A method for depositing a first material on a substrate includes providing the substrate in a deposition chamber. A rotational L-shaped connector of an antenna section of the antenna is connected to an antenna housing disposed on a main electronic device unit. The processor then generates ECM signals based on the threats and sequentially outputs the ECM signals to a transmitter. A power unit is configured to drive the transparency regulation element to darken the first lens system without substantially darkening at least a portion of the second lens system during a first period, and, during a second period after the first period, to not drive the transparency regulation element to darken the first lens system.
