Abstract: Induction heating power supplies, data collection systems, and induction heating systems to communicate over an induction heating cable are disclosed. An example induction heating power supply includes a power conversion circuit configured to: convert input power into induction heating power and transmit the induction heating power via an induction heating cable, and at least one of a receiver circuit coupled to the induction heating cable and configured to receive data via the induction heating cable or a transmitter circuit coupled to the induction heating cable and configured to transmit data via the induction heating cable.

Abstract: A heating system includes a power source connected to a heater to heat a workpiece via the heater and a controller. The controller is configured to receive the first temperature measurement signal, the first temperature measurement signal corresponding to a first temperature of the workpiece. The controller is to turn on the power source to activate the heater to heat the workpiece, receive the second temperature measurement signal in response to heating the workpiece, the second temperature measurement signal corresponding to a second temperature of the workpiece. The controller calculates a change in temperature of the workpiece based on the first and second temperatures, and determines a physical characteristic of the workpiece based on the change in temperature.

Abstract: Induction heating accessories are disclosed. An example induction heating accessory comprises: a coupling circuit configured to be electromagnetically coupled to a cable carrying induction heating current; a power extraction circuit configured to extract power from the induction heating current via the coupling circuit; and circuitry configured to generate an output indicative of the induction heating current flowing through the cable based on receiving power via the induction coil.
