摘要： A sensor system is provided. The sensor system includes an electrically conductive surface and an air coil in proximity to the electrically conductive surface. The air coil has a wire winding pattern with an “L” shaped cross section. The sensor system also includes a controller, coupled to the air coil and configured to sense a change in impedance of the air coil due to movement of the electrically conductive surface. A safety device is coupled to the controller. The controller activates the safety device if the change in impedance of the air coil exceeds a predetermined threshold.

摘要： A sensor system includes an electrically conductive surface and an air coil in proximity to the electrically conductive surface. The air coil includes a first coil and a second coil. The first coil forms a wire winding pattern having a cross section perpendicular with the cross section of a wire winding pattern of the second coil. The sensor system also includes a controller electrically coupled to the air coil and configured to sense a change in impedance of the air coil due to relative movement between the air coil and the electrically conductive surface. The sensor system also includes a safety device electrically coupled to the controller.

摘要： The severity of a crash is discriminated from a measure of relative motion of first and second elements of a vehicle, wherein an initial time is recorded when a variable point in the associated phase space of relative velocity and relative displacement crosses a first threshold boundary, and a safety restraint actuator is actuated if a subsequent time when the variable point crosses a second threshold boundary is within threshold period following the initial time. In accordance with another aspect, a type of impacting object is discriminated from a first measure of relative motion at a first location, and a crash severity is discriminated from a second measure of relative motion at a second location, wherein the relative motion at the first location is unipolar for one type of crash and bipolar for another, and the relative motion at the second location is unipolar for both types of crashes. The second threshold boundary can be responsive to discrimination of the type of impacting object by the first relative motion sensor.
摘要翻译：碰撞的严重性与车辆的第一和第二元件的相对运动的量度相区分，其中当相对速度和相对位移的相关相位空间中的可变点跨越第一阈值边界时，记录初始时间，以及如果可变点越过第二阈值边界的后续时间在初始时间之后的阈值周期内，则启动安全限制致动器。根据另一方面，一种冲击物体与第一位置处的相对运动的第一测量值进行区分，并且在第二位置处将碰撞严重程度与第二相对运动测量值进行区分，其中第一位置处的相对运动位置对于一种类型的碰撞是单极的，并且对于另一种类型是双极的，并且对于两种类型的故障，第二位置处的相对运动是单极的。第二阈值边界可以响应于第一相对运动传感器对冲击物体的类型的区分。
