  • Publication number: 20260003013
    Abstract: Disclosed are power distribution systems and methods in which a power distribution unit (PDU) includes a residual current monitor (RCM) to detect the presence of downstream leakage current in the PDU. The RCM can include a current sensor with a core that has power conductors passing through the core and drive windings about the core. Drive circuitry of the RCM produce alternating drive signals through the drive windings to drive the core into and out of positive and negative saturation. Sensing circuitry of the RCM produce a response signal that is filtered by a high-order current signal filter to isolate characteristics of the downstream leakage current.

  • Patent number: 12493149
    Abstract: The present disclosure provides improved optical devices (e.g., discrete passive optical devices), and improved systems/methods for fabricating such optical devices. Systems/methods are provided for fabricating discrete passive optical devices by utilizing an advantageous cyclic core variance fabrication process/method. The cyclic core variance process/method employs a continuous process, but instead of having one constant core profile of the optical fiber, the core profile of the optical fiber varies cyclically, going back and forth between two or more core profile zones, with a gradual and properly-shaped transition zone in between. The core profile zones and transition zone can be custom formed (e.g., user-defined) to fabricate a variety of optical effects of the optical devices as desired, allowing a large variety of optical devices to be fabricated utilizing the exemplary cyclic core variance process/method.
