  • Publication number: 20250377337
    Abstract: An inspection system for inspecting a surface includes a macromanipulator including an inspection end configured to be disposed proximal to the surface. The inspection system further includes a micromanipulator coupled to the inspection end. The. micromanipulator includes a housing, a pair of guide rails at least partially disposed within and fixedly coupled to the housing, a probe support slidably coupled to the pair of guide rails, an actuating arm disposed within the housing and coupled to the probe support via a scotch yoke mechanism, and an actuating mechanism configured to rotate the actuating arm relative to the housing. The inspection system further includes a probe coupled to the probe support for inspecting the surface.

  • Publication number: 20250224382
    Abstract: A probe for non-destructive testing of a component. The probe includes a head configured to transmit a signal or a wave to a surface of the component for non-destructive testing of the component. The head includes a first head end facing away from the component and an opposing second head end facing the component. The probe further includes a tube spaced apart from the head and including a first tube end distal to the head and an opposing second tube end proximal to the head. The tube defines an internal passage therein extending between the first tube end and the second tube end. The probe further includes a flexible actuator disposed between the head and the tube. The flexible actuator is configured to be actuated between a non-actuated state and an actuated state.

  • Patent number: 11616939
    Abstract: An inspection system for mounting on a user's hand. The inspection system comprising: an imaging unit comprising two sub-units, the first sub-unit being configured to provide images from a first point of view and the second sub-unit being configured to provide images from a second point of view; and a measuring unit configured to provide data relating to a physical property measured at a measurement location on the user's hand. The imaging unit has a separation sensor configured to measure the separation between the two sub-units of the imaging unit. A method of inspecting and/or servicing a machine is also disclosed.
