Abstract: A technique for varying buoyancy of an apparatus includes providing a substrate configured to produce gas on demand when exposed to a liquid, exposing the substrate to such liquid, and capturing the gas produced by the substrate to increase the buoyancy of the apparatus within a fluid. In some examples, the liquid and the fluid contain the same material, such that gas may be produced using fluid already in the environment.

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: An aerial vehicle electrical power system for use with a tethered aerial vehicle, and related methods are provided. The aerial vehicle electric power system includes a plurality of light-emitting diodes (LED) carried by an aerial vehicle. At least one electrical circuit is carried by the aerial vehicle. The at least one electrical circuit has a DC buck converter electrically in series with at least a portion of the plurality of LEDs. A tether is connected between the aerial vehicle and a power source positioned remote from the aerial vehicle. Electrical power is transmitted to the aerial vehicle and at least a portion of the plurality of LEDs through the tether. The electrical circuit minimizes variances in power supplied to the aerial vehicle and the plurality of LEDs.
