    • An occupant sensor (10) comprises an electric field sensor (100) comprising a plurality of first electrodes (103) mountable within a vehicle seat (3), wherein the plurality of first electrodes (103) are disposed on a common surface and are non-overlapping with one another. The electric field sensor (100) further comprises at least one second electrode (116), wherein the first (103) and second (116) electrodes are proximate to one another. A sensing circuit (106) is operatively coupled to the first (103) and second (116) electrodes so as to control the level of capacitance between an occupant (5) on the vehicle seat (3) and a circuit ground (110). In a second aspect, the electric field sensor incorporates a lattice electrode (119) with a ground plane (120). In a third aspect, the electric field sensor incorporates a receive electrode (126) that receives a signal from a sensing electrode (128) for purposes of mitigating the effects of a seat wetting condition.
    • 乘员传感器(10)包括电场传感器(100),该电场传感器包括可安装在车辆座椅(3)内的多个第一电极(103),其中多个第一电极(103)设置在共同表面上并且不是 与另一个重叠。 电场传感器(100)还包括至少一个第二电极(116),其中第一电极(103)和第二电极(116)彼此靠近。 感测电路(106)可操作地耦合到第一电极(103)和第二电极(116),以便控制车辆座椅(3)上的乘客(5)和电路接地(110)之间的电容水平。 在第二方面,电场传感器包括具有接地面(120)的晶格电极(119)。 在第三方面中,电场传感器包括接收来自感测电极(128)的信号的接收电极(126),以减轻座椅润湿状况的影响。
