  • Publication number: 20210035748
    Abstract: A shape-memory alloy actuated switch (SMAAS) is provided that enables the stable switching of two separate circuits. The presently disclosed SMAAS includes a substrate, one or more electrical contacts attached to the substrate for connecting to load circuits, and one or more electrically conductive elements for selectively connecting the one or more electrical contacts. The disclosed SMAAS also includes one or more shape-memory alloy actuators attached to the substrate. The one or more shape-memory alloy actuators are configured to move the one or more electrically conductive elements. The shape-memory alloy actuators are self-heated by passing current through the shape-memory alloy material. The disclosed SMAAS may also include electrical contacts to connect an external control current to the shape-memory alloy material. In some examples, the provided SMAAS includes one or more retention mechanisms to prevent movement of the electrically conductive elements after actuation.

  • Patent number: 10790779
    Abstract: In some examples, a system comprises a first component; a second component configured to receive signals from the first component via one or more wires; and a controller. In at least some examples, the controller is coupled to the one or more wires and is trained with a classification model to distinguish between signals indicating arc events and signals not indicating arc events. In at least some example, the controller is further configured to: receive the signals; extract features that are at least partially related to the received signals; classify the extracted features using the classification model; determine an occurrence of the arc event based on the classification; and provide an output signal indicating an arc event.
