Abstract: A distributed gas detection system includes one or more hollow core fibers disposed in different locations, one or more solid core fibers optically coupled with the one or more hollow core fibers and configured to receive light of one or more wavelengths from a light source, and an interrogator device configured to receive at least some of the light propagating through the one or more solid core fibers and the one or more hollow core fibers. The interrogator device is configured to identify a location of a presence of a gas-of-interest by examining absorption of at least one of the wavelengths of the light at least one of the hollow core fibers.

Abstract: A pressure sensing cable in one embodiment includes a polarization maintaining (PM) optic fiber having a length; and a Fiber Bragg Grating (FBG) pair formed in the PM optic fiber. The FBG pair includes a first FBG formed at a location along the length of the optic fiber. The first FBG defines a first wavelength range at which the first FBG is reflective. The FBG pair also includes a second FBG spaced a distance from the first FBG to define a FBG cavity extending between the first FBG and the second FBG. The second FBG defines a second wavelength range at which the second FBG is reflective. The first wavelength range of the first FBG and the second wavelength range of the second FBG at least partially overlap.

Abstract: A pressure sensing cable in one embodiment includes an optical fiber having a first core and a second core. The first core extends along a length of the cable, and is sized and configured to provide propagation of light along the first core along the length of the cable. The first core has a first mode index corresponding to the speed of light propagation along the first core. The second core extends along the length, is spaced a distance from the first core, and is sized and configured to provide propagation of light along the second core along the length of the cable. The second core has a second mode index corresponding to the speed of light propagation along the second core. The second mode index is different from the first mode index, wherein light propagates along the second core at a different speed than along the first core.

Abstract: Some systems described herein include a frequency dependent phase plate for generating multiple phase-contrast images of a sample, each from a different frequency range of light, each phase-contrast image for frequency range of light formed from light diffracted by the sample interfered with undiffracted light that has a frequency-dependent baseline relative phase shift from the phase plate. In some embodiments, the multiple phase-contrast images may be used to generate a quantitative phase image of a sample. The phase-contrast images or the produced quantitative phase image may have sufficient contrast for label-free auto-segmentation of cell bodies and nuclei.

Abstract: A system includes a downhole tool having a housing and a passage extending through the housing, where the passage includes an inlet configured to receive a flow of a wellbore fluid and an outlet configured to discharge the flow of the wellbore fluid. The downhole tool includes a heating element configured to heat the flow of the wellbore fluid and to enable the flow of the wellbore fluid to transition to a single-phase fluid flow within the passage. The downhole tool includes a phase composition sensor positioned adjacent the passage and configured to provide feedback indicative of formation of the single-phase fluid flow. The system includes a controller configured to monitor a power consumption of the heating element and to determine an enthalpy of the wellbore fluid based in part on the power consumption and the feedback from the phase composition sensor.

Abstract: An accelerometer includes a membrane, an energy source producing a laser beam which is directed at the membrane causing it to vibrate, and a transparent cap disposed at one end of the energy source. The accelerometer includes a first controller for adjusting an output power of the energy source in a first feedback loop, a second controller for controlling the wavelength of the laser beam in a second feedback loop, and a detector sensing a reflected portion of the laser beam. An acceleration signal is based in part on the frequency of the reflected portion of the laser beam.
