  • Patent number: 10797221
    Abstract: Assemblies for an ultrasonic probe and manufacturing methods are presented. In one example, the method includes additively forming first portions of the assembly using a first material with first acoustic properties and second portions of the assembly using a second material with second acoustic properties, the first and second acoustic properties being configured to modify ultrasonic signals of the ultrasonic probe. In another aspect, a housing for an ultrasonic probe is presented. The housing includes additively-formed portions, a fluid channel, and at least one cavity. The first additively-formed portions include a first material with first acoustic properties. The second additively-formed portions include a second material with second acoustic properties. The first and second acoustic properties are configured to modify ultrasonic signals of the ultrasonic probe. The fluid channel is for receiving fluid within the housing of the ultrasonic probe.

  • Patent number: 10684261
    Abstract: An inspection system for performing an inspection of an end region of a part is provided. The inspection system includes a robotic assembly positioned along a side of the part. The inspection system includes an ultrasonic probe coupled to the robotic assembly and positioned in proximity to the end region of the part. The ultrasonic probe is moved by the robotic assembly along a path to inspect the end region of the part. During the inspection, the ultrasonic probe transmits a signal towards the end region of the part and receives a reflected signal from the end region of the part. The inspection system provides, as a single system, for inspection of both a body of the part and the end region of the part.

  • Patent number: 8541904
    Abstract: An apparatus includes a DC-link, a voltage converter, a bus voltage controller, and a supervisory controller. The voltage converter is configured to convert a first DC voltage into a second DC voltage based on a command signal and based on an adjustment signal and to supply the second DC voltage to the DC-link. The bus voltage controller is configured to iterate calculation of the adjustment signal to communicate each iterated calculation of the adjustment signal to the voltage converter. The supervisory controller is configured to iterate calculation of the command signal and to communicate each iterated calculation of the command signal to the voltage converter and to the bus voltage controller. A frequency of the bus voltage controller to communicate each iterated calculation of the adjustment signal is higher than a frequency of the supervisory controller to communicate each iterated calculation of the command signal.
