Abstract: UAV tether systems are provided that reliably deploy and retract cables capable of high-power and high-bandwidth data transmission. The tether system spools cables in a single layer to promote heat dissipation thereby allowing the use of lower-diameter cables. The tether systems further utilize a lightweight converter that achieves a high-voltage power transmission across a cable that is stepped down to a plurality of lower-voltage outputs usable by a UAV and accompanying payloads. The converter is constructed in a manner that promotes heat dissipation through the use of multi-layer PCBs and separate power modules PCBs mounted above main PCBs to create a cavity where forced air can reach heat sinks affixed to the power modules that extend into the cavity.

Abstract: Disclosed is an universal radio interface system that allows different types of radios to be installed on a mobile or stationary platform. After a radio is installed, the radio can be efficiently removed and replaced with a different type of radio without having to change cabling, connectors, or mounting hardware. The universal radio interface can include an universal interface housing that can be mounted to the mobile or stationary platform. The universal radio interface also includes a radio tray that is installed in the universal interface housing. The radio tray is configured to accommodate specific types or sizes of radio modules. The universal radio interface system can also include a radio tray backing affixed to the radio tray and the radio module. The radio module, radio tray, and radio tray backing are assembled and secured within an interior cavity of the universal interface housing.
