Abstract: A ventilation system may include at least one air handler configured to supply an air flow to an enclosed grow zone and at least one heat pump coupled the at least one air handler and to at least one dry cooler. The at least one heat pump is operable in a first mode of operation in which a heat exchange fluid is cooled by the dry cooler and used to cool the air flow to remove moisture before the air handler supplies the air flow to the enclosed grow zone.

Abstract: An indoor growing facility includes an enclosed structure defined by one or more first walls and a growing shell defining a grow zone positioned in the enclosed structure. The growing shell defined by one or more second walls. The indoor growing facility also includes at least one environmental control component positioned inside the enclosed structure and outside the growing shell.

Abstract: An indoor growing facility includes a grow zone configured for growing crops and an air handling apparatus comprising a supply plenum wall at one end of the grow zone, and a return plenum wall at an opposite end of the grow zone. The return plenum wall may include intake openings that vary in size to create variable suction. The indoor growing facility may also include an irrigation system that includes an irrigation skid coupled to a supply tank, fertigation apparatus, and the grow zone. The indoor growing facility may also include a filtration system comprising an ozone apparatus, a regenerative filter apparatus, and a drum filter apparatus.

Abstract: In a general aspect, a method for transmitting data by inductive coupling can include applying, at a rate of a data-carrying signal, a plurality of bursts of a periodic signal to a tuned inductive antenna circuit. The method can also include producing, in the tuned inductive antenna circuit, an antenna signal. The antenna signal can generate a magnetic field. The method can further include delimiting an amplitude of each burst of the plurality of bursts of the periodic signal in accordance with an envelope signal having a rising edge and a falling edge. The delimiting the amplitude of each burst of the plurality of bursts of the periodic signal can include generating the plurality of bursts of the periodic signal using a set of points. The set of points can define, by discrete values, a burst of the plurality of bursts of the periodic signal.
