  • Patent number: 11364838
    Abstract: An agricultural work vehicle for operating in a field includes a chassis, a cab mounted to the chassis, a controller for controlling operation of the work vehicle, and a lighting system including a array field light. The controller is in communication with a field map input, and the array field light projects a light emission to illuminate a zone. A light control module is disposed in electrical communication with the controller and operably controls the array field light. Upon identifying an object in the field based on the field map input, the controller determines if the object is in the zone. If the object is in the zone, the light control module controllably adjusts an output from the array field light based on a location of the object in the zone.

  • Patent number: 11363708
    Abstract: A negative ion-based beam injector comprising a negative ion source and an accelerator. The ions produced by the ion source are pre-accelerated before injection into a high energy accelerator by an electrostatic multi-aperture grid pre-accelerator, which is used to extract ion beams from the plasma and accelerate to some fraction of the required beam energy. The beam from the ion source passes through a pair of deflecting magnets, which enable the beam to shift off axis before entering the high energy accelerator. The negative ion-based beam injector can be combined with a neutralizer to produce about a 5 MW neutral beam with energy of about 0.50 to 1.0 MeV. After acceleration to full energy, the beam enters the neutralizer where it is partially converted into a neutral beam. The remaining ion species are separated by a magnet and directed into electrostatic energy converters. The neutral beam passes through a gate valve and enters a plasma chamber.
