    • A magnetic recording disk drive uses a disk having pre-patterned servo sectors extending generally radially across the data tracks. The servo sectors include at least two position error signal (PES) bursts or fields. The phases of the PES fields in the servo readback signal are demodulated to generate a PES to control the disk drive actuator for positioning the read/write heads. Each field contains generally radially directed magnetized stripes, with each stripe comprising a plurality of discrete radially-spaced generally parallelogram-shaped islands, each island having its length oriented at an acute angle relative to a track centerline. The stripes have alternating polarity of magnetizations in the along-the-track direction. In one implementation there are four fields: a first pair of fields A and B wherein the pattern of the radial stripes in field A is the mirror image about a radial line of the pattern of the radial stripes in field B, and a second like pair of fields C and D, but wherein the radial stripes in fields C and D are shifted radially from the radial stripes in fields A and B.
    • 磁记录磁盘驱动器使用具有预先构图的伺服扇区的磁盘,该磁盘扇区通常径向延伸穿过数据磁道。 伺服扇区包括至少两个位置误差信号(PES)突发或场。 对伺服回读信号中的PES场的相位进行解调,生成PES以控制用于定位读/写头的磁盘驱动器致动器。 每个场包含大致径向定向的磁化条纹,每个条带包括多个离散的径向间隔的大致平行四边形形状的岛,每个岛的长度相对于轨道中心线以锐角取向。 条纹沿磁迹方向具有磁化的交替极性。 在一个实现中,存在四个场:第一对场A和B,其中场A中的径向条纹的图案是关于场B中的径向条带的图案的径向线的镜像,以及第二对对 的场C和D,但是其中场C和D中的径向条纹在场A和B中的径向条纹中径向偏移。

    • An electric golf cart that repeatedly travels around a given course of golf links is powered by a driving motor supplied with electric power from a driving battery. The electric golf cart is provided with a travel distance integrating unit, a memory, a battery charge and discharge integrating unit, and a discharge-per-course calculating unit. Mapping data is stored in the memory, which mapping data defines the relationship between the distance that the electric golf cart travels and the number of rounds that the electric golf cart has traveled. The number of rounds that the electric golf cart has traveled is calculated by the discharge-per-course calculating unit based on the travel distance obtained by the travel distance integrating unit along with the mapping data. Then, the number of rounds obtained and the discharge calculated by the battery charge and discharge integrating unit are utilized to identify the discharge of the driving battery per course.
    • 重复行进的电动高尔夫球车在给定的高尔夫球场环路的驱动下由驱动电动机驱动,驱动电机由驱动电池供电。 电动高尔夫球车设置有行驶距离积分单元,存储器,电池充放电积分单元和每路课程计算单元。 映射数据被存储在存储器中,该映射数据定义了电动高尔夫球车行进的距离与电动高尔夫球车行进的回合数之间的关系。 基于由行驶距离积分单元获得的行驶距离以及映射数据,通过每路课程计算单元计算出电动高尔夫球车行驶的回合数。 然后,利用获得的回合次数和由电池充放电积分装置计算出的放电量来确定每个课程的驱动电池的放电。
