Abstract: A system for dispensing fluid. The system includes a fluid cartridge having a fluid outlet spout, a carbonated fluid outlet, a still water outlet, and a non-contact drop sensor for detecting a number of drops dispensed from the fluid outlet spout. The fluid outlet spout, the carbonated fluid outlet, and the still water outlet are configured to dispense fluid into a beverage vessel.

Abstract: Systems and methods are provided for predicting failure of an air filter within an HVAC installation. Also provided are methods for calibrating the systems described. The system provided typically includes air filters and vents, and a processor at an application server configured to implement methods described. Each vent may include various sensors, such as a temperature sensor or a sensor for evaluating indoor air quality. The method may receive information about a total volume of air pumped by an HVAC system over time, determine the volumetric quantity of air passing through a particular filter, and compare that quantity of air to a threshold amount representing the lifetime, or some percentage of the lifetime of the filter. Where the system includes multiple vents and multiple filters, the system may implement a model for calculating the volumetric quantity of air associated with each individual filter.

Abstract: A system for carbonating fluid is provided comprising a gas supply and a fluid vessel for carbonating fluid, the fluid vessel having at least one internal surface for obstructing a return path of the gas to an upper surface of the fluid after injection. A retainer retains the fluid vessel relative to the gas supply and a gas injector injects gas from the gas supply into the fluid vessel. During use, the gas injector injects gas below a fluid level within the fluid vessel.

Abstract: A system for dispensing fluid is provided in which a first fluid cartridge and a second fluid cartridge each comprise a first spout at corresponding fluid outlets, and wherein a docking location is provided for docking each of the fluid cartridges such that the first spout is adjacent the second spout. The system may further comprise a drop sensor for detecting a number of drops dispensed from the fluid cartridges at a drop detection location. The docking location may define a specific orientation for any cartridge docked at the docking location, and the cartridges may be wedge shaped and may each taper towards their corresponding spouts. Also provided is a fluid cartridge comprising a cartridge housing, a fluid inlet, a fluid outlet above a fluid fill level, and a syphon for transporting fluid from inside the cartridge to the fluid outlet.
