Abstract: A reflective element for directing an optical signal into a fiber optic sensor having an optical fiber includes a plane containing a sharply defined straight line that separates between a first area of low reflectivity and a second area of high reflectivity. The plane is disposed parallel to a free end surface of the optical fiber so that the free end surface intersects the line of the reflective element, whereby relative movement between the free end surface of the optical fiber and the line in response to a physical change sensed by the fiber optic sensor induces variations in an optical signal reflected by the reflective element through the optical fiber, which variations allow measurement of the physical change.

Abstract: Methods for covalently modifying surfaces of various substrates are disclosed, along with various substrates having surfaces modified by such methods. Candidate surfaces include various polymeric, siliceous, metallic, allotrophic forms of carbon, and semiconductor surfaces. The surfaces are exposed to a reagent, having molecules each comprising a nitrenogenic group and a functionalizing group, in the presence of energized charged particles such as electrons and ions, photons, or heat, which transform the nitrenogenic reagent to a nitrene intermediate. The nitrene covalently reacts with any of various chemical groups present on the substrate surface, thereby effecting nitrene addition of the functionalizing groups to the substrate surface. The functionalizing groups can then participate in downstream chemistry whereby any of a large variety of functional groups, including biological molecules, can be covalently bonded to the surface, thereby dramatically altering the chemical behavior of the surface. Such functionalizations of the surface can be done in a single reactive step or in multiple reactive steps.

Abstract: A fiber optic sensor for detecting the presence or concentration of particular chemical or biological species in a zone to be monitored has light-emitting and detecting elements such as a gallium arsenide light-emitting diode and a Schottky diode light detector provided in a semiconductor body, and has an optical fiber formed in situ on a surface of the body to conduct light from the light-emitting diode to the detector. The fiber has a long light-transmitting core of a material such as silicon dioxide deposited on a semiconductor body surface and defined by photolithographic techniques and has a cladding deposited over and around the core of a material of relatively lower refractive index than the core. The cladding material reacts when contacted by the particular chemical or biological species to produce measurable changes in transmission of light through the fiber so that the detector provides an electrical signal representative of the presence or concentration of the species.

Abstract: A method may include determining a thermal signal for a thermal analysis of a rock sample. The method may further include transmitting various commands to various thermal sources to produce various heat emissions. A respective command among the commands may cause a respective thermal source among the thermal sources to produce a respective heat emission based on the thermal signal. The method further includes determining distributed temperature data of the rock sample using various distributed temperature sensors in response to producing the heat emissions. The distributed temperature sensors may be coupled to the rock sample on a first rock surface and a second rock surface. The first rock surface may be on an opposite side of the rock sample from the second rock surface. The method may further include determining predicted thermal property data of the rock sample using the distributed temperature data and a machine-learning model.
