  • Patent number: 10782235
    Abstract: Chemical sensors today are deployed in massive volumes across multiple industries and yet at the same time they are subject to substantial research and development effort to establish new, faster, lower cost, more accurate, more sensitive chemical sensors. Such sensors and sensor arrays are being exploited across chemistry, biology, clinical biology, environmental science in civilian and military markets. Amongst the many sensor methodologies are xerogel substrates with two moieties, a receptor for molecular recognition of the analyte and a luminophore for signaling the recognition event. In order to fulfill the requirements for low cost there is a requirement for electronic excitation/read circuits that can support architectures with optical source—N sensors—X filters—M detectors, where M?N and X=N|M.

Laser ablation is used in the method for detaching particles from the target, and the particle flux vaporised by laser pulses is directed to the base material to be coated, to which the material is attached. The so-called roll-to-roll principle can be used in the method, in which the base material to be coated is directed from one roll to a second roll, and the coating occurs in the area between these rolls. In addition, rotating mirrors and a telecentric lens can be used for aligning the laser pulses as a rectilinear pulse front before guiding onto the target material.

The method includes selecting the user characteristic spectral line to be measured; based on the characteristic spectral line of the alkali metal, constructing a fitting model between radiation strength of the characteristic spectral line of the alkali metal in the burning flame and the gaseous alkali metal concentration and flame temperature; calibrating the spectrograph under absolute radiation strength; measuring a flame object corresponding to an alkali metal concentration by the calibrated spectrograph to obtain the radiation strength and flame temperature of the characteristic spectral line of the alkali metal. The detection method can detect the concentration of the gaseous alkali metal in the burning flame of the detection furnace quickly and accurately as well as detect the content of the base metals, involves simple devices, low cost, and is suitable for field measurement.

  • Patent number: 9612361
    Abstract: An example method includes performing validation testing on a tool using a plurality of reference fluids, the tool having a calibrated optical sensor installed therein that includes one or more optical elements. One or more tool sensor responses from the calibrated optical sensor may be obtained and pre-processed, and the one or more tool sensor responses may be compared with calibrated optical sensor responses derived from the calibrated optical sensor during calibration and thereby detecting one or more optical sensor anomalies. The one or more optical sensor anomalies may be evaluated through performance analysis with one or more candidate models, and an alternative candidate model may be selected to mitigate the one or more optical sensor anomalies. One or more remedial options may be pursued when the alternative candidate model fails to mitigate the one or more optical sensor anomalies.

  • Patent number: 9577510
    Abstract: An inverter device includes an inverter circuit, which has switching elements in a bridge connection, a capacitor, which is connected in parallel to the input side of the inverter circuit, a control device, which controls the inverter circuit, a temperature detector, which detects the temperature of the capacitor, a degree-of-deterioration determiner, which determines the degree of deterioration of the capacitor, and a warm-up controller. When the temperature of the capacitor detected by the temperature detector is lower than a prescribed temperature, the warm-up controller controls the switching elements of the inverter circuit to supply a direct current set based on the degree of deterioration and the temperature of the capacitor to the coil of an electric motor connected to the output side of the inverter circuit.
