  • Patent number: 11598659
    Abstract: Techniques are described herein for displacing liquid away from a signal path of sonic signals in a signal anemometer. A sonic anemometer may include a membrane positioned between a sonic transducer and the open environment. The membrane may be formed of a hydrophobic material that repels the liquid. The membrane may also include a plurality of pores that impede the flow of liquid through the membrane but enables sonic signals to pass through the membrane. The sonic anemometer may also include a reflector that displaces liquid away from the signal path of the sonic anemometer. The reflector may include one or more pores that wick liquid away from the signal path.
    Type: Grant

  • Patent number: 8079757
    Abstract: An apparatus configured to determine water activity and weight of a sample. The apparatus may comprise a chamber configured to at least partially enclose a sample. The apparatus may also comprise a sensor configured to measure water activity of a sample in the chamber. Additionally, the apparatus may comprise a moisture content adjustment device connected to the chamber and configured to change moisture content in the chamber. An isotherm generation module is also disclosed. The isotherm generation module may be configured to receive water activity measurements from a sensor device and weight measurements from a weighing device, the isotherm generation module being configured to generate an isotherm for a sample based on the water activity measurements and the weight measurements.
