Abstract: An apparatus, system, and method for controlled-environment agriculture, including a closed-loop conveyor for transporting at least one container housing one or more plants to static or locally moveable service station(s) delivering at least one service in a sequential manner to plants on the conveyor and in parallel with other service stations for other services. A transition section conveys plants between an illuminated zone and a dark zone on FIFO basis. The conveyor cycle is computer programmable on a plant-by-plant basis for i) service station frequency and duration; and ii) illuminated zone/dark zone duty cycles for desired growth pattern and conveyor path routing based on sensor input to database. Different plant types at different growth stages are ‘interleaved’ on a same compact system (sensors, conveyor, and service stations) using artificial intelligence, deep learning, and computer vision for wide plant variety inventory management and programmed selective harvesting.

Abstract: Embodiments relate to a rotary internal combustion engine with a sealing structure that enables a rotor and a plurality of wings within a housing to form a plurality of sealed chambers. The wings are connected to the rotor and can rotate about a first axis with reference to the rotor, and the rotor can rotate about a second axis with reference to the housing, the second axis parallel to the first axis. As the rotor rotates within the housing, the wings follow a predefined path, causing the sealed chambers to change in volume. In some embodiments, each sealed chamber undergoes the intake, compression, power, and exhaust cycles of a four stroke engine.

Abstract: A gonioradiometric scanning apparatus and method for measuring the near and/or far field radiation pattern of radiating optical sources such as laser diodes (LD), light emitting diodes (LED), optical fibers, flat panel displays, and luminaires is described. The scanning apparatus incorporates a deflector for selecting an azimuth angle through the optical source to be measured, a rotating apparatus which collects light while scanning about the source, an optical commutator, and a detector. The rotating apparatus comprises a cylindrical hub and an optical collector using either an optical fiber or a train of reflectors, such as mirrors or retro-reflectors. The optical collector provides a means for both collecting light and for directing the beam emanating from the deflector to a place opposite the detector at which optical commutation occurs.
