  • Patent number: 11994462
    Abstract: Multi-spectral methods and systems for the day and night remote sensing (detection, identification, and quantification) of greenhouse gas emission sources from space are provided. The sensor system includes a telescope assembly that passively collects light from an observation area and directs that light through spectral, optical filters and to a sensor array having a plurality of rows and columns of pixels. Different groups of sensor array pixel rows are aligned to receive light that has passed through different optical filters. The filters have passbands corresponding to the reflective and emissive bands of gases of interest, as well as associated reflective and emissive reference bands, and broadband spectral bands. A set of image data frames is obtained as the field of view of the sensor system moves over an observation area and an aggregate image showing locations of detected gas emissions is generated using the collected data.

  • Patent number: 11985442
    Abstract: Bias circuit elements for applying voltages/currents to a photodetector are described. Bias circuit elements described are active devices, e.g. mosfets, directly connected to the photodetector signal point, which inject noise that will be amplified/integrated. Lowering 1/f noise in these bias devices uses multiple parallel mosfets and switching the parallel mosfets gates between a bias activation level signal and a voltage sufficient to drive the mosfet into accumulation Gate switching may be accomplished by at least two partially out of phase clocking signals, with at least one parallel mosfet applying bias while another is in accumulation in continuously switched time periods. Gate switching at a frequency higher than the imaging bandwidth, will have negligible effect on the image signal. During the accumulation phase traps present within the conducting channel of each MOSFET will be depopulated, essentially resetting the MOSFET's 1/f noise, allowing for long integration times while controlling 1/f noise.

  • Patent number: 11977025
    Abstract: Gas sensors are disclosed having an on-board, low-power data processor that uses multivariable gas classification and/or gas quantitation models to perform on-board data processing to resolve two or more gases in a fluid sample. To reduce computational complexity, the gas sensor utilizes low-power-consumption multivariable data analysis algorithms, inputs from available on-board sensors of ambient conditions, inputs representing contextual data, and/or excitation responses of a gas sensing material to select suitable gas classification and/or gas quantitation models. The data processor can then utilize these gas classification and quantitation models, in combination with measured dielectric responses of a gas sensing material of the gas sensor, to determine classifications and/or concentrations of two or more gases in a fluid sample, while consuming substantially less power than would be consumed if a global comprehensive model were used instead.

  • Patent number: 11913879
    Abstract: Disclosed is a sensor and method for detecting one or more gasses in a sample. The sensor includes two sample tube sections, which allow for a larger sample, and correspondingly, more accurate measurement. Having two sample tube sections increases the total length of the sample path. However, placing the sample tube sections in parallel allows for the performance of the sensor to be enhanced, but the footprint of the sensor to remain unchanged. Light pipe material may be used to transport the light between sample tube sections. Further, light pipe material may be used to move the IR lamp away from the first filter tube section, reducing problems in the thermopile by dissipating heat from the IR lamp away from the sample tube section.
