Patent number: 11476714Abstract: Systems and methods are described herein for providing wireless power to a mobile device, such as an aerial mobile device like an unmanned aerial vehicle (UAV). A navigational constraint model may prescribe a navigation path along which a wireless power transmission system can provide wireless power to the mobile device. Deviations from the prescribed path may require the mobile device to self-power. The prescription of a navigation path allows for the use of reduced-complexity wireless power transmitters that are fully capable of servicing the prescribed path. Multiple embodiments of prescribed paths with various limitations and features are set forth herein, along with multiple embodiments of wireless power transmission systems of reduced complexity and functionality to fully service the various embodiments of prescribed paths.Type: GrantFiled: May 6, 2019Date of Patent: October 18, 2022Assignee: Searete LLCInventors: Lawrence F. Arnstein, Daniel Arnitz, Jeffrey A. Bowers, Joseph A. Hagerty, Guy S. Lipworth, David R. Nash, Matthew S. Reynolds, Clarence T. Tegreene

Patent number: 11183887Abstract: System and methods are described herein for providing wireless power to a target device, such as a laptop computer, a mobile phone, a vehicle, robot, or an unmanned aerial vehicle or system (UAV) or (UAS). A tunable multi-element transmitter may transmit electromagnetic radiation (EMR) to the target device using any of a wide variety of frequency bands. A location determination subsystem and/or range determination subsystem may determine a relative location, orientation, and/or rotation of the target device. For a target device within a distance range for which a smallest achievable waist of the Gaussian beam of the EMR at an operational frequency is smaller than the multi-element EMR receiver of the target device, a non-Gaussian beamform may be determined to increase efficiency, decrease overheating, reduce spillover, increase total power output of rectenna receivers on the target device, or achieve another target power delivery goal.Type: GrantFiled: April 13, 2020Date of Patent: November 23, 2021Assignee: Searete LLCInventors: Daniel Arnitz, Jeffrey A. Bowers, Joseph A. Hagerty, Russell J. Hannigan, Guy S. Lipworth, David R. Nash, Matthew S. Reynolds, Clarence T. Tegreene, Yaroslav A. Urzhumov

Publication number: 20190215948Abstract: According to various embodiments, heat can be dissipated from a heat producing component mounted on a first side of a printed circuit board through a securing post extending out of the first side of the printed circuit board. The securing post can be configured to attach to a heat sink through a fastening mechanism. Subsequently, the securing post can transfer heat received from the heat producing component to the heat sink as part of dissipating the heat from the heat product component. The securing post can receive heat from the heat producing component through a printed circuit board heat transfer path integrated as part of the printed circuit board. The heat transfer path can include one or more thermal vias and one or more thermally conductive layers used to transfer the heat from the heat producing component to the securing post.Type: ApplicationFiled: January 9, 2018Publication date: July 11, 2019Inventors: Daniel Arnitz, Joseph Hagerty, Russell J.
