Abstract: Systems, methods and computer-readable media are provided for controlling environmental conditions to control latent and sensible loads in a plant grow chamber. The density of plant-0 receptacles in the grow chamber is such that, when plants are held in the plurality of plant receptacles, evapotranspiration contributes to the latent load so that the latent load exceeds a sensible load, resulting in evapotranspirative cooling. This shift in the energy balance allows for greater energy savings, as compared with conventional indoor farms that focus on removing heat from the growth environment. Environmental conditions may be controlled to achieved desired conditions, such as the optimum ratio of harvest weight yield to energy consumption under given constraints. Light modules for enabling plant growth suitable for controlled environment agriculture are also described.

Abstract: This application provides a flexible and efficient way to handle escape symbols during decoding of N-tuple variable length codes (VLCs). The user can request that the decoder resolve a sequence of symbols. The Huffman lookup tables can contain a field to notify the decoder if a given N-tuple VLC includes an escape symbol. For non-escape symbols, as identified by the escape indicator bit in the Huffman lookup table entry, the decoder can finish resolving the N symbols of the N-tuple without requiring a symbol-by-symbol comparison of each symbol to detect escape conditions. For escape symbols, as identified by the escape indicator bit in the Huffman lookup table entry, the decoder can either look back to the user for help, or use pre-defined logic to resolve the escape symbols. Aspects of certain embodiments enable parallelism between Huffman symbol decoding and escape condition detection without losing future expandability.
