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： In an embodiment, a relative deflection detector may include at least two structural arcs, and a predetermined number of means for measuring position capable of determining the relative deflection in a first component. The at least two structural arcs may be for example, comprised of a first and second structural arc whereby the first and second structural arcs are attached to the first component at respective first and second predetermined locations and whereby each arc is comprised of a respective sequence of indicators, such as, for example, codes inscribed on the outer circumference of each arc. The first and second structural arcs may be positioned in concentric and coplanar relationship with each other. The predetermined number of sensors may be comprised of a first and second optical encoder sensor each positioned in proximate and coplanar relationship with the first and second structural arcs so as to read the first sequence of codes, second sequence of codes, or both, and thereby detect positions of each structural arc (e.g., a first position corresponding to the first structural arc and a second position corresponding to the second structural arc). The first and second positions may be used to calculate and thereby determine a relative deflection of the first component.

摘要： A first angle acquiring unit acquires a rotational angle of a characteristic portion in a predetermined region on an inlet side of an insertion member of a linear body extending through the insertion member. From an image of the linear body inserted into a body of a subject, a second angle acquiring unit acquires a direction of a curved portion of the linear body inserted into the body of the subject and then acquires a rotational angle of a distal end of the linear body. A torque calculation unit calculates a torque based on a difference between the rotational angle in the predetermined region acquired by the first angle acquiring unit and the rotational angle of the distal end of the linear body acquired by the second angle acquiring unit.

摘要： Sensors operate by resolving changes in orientation of a wavelength dependent structure with respect to a reference direction determined by an incident light beam, resulting in very high sensitivity and dynamic range. Said sensors are wavelength encoded, can be multiplexed in a single light path such as an optical fiber, yet are decoupled mechanically from the fiber, resulting in high stability.

摘要： The present invention provides a method and apparatus for applying a uniformly-distributed pattern of stripes (8) on a component (6) of a large rotary machinery, such as an industrial generator. A method is provided that comprises measuring the circumferential area of the component (6) with a measuring element (14). The precise circumference is indicated and a desired number of pattern segments is determined. The circumference is divided by this number to produce equally spaced segments. This is then transferred to the rotor shaft (6) by marking on the measuring element (12) the number of segments and making a copy of the markings onto a second strip (14). These strips are then aligned on the circumferential area and cross strips (22) are placed at each of the segment marks (16). The segment areas not covered by the cross strips (24) are then painted in a color that is optically distinguishable from the non-painted regions. An optical probe (2) is then able to scan the stripes to detect torsional forces in the rotor shaft.
