A newly proposed articulating invention, each of whose four constituent embodiments is designed to trisect any of a multitude of suitably described angles by means of becoming properly set to its designated magnitude; thus automatically portraying a motion related solution for the trisection of an angle that discloses complete routing details of a pathway that leads from such designated magnitude all the way back to its trisector; thereby discerning the whereabouts of certain intersection points which evade detection when attempting to otherwise locate them by means of applying only a straightedge and compass to an angle of such designated magnitude; furthermore projecting finite lengths of any trisector that bears cubic irrational trigonometric properties, being those that cannot be duplicated, but only approximated, when applying a straightedge and compass to a given length of unity; and being of a unique design that could be adapted to function as a level.

Described herein is a detector for determining a position of at least one object. The detector includes: at least one transfer device; at least one illumination source adapted to generate at least one light beam for illuminating the object; at least one first optical receiving fiber and at least one second optical receiving fiber; at least two optical sensors; and at least one evaluation device being configured for determining at least one longitudinal coordinate z of the object by evaluating a combined signal Q from the sensor signals.

The present invention relates to a sensing system that, in a preferred embodiment, can be readily integrated into load-lifting structures (such as wings and landing gears) to provide real-time DPHM and obviate/mitigate catastrophic problems. Broadly, the present sensing system combines at least one shim portion with at least one nanogenerator such as a TENG or a PENG. A major advantage of the present sensing system is that it combines in a single structure the following functions: (a) gap management in the component in which the sensing system is installed, (b) collection/storage of measured data for the component in which the sensing system is installed, (c) harvesting/storing energy from operation environment of the component in which the sensing system is installed (e.g., DPHM data when the present sensing system is used for assessment of an aircraft's structural conditions), and (d) wireless transmission of measured data for the component in which the sensing system is installed to a user interface.

The disclosure relates to a method for fabricating a speckle for high temperature deformation measurement of a shaped refractory material. A technical solution includes mixing a hercynite micropowder and a liquid mixing agent in a mass ratio of (3-6):1, and ultrasonically treating to obtain a speckle mixture; polishing a surface of a shaped refractory material to be measured, removing impurities, and spraying the speckle mixture on the surface of the shaped refractory material to be measured with a pneumatic airbrush in a time hood to obtain an uncured speckle; heating the uncured speckle to 60-80° C., keeping for 1-3 h, then heating to 100-120° C., and keeping for 1-3 h to obtain a speckle for high temperature deformation measurement of a shaped refractory material. The fabricated product is suitable for high temperature deformation measurement of a shaped refractory material at 1,600° C.

A deformable structure includes a first deformable layer, and a material of the first deformable layer includes a deformable material. The deformable material includes a plurality of sheet structures that are stacked, and each sheet structure includes a plurality of aldolases. A molecular model of an aldolase is equivalent to a square on a plane where the sheet structure is located, and the aldolase has amino acid residues at each of four corners thereof. In one sheet structure, amino acid residues at four corners of each aldolase are connected to amino acid residues of four aldolases around the aldolase through four disulfide bonds, respectively. In two adjacent sheet structures, amino acid residues of two adjacent aldolases are connected through at least one disulfide bond.

A newly proposed articulating invention, each of whose four constituent embodiments is designed to trisect any of a multitude of suitably described angles by means of becoming properly set to its designated magnitude; thus automatically portraying a motion related solution for the trisection of an angle that discloses complete routing details of a pathway that leads from such designated magnitude all the way back to its trisector; thereby discerning the whereabouts of certain intersection points which evade detection when attempting to otherwise locate them by means of applying only a straightedge and compass to an angle of such designated magnitude; furthermore projecting finite lengths of any trisector that bears cubic irrational trigonometric properties, being those that cannot be duplicated, but only approximated, when applying a straightedge and compass to a given length of unity; and being of a unique design that could be adapted to function as a level.

A retrographic sensor includes a clear elastomer substrate, a deformable reflective layer, and a contact surface with an array of rigid, non-planar features formed of a material or a pattern of particles to mitigate adhesion to a target surface while permitting the egress of trapped air around a region of interest. This combination of features permits the contact surface of the sensor to more closely conform to the target surface while physically transferring the topography of the target surface to the deformable layer for imaging through the substrate.
