  • Publication number: 20040139799
    Abstract: A sensor for determining flow rate of a fluid includes a thermistor inserted into a volume through which the fluid flows. The thermistor cycles between its zero-power mode and its self-heated mode. In the zero-power mode, the thermistor is used to determine the ambient temperature of the fluid. In the self-heated mode, the thermistor is used to determine the amount of heat removed by the fluid. The ambient temperature of the fluid, the amount of heat removed by the fluid, and the thermal properties of the fluid are then utilized to determine the flow rate of the fluid.

  • Publication number: 20040015263
    Abstract: A network topology for communication within and between food service equipment items generally comprises one or more food service equipment items, each having a controller and at least one functional subsystem configured as a slave to the controller, and a master interface and a bus slave interface associated with each controller. Each master interface is adapted for electrical communication over an intra-equipment communication channel with a slave interface associated with the functional subsystem. Each bus slave interface is adapted for communication, external to the food service equipment item, over an inter-equipment communication channel. Each bus slave interface is substantially electrically identical to each slave interface.

  • Patent number: 6650962
    Abstract: A beverage dispenser includes an electronic control system for controlling beverage dispenser components. The beverage dispenser components include at least a user interface, a dispensing valve, and a valve interface for regulating the delivery of a beverage from the dispensing valve. The electronic control system includes a microcontroller for monitoring the user interface and for activating the valve interface responsive to user input, thereby regulating the delivery of a beverage from the dispensing valve. The electronic control system further includes a program memory with firmware configured in a state machine system architecture for controlling the microcontroller. The state machine system architecture supports either a non-preemptive or a preemptive multitasking real time operating system. The firmware includes supervisory control firmware, dispenser tasks firmware, and low level drivers firmware.

  • Publication number: 20030192912
    Abstract: A beverage dispenser includes a customer interface and a logic unit for controlling beverage dispenser operations. The customer interface includes a sensor linked with the logic unit. Specifically, the sensor receives an input and outputs a corresponding command signal. The logic unit receives the corresponding command signal from the sensor and thus controls beverage dispenser operations.

  • Patent number: 6568565
    Abstract: A method and apparatus for dispensing a product includes a support housing, a disposable or non-disposable pump, a disposable product package connectable to the pump, a pump driver connectable to the pump, and a dispensing station on the support housing. The dispensing station supports the pump driver and is adapted to receive the pump and disposable product package. The disposable product package and the pump driver connect to the pump. The pump driver operates the pump to draw product from the disposable product package. When the disposable product package is empty, the disposable product package and the pump if disposable are removed from the dispensing station and disposed.
