A belt assembly, particularly for driving camshafts of an internal combustion engine, includes a driving gear, at least one driven gear, a belt, and a first and a second tensioner blade that are joined to one another for transmitting a defined force and motion. The barrel assembly also has a guide member which is a protrusion that extends horizontally outward from the barrel assembly. The antenna sharing unit, also known as the \u201ccoupler\u201d, includes a tower mounted amplifier simulator. The tachometer reading unit is configured to update the register in response to receiving a new value of the maximum stretching duration.
