Abstract:
A tree harvester includes a body and a harvesting system coupled to the body. The tree harvester further includes a control system coupled to the body. The control system is configured to receive data from the harvesting system regarding a characteristic of a harvested tree and control operation of the harvesting system based on the data. The harvesting system is configured to remove an intermediate portion of the harvested tree below a tree crown and graft the tree crown to a tree stump.
Abstract:
A mobile device includes a motion sensor configured to acquire motion data, a light sensor configured to detect an ambient light level and generate light data, and a processing circuit. The processing circuit is configured to receive the motion data from the motion sensor, receive the light data from the light sensor, analyze the motion data to determine displacement data corresponding to a displacement of the mobile device, analyze the light data to detect a light transition, and analyze the displacement data and the light transition to determine whether to initiate an action.
Abstract:
A cooling system for a subterranean power line may include a cooling tube configured to house a fluid. Heat generated by the subterranean power line may be radiated and/or conducted to the cooling tube and absorbed by the fluid within the cooling tube. As the fluid heats up, it may change phase from a liquid to a gas. The hot gas may rise to a heat-exchanging condenser configured to dissipate the heat and condense the fluid back into a liquid. The cool, condensed liquid my return from the heat-exchanging condenser to the cooling tube. Risers, gas transport tubes, pressure regulation systems, fluid storage tanks, and other components described herein may increase the efficiency of the cooling system and/or otherwise improve the viability of the cooling system for subterranean power lines.
Abstract:
A suppressor grid is configured proximate to an anode to produce a suppressor electric field selected to provide a force on an electron in a direction pointing away from the anode, wherein the suppressor electric field is further selected to pass electrons from the suppressor grid to the anode.
Abstract:
A system and method for repowering an unmanned aircraft system is disclosed. The system and method may comprise use of a utility transmission system configured to function as power system/source for UAV/aircraft and UAV/aircraft configured to interface with the power source/system. Systems and methods provide access and for administrating, managing, and monitoring access and interfacing by UAV/aircraft with the power system/source. UAV/aircraft system can be configured and operated/managed to interface with and use the power system/source (e.g. network of power lines from a utility transmission system) to enhance range and utility (e.g. for repowering and/or as a flyway or route). The system comprises an interface between the aircraft and the power source for power transfer; a monitoring system to monitor the aircraft; and an administrative/management system to manage interaction/transaction with the aircraft. The power source for power transfer may be a power line; power transfer to the aircraft may be by wireless power transfer (capacitive or inductive or optical) of an aircraft while at or operating along the power line. The aircraft may comprise a connector configured to interface with the power source/line; the power line may be configured to interface with the connector/aircraft. Data communications between the aircraft and system may be facilitated for interaction/transaction.
