  • Patent number: 11353388
    Abstract: A TDR matrix suction sensor measures the matrix suction exhibited by a porous medium surrounding the sensor. The sensor is constructed from a TDR matrix suction sensor probe, which includes two or more elongated conductors and a jacket that encases the conductors. The jacket is made of a hydrophilic, non-conductive, porous (HN-CP) material. In operation, a pulse delay time is computed for an electrical pulse injected into the proximal end of the conductors and reflected when reaching their distal ends. The pulse delay time and a delay-to-matrix suction profile of the HN-CP jacket material are used to compute the matrix suction exhibited by the probe jackets. An indicator of the current value of the matrix suction exhibited by the porous medium is then established based on the matrix suction computed for the HN-CP jackets.

  • Patent number: 11340146
    Abstract: A gas monitoring and control system including a gas sampling chamber, sampling inlet and outlet valves, a pump and a controller. Sensors are disposed within the interior chamber that sense characteristics of a gas from a gas source and generate representative signals. The sampling inlet and outlet valves i) allow the gas into the gas sampling chamber while operating in a gas sampling state, and ii) allow ambient air into the gas sampling chamber while operating in a purge state. The pump i) causes the gas to flow through the gas sampling chamber while operating in the gas sampling state or ii) causes ambient air to flow through the gas sampling chamber while operating in the purge state. The controller causes the sampling inlet and outlet valves, and the pump to alternate operating in the gas sampling or purge state to selectively expose the sensors to the gas.

  • Patent number: 11278215
    Abstract: An acoustic system can track gas emissions by exploiting the nostril-accessible nasal pathways of an animal. Actuators and microphones used in the apparatus can be similar to those currently found in cell phones, which in turn make the acoustic apparatus small and rugged. The nostril geometry can be mapped using sound waves, similar to the mapping done by an acoustic rhinometer. Where acoustic rhinometers assume a constant speed of sound to measure changes in geometry, acoustic approaches as disclosed herein can assume constant geometry to measure changes in the speed of sound. Approaches disclosed here are particularly useful with any gas, such as (for example) methane, hydrogen, helium, etc. that has a speed of sound higher than other typical gaseous components of exhaled air, such as nitrogen, carbon-dioxide, oxygen, etc.
