Microwave antenna transmission device having a stripline to waveguide transition via a slot coupling
InactiveUS6081241AImprove efficiencySmall demand on spaceOne-port networksCoupling devicesLeveling effectElectrical conductor
A device for the power transmission of microwaves between a strip-line and a number of parallel cavity waveguides arranged in a group antenna. The strip-line includes H-shaped slots. These slots are centered with respect to a central conductor. Opposite each of the slots, a corresponding slot is arranged through the wall of the cavity waveguide. Electrically conducting seals are arranged to follow immediately outside the contours of the slots. The strip-line is fixedly fastened to the seals and the ridge waveguide, whereby good electrical coupling is achieved. Simultaneously, small cavities are formed between the slots. These cavities have a leveling effect such that the demands on mechanical precision is appreciably lowered, such that the tolerance to placement of the slots opposite to each other is increased substantially as compared to the case of the waveguides directly abutting the strip-line.

Minimalist approach to roadway electrification
InactiveUS20130018766A1Lower potentialImprove operationRailway vehiclesBilling/invoicingElectricityElectricity meter
Method of commerce and system components that enable the sale of electricity on-request to independent vehicle operators for propulsion. Electricity could be delivered by conventional roadway overhead electric line components (see FIG. 2). Vehicles would be equipped with a computer-like component that contains an electricity meter, flow switches, and wireless communications capabilities (see FIG. 14) to communicate with an operations (12) computer site. Site would have customer credit profiles for approving distribution, wirelessly requested from customer vehicles. Vehicles would be additionally equipped with a robotic collector module (51). If implemented on a highway, the driver would request service while driving in an electrified lane via a user interface and, if approved, the robotic collector module (51) handles engaging electrical contact and disengaging when needed. Customer would be electronically billed for the electricity used. There is a continuous roadside monitoring network for improved safety and vehicle authentication (see FIG. 11, 12).
