A method for establishing a filtering engine for generating an ordered list of one or more media items selected from a library of media items. The method can be used by a station or stations within a network to classify the signal as non-cooperative or a target signal. Said transmitterreceiver arrangement further comprises an antenna arrangement configured to emit a transmitter signal, and to receive an incident signal, a receiver configured to receive a receiver signal, and an analog isolator connected to said antenna arrangement, said transmitter, and said receiver. First and second initiators are coupled to the switch. In some implementations, a widget workflow method includes: launching a widget at a first device; and updating the widget with content created at a second device.
