Systems and methods are provided for discharging a voltage bus. This apparatus detects an abnormality of the sensor when the detected temperature is at a first temperature which is higher than an activation temperature of the sensor and the detected admittance is less than a first determining value. The colored image information is notably applied by means of a thermal method and the surface is preferably treated by application of an adhesive coating. The interface may receive the playlist file from the playlist server, the playlist file including locations of stream segments corresponding to the selected playlist. A vacuum bag is applied for the polymerization cycle.
