An example apparatus for providing an interactive inspection map of an inspection surface may include an inspection visualization circuit to provide an inspection map to a user device in response to inspection data provided by a plurality of sensors operationally coupled to an inspection robot traversing the inspection surface, wherein the inspection map corresponds to at least a portion of the inspection surface. The apparatus may further include a user interaction circuit to interpret a user focus value from the user device, and an action request circuit to determine an action in response to the user focus value.

The inspection visualization circuit may further update the inspection map in response to the determined action.

A method for non-intrusive pipeline testing involves constructing the pipeline at a construction location that is above ground, affixing an optical fiber along a surface of a length of the pipeline that is at the construction location, measuring dynamic strain experienced by the length of the pipeline by performing optical interferometry using the optical fiber, and moving the length of the pipeline from the construction location to a different installation location. The optical fiber includes at least one pair of fiber Bragg gratings (FBGs) tuned to reflect substantially identical wavelengths with a segment of the optical fiber extending between the FBGs.

Systems and methods are disclosed to analyze sediment and sedimentary rock properties. Example systems and methods transform data representing physical particles and burial histories into a three-dimensional representation of solids and pores in sediments and sedimentary rocks by analyzing effects of deposition, grain rearrangement, compaction, and chemical reactions. Resulting output may include three-dimensional representations which may be the basis of physical objects or media for laboratory tests. In an example, output may provide a basis for evaluating present-day properties for areas where sample material is unavailable, reconstructing properties for times in the geologic past, and forecasting the effects of engineering and industrial activities on properties.

The present application describes embodiments of a radio-frequency identification (RFID) sensor based on a combinationof a surface acoustic wave (SAW) transducer and two-dimensional electron gas (2DEG) or two-dimensional hole gas (2DHG) conducting structure, and its use in chemical detection and (bio)molecular diagnostics. The SAW RFID sensor chip contains apiezoelectric substrate, on which a multilayer heterojunction structure is deposited. The heterojunction structure comprises atleast two layers, a buffer layer and a barrier layer, wherein both layers are grown from III-V single-crystalline or polycrystallinesemiconductor materials, such as GaN/AlGaN. Interdigitated transducers (IDTs) transducing SAWs are installed on top of thebarrier layer. A 2DEG or 2DHG conducting channel is formed at the interface between the buffer and barrier layers and provideselectron or hole current in the system between the non-ohmic (capacitively-coupled) source and drain contacts connected to the formed channel.
