A treatment for mounting on a vertical structure such as a wall, the treatment comprising a valance having a continuous insertion means and a valance rod having a central axis. A laser device is provided with a plurality of these laser modules. The sync points provide a unique identifier field and a context to the data that will follow it. At least a thermoelectric generator element is disposed onto a top surface of the base such that a high temperature surface of the thermoelectric generator element is in thermal contact with the top surface of the base. By normalizing sensor performance, common configuration data can be used to setup a given proximity sensor without having to take into account specific performance variations of that sensor.
