A device for coupling microwave signals with arbitrary phase shifts and power split ratios over broadband may comprise a first branch comprising a cascade of first stripline sections connected to one another. One package contains a heating assembly made of a heating element, a flexible power cable ending in an electrical connector, and a power pack that contains a rechargeable battery, a rheostat, and a mating electrical connector. The mapping protocol can be configured to convert packets including the flow ID into packets that conform with a given addressing protocol for routing to the application server. The resulting, sanitized graph can be subsequently used for publishing andor querying purposes. The housing surrounding the rotor is constructed as a composite part in which a first thin-walled layer defines the inner configuration of the housing, and at least one second layer provides structural stability to the housing. The optical system is configured to discriminate between headlamps and tail lamps, and focus the light rays from the headlamps and tail lamps on different portions of a pixel sensor array.
