  • Publication number: 20200236870
    Abstract: A distributed sensor grid may be used to monitor the growth conditions of plants in an agricultural environment. In one example, a distributed sensor grid may include sensors that are arranged as a grid defined by a vertical axis and a first horizontal axis. The sensors may each be coupled to a cable and/or a port that provides operating power and/or network communications access. In some implementations, a plurality of lighting fixtures disposed in the agricultural environment may be configured to provide the power and network communications access to one or more sensors, thus alleviating use of excess cabling for connectivity and simplifying installation. The sensors may be correspondingly disposed within the vicinity of respective lighting fixtures to monitor growth conditions for a portion of the agricultural environment. The sensors used may also be packaged as an integrated sensor assembly, further simplifying installation and deployment.

  • Publication number: 20200163183
    Abstract: An integrated sensor assembly provides multiple sensing modalities to monitor an agricultural environment, and may be employed in or used with controlled environment agriculture (CEA) systems to control and maintain improved growth conditions for various plants. In one exemplary implementation, an integrated sensor assembly includes sensors to monitor parameters important to plant growth, such as a natural light sensor, an air temperature sensor, a relative humidity sensor, an air flow sensor, a carbon dioxide (CO2) sensor, and a remote infrared (IR) temperature sensor. The sensors are mounted onto a single circuit board, which is then placed inside a housing for protection from the ambient environment. The housing can include one or more openings and apertures to facilitate sensing with protective covers where appropriate. A USB port can be included to supply electrical power and transfer of data to and from the integrated sensor assembly (e.g., to provide plug-and-play functionality).

  • Patent number: 9491836
    Abstract: Methods and apparatus for determining the relative electrical positions of lighting units (202a, 202b, 202c, 202d) arranged in a linear configuration along a communication bus (204) are provided. The methods may involve addressing each lighting unit (202a, 202b, 202c, 202d) of the linear configuration once, and counting a number of detected events at the position of each lighting unit. The number of detected events may be unique to each electrical position, thus providing an indication of the relative position of a lighting unit within the linear configuration. The methods may be implemented at least in part by a controller (210) common to multiple lighting units of a lighting system, or may be implemented substantially by the lighting units (202a, 202b, 202c, 202d) themselves.

  • Patent number: 8938468
    Abstract: Methods and apparatus for facilitating a process of designing, selecting, and/or customizing lighting effects or lighting shows. A library of indexed (tagged) predefined lighting effects or shows is searched by a search engine, based upon information provided by a user/designer, to identify a set of effects or shows having attributes that are in some way related to the information provided by the user. The user is then presented with search results, i.e., a manageable subset of intelligently chosen lighting effects or shows, which may be ranked in terms of relevance, any one or more of which may be readily selected by the user. The user may select one or more effects or shows from the search results “as is” for execution by a lighting system, may combine one or more effects or shows from the search results, or may modify one or more effects or shows from the search results to refine some aspect of the effect(s)/show(s) in accordance with user preferences.
