  • Patent number: 11030423
    Abstract: The present invention enables an analysis device that utilizes light absorption to measure concentrations of target components by means of a simple calculation, and without any complex spectrum calculation processing being required, and analyzes target components that are contained in a sample, and is provided with a light source that emits modulated light whose wavelength is modulated relative to a central wavelength using a predetermined modulation frequency, a photodetector that detects an intensity of sample light obtained when the modulated light is transmitted through the sample, a correlation value calculation unit that calculates correlation values between intensity-related signals that are related to the intensity of the sample light, and predetermined feature signals, and a concentration calculation unit that calculates concentrations of the target components using the correlation values obtained by the correlation value calculation unit.

  • Patent number: 10948472
    Abstract: Undetected emissions may damage devices at a work site and pose a safety hazard to the surrounding environment. A method of control based on predictive emissions detection is disclosed. The method uses sensors coupled to work site equipment to identify devices and regions of a work site that may be affected by adverse conditions. Detection of such emissions may allow the system or operator to shut down or otherwise act on equipment before any harm is done to the device or personnel in the area.

  • Patent number: 10852281
    Abstract: A gas concentration image (i.e., concentration vs. position data) in a cross section through a gas plume is obtained. Such measurements can be obtained by using a 2D array of gas sample inlets, or by moving a 1D array of gas sample inlets through the gas plume. By combining a gas concentration image with ambient flow information through the surface of the gas concentration image, the leak rate (i.e., gas flux) from the leak source can be estimated. Gas samples are simultaneously acquired by filling two or more gas sample storage chambers. This is the default operation mode, which is convenient to regard as recording mode. The other operating mode is a playback mode, where the gas samples in the gas sample storage chamber are sequentially provided to a gas analysis instrument. Gas collection via line pixels can be used to compensate for vertical wind speed variation.

  • Patent number: 10802033
    Abstract: A method is provided for measuring status parameters of a fluid contained in a container (10). The container (10) is configured for single use and has a wall on which a sensor-carrier plate is fixed in a fluid-tight manner. The plate carries sensors (S1-S5) that are in operative contact with the internal chamber of the container (10) and connected for data exchange (14) with an external control unit (16) that receives and processes the measurement data from the sensors (S1-S5). The sensor plate also carries a temporarily inactive duplicate (D1-D5) of at least one of the sensors (S1-S5) that is activated if measurement data of the sensor (S1-S5) is classified as atypical in the context of an integrity or plausibility test carried out by the external control unit (16).
