  • Patent number: 12344519
    Abstract: A beverage dispensing device comprising a beverage reservoir, a receptacle that receives a beverage container including a beverage and discharges the beverage from the beverage container into the beverage reservoir, a cutting mechanism that opens the beverage container to release the beverage, a cooling system comprising one or more thermoelectric coolers including one or more plate-like surfaces along the flow path wherein the cooling system performs at least one of chilling or warming the beverage that flows over at least part of the plate-like surface. The beverage dispensing device further comprising a pump that transfers the beverage from the beverage reservoir to the cooling system, an aeration component that receives and aerates the beverage from the cooling system, and a discharge nozzle coupled to the aeration component that dispenses the beverage.

  • Publication number: 20250042711
    Abstract: A beverage dispensing system comprising a beverage reservoir, wherein the beverage reservoir comprises a container coupled to a cooling system. The beverage dispensing system further comprising a beverage pump coupled to the beverage reservoir, wherein the beverage pump is configured to pump contents of the beverage reservoir to the cooling system. The beverage dispensing system further comprising a sensor configured to detect whether the beverage reservoir is empty, a cleaning reservoir comprising a container, and a cleaning pump coupled to the cleaning reservoir, wherein the cleaning pump is configured to pump contents of the cleaning reservoir to the beverage reservoir. The beverage dispensing system further comprising an liquid sensor configured to detect whether the beverage reservoir is empty, and a programmable circuit board configured to receive a signal from the liquid sensor and control operation of the beverage pump based on the signal.

  • Patent number: 11274956
    Abstract: The present invention comprises a novel foldable and intrinsically safe planar coiled inductance sensor to measure liquid depths, solids in liquid depths, and two different liquids depths. This invention is used in onsite wastewater management systems (OWTS) to monitor depths of solids, oil, and effluent in a wastewater tank. The inductors are configured to allow for solids, liquids and gases to surround the coils. A number of coils are hung in series from near the OWTS tank lid to at least 18 inches below the output baffle to measure the different materials at different depths in the OWTS tank. The inductance sensors are capable of use with various materials to measure solids, oil, and effluent depths in an OWTS tank.

  • Patent number: 10993147
    Abstract: Systems, devices, and methods for a wireless communication reservation bandwidth allocation manager system that includes a device for requesting an out-of-band Quality of Service request following a a set of Application Programming Interfaces for an RSVP. A provider determines if the requested out-of-band Quality of Service is available, a negotiation with a third party service provider for the requested out-of-band Quality of Service, a reservation for the requestor device from the provider when the out-of-band Quality of Service becomes available, and a termination of the reservation when the requesting device notifies the provider that the requested out-of-band Quality of Service is complete.
