    • A passenger sensing system of electrodes (12) in varying configurations. Electrodes (12) can be positioned proximate an airbag door (44), each providing a signal corresponding to occupant proximity, and a comparator for comparing the signals employed to make better decisions than with a single signal. Electrodes (12) may be formed on a dielectric substrate (16) and separated by a grounded area (14) configured to block line-of-sight between each of the electrodes (12). Electrodes (12) may be formed of conductive material attached to dielectric material with a conductive coating on one surface. Electrodes (12) may be embedded within a vehicular trimpiece (72) and adjacent to a conductive material connected to ground, and a DC voltage is applied to one electrode to form a conductive path to a second electrode, the conductive path being formed by moisture. A drive electrode (22) and a receive electrode (26) may be formed integrally with a vehicle window (34).

    • A system for detecting impairment of operating ability of transportation vehicle operators due to sleepiness, intoxication or other causes, and for sounding an alarm when operator impairment is found. The invention employs an array of at least three dual electrode capacitive coupling sensors (52), placed in the headliner (1) above the operator's seat, which sense operator head position and motion. Outputs from the sensors (52), after suitable processing and amplification, are analyzed by a microprocessor (32) to determine the operator's head position and motion, through triangulation analysis of distances from the operator's head (16) to each sensor (52). The microprocessor (32) records, tracks and compares the operator head motion data to profiles of normal head motion and impaired head motion, to detect any head motion indicative of operator impairment. When operator impairment is thus determined, the microprocessor (32) activates any of a variety of warning devices (22, 38), to warn and alert the operator and possibly also operators of other nearby vehicles, that there is a state of operator impairment.
    • 检测由于困倦,中毒或其他原因造成的运输车辆操作人员的操作能力的损害的系统,以及在发现操作人员损伤时发出警报的系统。 本发明使用至少三个双电极电容耦合传感器(52)的阵列,放置在驾驶员座椅上方的顶篷(1)中,该传感器感测操作员头部位置和运动。 通过微处理器(32)对来自传感器(52)的适当处理和放大后的输出进行分析,以通过对从操作者头部(16)到每个传感器(52)的距离的三角测量分析来确定操作者的头部位置和运动。 微处理器(32)将操作者头部运动数据记录,跟踪并比较正常头部运动和头部运动受损的轮廓,以检测指示操作者损伤的任何头部运动。 当确定操作人员损伤时,微处理器(32)激活各种警告装置(22,38)中的任何一个,以警告和警告操作者以及可能的其他附近车辆的操作者,存在操作者损伤的状态。
