Abstract: Laser light emanates from optical components that are mounted on a substrate, each optical component being coupled to an optical fiber that delivers laser radiation combined from multiple lasers. A linear or elliptical holographic diffuser is located to diffuse the light emanating from the optical components. The laser wavelengths excite plant photopigments for predetermined physiological responses, and the light source intensities may be temporally modulated to maximize photosynthesis and control photomorphogenesis responses. Each laser is independently controlled.

Abstract: The present invention relates to the importance-directed geometric simplification of complex mesh-based representations of objects in virtual environments for radiosity-based global illumination simulations. By means of simplification, the time needed to solve the radiosity equation and so generate an accurate physically-based simulation can be markedly reduced. Further, geometric simplification is performed during the global illumination simulation process rather than as a preprocess step.

Abstract: A biological lighting system to provide temporally- and spatially-modulated photon flux output and spectral power distributions to plants on a circadian and circannual basis, or circadian and life cycle basis, to maximize effective and efficient growth in a horticultural setting. The photon flux or irradiance output and the spectral power distribution are modulated to match circadian and circannual rhythms, with individual or multiple luminaires controlled through one or more controllers. Different lighting spectra can be employed depending on the direction of illumination. The photon flux or irradiance output and the spectral power distribution may be set as best suited for any particular plant species, and the system is also useful for raising animals.

Abstract: In an example, an expected sky condition is calculated for a geographic location, a time of day, and a date based on a mathematical model. A predicted distribution of direct and interreflected solar radiation within the environment is calculated based on the expected sky condition. Measurement data from one or more photosensors is obtained that provides measurements of an initial distribution of direct and interreflected radiation within the environment, including radiation from solar and electrical lighting sources. A target distribution of direct and interreflected artificial electromagnetic radiation produced by electrical lighting is determined, based on the measurement data and the predicted distribution of direct and interreflected solar radiation, to achieve the target distribution of direct and interreflected radiation within the environment. Output parameters are set to one or more devices to modify the initial distribution to achieve the target distribution of direct and interreflected radiation within the environment.

Abstract: A predictive system and method thereof for indoor horticulture are disclosed. The method includes obtaining a set of input values identifying a geographic position of a physical structure enclosing an interior environment and a target distribution for environmental parameters for a selected plant occupant. The method further includes obtaining a virtual representation of the physical structure, and iteratively over time, updating the virtual representation based on actual plant growth or a predicted plant growth model for the selected plant occupant. The method further includes running a computational model to obtain a predicted distribution of the environmental parameters for the virtual representation, and determining a target distribution of artificially modulated environmental parameters. Based on the target distribution of the artificially modulated environmental parameters, the method includes setting output parameters for control devices to collectively control the actual distribution of the set of environmental parameters.

Abstract: A dense array of sensors positioned in a virtual environment is reduced to a sparse array of sensors in a physical environment, which provides sufficient information to a controller that responds to environmental conditions and parameters in the physical environment in substantially the same manner as it would to the same environmental conditions and parameters in the equivalent virtual environment. Data from a sparse array of virtual sensors is correlated with data from a dense array of virtual sensors and is used for generating control signals for hardware devices that influence a real or virtual interior environment. The correlated data and the control signals are used to train an artificial intelligence based controller that then controls the values of the parameters of the interior environment. A model of the interior environment is created using basic parameters in a computer-aided design application.

Abstract: Electric light sources typically exhibit temporal variations in luminous flux output, commonly referred to as “flicker.” Flicker, or temporal modulation, is known to influence the growth, health and behavior patterns of humans, and is also linked to growth, health and behavior patterns throughout the growth cycle of plants and animals. Control of peak radiant flux emitted by a light source to temporally modulate a light source will allow for the control of plants and animals for sustainable farming including but not limited to horticultural, agricultural, or aquacultural endeavors.

Abstract: The present invention relates to the real-time simulation of sound in three-dimensional virtual environments. In particular, a geometric method based on the principles of acoustic radiosity determines the room impulse responses of a virtual environment with arbitrary polygonal surfaces. The complexity of the method is of the order of the square of the number of patches that define the virtual environment. The room impulse responses are convolved with an audio signal and output through a speaker to simulate reverberation within the virtual environment, which corresponds to a physical environment.

Abstract: Visible light disinfection is a healthcare technology wherein violet light is used to inactivate pathogens such as bacteria, fungi, and viruses. The present invention overcomes the limitations of continuous irradiance in whole-room environments by pulse width modulation of the light sources and increasing the instantaneous irradiance while maintaining average irradiance and hence light power requirements. The invention further discloses the use of multispectral light sources wherein the pulse modulation frequencies are synchronized and the phase of the spectral components are offset in order to maximize synergistic or antagonistic responses to intracellular chromophore excitation.
