Abstract: A device to determine density includes a housing, a first transducer disposed in the housing at a first position, and a second transducer disposed in the housing at a second position. The second transducer is located a distance from the first transducer. The device also includes a controller that reads a first output from the first transducer, and reads a second output from the second transducer. The controller determines a density of a liquid based on the first output, the second output, and the distance.

Abstract: A device for detecting and characterizing anomalies in a water continuum is provided. The device is configured to receive measurements of physical quantities on the basis of sensors situated in the water continuum. The measurements are thereafter transformed, and a detection of anomalies is performed by a detector of anomalies which is trained with transformed values arising from the same sensors. In parallel with the detection, predefined rules make it possible to characterize a possible anomaly. Thus, an anomaly detection can be optimized for a water continuum in particular, whilst characterization with predefined rules allows the device to be operational without each anomaly having needed to be detected in this water continuum in particular.

Abstract: An elution apparatus and a detection apparatus are described. The elution apparatus includes: a sample trap for trapping a sample; and one or more pumps and/or valves to move a liquid eluent and a liquid eluate, wherein the eluate includes an extracted portion of the sample that is extracted by the eluent. The detection apparatus includes: a capillary having a low-voltage (LV) end portion to receive a sample; and a conductivity detector coupled to a high-voltage (HV) end portion of the capillary to generate signals based on conductivity of a monitored portion of the capillary in the HV end portion, wherein the conductivity detector is electrically isolated from the LV end portion.

Abstract: The present invention relates to a phase separation sensor which can easily change its direction due to its flexible feature without using a corner connector even at a position limited in space or at a narrow space, and can separate and sense water and chemical solution so as to be easily used in outdoor environment exposed to rain, snow, hail or others. The phase separation sensor includes: a detection part (100) having a pair of detection lines (110, 120) spaced apart from each other in a width direction to be arranged side by side; and an insulation part (200) having insulation films (210, 220), which have detection holes (210a, 220a) formed at equal intervals in a longitudinal direction to be opposed to the detection part (100) and adhesive layers (211, 221) formed at areas of the insulation films (210, 220), which touch the detection lines (110, 120).

Abstract: Disclosed herein are example embodiments of a transformative sensor apparatus that is capable of detecting and quantifying the presence of a substance of interest such as a specified bacteria within a sample via changes in impedance exhibited by a detection electrode array. In an example embodiment, sensitivity is improved by including a focusing electrode array in a rampdown channel to focus a concentration of the substance of interest into a detection region. The focusing electrodes include an opposing pair of electrodes in a rampdown orientation. The focusing electrode may also include tilted thin film finger electrodes extending from the rampdown electrodes. In another example embodiment, trapping electrodes are positioned to trap a concentration of the substance of interest onto the detection electrode array.

Abstract: The present invention is one that makes it possible to continuously measure the resistivity of a liquid sample with accuracy as well as preventing the deterioration of the liquid sample associated with measurement, such as change in quality, and relates to a resistivity-measuring circuit C that measures the resistivity in order to sense the deterioration of the liquid sample. The resistivity-measuring circuit C is one that calculates the resistivity of the liquid sample by detecting voltage generated between an outer electrode and an inner electrode, and between the outer electrode and the inner electrode, applies square wave AC voltage having an amplitude of 1 V to 42 V and a frequency of 0.5 Hz to 30 Hz.
