Принадлежит: LANDMARC ENVIRONMENTAL SYSTEMS LLC

A methane monitoring system including a filter, a flow restrictor and a methane level detector is disclosed. The sensor system draws gas from a piping system through a sample line into the filter. The filter removes moisture vapor from the gas, with the remaining gas passing into a flow meter. The flow meter regulates the gas pressure for the gas output to a sensing chamber containing the methane meter. The methane meter operates to sample the methane level in the gas and provides an electrical signal which can be output to a recording device such as a flash memory card or to real time remote reporting via direct connection or a wireless signal such as a cell phone, radio or satellite telecom system. Landfill gas which is introduced into the sensing chamber is then exhausted through vent slots in the housing.

A method and test devices are used for field calibration of gas detectors. Brand new gas detectors are used as measurement standards in field calibration. The brand new gas detectors are in this case either employed directly as working standards, in which case the regular calibration by a reference standard is dispensed with, since the brand new gas detectors are always deemed to be sufficiently accurate. Alternatively, the brand new gas detectors are employed directly, namely as sufficiently accurately calibrated reference standards for the reference gas sensors acting as working standards and incorporated into the test device. In both cases the measured values of the gas sensors in the gas detectors to be calibrated are fed back to a sufficiently calibrated system, namely either directly to at least one brand new gas detector as a working standard or else to a reference sensor of a calibrated test device.

The relaxation oscillator circuit may include a capacitance element that defines a response-pulse frequency of the wireless sensor. The capacitance element may include an interdigitated capacitor coated with a detection layer of a functional material having a dielectric constant that defines the dielectric constant of the interdigitated capacitor. This dielectric constant changes when the functional material is exposed to the analyte, thereby changing the response-pulse frequency of the relaxation oscillator circuit to an analyte-exposure frequency indicative of the exposure of the functional material to the analyte.

In exemplary implementations of this invention, an electronic olfactor determines whether a scent being tested matches the scent of a positive control. The electronic olfactor can perform this scent matching even in a changing olfactory environment, and even if the positive control scent is a combination of hundreds or thousands of different odorants. No prior training is needed, and no attempt is made to identify a single odorant that is unambiguously responsible for a scent. Instead, a computer compares the total scent pattern of a positive control sample with the total scent pattern of a test sample, across a sweep of many permutations of electrical inputs to scent sensors, to try to find any condition under which the total scent patterns do not match. If such a condition cannot be found, then the computer declares a match between the test and target scents. 1.

Methods and apparatuses, including computer program products, are described for measuring greenhouse gas. A calibration device receives a first sample of atmospheric gas from a first port exposed to the earth's atmosphere. The calibration device receives a second sample of atmospheric gas from a second port exposed to the earth's atmosphere. The calibration device routes the first sample and the second sample to a measurement device for greenhouse gas analysis. The measurement device determines a characteristic of a greenhouse gas present in at least one of the first sample and the second sample. The measurement device transmits data associated with the determined characteristic of the greenhouse gas to a computing device for determining sinks and sources of the gas.
