Abstract: A method of analyzing a load bearing member (12), comprises providing the load bearing member in a condition in which it is secured to a formation with a securing assembly (14). A predetermined load is applied to the load bearing member, thereby stressing the securing assembly. A signal is transmitted through a component (24, 108) of the securing assembly transverse to the direction at which the load is applied, and a measurement is taken of an effect on the signal to determine the aforesaid load.

Abstract: A tactile sensor unit is provided, which includes a substrate; a coat formed on the substrate; and a cantilever beam structure having one end fixed to the substrate and curved to rise in such a direction that the other end of the cantilever beam structure is farther from the substrate than the one end. The tactile sensor unit detects a load applied to the coat. The cantilever beam structure is capable of resonating at a first resonant frequency and a second resonant frequency which is different from the first resonant frequency. The tactile sensor unit further includes a computation section for calculating a directional component of the load based on a change ratio of the first resonant frequency obtained in accordance with a change in the load and a change ratio of the second resonant frequency obtained in accordance with the change in the load.

Abstract: Novel configurations for a miniature vibrating beam mechanical resonator provide low energy transfer to a supporting structure and low sensitivity to mounting misalignment. A symmetric suspended portion includes two vibrating beams that vibrate normal to a quiescent plane of the resonator, 180 degrees out of phase relative to one another. The vibrating beams are attached, at least at one end, to a torsional coupling element that is joined to a mounting pad along a non-translating suspension boundary. Counterbalances are attached to the vibrating beams, and the resonator is configured such that dynamic forces and moments coupled to each torsional coupling element from the vibrating beams are balanced along each nominal non-translating suspension boundary proximate to the symmetry axis and along the symmetry axis proximate to each nominal non-translating suspension boundary. Each non-translating suspension boundary is a torsional axis for a twisting deformation of the first torsional coupling element.

Abstract: A planar single-piece measuring string which is designed to oscillate transversely to the plane defining its rest position has two attachment tabs, a resonating string section, two coupling sections connecting the resonating string section to the attachment tabs, and two defined nodal domains where the resonating string section meets the coupling sections. The measuring string includes at each nodal domain a pair of elastic flaps. The elastic flaps extend parallel to the resonating section and participate in the oscillation of the string. The elastic flaps are connected on one side thereof to the nodal domains and the free ends of the flaps are located at a distance opposite each other. The flaps have the same thickness as the other portions of the measuring string.

Abstract: A system comprises a pair of straps which are preferably hinged and are arranged to be clamped around a structure, for example, a tubular member to be strain gauged, and secured, for example, by a single swing bolt with a diver sized hand knob. Across these two straps are a number of, for example, two sets of four equally spaced arranged strain gauge assemblies, aligned along the longitudinal axis of the tubular member. Vibrating wire strain gauges are uniformly suspended by compression springs from a protective cover. Because such compression springs are relatively free to move laterally by small amounts, they do not significantly increase the axial stiffness of the strain gauge. The protective cover is attached to the two clamping straps by set bolts with diver sized hand knobs. When tightened the strain gauge will be pressed onto the member surface with the pre-determined spring force. The protective cover is skirted by sealing, which, after installation will seal around the gauges offering complete mechanical protection plus protection from marine fouling.
