  • Patent number: 12182479
    Abstract: An inspection system for in situ evaluation of an additive manufacturing (AM) build part is provided. The inspection system comprises a build plane induction coil sensor configured and positionable so that during construction of the build part, the sensor's magnetization and sensor coils surround at least the last-produced layer of the AM build part in the build plane. The inspection system further comprises an energization circuit and a central processing system. The central processing system comprises a communication processor configured for sending command signals to the energization circuit and receiving impedance data from the build plane induction coil sensor, and energization controller configured for determining energization commands for transmission to the energization circuit, and an induction data analyzer configured for processing build part impedance data using complex impedance plane analysis and for identifying anomalies in the AM build part.

  • Patent number: 9493327
    Abstract: A portable lifting device is provided that includes a pair of telescoping parallel beam assemblies attached on either end to a pair of stanchion assemblies. Each stanchion assembly includes a top and bottom member as well as at least one vertical member. The bottom member of each beam assembly rests on a deck support member, and the height of each vertical member may be adjustable. A sliding guide assembly is slidably mounted on the parallel beam assemblies and includes a cross-member between the parallel beams that acts as the connection point for a lifting medium. This allows for a higher support point for the lifting medium than would be provided by a conventional single-beam device.
