A fluid ejector head, includes a fluid definition layer defining a chamber, the fluid definition layer having a substantially planar passivation surface. One or both coupled arm outputs of the directive coupling structure are connected to the inputs of a broadband RF receiver. Each left and right part is assembled by connecting front upright posts, back upright posts, upper beams, lower beams and brace rods. The PCRF creates second PCC rules based on the request, and installs them at the PCEF by replacing the first PCC rules by the second PCC rules. The multiply-accumulate MMW transceiver recovers the first and second data elements from the MMW data signal and recovers a command corresponding to the function from the MMW instruction signal. Switch selection is also performed in response in relationships of the AC main voltage components expressed in stationary dq coordinates.
