Longitudinal axes of Patent 10,906,172 the rails are oriented parallel to each other and lie within a common plane or an uncommon plane. A method of forming a linear delta system includes mounting rails to a support frame, the rails having longitudinal axes that are parallel to each other and lying within a common plane, coupling a linear actuator to each of the rails, coupling a pair of parallel rods to each linear actuator, and coupling a platform to the pairs of parallel rods.Patent 10,906,172 granted 2/2/2021 to Anthony L. CrawfordMethods Of Recovering Rare Earth ElementsA method of recovering a rare earth element. The method comprises dissolving a rare earth element Patent 10,954,585 magnetic material in a dissolution organic solvent and a beta-diketone compound to form a dissolved rare earth element mixture. A rare earth element of the rare earth element magnetic material and the beta-diketone compound are reacted to form a beta-diketonate chelate complex and the dissolution organic solvent is removed. The beta-diketonate chelate complex is removed using a separation organic solvent, and the beta-diketonate chelate complex is recovered. Additional methods are also disclosed.Patent 10,954,585 granted 3/23/2021 to John R. Klaehn, Harry W. Rollins, Joshua S. McNallySystems, Devices And Methods For Communicating Data With Unmanned Aerial Vehicles Using An Underlay BroadcastingChannelAn unmanned aerial vehicle (UAV) and base station Patent 10,912,059 are disclosed that communicate within a first cell via schedule requests to set up transmission of uplink data. The UAV additionally communicates uplink data via a grant-free underlay broadcast channel to one or more neighboring base stations of the terrestrial cellular network. Transmitters, receivers, and related methods are also disclosed for modulation and demodulation of the transmission packets.Patent 10,912,059 granted 2/2/2021 to Hussein Moradi, Behrouz Farhang6'
