    • Systems, methods, and apparatus for fault detection and interruption in power lines are provided. Circuitry is implemented via software and hardware that is configured to sense an operational aspect of a power line, such as current levels in a three-phase power line, and apply signal processing to the sensed operational aspect to detect faults including different types of faults such as transient and steady state faults and can also be configured to identify the type of fault. Information on the fault and the identification of the type of fault can be displayed, stored, or some other output operation can be implemented. Circuitry can be implemented to provide digital signal processing and analog signal processing to, for example, independently and in parallel (e.g., redundant operation) detect faults and respond to faults as they occur (i.e., in real time).
    • 提供了用于故障检测和电源线中断的系统,方法和装置。 电路通过被配置为感测电力线的操作方面(例如三相电力线中的电流水平)的软件和硬件来实现,并且对感测的操作方面应用信号处理以检测包括不同类型的故障的故障,例如 作为瞬态和稳态故障,也可以配置为识别故障类型。 关于故障信息和故障类型的识别可以进行显示,存储或其他一些输出操作的实现。 可以实现电路以提供数字信号处理和模拟信号处理,以例如独立地并行地(例如,冗余操作)检测故障并且在发生故障时(即实时地)响应故障)。

    • A surgical instrument for shaping the distal femur of a patient to receive a unicondylar prosthetic component includes a cutting guide body that carries a pair of cylindrically shaped openings in the guide body, each of the openings having a central longitudinal axis and the respective axes of the openings forming an acute angle. An annular bushing is removably received in a selected one of the cylindrical openings during a cutting of the distal femur. A bone cutting reamer registers with a central cylindrical opening in the bushing. The bone cutting reamer has an annular shoulder that abuts the top of the bushing to define the depth of cut. During use, the surgeon positions the cutting guide body over a diseased condyle of the patient's distal femur. The surgeon then sequentially places the bushing and its associated bone cutting reamer into one of the selected openings of the cutting guide body. After placing the bone cutting reamer in the second opening of the guide body, the surgeon has formed two overlapping circular cuts which form an elongated oval shaped and three-dimensionally convex surface for receiving the unicondylar prosthesis.
    • 用于成形患者的远端股骨以接收单髁假体部件的手术器械包括切割引导体,该引导体在引导体中承载一对圆柱形的开口,每个开口具有中心纵向轴线和相应的轴线 开口形成锐角。 在切割远端股骨期间,环形衬套可移除地容纳在选定的一个圆柱形开口中。 骨切割铰刀与衬套中的中心圆柱形开口配准。 骨切割铰刀具有环形肩部,其邻接衬套的顶部以限定切割深度。 在使用期间,外科医生将切割引导体定位在患者的远端股骨的患病髁上。 然后外科医生顺序地将套管及其相关的骨切割扩孔器放置在切割引导体的所选择的开口之一中。 在将骨切割铰刀放置在引导体的第二开口中之后,外科医生已经形成两个重叠的圆形切口,其形成用于接纳单髁假体的细长的椭圆形和三维凸面。
