To provide a tire vulcanizer capable of solving problems of an electrical heating platen, which relate to the deformation at the time of tire vulcanization and to the replacement of the platen. The first light emitter is arranged relative to second light emitter so as to generate a zone that is unlit by the first lighting device between the first light strip and the second light strip. The group of communications devices may communicate machine type communications for a particular application, for example in a vehicle, to report parameters that can be served by a separate communications device that reports periodically on the parameters detected by an associated sensor. In the event it is determined that the data mover should be asked to permit the second volume to be removed from the storage device so that the first volume can be mounted thereon, the data mover is prompted to provide an indication that the second volume may be dismounted from the storage device. Various embodiments are disclosed.
