  • Patent number: 11940317
    Abstract: A filter device and methods of use thereof are provided. The filter device may include a pitcher for removably engaging with a base in fluid communication with a fluid source. The pitcher may include a magnetic float assembly, and the base may include a sensor, e.g., a Reed switch, for detecting when a magnetic float of the magnetic float assembly is within a detectable range of the sensor. Upon detection of the magnetic float within the detectable range by the sensor, a controller of the filter device may instruct a pump to pump fluid from the fluid source, through a filtration system of the filter device, and into the pitcher. When the pitcher is full of fluid, the magnetic float will be out of the detectable range of the sensor, such that fluid will stop being transferred from the fluid source to the pitcher.

  • Patent number: 11874152
    Abstract: A technique facilitates fluid flow measurement by providing a meter able to accurately monitor fluid flow of a liquid even if gas is present in the liquid. The meter may comprise a tubing with an internal flow passage and a wedge or other restriction extending into the internal flow passage. A first port is located upstream of the restriction and a second port is located downstream of the restriction to enable monitoring of a differential pressure across the restriction. The differential pressure can be used to determine the desired flow parameter, e.g. volumetric flow. The system facilitates separation of gas from the liquid and utilizes a gas bypass. The gas bypass routes the separated gas past the restriction, e.g. wedge, before directing the gas back into the fluid flow path.

  • Patent number: 11858276
    Abstract: An implementation of the present teachings includes a resistor structure for measuring a level of a print material such as a liquid metal print material within a reservoir of a printer such as a magnetohydrodynamic printer. The resistor structure includes a first electrode and a second electrode that are physically and electrically separated from each other. When positioned within the reservoir, the liquid metal physically contacts the first electrode and the second electrode. An electrical resistance between the first and second electrodes changes depending on the level of the print material within the reservoir. As the level of the print material decreases, the electrical resistance between the first electrode and the second electrode increases. The electrical resistance can be measured and used to determine a level of the print material within the reservoir.
