 2 is a block diagram of the inventive system
  • FIG. 3 is a detailed diagram, partly in block form and partly in circuit form, of a part of the system of FIGS. 1 and 2.
  • the filter may substantially attenuate audio frequency signals below 50 hz and above 500 hz and a low hum be required of the user of the breath tester. In this case absence of such a hum would mean that essentially no signal is passed by the filter 22.
  • the signals passed 'by filter 22 are amplified by the amplifier 24 and coupled to a control circuit 26 which serves to prevent a pass output signal from being produced by the tester.
  • the circuit 26 preferably includes an indicator 28, such as a light, which indicates the presence of a proper sound.
  • FIG. 5 A portion of FIG. 5 thereof is depicted in FIG. 3 hereof.
  • the blowing timer 62 and pressure switch 60 are unchanged, but that the base of that switch is, .in accordance with this invention, connected to ground through the circuit 26, specifically through the collector-emitter circuit of an NPN transistor 26A.
  • the collector of transistor 26A is-also connected to one side of the lamp 28 whose other side is connected by a line 260 to the line connecting K4B and K2 (a convenient source of positive potential).
  • the base of transistor 26A is connected through a parallel-connected resistor 26B and capacitor 26C to ground and through a diode 26D to the signal from the amplifier 24.
  • the presence of the proper pressure for a sufficient length of time (e.g., 5 seconds) is used to obtain a sample of deep lung breath from a human user.
  • the present exemplary system adds the requirement that the antievasion output signal from circuit 26 be also present for that period. In the absence of both such signals for the period the test is aborted and no pass signal may be obtained.
  • a breath tester system for administering a test to a human subject to evaluate the alcohol concentration in the subject's breath comprising:
