摘要： Aspects described herein provide structures for a force sensor, and force sensors using such structures, which are compact and easy to manufacture, for example by 3D printing. In particular the structures comprise a pair of stacked ring sensor elements, the ring sensor elements in turn being formed by upper and lower ring elements joined together at points around the circumference thereof by resiliently mounted connection bars. The connection bars may extend in the same plane as the rings, in which case sensitivity to torque about the axis of the rings is much reduced, such that a five-axis sensor is effectively obtained, or the connection bars may extend obliquely between the upper and lower rings of each sensor element, such that they have a directional component in the direction of the axis of the rings (the rings of each element being co-axially stacked). In this second case application of a torque about the ring axis causes the oblique connection bars to either increase or decrease their directional component in the axial direction, thus providing sensitivity to torque about the axis, and providing a compact six axis sensor.

摘要： A fiber optic force sensing assembly for detecting forces imparted at a distal end of a catheter assembly. The structural member may include segments adjacent each other in a serial arrangement, with gaps located between adjacent segments that are bridged by flexures. Fiber optics are coupled to the structural member. In one embodiment, each fiber optic has a distal end disposed adjacent one of the gaps and oriented for emission of light onto and for collection of light reflected from a segment adjacent the gap. The optical fibers cooperate with the deformable structure to provide a change in the intensity of the reflected light, or alternatively to provide a variable gap interferometer for sensing deformation of the structural member. In another embodiment, the gaps are bridged by fiber Bragg gratings that reflect light back through the fiber optic at central wavelengths that vary with the strain imposed on the grating.

摘要： A component has an integrated sensor device for an optical, multi-axis measurement of a force applied to the component. The component includes a cavity and a first support element having one or more first optical elements and a second support element having one or more second optical elements. The first support element and the second support element are formed in the cavity and partially inserted into the component. A transmission device generates at least two beams in independent directions when connected to a power source. The beams pass through the cavity between the first optical elements and the second optical elements. The first optical elements and the second optical elements are adapted to generate information about a relative positional change of the first support element with respect to the second support element based on the at least two beams. The transmission device provides the information for measuring the force application.

摘要： A device for providing pipelaying guidance is disclosed. The device may determine an original shape of a pipeline that comprises a plurality of pipeline segments. The device may obtain current location data concerning a respective position of each pipeline segment of the plurality of pipeline segments, and may determine a current shape of the pipeline based on the current location data. The device may calculate, based on the original shape of the pipeline and the current shape of the pipeline, stress information concerning the pipeline, and may perform one or more actions based on the stress information.

摘要： Achieving high spatial resolution in contact sensing for robotic manipulation often comes at the price of increased complexity in fabrication and integration. One traditional approach is to fabricate a large number of taxels, each delivering an individual, isolated response to a stimulus. The proposed sensors include a continuous volume of soft material, e.g., a transparent polymer, and light emitting diodes configured to emit light into the transparent volume that can be received by photodetectors. The location and depth of indentations can be measured between all pairs of light emitting diodes and photodetectors in the set, and this rich signal set can contain the information needed to pinpoint contact location with high accuracy using regression algorithms.

摘要： A method for detecting and measuring a clamping force and/or a braking torque includes encapsulating a fiber-optic strain sensor in a casing and incorporating the casing in a portion of friction material adhering to a base platform of a brake pad, detecting, by the fiber-optic strain sensor, a first strain in a first position of the casing along a first direction and a second strain in a second position of the friction material along a second direction, generating a first photonic signal, representative of the first detected strain, and a second photonic signal, representative of the second detected strain, receiving the first and second photonic signals, by an optical reading/interrogation unit, optically connected to the fiber-optic strain sensor, determining, by the optical reading/interrogation unit, the values of the first and second strains based on the first and second received photonic signals and determining a measurement of the clamping force and/or braking torque based on determined values of the first and second strains.
