    摘要： Systems, methods, and devices are provided for aligning a reference axis of an accelerometer with a measurement axis of a machinery component. An adaptor including a mounting plate, a plate stud integrated within the mounting plate, and a screw can be coupled to an accelerometer to ensure proper alignment of the reference axis of the accelerometer with the measurement axis of the machinery component. Aligning the reference axis and the measurement axis using the adaptor ensures that the axial orientation of the vibration data collected by the accelerometer properly corresponds to the intended axis of measurement of the machinery component and thus allows for consistent, repeatable installations of the accelerometer onto the machinery component without introducing alignment errors which can generate erroneous vibration data with respect to one or more axes of measurement.

    摘要： The proposed morphable sheet structure comprises a succession of adjacent flexible elongated rods (10) laterally connected to each other defining a sheet structure (1), each rod (10) defining a longitudinal axis (A); wherein the rods (10) are grouped in pairs, each pair of adjacent rods (10) are connected to each other through a first connector (11) tightly connected to a second connector (12) complementary with the first connector (11), being the first connector (11) part of one rod (10) of said pair of adjacent rods (10) and being the second connector (12) part of the other rod (10) of said pair of adjacent rods (10); being the first connector (11) and the second connector (12) slidably movable to each other in the direction of the longitudinal axis (A); the first connector (11) and/or the second connector (12) extending along the entire longitude of the rod (10).
