  • Publication number: 20210302384
    Abstract: The present disclosure provides a system with an ultrasonic transducer housing assembly that maintains an acoustic coupling path for spherically focused transducers while allowing the placement of the housing at angles relative to a vertical angle. This invention extends the use of spherically focused transducers into portable systems with significantly reduced system and operational costs for non-destructive testing. The transducer housing assembly features a lens housing with an opening that is sealed with a replaceable fluid-tight membrane defining an acoustic window with acoustic properties similar to those of fluid in the housing and therefore at least translucent to the transducer and causing minimal signal loss. The housing contains minimal fluid to be cleaned up in case of improper use or leakage. The transducer housing also includes an optional surface offset and an ability to adjust the focal point of the transducer relative to the component surface.

  • Publication number: 20200355593
    Abstract: The present disclosure provides a low-cost and accurate rheometer system and method capable of determining melt flow rheological properties of polymers, such as from Fused Filament Fabrication (“FFF”) polymeric materials. The device can include a filament feeding system, liquefier for filament melting, force transducer for measuring filament feeding force, and a temperature control system for controlling polymer melt temperatures. An electronic control system can capture data and manage operations. The system can measure a filament velocity and filament force required to extrude the FFF filament for printing. The filament velocity and force data can be used to compute data sets of melt volumetric flow relative to pressure drop across a FFF nozzle.

  • Patent number: 8680911
    Abstract: A clamp-point active circuit is provided. The clamp-point active circuit includes a rate amplifier configured to receive an output from a device transitioning between at least two levels. The clamp-point active circuit has at least one switching device configured to receive an output from the rate amplifier. The at least one switching device is in at least one respective feedback loop of the rate amplifier. A switching of the at least one switching device causes the rate amplifier to amplify with high linearity in a desired operating range and to clamp outputs received from the transitioning device that are outside the desired operating range to a fixed level.
