    • Methods and systems of extending battery life of remote battery-operated timekeeping devices by minimizing the number of required synchronizations per unit of time needed to maintain a predetermined accuracy of the devices. The number of synchronizations are minimized by first calculating a time error rate between the remote timekeeping device and a master device over a sample period. Then, a synchronization is delayed and the remote timekeeping device is compensated based on the time error rate. The compensation delays the need for a synchronization yet maintains the predetermined accuracy of the remote timekeeping device. In some embodiments, the remote timekeeping device is compensated and multiple synchronizations are delayed before a new synchronization is necessary to maintain the predetermined accuracy.
    • 通过最小化维持设备的预定精度所需的每单位时间所需的同步数来延长远程电池供电的计时装置的电池寿命的方法和系统。 通过首先在采样周期之后计算远程计时装置与主装置之间的时间误差率来最小化同步数。 然后,延迟同步,并且基于时间错误率补偿远程计时装置。 该补偿延迟了同步的需要,同时保持了远程计时装置的预定精度。 在一些实施例中,在需要新的同步以维持预定精度之前补偿远程计时装置并且延迟多个同步。

    • There is disclosed a method of laser welding a number of coated metal sheets including the steps of: providing the coated sheets to be joined, and creating a raised region on at least one of the coated sheets. The raised region is formed on a first surface of the metal sheet while the second opposite surface of the sheet remains continuous and uninterrupted. A laser is then applied forming a weld joint where gases produced during the forming of the laser weld escape via the at least one embossment. In an alternative embodiment fine particles may be distributed on the surface of one or both of the sheets of coated metal to introduce a gap for the gases produced during the forming of the laser weld a place to escape. Preferably the fine particles will be zinc dust to maintain the coating between the two sheets to be joined.
    • 公开了一种激光焊接多个涂覆的金属板的方法,包括以下步骤:提供待接合的涂层片材,并在至少一个涂布片材上形成凸起区域。 凸起区域形成在金属板的第一表面上,而片材的第二相对表面保持连续且不间断。 然后施加激光器形成焊接接头,其中在激光焊接成形期间产生的气体经由至少一个压纹件逸出。 在替代实施例中,细颗粒可以分布在涂覆金属片中的一个或两个的表面上,以在形成激光焊缝期间产生的气体引入间隙以逃脱。 优选地,细颗粒将是锌粉,以保持要接合的两片之间的涂层。
