Abstract: A system and a method for multi-gas sensing using dielectric excitation of a single sensing material at multiple operating temperatures. By measuring dielectric excitation responses of the gas sensing material, enhanced multi-gas differentiation and differentiation can be achieved using fewer operating temperatures than would be used by the same MOS gas sensing material configured to perform multi-gas differentiation based on resistance responses alone. The disclosed gas sensors and gas sensing techniques enable improved response linearity, improved dynamic range, and reduced computational resource consumption for multi-gas quantitation relative to traditional resistance-based gas sensing methods. Present embodiments unexpectedly demonstrate MOS-based gas sensors that can differentiate between different gases using responses collected using at least two different operating temperatures, wherein this differentiation is superior in the differentiation between different gases and in baseline stability, as compared to the resistance response of the same gas sensing material at more than two operating temperatures.

Abstract: A sensor system includes a sensing element having a section of a layer assembly deposited onto a substrate. The layer assembly includes plural layers of different materials. The section of the layer assembly is configured to be etched to form plural individual pillars of the plural layers of the different materials. The individual pillars are configured to be in contact with a fluid to sense one or more analyte fluid components within the fluid. The sensing element is configured to generate a sensor signal responsive to the individual pillars being in contact with the fluid. The sensor system includes one or more processors configured to receive the sensor signal from the sensing element. The one or more processors may identify the one or more analyte fluid components within the fluid and an amount of each of the analyte fluid components within the fluid based on the sensor signal.

Abstract: A sensor system includes a sensing element that includes a sensing material and electrodes configured to apply a first electrical stimuli to the sensing material at an electrical excitation frequency, a modifier assembly including one or more circuits configured to change an electrical impedance of the sensing element, and one or more processors configured to control the modifier assembly. Responsive to exposure of gas to the sensing element, the one or more processors change a linearity of a first electrical signal received from the sensing element by changing the electrical impedance of the sensing element and applying a second electrical stimuli to the sensing material at the electrical excitation frequency.

Abstract: An inspection apparatus includes a communication unit including a first transmitter and a second transmitter. The communication unit is coupled to an on-board computing device including at least one processor coupled to a memory device. The processor is configured to obtain a position of the inspection apparatus, unprocessed image data, and fluid concentration data for at least one fluid. The processor geotags the data with the position of the inspection apparatus and transmits the data to a remote processing device. The geotagged image data is transferred using the first transmitter and the geotagged fluid concentration data is transmitted using the second transmitter.

Abstract: A monolithic gas-sensing chip assembly for sensing a gas analyte includes a sensing material to detect the gas analyte, a sensing system including a resistor-capacitor electrical circuit, and a heating element. A sensing circuit measures an electrical response of the sensing system to an alternating electrical current applied to the sensing system at (a) one or more different frequencies, or (b) one or more different resistor-capacitor configurations of the system. One or more processors control a low detection range of the system to the gas, a high detection range of the system to the gas, a linearity of a response of the system to the gas, a dynamic range of measurements of the gas by the system, a rejection of interfering gas analytes by the system, a correction for aging or poisoning of the system, or a rejection of ambient interferences that may affect the electrical response of the system.

Abstract: A sensor system includes an electrical circuit having plural leads coupled with one or more sensing regions. The sensing regions include gaps having sensing materials that detect an analyte of interest. The gaps close responsive to the sensing material corresponding to the gaps detecting the analyte of interest. One or more processors communicatively coupled with the electrical circuit receive electrical signals from the electrical circuit indicative of the gaps closing responsive to the sensing material of the corresponding gaps detecting the analyte of interest. The electrical circuit is in a closed position in the presence of the analyte of interest. The sensor system is configured to consume an increased amount of power when the electrical circuit is in the closed position relative to the electrical circuit in an open position responsive to the one or more of the gaps closing. A responsive action is determined based on the electrical signals.

Abstract: A system includes a resonant sensor in contact with oil within a gearbox of a rotor system, such as a wind turbine, and one or more processors. The sensor includes electrodes and a sensing circuit that generates electrical stimuli having frequencies applied to the oil at different times during a life of the gearbox. The processors receive electrical signals from the resonant sensor representative of impedance responses of the oil to the electrical stimuli. The processors analyze the impedance responses and determine a concentration of a polar analyte in the oil at different times. The processors calculate a degradation value for the gearbox based on the concentration of the polar analyte. Responsive to the degradation value exceeding a designated threshold, the processors at least one of schedule maintenance for the rotor system, provide an alert to schedule maintenance, or prohibit operation of the rotor system until maintenance is performed.
