Abstract: A communication system is disclosed. The system can include a first communication unit including a first antenna, a second communication unit including a second antenna and a dielectric waveguide cable, and a rotary joint configured to enable the first unit to rotate with respect to the second unit about an axis of rotation of the system. The dielectric waveguide cable can extend from the second antenna to the rotary joint, where a proximal end of the cable can be coupled to the second antenna and a distal end of the cable can be affixed to the second unit at a location bordering a space defined by the rotary joint. The first and second units can be configured to engage in two-way communication with each other. An axis of the distal end of the cable can be substantially aligned with the axis of rotation of the system.

Abstract: A vehicle having a communication system is disclosed. The system includes two electrical couplings, coupled by way of a rotary joint. 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 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: Aspects of the disclosure relate to cleaning rotating sensors having a sensor housing with a sensor input surface. For instance, a first signal indicating that there is a contaminant on the sensor input surface may be received. In response to receiving the first signal, a second signal may be sent in order to cause one or more transducers to generate waves in order to attempt to remove the contaminant from the sensor input surface.

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.
