Abstract: Systems and methods for monitoring underwater structures are provided. First and second sets of point cloud data that are obtained at different times are compared to determine whether the location of the underwater structure has changed. For detecting vibration, a series of range measurements taken along a line intersecting the underwater structure are compared to one another to determine an amplitude and frequency of any vibration present in the underwater structure. For detecting temperature, the ratio of different components of return signals obtained from a point in the water surrounding the underwater structure is measured to derive the temperature of the water. Leak detection can be performed by scanning areas around the underwater structure. Monitoring systems can include a primary receiver for range measurements, and first and second temperature channel receivers for temperature measurements.

Abstract: A device may include a first infrared sensor, a second infrared sensor, a temperature detecting component, and an occupancy detecting component. The first infrared sensor may connect to the temperature detecting component through a first temperature signal path and the occupancy detecting component through a first occupancy signal path. The second infrared sensor may connect to the temperature detecting component through a second temperature signal path and the occupancy detecting component through a second occupancy signal path. The temperature detecting component may determine a temperature measurement by calculating an average of a value received from the first temperature signal path and a value received from the second temperature signal path. The occupancy detecting component may determine an occupancy measurement by calculating a difference of the value received from the first occupancy signal path and the value received from the second occupancy signal path.

Abstract: An automatic water faucet device 1 includes: an electrolysis tank 37 that electrolyzes water to generate electrolyzed water; a second water discharge part 13 for discharging the electrolyzed water, a second flow path 18 that extends from the electrolysis tank 37 to the second water discharge part 13; a second solenoid valve 28 that switches between supply and blocking of normal water with respect to the electrolysis tank 37, and a controller 40 that controls the electrolysis tank 37 and the second solenoid valve 28. The controller 40 energizes the electrolysis tank 37 to discharge the electrolyzed water and thereafter stops the energization of the electrolysis tank 37 and maintains an open state of the second solenoid valve 28, to stop the supply of the electrolyzed water to the second flow path 18 and to supply normal water to the second flow path 18.

Abstract: An automatic water faucet device 1 for automatically discharging water when an object to be detected is detected has: a sensor 14 that detects the object; a first water discharge part 12 that performs foamy water discharge; a second water discharge part 13 that performs spray water discharge; and a controller 40 that performs control for switching between the foamy water discharge from the first water discharge part 12 and the spray water discharge from the second water discharge part 13, wherein the controller 40 performs the foamy water discharge from the first water discharge part 12 while the sensor 14 detects the object, and when the sensor 14 no longer detects the object, the controller 40 stops this foamy water discharge, and thereafter performs spray water discharge from the second water discharge part 13 for a predetermined period.

Abstract: A downhole sampling tool is operated to obtain formation fluid from a subterranean formation, which then flows through a flowline of the downhole sampling tool. Real-time density and optical density sensors of the downhole sampling tool are co-located proximate the flowline. Contamination of the formation fluid in the flowline is then determined based, at least in part, on the real-time density and optical density measurements obtained utilizing the co-located sensors.

Abstract: An imaging sensor device is configured to illuminate a viewing field using an array of focused light spots spaced across the viewing field rather than uniformly illuminating the viewing field, thereby reducing the amount of illumination energy required to produce a given intensity of light reflected from the spots. In some embodiments, the imaging sensor device can project an array of focused light spots at two different intensities or brightness levels, such that high intensity and low intensity light spots are interlaced across the viewing field. This ensures that both relatively dark and relatively bright or reflective objects can be reliably detected within the viewing field. The intensities of the light spots can be modulated based on measured conditions of the viewing field, including but not limited to the measured ambient light or a determined dynamic range of reflectivity of objects within the viewing field.

Abstract: The present disclosure introduces a downhole tool conveyable within a tubular within a wellbore extending into a subterranean formation. The downhole tool includes a body and a member having a first end and a second end, wherein the first end is rotatably coupled to the body. A spectrometry sensor is disposed proximate the second end of the member. Embodiments also include a fluid separating component shaped such that a heavier fluid from the fluid flowing along the downhole tool is drawn away from the spectrometry window to reduce window contamination from fluid droplets, particles, and/or liquids.

Abstract: Techniques and apparatus are provided for downhole sensing using optical couplers in a downhole splitter assembly to split interrogating light signals into multiple optical sensing branches. Each optical branch may then be coupled to an optical sensor (e.g., a pass-through or an optical single-ended transducer (OSET)) or to another optical coupler for additional branching. The sensors may be pressure/temperature (P/T) type transducers. Some systems may exclusively use OSETs as the optical sensors. In this manner, if one of the OSETs is damaged, it does not affect light traveling to any of the other sensors, and sensing information from remaining sensors is still returned.

Abstract: A testing system for performing image based direct numerical simulation to characterize petrophysical properties of a rock sample under the simulated deformation condition, for example as representative of subsurface conditions. A digital image volume corresponding to x-ray tomographic images of a rock sample is segmented into its significant elastic phases, such as pore space, clay fraction, grain contacts and mineral type, and overlaid with an unstructured finite element mesh. A simulated deformation is applied to the segmented image volume, and the resulting deformed unstructured mesh is numerically analyzed, for example by way of direct numerical simulation, to determine the desired petrophysical properties.

Abstract: A seismic acquisition system includes a distributed optical sensor (having an optical fiber) and an interrogation subsystem configured to generate a light signal to emit into the optical fiber. The interrogation subsystem receives, from the distributed optical sensor, backscattered light responsive to the emitted light signal, wherein the backscattered light is affected by one or both of seismic signals reflected from a subterranean structure and noise. Output data corresponding to the backscattered light is provided to a processing subsystem to determine a characteristic of the subterranean structure.
