Abstract: An automotive radar system includes a printed circuit board (PCB) formed from a plurality of layers including a first outer layer, a second outer layer, and a plurality of intermediate layers. A coaxial structure extends from the first outer layer to the second outer layer. A monolithic microwave integrated circuit (MMIC) is mounted to the first outer layer and connected to the coaxial structure. A first waveguide is formed in the second outer layer, and a second waveguide is mounted to the second outer layer over the first waveguide. The coaxial structure forms a direct energy path from the MMIC to the first waveguide.

Abstract: A system for capping the upper opening of a well having an accommodation for a remotely-located control device. More specifically, a well cap system for a water-well having a pipe casing that permits one or more well control apparatus to be located within the well cap. The system is a two-part assembly, comprising a base and hollow cover, both arranged to be supported by the pipe casing. Further, a constant pressure well system utilizing the water-well cap system.
