A method of controlling steering of a vehicle through setting wheel angles of a plurality of modular electronic corner assemblies is provided. The drum provides a flange integral with it and couplable in rotation with a locking disc equipped with teeth engageable with opposing teeth capable of stopping its rotation. Furthermore, the construction features of the serial drive assembly that can be customized are stored in the database with their variation parameters and limitations. The casing is configured so that when the connector is engaged in the main engagement element, the cable forms a loop defining a space between the casing and the cable to hang the device. The apparatus further includes a trap, a filter and a heat exchanger for conducting a desired treatment with respect to the circulated gas, such as removal of particles. The printed circuit board is attached with a LED, and the LED is electrically connected with the contacts.
