Patent ID: 7950298

Claim:
A bracelet assembly for moving sensor modules around a pipe, comprising: a frame adapted for installation around the pipe, the frame having a circular shape and a pair of circular members spaced apart from each other; supports adapted to receive the sensor modules; a sliding arrangement slideably mounted onto the frame and guiding a displacement of the supports in periphery of the pipe, the sliding arrangement comprising attachments spaced apart from one another and receiving the supports in periphery of the pipe, the sliding arrangement comprising a slideable member to which the supports are attached, and a guide member extending on the frame and slideably receiving the slideable member for sliding along a predetermined sliding range of the peripheral course, the guide member being provided on one of the circular members, the slideable member having an arc shape and extending between the circular members, one of the guide member and the slideable member having elongated grooves extending concentrically with respect to the peripheral course, the other of the guide member and the slideable member having pins engaging in the grooves; a first driving means for controllably driving the sliding arrangement and thereby displacing the supports in periphery of the pipe at desired operating positions; biasing means for biasing the sensor modules against the pipe; wheel arrangements distributed around the frame and projecting therefrom for engagement with the pipe and displacement of the frame along an axial direction of the pipe; and a second driving means for controllably driving the wheels in rotation and thereby displacing the frame along the axial direction of the pipe at a desired operating position.
