The present embodiments provide apparatuses and methods for use in receiving radio frequency signals. Said integrated circuit further comprises at least one communication managing unit for managing the communication between said plurality of modules, wherein said communication managing unit receives a request for a communication between at least two of said modules and dynamically selects one of said plurality of communication services as basis for the requested communication between said modules. The frequency of radar signals from the transmitter is adjusted according to a velocity of the aircraft calculated using the error in ground speed estimate or using the error in ground speed estimate. The drive signal source units supply drive signals to a gate electrode G and a source electrode S respectively in each of the pixels constituting the TFT substrate.
