This invention relates to force/torque sensor and more particularly to multi-axis force/torque sensor and the methods of use for directly teaching a task to a mechatronic manipulator. The force/torque sensor has a casing, an outer frame forming part of or connected to the casing, an inner frame forming part of or connected to the casing, a compliant member connecting the outer frame to the inner frame, and one or more measurement elements mounted in the casing for measuring compliance of the compliant member when a force or torque is applied between the outer frame and the inner frame.

A force sensor includes a substrate, a plurality of sensing elements, and a plate. The substrate includes a central aperture extending along a longitudinal axis of the substrate, and has a proximal surface, a distal surface, a first side surface, a second side surface, a top surface, and a bottom surface. A recess is defined in at least one of the distal surface, the first side surface, the second side surface, the top surface, or the bottom surface of the substrate. The plurality of sensing elements are disposed within the recess, and the plate is disposed over the recess and mounted to the substrate to hermetically seal the plurality of sensing elements within the substrate.

A coupling member for coupling a solidified body and a structural member includes a sensor part that is capable of measuring physical variation resulting from external force and is for detecting information that will help determine whether there is an abnormality in the solidified body and/or structural member. The coupling member has an embedded part at one end that is embedded in the solidified body and/or ground and has a fixing part that is on the side of the other end extending outside of the solidified body and is capable of fixing the structural member.

An apparatus and method for inspection of at least one of grass, artificial turf, infill, or dirt, on a surface, using optical photographic images from a camera and three-dimensional (“3D”) depth scans using the camera and one or more laser, to create a mask to distinguish aspects of the surface, so that the surface can be measured and analyzed.

A method of estimating torque includes disposing at least one measurement assembly at a downhole component, the at least one measurement assembly including a first set of directional sensors disposed at a first axial location along the downhole component, and a second set of directional sensors disposed at a second axial location along the downhole component. The method also includes collecting directional measurement data from the first set of directional sensors and the second set of directional sensors during rotation of the downhole component, and estimating, by a processing device, an amount of torque on the downhole component based on the directional measurement data.

Disclosed are an apparatus and method for adjusting a steering wheel, the apparatus including an image capturing unit configured to capture images of a current state of a steering wheel at multiple angles, an analysis unit configured to create leveling information on zero adjustment of the steering wheel by processing the image acquired by the image capturing unit, and a control unit configured to calculate an error from preset reference leveling information depending on the leveling information created by the analysis unit and performing the zero adjustment on the steering wheel by controlling a drive unit for operating the steering wheel depending on the calculated error.

A collision detection apparatus includes a bumper beam, an absorber, a collision detection sensor, and a bumper cover. The bumper beam extends in a vehicle width direction. The absorber is disposed adjacent to a vehicle front side of the bumper beam. The collision detection sensor includes a pressure tube extending in the vehicle width direction and held by the absorber and is configured to output a signal corresponding to a pressure change in the pressure tube. The bumper cover is disposed on a vehicle front side of the absorber. The bumper cover includes: a low rigidity part disposed at a position lower than the pressure tube; and a high rigidity part having a bending rigidity higher than a bending rigidity of the low rigidity part, disposed at a position above the low rigidity part, and having an upper end at a position higher than the pressure tube.

Embodiments within the scope of the present disclosure are directed to external sensor kits that may be included in new injection molds or retrofitted into existing injection molds in order to approximate conditions within a mold, such as pressure or the location of a melt flow front. Such kits are designed to amplify meaningful measurements obtained by the external sensor kit so that noise measurements do not prevent the approximation of conditions within a mold. In some embodiments within the scope of the present disclosure, an external sensor kit includes a strain gauge sensor, a coupon, a support bracket, and a hammer. The strain gauge sensor is placed on a surface of the coupon and measures the strain in the coupon.
