The present invention provides a method for joining an RE123 oxide superconductor matrix obtained by a melt process by the use of a solder material. A controller receives frames of video data and generates trajectory data for a movement of a hand in the video data. The latching circuits include at least one pre-charge transistor and at least one output terminal discharge transistor. Typically the deposition steps are carried out in the absence of oxygen. A circuit connected to the sensor and the valve such that the circuit triggers the valve to shut off fuel to the burner in response to a sensed temperature by the sensor.
