Abstract: Aspects of the disclosure provide for a system for a power over data line (PoDL) system. The system includes a ground plane that has a cutout. In addition, an alternating current (AC) capacitor pad configured to establish a bidirectional data channel. The AC capacitor pad is positioned in the cutout of the ground plane. Similarly, a PoDL pad connected to one or more inductors and a direct current (DC) power source is positioned in the cutout of the ground plane and is in series with the AC capacitor pad.

Abstract: A vehicle having a communication system is disclosed. The system includes two electrical couplings, coupled by way of a rotary joint having a bearing waveguide. Each electrical coupling includes an interface waveguide configured to couple to external signals. Each electrical coupling also includes a waveguide section configured to propagate electromagnetic signals between the interface waveguide and the bearing waveguide of the rotary joint. Additionally, the rotary joint is configured to allow one electrical coupling to rotate with respect to the other electrical coupling. An axis of rotation of the rotary joint is defined by a center of a portion of the waveguides. Yet further, the rotary joint allows electromagnetic energy to propagate between the waveguides of the electrical couplings.

Abstract: A device is provided that includes a first platform having a first side, and a second platform having a second side positioned within a predetermined distance to the first side. The device also includes an actuator configured to cause a relative rotation between the first platform and the second platform such that the first side of the first platform remains within the predetermined distance to the second side of the second platform. The device also includes a probe mounted to the first platform, and a plurality of probes mounted to the second platform. The device also includes a signal conditioner coupled to the plurality of probes. The signal conditioner may select one of the plurality of probes based on an orientation of the first platform relative to the second platform. The signal conditioner may then to use the selected probe for wireless communication with the probe on the first platform.
