Abstract: Electrode vibration detection modules (EVDM) and methods of detecting vibration of an electrode of an electric arc furnace (EAF) using an EVDM are provided, in which the EVDM receives and/or ascertains waveform signals corresponding to voltage values and current values associated with an electrode voltage measured between the electrode and the bottom of the EAF shell (electrode voltage) and the electrical current passing through the electrode and is configured to identify conditions for electrode vibration based, at least in part, on the waveform signals and to trigger an alarm and/or modify the operation of the EAF by adjusting the location of the electrode in the EAF.

Abstract: A ball tossing apparatus includes a support frame and a plurality of launch devices fixed to the support frame and arranged in a two-dimensional array. The launch devices include cylinders having a spring fixed therein, with a ball carrier fixed to the spring. The balls are retained in a loaded position (springs compressed) and then upon activation of the launch devices are launched vertically into the air to the sports player. In another embodiment, the launch devices include a rotating lever which is acted on by a biasing member to launch the ball vertically from the cylinder. A method for launching the balls includes the steps of loading the balls into a two dimensional array, and then launching the balls according to a launch sequence. An electronic control system for use with the ball tossing apparatus includes a launch module for launching the loaded balls in the plurality of launch devices according to a launch sequence.
