摘要： A magnetic drive device couples the drive motor of a depth control device or bird, with the axle of the depth control wings. The magnetic drive includes a plurality of permanent magnet pieces mounted in respective drive blocks on either side of a magnetically permeable membrane of the main body of the drive mechanism. The magnet pieces are mounted side by side in alternating polarity to capture as much of the magnetic flux of the magnets as possible to minimize stray flux from escaping the drive. Pole pieces either side of the drive blocks also serve to capture stray flux. To the maximum extent possible within the constraints of mechanical durability, the drive mechanism is made of non-magnetic or non-ferrous materials which would interfere with the heading sensor of the bird. Thus, this invention avoids reducing the accuracy of the heading sensor of the bird, while eliminating a major source of seawater inleakage into the bird.
摘要翻译：磁驱动装置将深度控制装置或鸟的驱动马达与深度控制翼的轴连接。磁驱动器包括安装在驱动机构的主体的导磁膜两侧的相应驱动块中的多个永磁体片。这些磁片以交替的极性并排安装，以尽可能多地捕获磁体的磁通量，以最大限度地减少从驱动器逸出的杂散磁通。驱动块的两侧的极片也用于捕获杂散通量。在机械耐久性的限制内，在最大程度上可能的是，驱动机构由非磁性或有色金属材料制成，这将干扰鸟的航向传感器。因此，本发明避免了降低鸟的航向传感器的准确性，同时消除了主要的海水泄漏入鸟。

摘要： A battery charging apparatus and method permits the recharging of the batteries of a seismic streamer depth control device or bird without access to the interior of the bird. In a preferred embodiment, a battery pack includes a coil within the bird that is capable of receiving a charging field from a charging unit by inductive coupling. The coil provides power to a regulated power supply comprising a voltage regulator and rectifier, and direct current is provided to charge battery cells. Thus, the batteries within the bird a charged by induction from outside the casing of the bird. Alternatively, the battery pack may be detached from the rest of the bird, but the battery pack remains scaled against the elements. The battery pack may include an electrical connector which attaches to the main body of the bird, and the electrical connector includes one or more pins for charging purposes. When the battery pack is detached from the main body of the bird and placed in a storage rack, the electrical connector of the battery pack mates with an outlet and the battery pack is charged through the regulated power supply.
摘要翻译：电池充电装置和方法允许对地震拖缆深度控制装置或鸟类的电池进行充电，而不进入鸟的内部。在优选实施例中，电池组包括鸟内的线圈，其能够通过电感耦合从充电单元接收充电场。线圈为包括电压调节器和整流器的稳压电源提供电力，并且提供直流电以对电池单元充电。因此，鸟中的电池通过从鸟的外壳外部感应而被充电。或者，电池组可以从鸟的其余部分分离，但是电池组保持与元件相比较。电池组可以包括连接到鸟的主体的电连接器，并且电连接器包括用于充电目的的一个或多个销。当电池组从鸟的主体分离并放置在存放架中时，电池组的电连接器与出口配合，电池组通过稳压电源充电。
