    • The invention relates to a breath test system that is unobtrusive in that it does not require a person subjected to the system to take any other action to breath. It comprises a sensor unit (5) configured to sense the presence or concentration of a volatile substance, present in air flowing through a predefined inlet area (4), and to generate a signal corresponding to the concentration of said substance. There is also provided an apparatus (2, 3) configured to detect the presence of a person at a position in the vicinity of said input area, and having means for registering said presence, and further configured to respond to said presence by delivering an output. This said apparatus includes a unit configured to call for immediate attention of said person, upon said registration of the presence of said person, and a unit configured to provide instructions to said person to direct an expiratory air flow towards said inlet area (4). An analyzer (10) for the determination of breath substance concentration of said person is also provided, the determination being based on said signal corresponding to the substance concentration.
    • 本发明涉及一种不显眼的呼气测试系统,因为它不需要受到系统的人员采取任何其他动作来呼吸。 它包括传感器单元(5),该传感器单元被配置为感测存在于流过预定义入口区域(4)的空气中的挥发性物质的存在或浓度,并且产生与所述物质的浓度相对应的信号。 还提供了一种设备(2,3),其被配置为检测在所述输入区域附近的位置处的人的存在,并且具有用于注册所述存在的装置,并且还被配置为通过将输出 。 该装置包括被配置为在所述人员的存在注册时要求所述人员立即注意的单元,以及被配置为向所述人员提供指令以将呼气气流引向所述入口区域(4)的单元。 还提供用于确定所述人的呼吸物质浓度的分析器(10),所述确定基于对应于所述物质浓度的所述信号。
