Abstract: Apparatuses, systems, and/or methods for providing an induction heating system are disclosed. The induction heating system includes an induction power supply and an induction heating tool configured to receive induction-type power from the induction power supply through one or more ports. The ports may be part of the induction power supply and/or an associated junction box. The induction heating tool may include a heating coil attached to one or more plugs via one or more cables. The ports of the induction power supply and/or junction box are configured to receive the plugs of the induction heating tool. A communication device may be positioned adjacent the ports. The communication device may be configured to read data from one or more memory devices of the induction heating tool (e.g., in/on the plugs) via close proximity communication.

Abstract: A beverage dispenser for filling a container preferably has a nozzle through which the beverage is discharged and a pivoting lever located underneath the nozzle that detects the placement of a container so as to regulate the actuation of the dispenser. A conductive probe is in line with the discharged beverage stream, the lever also being conductive. A signal generator generates a varying-over-time signal that is applied to the probe or lever. As a result of beverage overflowing the container, the beverage stream establishes a conductive path between the probe and lever. The signal through this conductive path is compared to the signal produced by the signal generator. If the signals are substantially identical for a select period of time, the dispensing system is considered to be in an overflow state, and beverage dispensing is terminated.
