  • Porous Structures Produced By Additive Layer Manufacturing
    Publication number: 20250058514
    Abstract: A three-dimensional structure is formed when layers of a material are deposited onto a substrate and scanned with a high energy beam to at least partially melt each layer of the material. Upon scanning the layers at predetermined locations at least a first segment overlapping a second segment and underlapping a third segment is formed.

  • Fault protection devices and related reclosing methods
    Patent number: 11101641
    Abstract: Fault protection devices for electrical distribution systems and related reclosing methods are provided. One exemplary method of reclosing a switching element of a fault protection device after fault detection involves pulsing the switching element closed to enable a temporary current flow through the fault protection device and verifying absence of a fault condition based at least in part on the temporary current flow using a testing fault detection threshold. After verifying the absence of the fault condition, the method closes the switching element to enable current flow through the fault protection device, monitors the current flow through the fault protection device for the fault condition using the testing fault detection threshold for a transition period, and monitors the current flow through the fault protection device for the fault condition using a different fault detection threshold after the transition period.
