    • An electric jack load balancing method and device for reducing the difference in load carried by each jack of a pair of electric jacks while adjusting the attitude of a platform. The device includes a controller configured to reduce the difference in load carried by each jack of a pair of electric jacks. The method includes monitoring the power draws of the jack motors of the pair of electric jacks, comparing the ratio of the power draws of the jack motors to a predetermined desirable power draw ratio, and when the jack motor power draw ratio differs from the desirable power draw ratio, modifying the operation of the jacks in such a way as to decrease the difference between their actual power draw ratio and the predetermined desirable power draw ratio.
    • 一种电动千斤顶负载平衡方法和装置,用于在调整平台姿态的同时减小一对电动千斤顶的每个千斤顶承受的负载差异。 该装置包括控制器,该控制器被配置为减少由一对电插座的每个插座承载的负载差异。 该方法包括监测一对电气插座的千斤顶电机的功率消耗,将千斤顶电机的功率比与预定的期望功率拉伸比进行比较,以及当千斤顶电机功率拉伸比与期望功率不同时 拉伸比,以减小它们的实际功率拉伸比和预定的期望功率拉伸比之间的差异的方式修改插孔的操作。

    • An autocalibration method for use within an electronic compass in a vehicle is disclosed. The method includes steps of initializing variables and then retrieving sensor readings from at least two axis. The method then compares the compass tilt to a predetermined threshold. Next the method will determine if the sensor reading is a minimum or maximum for the current calibration cycle. Next the method will determine if the maximum value of the sensor readings is greater than the predetermined minimum spread. Then the method will calculate an offset value for each axis and calculate a sensor value for each axis. Then the method will calculate an azimuth value with the new sensor values and determine the heading using the azimuth.
    • 公开了一种在汽车电子罗盘内使用的自动校准方法。 该方法包括初始化变量,然后从至少两个轴检索传感器读数的步骤。 该方法然后将罗盘倾斜度与预定阈值进行比较。 接下来,该方法将确定传感器读数是否为当前校准周期的最小值或最大值。 接下来,该方法将确定传感器读数的最大值是否大于预定的最小值。 然后,该方法将计算每个轴的偏移值,并计算每个轴的传感器值。 然后,该方法将使用新的传感器值计算方位角值,并使用方位角确定航向。
