  • Patent number: 10598582
    Abstract: An orthogonal superposition rotational rheometer that applies a rotational torque and an orthogonal axial oscillatory stress to a fluid. The rheometer uses a cylindrical bob in a double wall cup to apply shear rotational and axial forces to the fluid. Openings in the top section of the cylindrical bob reduce surface tension effects on the force measurement. Fluid pumping effects at the bottom of the rheometer's double wall cup are minimized by openings in the inner wall of the double wall cup that allow fluid to be displaced when the bob moves downwards.

  • Patent number: 10585058
    Abstract: An illustrative humidity sensor may include a substrate having a source and a drain, wherein the drain is laterally spaced from the source. A gate stack is provided in the space between the source and the drain to form a transistor. The gate stack may include a gate insulator situated on the substrate to form a gate insulator/substrate interface. The gate stack may further include a barrier layer above the gate insulator. The barrier layer may be configured to act as a barrier to mobile charge, humidity and/or other contaminates, and may help prevent such contaminates from reaching the gate insulator/substrate interface. The gate stack may further include a humidity sensing layer above the barrier layer. The humidity sensing layer, when exposed to humidity, may modulate the conduction channel in the substrate under the gate insulator and between the source and the drain. In some cases, the humidity level may be determined by monitoring the current flowing between the source and drain.

  • Patent number: 10571458
    Abstract: A method and a device for determining the emission of greenhouse gas, in particular methane, by ruminants, in particular dairy animals includes counting eructations (“belches”) of the animal. This is done by measuring a signal linked to the eructations, for example sound with a microphone. Given that the methane content of an eructation of this type is more or less constant, the total methane emission can be derived therefrom by counting.
